What To Do If Water Heater Is Not Heating?

what to do with a leaking water heater

Water heaters are built to last a long period, but even the greatest ones can develop leaks over time.A leaky water heater does not always indicate that it has to be replaced, but you should address any leaks as soon as they are discovered.The presence of even a tiny amount of water can do significant harm, thus it is critical to assess the situation immediately when it occurs.First and foremost, determine the source of the leak.

Even if a little quantity of water is visible below your water heater, it is possible that the water heater is not the source of the leak.Remove any standing water and assess the area.Are any of the fittings dripping or are there any other symptoms of leakage that you’re aware of?Make a thorough search of your surroundings for any other potential water sources.Where did you find the water?Was it near a window or another water pipe?

Keeping in mind the laws of gravity, if your floor slopes in any way, it’s possible that water went from another spot to where you discovered it.If you are unable to locate the source of the water straight away, place some paper towels where the water was discovered and check again in a few hours to a day or two.When you return, please The presence of damp towels indicates that there is a problem, and the water heater may be the source of the problem.If you’ve discovered that the source of the leak is your water heater, follow the steps below to assess the problem, or just give us a call and one of our highly trained professionals will come out to inspect the situation.


follow these steps to assess the situation

  • Water heater leaks should be addressed immediately by shutting down the water supply to the tank. On the cold inlet pipes of your water heater tank, there should be a specific shutdown valve for your water heater tank. If you have a gate-style valve (a valve with a rotating wheel), spin the valve as far clockwise as you possibly can.
  • If the valve is a ball-style valve, turn the handle 180 degrees
  • otherwise, turn the handle 180 degrees.

Turning off the water to your tank is suggested if you are experiencing a leaky water heater.On the cold inflow pipes of your water heater tank, there should be a specific shutdown valve.The valve should be turned clockwise as far as it can be, if it is a gate style valve (a wheel that spins).If the valve is a ball-style valve, turn the handle 180 degrees; otherwise, turn the handle 90 degrees.

Electric Water Heater

It is recommended that you turn off the power at the breaker before working on the water heater tank if you have an electric water heater and are having trouble with it. Simply turn off the circuit breaker.

Gas Water Heater

  • For gas-powered water heaters that are leaking, we recommend that you turn off the gas supply before attempting any repairs. On the gas line going to the tank, there should be a specific gas shut-off valve to prevent the flow of gas. See the image below for a visual representation of a gas water heater being turned off. Once your water and electricity have been switched off, you will be able to more accurately analyze the problem and discover where the leak is coming from in more detail. Check the input and output connections. Leaks are frequently found at the points where pipes connect to your water heater. Examine the connections for the cold water input and hot water output. Is there a problem with any of the fittings? It’s possible that all they require is to be tightened using a pipe wrench.
  • Make that the pressure release valve is working properly.
  • If there is an excessive buildup of pressure, the pressure relief valve, also known as the T&P valve, may be activated to discharge water as a safety precaution. It is possible that pressure will build up at the valve if your thermostat is set too high or if the water pressure to your home is excessive. Check your thermostat settings to ensure that the temperature is not set too high. A pressure gauge at a hose bib may be used to check the pressure in your home (you can also check the pressure in your car). What temperature setting should you use for your water heater? The Department of Energy suggests that you set your tank-based water heater to 120 degrees Fahrenheit instead of the default setting of 140 degrees Fahrenheit that most manufacturers use. There are two possibilities when it comes to water leaking from a T&P valve: either the valve is performing its function properly by releasing water as pressure develops, or the valve itself is defective. However, if your thermostat is not set too high and you are still experiencing leakage, the issue may be with the valve itself
  • check your water pressure. Besides checking the pressure and temperature, it’s a good idea to check the humidity. You may check the pressure by attaching a pressure gauge to the hose bib outside your home and running it through it. What should I do if my incoming pressure is excessive? According to regulations, your inbound water pressure should not be greater than 80 PSI, and if the pressure is greater than 100 PSI, we highly recommend that you install a pressure decreasing valve. Not only might your water pressure be producing a leak, but it could also be causing damage to your fixtures.
  • Look at the bottom of the water heater for leaks.
  • Identifying the cause of a leak might be challenging in some cases, particularly if water is pooling underneath the tank itself. It’s possible that water leaking from a valve will run down the sides of the tank, creating the appearance that it’s coming from the bottom while in fact it’s coming from the top or sides. Alternatively, if the leak is coming from the bottom of the tank, it is possible that the tank itself is damaged, in which case it will need to be replaced.
  • Make that the drain valve is working properly.
  • The drain valve, which is located towards the bottom of the tank, should be entirely closed, so ensure sure there is no water flowing from this place. If it is leaking, it is possible that the washer inside has become worn and has to be replaced. If you are still unable to locate the source of the leak, please contact us and one of our professionals will be able to assist you
  • No matter what you discover, it is always recommended that you have a professional evaluate your water heater if you discover any leaks.

When your water heater specialist arrives to begin work, they will drain your tank. However, if your tank is leaking excessively, you may want to drain it promptly to avoid water damage to your property. The following actions should be followed if you need to empty your water heater before a professional arrives: After you’ve shut off the water and electricity, follow these steps:

  1. Connect a garden hose to the drain valve at the bottom of the tank and run it outside on the ground to remove the water. Make certain that the tank is drained to an appropriate area, such as a gutter drain or a sink. It is not recommended to discharge the water onto your lawn or driveway since the silt and rust from the tank might hurt your grass and discolor your driveway.
  2. Activate the drain valve that is connected to the hose.
  3. Pulling up on the pressure release valve on the tank’s top will allow it to be opened.
  4. Allowing the water in the tank to drain is recommended.

Again, unless you are concerned about catastrophic damage to your home, you do not need to be concerned about draining your water heater.If you need assistance, our professionals would be pleased to assist you.Following these initial procedures after discovering a leak can be quite beneficial in preventing water damage from accumulating.Any inquiries or concerns you may have should be sent to (866) 264-9642, which is our toll free number.

Loose Drain Valve:

Lagging drain valves in water heaters are one of the most prevalent causes of water heater leaking. Try tightening the valve with a wrench until it is snug, but be cautious not to over-tighten it if water appears to be flowing out.

Too Much Pressure:

It is possible for a water heater tank to build up excessive pressure, which might result in leaks. This can happen if the water temperature is adjusted too high or if the water pressure from the outer water source is too high for the tank to handle.

Cracked Storage Tank:

Hot water heaters are constructed using a storage tank that is coated with glass.Over time, the natural minerals in the water might calcify and deposit on the interior of the tank, causing it to get clogged.These have the potential to fracture the glass lining of your water heater, causing it to leak.Additionally, water expands when it is heated.

Over time, this expansion places stress on the heater’s glass lining, which might eventually lead it to crack and break.Unfortunately, if this occurs, your hot water heater will need to be replaced since the breaks in the glass liner are irreparable and cannot be repaired.Occasionally, these leaks will not have an impact on the performance or functionality of the device, and the individuals who experience them will choose to wait to replace the water heater.Providing the leaking water does not cause damage, this is OK, but the unit will need to be replaced at some point in the future.

Other Reasons:

Your water heater may be leaking for a variety of reasons, including broken fittings, poor draining, and just old age. Performing some troubleshooting on your own is always a good idea, but calling in a professional will always be the safest and most effective method to avoid any long-term and expensive damage to your property.

Your Water Heater Isn’t Producing Hot Water

If your hot water heater is no longer supplying hot water and the tank is supplied by electricity, check to see if the fuse at the breaker has blown and that the breaker has not been reset.Whether you have a gas hot water heater, you may also check to see if the pilot light is still lit to see if the heater is still operational.If neither of these basic solutions are successful, contact to schedule a service call with a skilled technician to come to your house and assess the situation.

My Gas is Leaking – I Smell Gas!

If you suspect a gas leak at the water heater, you can shut off the gas at the dedicated gas shut off valve located on the gas line leading to the water heater and turn off the water heater.If you suspect that you have a gas leak concern that has not been resolved, you can contact Fast for service at (866) 264-9642.It is usually recommended to notify your energy company as soon as possible in the event of a significant gas leak or emergency.

After an Earthquake, Protect Your Home

  • If you smell gas, move the meter to a safe location outside your home. Turn the gas valve 14 times from the ON position to the OFF position.
  • Make contact with your natural gas business.

Having to deal with a leaky water heater first thing in the morning is not the best way to start the day. It is possible to avoid an emergency from turning into a disaster, though, by following these procedures.


13 Common Water Heater Problems (Tricks to Fix)

Modern water heaters are meant to last for a long period of time.The majority of them come with lengthy warranties, and you hope to be able to use them without issue for many years in the future.The combination of heat, water, and all of the many components that make them function, however, will always result in issues.Many problems with your heater are not life-threatening, and the key to repairing them is accurately diagnosing what is wrong with it.

Here are our top 13 water heater problems – along with some advise on how to address them – to aid you in your diagnostic process.

Before you start

There are many different types of water heaters available, including ones that run on gas and those that run on electricity.You should use extreme caution while working with an electric water heater since they are high-voltage equipment.Before you begin working on the heater’s electrical components, be certain that the power has been switched off – this involves turning off the breaker for your heater at the service panel – before you begin.Another precaution you should take is to use a voltage tester to check all of the wires before you start working with them.

It is possible that failure to do so will result in significant harm or perhaps death.

1. No hot water

In the event that you are experiencing no hot water, there are various probable causes, and you must work through each of them carefully in order to eliminate each one – and this will also depend on whether you have an electric or a gas-powered heater.In the most obvious case, an electric heater is unable to function because no electricity is being supplied to the heater.Begin by looking for tripped circuit breakers and resetting them if they are still in place.If this has happened, there is a simple solution: simply switch the computer off and on again.

It is possible that you may need to replace the fuse if it has blown.The next step is to verify that the high-temperature cutoff is operational.Open the panel and hit the red ″reset″ button to restart the system.Check to see whether the water is now able to warm up.You might also have a heating element or components that are malfunctioning, which is another option.These should be tested and replaced if necessary.

If, after testing each of them, you are still unable to identify the source of your lack of hot water, it may be necessary to seek expert assistance.Ensure that the gas valve is open if you are using a gas space heater or heater.If this is not the case, you may be experiencing difficulties with the pilot or the burner.Check out numbers 10, 11, and 12 below to discover how to deal with these problems.

2. Not enough hot water or water not hot enough

When it comes to not having enough hot water, the explanation for this will vary depending on the sort of water heater you have.The problem with your heater if it has a tank might be as simple as the tank being insufficiently large for your purposes.If your tank is too small for the amount of people who will be showering, for example, you may run out of hot water before everyone has done their showering.If this is the case, you should consider investing in a new water heater that can accommodate your requirements.

If your heater previously provided enough hot water for everyone but has abruptly stopped or is no longer capable of heating the water enough, the problem is most likely due to a faulty heating element.Examine them and replace them if required.Another fast cure is to check the thermostat — you may just need to raise the temperature by a few degrees.Also keep in mind that, during the winter, you may need to raise the thermostat setting since the groundwater you are heating comes at a lower temperature than in the summer.If you have a tankless heater, you may be trying to run more fixtures than the unit’s power can handle.Check the manufacturer’s specifications to see how many fixtures the unit can handle.

You might be experiencing difficulties because your heater is not strong enough for your needs.Tankless heaters must also work harder in the winter, so if you are experiencing this issue during the colder months, it is possible that this is the cause of your problem.Upgrades to a more powerful unit may be necessary in your situation.

3. Water too hot

That the thermostat has been set too high is almost probably the cause of the problem, but it is a simple problem to fix.Simply reduce the temperature on your thermostat and you should be set to go.The temperature pressure valve should be checked if this does not solve the problem; if it is malfunctioning, the heater will not shut off when it reaches the proper temperature.This is a potentially dangerous condition, and you will need to replace the valve as soon as you possibly can.

4. Water takes too long to heat

That the thermostat has been set too high is almost probably the cause of the problem, but it is a simple one to fix.Simply reduce the temperature on your thermostat and you should be OK.It is possible that the temperature pressure valve is malfunctioning; if this is the case, the heater will not shut off when it reaches the proper temperature.This is a potentially dangerous scenario, and you must replace the valve as soon as possible.

5. Low water pressure

Low water pressure is frequently caused by a lack of sufficient width in the pipes.Pipes in older homes are typically 12 inches in diameter, but pipes in newer homes are often 3 inches in diameter.If you live in an older house and are experiencing low water pressure, it is possible that the problem may not stem from the boiler at all.Instead, you may need to consider installing bigger pipes in your home to remedy the problem at hand.

6. Leaks

Leaks can occur as a consequence of loose connections, in which case you will need to tighten them using a wrench to prevent further damage. They can also emanate from valves, which can be changed if necessary. If the leak originates from the tank, the situation is more serious since the tank may be rusted. Corrosion will cause your tank to fail completely, and you will have to replace it.

7. Dirty water

If the color of your water begins to change to a nasty rust, you are most likely dealing with corrosion within your tank. The only way to fix this is to replace the tank entirely. However, it is possible that the problem is caused by a failing anode rod; thus, before replacing the tank, flush the tank and replace the anode rod to see whether this resolves the issue.

8. Smelly water

If your water has a foul odor, it is possible that bacteria in your heater is to blame.This is especially prevalent if your water is obtained from a well, as it is in most cases.Flushing your tank may be beneficial, or you may try boiling the water to the highest temperature possible to eliminate all of the bacteria.It may be necessary to wipe it out with chlorine bleach if this does not work.

The stench of rotten eggs in your water might be caused by a malfunctioning anode rod, in which case you should replace it immediately.

9. Tank makes noises

It is possible for water heaters to create noise for a variety of reasons.As the water heats up, rumbling, popping, and banging sounds are produced by a build-up of scale in the tank and on the heating components.This is the most prevalent cause of the noises.If this is the case, emptying and descaling the tank may be necessary.

To avoid this problem from arising in the first place, you should totally flush the tank out every few months to keep it clean.Depending on how serious the situation grows, you may be forced to replace the tank entirely.Because of the usual expansion and contraction caused by heat, water heaters and pipes might create noise from time to time.This is completely safe, but there isn’t much you can do to prevent the noise.

10. Pilot doesn’t light

There are a variety of reasons why you may be experiencing problems with your pilot light.If it won’t light in the first place, it might be because the pilot light orifice or tube is blocked – or it could simply be that the pilot light needs to be replaced.Another possibility is that the thermocouple is defective or has come away from its socket.It is also possible that there is air in the gas line or that the gas valve is malfunctioning.

11. Pilot lights and then goes out

If the light comes on but then goes out, the reasons for this might be the same. It is possible that the thermocouple has to be replaced, that you have a defective gas valve, or that the vent has been clogged.

12. Burner goes out

This is most likely a similar issue to the one that was causing the pilot light to malfunction. It might be caused by a clogged orifice, a fault with the thermocouple, or a clogged orifice and vent.

13. No hot water for bathtub

Even if you have no difficulty utilizing your shower or operating a dishwasher or washing machine, you may be experiencing difficulties getting hot water to run a bath.The issue might stem from your heater’s design.If you have a tankless heater, this is most likely the source of the problem.Tankless water heaters heat water as it runs through them, providing you with an endless supply of hot water on demand at all times.

However, if the water passes through the system too rapidly, it will not have enough time to heat up properly.Showers and other uses do not necessitate such a big volume of water, thus the water will be heated to the temperature you anticipate it to be.The water flow required to operate a bath, on the other hand, is significantly higher, and your tankless heater may simply not be able to keep up with it.If this is the case, you will need to look into other options for heating your bath, since your tankless unit will not be able to provide you with the hot water that you require.

Identify the problem early

The sort of heater you have may be the source of the problem if you have no trouble utilizing your shower or operating a dishwasher or washing machine but cannot obtain hot water to run a bath.Most likely, this is the core reason if you have a tankless heater.Because they heat the water as it passes through them, tankless heaters provide a virtually limitless supply of hot water on demand at all times.But if the water moves through the system too rapidly, it will not have enough time to warm up.

Water is heated as expected in showers and other applications since they do not necessitate such a high flow rate.In contrast, the water flow required to operate a bath is far higher, and your tankless heater may just be unable to keep up.If this is the case, you will need to look into other options for heating your bath, as your tankless unit will not be able to provide you with the hot water you will want.

Troubleshooting Checklist for an Electric Water Heater

Electric water heaters have a similar appearance to their gas-fueled counterparts.In order to limit heat loss from the heated water, they both employ an insulated steel storage tank jacket, with insulation between the storage tank and the tank jacket.The primary difference between electric and gas water heaters is the source of heat used to heat the water.Electric upper and lower heating elements protrude into the water tank of an electric water heater, and the water is heated as it passes through them.

Gas water heaters contain a gas burner that heats the water from below the tank, which is where the tank is located.In most cases, a faulty heating element, which is a cheap and relatively simple component that can be easily replaced, is to blame for problems with electric water heaters that provide little or no heat.Other issues may arise as a result of incorrect settings, excessive household water pressure, or a failure to perform regular tank maintenance.

Watch Now: How to Repair an Electric Water Heater

Check the Warranty

Limited warranties are provided with both residential and commercial hot water heaters.Every tank is equipped with a rating plate that displays the tank’s model and serial number.These numbers specify the year in which the tank was manufactured, and they will decide if the tank is covered by a prorated warranty, which may include the provision of a new tank or replacement parts at no cost or at a discount.Take a picture or write down the information, then contact the manufacturer if the tank is leaking or the element is not working correctly.

Field labor is not covered by the manufacturer’s warranty.The following is something that you can perform before you start diagnosing the issue.


Working with electric water heaters when the power is on is risky since they are high-voltage (240-volt) equipment that can cause electrocution.Turn off the electricity to the water heater’s circuit by turning off the relevant breaker in your home’s service panel before inspecting any electrical components of the water heater (breaker box).Check all of the wires in the water heater using a non-contact voltage tester to ensure that the power has been turned off before touching any of the wires.

How to Fix

No Hot Water

A water heater that does not generate hot water might be due to a lack of electricity, a tripped limit switch, or one or more faulty heating components, to name a few possibilities.As a first step, make sure that the circuit breaker for your water heater is not tripped on your panel of electrical circuit breakers.Switch off the circuit breaker and then turn it back on if it has been tripped.If the heater’s breaker does not trip (i.e., if it is still turned on), attempt the following steps to reset the high-temperature limit:

  1. Turn off the circuit breaker for the water heater’s circuit at the service panel if necessary.
  2. Removing the access panel for the water heater’s upper heating element is a good idea.
  3. Carefully remove all of the insulation and the plastic safety shield, taking care not to come into contact with any of the wires or electrical connections
  4. To reset the high-temperature cutoff, press the red button above the higher thermostat, which is positioned above the upper thermostat.
  5. Reinstall the safety guard, the insulating material, and the access panel.
  6. Turn on the circuit breaker for the heater.
  7. Test each heating element and replace it if required if this does not resolve the problem

Inadequate Hot Water

If your water heater is producing hot water but not enough of it, it is possible that your unit is too small to satisfy the hot water demands of your home. Take precautions to ensure that the water heater’s capacity does not exceed the demand.

How to Fix

The water heater should be able to provide hot water to a capacity of 75% of its total capacity.For example, a 40-gallon water heater is appropriately suited for a 30-gallon demand.If the demand exceeds the capacity of the heater, attempt to restrict the length of showers, install low-flow showerheads, and spread out dishwashing and laundry to different times of the day rather than doing them all at the same time to reduce the strain on the heater.The failure of one or both of your unit’s heating elements, even if your unit is not undersized, might indicate that one or both of its heating elements have failed.

When taking a shower, a steady supply of lukewarm water is suggestive of a faulty top heating element in the shower.When hot water runs out rapidly during a shower, it is an indication of a faulty bottom heating element in the shower.

Water Temperature Is Too Hot

When there is too much hot water, it may be almost as annoying as when there is not enough hot water. If you’re encountering this problem, it’s possible that one or both of the thermostats on your water heater are set too high.

How to Fix

To double-check the thermostat settings, do the following:

  1. In the service panel, turn off the electricity to the water heater to conserve energy.
  2. The access panel, insulation, and plastic safety shield from each heating element on the water heater should be removed before continuing. Do not come into contact with any wires or electrical terminals.
  3. Using a non-contact voltage tester, check the cables to ensure that the power has been turned off.
  4. Ensure that the heat is set correctly on both thermostats: Both of them should be at the same temperature as each other. 115 to 125 degrees Fahrenheit is the acceptable temperature range.
  5. Make use of a flathead screwdriver to adjust the temperature to the correct level
  6. and
  7. Set the other thermostat to the same temperature as the first
  8. For each element, replace the safety guard, insulation, and access panel as needed.
  9. Turn on the circuit breaker for the heater.

Water Leaks

Water leaks are often caused by leaking valves and plumbing connections, but they can also be caused by difficulties with the tank’s drainage system. Water leaks may cause substantial damage to a property, therefore it is critical to get the leak repaired as quickly as possible when it occurs.

How to Fix

Leaks from water heater tanks can occur as a result of faulty heating components or corrosion in the tank.Inspect the elements for looseness and, if required, tighten them with an element wrench to prevent them from moving.A rusted tank is unable to be repaired and must be completely replaced instead.Turn off the water heater’s electricity and water supply, and then thoroughly drain the tank to stop the leaks from happening again.

Rust-Colored Water or Bad Odor

If your water has a brown, yellow, or red tinge to it as it comes out of the faucet, corrosion might be occuring within your water heater tank or in the pipes in your home.If your water comes out smelling like rotten eggs, it’s possible that bacteria has built up in the tank of your hot water heater.A professional plumber may be required to replace the anode rod in the tank, which is something that you should avoid doing unless absolutely necessary.

Tank Making Noises

Is your water heater making noises?If so, what are they?Is there a low rumbling or popping sound when you turn it on?What if it’s a high-pitched whine instead?

It’s possible that the sounds you’re hearing is the sound of boiling water.When there is a significant amount of sediment building in the bottom of a tank, it can cause the bottom of the tank to overheat, which can result in the water boiling.

How to Fix

In order to remove the silt from the tank, the first thing to attempt is to empty it. The tank may need to be replaced if this does not alleviate the problem.

How to Troubleshoot a Water Heater Not Heating

See if you can determine why your water heater is failing to heat the water in your house.It can be aggravating to be without hot water, especially during the winter months.In most cases, an absence of hot water happens as a consequence of the whole amount of hot water in the tank being used up-for example, by running both the washing machine and dishwasher at the same time, as described above.However, if it is not the source of the problem, it is not difficult to troubleshoot your water heater and identify the source of the problem.

Step 1

Check the circuit breakers in your fuse box to make sure they are working properly. This means that if the fuse has burned out or the circuit breaker that directly controls the electricity for your heater has tripped, your heater will not function. Turn off and on your water heater by resetting the circuit breaker or replacing the fuse as needed.

Step 2

Take a look at the temperature setting on the thermostat. It is possible that the temperature is set too low, which is an issue during the winter months when the temperature of the incoming water is already quite low. Increase the temperature setting on the thermostat to a higher setting.

Step 3

Check the status of the pilot light by removing the burner access covers and opening them. If you have a gas-powered water heater, and the pilot light goes out, the water will not be heated until the pilot light is restored. Screwdriver open the covers and check for one little flame at the bottom of the casing. If it’s out, try re-igniting it.

Step 4

Examine the pipes leading to the water heater. Unless the pipes that transport hot water throughout your home are leaky, you will not be able to obtain a sufficient volume of hot water to flow through your taps. To locate the source of the leak, look for pools of water on the floor or listen for a dripping sound on the ceiling.

Step 5

Keep an eye out for differences in the color of the water that comes out of your faucets. If the water is discolored, it is conceivable that there is a buildup of sediment in the water heater, which is preventing the water from being hot enough to drink. To ease the problem, drain the tank entirely and rinse it out with clean water many times.


If you do not have any prior expertise repairing a water tank or if the situation necessitates the services of a certified plumber, contact them.


Turn off the electricity to your water heater to avoid the danger of an electrical shock from occurring.

Why is My Water Not Getting Hot?

As I will demonstrate in this piece, troubleshooting a water heater that is not heating water is a simple process.The new part will be inexpensive and simple to install even if you have to replace a whole component.This is a symptom that the thermostat, heating element, or reset button on an electric water heater is not functioning properly.Another possibility is that a power surge has caused a circuit breaker or a fuse to trip, resulting in the failure of the device.

Most electric water heaters will feature two thermostats and two heating elements, which will be located at the top and bottom half of the storage tank, respectively.On the top of the thermostat is a button that allows you to reset it.This mechanism, also known as an emergency cut off (ECO) or high temperature limit switch, shuts down the water heater’s power supply when water temperature surpasses 1800 degrees Fahrenheit, which occurs after the thermostat setting has been exceeded.A reset button that constantly tripping may be caused by a shorted heating element, a broken thermostat, loose wiring, or it may be problematic in its own right.When the water temperature in the water heater reaches 1800 degrees Fahrenheit, the reset button trips, resulting in the water heater being turned off.When this occurs, the heating element will turn off and the water will stop heating.

Ensure that the circuit breaker or fuse has not tripped or blown on your electric water heater if it is not heating the water.Testing for continuity across the thermostats, heating elements, and reset button using a multimeter will determine whether the water heater is receiving 240 volts of electricity.If it is, turn off the power and check for continuity across the thermostats, heating elements, and reset button.Replace any damaged or worn out components.

If you have an electric water heater that is not heating up, you will need a multimeter, a flathead screwdriver, and a Philips screwdriver to diagnose the problem.I also advocate wearing safety glasses and wearing hand gloves for your own protection.

How to Troubleshoot And Fix a Water Heater that is Not Heating

It is necessary to follow a systematic approach while troubleshooting and repairing an electric water heater that is not working. Start by looking for the most accessible locations, and once you’ve eliminated those options, go on to the more difficult to reach locations. To troubleshoot and repair an electric water heater that is not heating, follow the steps below.

1. Test the Power Supply

You should check to see that the water heater is receiving electricity before proceeding any further.A properly functioning water heater should be supplied with 240 volts of electricity.To determine whether or not your electric water heater is getting electricity, remove the junction box cover located at the top of the water heater and measure the voltage across the two wire terminals using a multimeter, as shown in the illustration.It is not necessary to remove the wire nuts at this time.

Simply insert the multimeter probes into the nuts and read the results on your multimeter.Simple as that.If you can establish that the water heater is receiving sufficient electricity, the problem is likely to be limited to the heater connections and not the heater itself.It’s most probable that your thermostat, heating element, or reset button is malfunctioning.The opposite is true if there is no electricity coming to the water heater; in this case, there is an issue with your electrical connection.Most likely, a tripped water heater breaker or an overheated fuse is to blame for this problem.

2. Inspect the Circuit Breaker

  1. If you don’t know where your main electrical panel is, it’s most likely in the basement, garage, or in a storage closet, depending on where you live.
  2. When you open it, search for the breaker that is labeled ″Water Heater″ or the initials ″WH.″ Check to see whether the circuit breaker has tripped.
  3. When there is a power surge or a dangerous situation in the water heater, the circuit breaker for the water heater will trip, preventing the risk from occurring.
  1. The circuit breaker for the water heater should be reset to the ON position if it has been tripped.
  2. In certain cases, this may be sufficient to resolve the issue at hand.
  3. A issue with the heating element, thermostat, or reset button will almost certainly cause the circuit breaker to trip back to the off position instantly or within a few minutes.
  4. Before you begin working on the water heater, double-check that the electricity to the water heater has been turned off fully.
  5. Operating the water heater with 240-volts of electricity running through it can be quite harmful.

3. Remove the Thermostat and Heating Element Access Panels

  • As I previously stated, an electric water heater would most likely have two thermostats and two heating elements, as opposed to one gas water heater. The top and lower heating components, as well as the thermostats, are masked by a metallic cover plate, which is attached to the water heater with screws to keep them hidden. Remove the upper access panel first, then the screws that hold it in place using a screwdriver. Keep the screws and cover plate in a safe location until you need them. Keep an eye out for a little piece of insulation that will be visible once the panel has been taken off the wall. You have two options: either completely remove the insulation or secure it to the tank with duct tape.
  • Remove the protective plastic cover plate from the top of the machine. Water heaters with a plastic cover that snaps on to protect the thermostat and heating element are available in some models. It should be removed as well.
  1. The heating element, thermostat, reset button, and thermostat temperature adjustment dial can all be seen now that the above-mentioned items have been removed from the way.
  2. There are a sequence of screws and wires connecting the thermostat to the rest of the component, whereas there are just two wires and two screws connecting the heating element to the rest of the piece.
  3. There are six sides to the heating element’s head, and it is threaded into the water heater.
  1. Most water heater reset buttons will be red in color and will be situated on the thermostat, above the heating element, in the majority of cases.
  2. They will also be clearly labeled as a result of this.
  3. You’ll also notice the thermostat temperature adjustment dial, which appears like a large plastic screw on the side of the device.
  4. It will also include indications indicating the temperature adjustment range from the lowest to the maximum.

4. Check the Reset Button

  • A reset button on a water heater serves as a safety feature. It identifies a problem with the water heater connections and shuts down the electricity by tripping the circuit breaker. It goes without saying that if your water heater’s reset button is tripped, the water heater will immediately stop heating water. The first thing you want to look for is whether or not the reset button has been triggered in this case. It is likely that a tripped reset button has popped out. In order to restore functionality to a water heater reset button that has been tripped, push and hold the button until you hear a click. If it doesn’t click, push and hold it for at least 5 seconds to force it to do so. It is possible that the reset button itself is defective. It is necessary to test for continuity in order to determine if it is excellent or bad. Continuity is a simple measurement that determines whether a circuit is open or closed. An open circuit indicates that the component under test is not allowing power to pass through it, whereas a closed circuit indicates that the component under test is allowing free passage of current. First, grab your phone or digital camera out and snap a picture of the reset button, thermostat, and heating element connections before doing anything else. You will be able to recall where each wire was connected later on if you do it this manner.
  • Make sure that all of the cables are disconnected from all of the screws.
  • Make sure you have your multimeter ready. Make sure that the dial on your analogue multimeter is adjusted to the lowest possible value in ohms of resistance. Set the calibration by pinching together the two probes, and then bringing it to the zero reading.
  • Set your digital multimeter to the lowest ohms of resistance setting
  • however, if you have the tone option (represented by a microphone symbol), set your digital multimeter to that level as well.
  • Ensure that you pay close attention to the location of the reset button. There will be two screws on the left and two screws on the right of the door
  • Make a measurement of resistance across the left terminals by placing each probe on a screw, and then perform a similar measurement across the right terminals
  1. The value on your multimeter should be zero for both tests if your reset button is in excellent working order.
  2. If you get any other figure than that, the reset button is defective and will require repair or replacement.
  3. In order to repair a water heater reset button, you will also need to replace the water heater thermostat.
  1. Get the thermostat’s model number and use it to purchase a replacement.

5. Test the Thermostat for Continuity

  • A water heater thermostat is in charge of determining when to switch on and off the heating element based on the temperature of the water within the water heater. A defective thermostat, on the other hand, will fail to switch on the heating element. Usually, when you have no hot water at all, this indicates that your higher thermostat or heating element is malfunctioning. A faulty lower thermostat or heating element is to blame for hot water that runs out too quickly. The following steps will show you how to check the continuity of a water heater thermostat: Turn the thermostat adjustment dial all the way up to the highest position with a flathead screwdriver.
  • When you look at the thermostat, you will notice a set of four screws (terminals). The resistance across the left terminals should be measured with a multimeter first, then the resistance across the right terminals.
  • Adjust the temperature adjustment dial to the lowest setting once again using the flathead screwdriver.
  • Repeat the above-mentioned test.

It is necessary to have a zero ohm resistance value on your multimeter for both of the tests described above. If you receive more than that, you very certainly have a faulty thermostat, which you will need to repair or replace immediately.

6. Test the Heating Element for Continuity

  • While the water inside the tank is being heated, the upper heating elements exchange with the lower heating elements in a clockwise fashion. These elements, on the other hand, do not last indefinitely. They have the potential to burn or short, and if this happens, you will no longer have access to hot water. An electrically shorted heating element indicates that the element is in contact with the tank body, in which case the element will be grounded. The following is an example of how to check for continuity in a water heater element: Heating elements have two terminals, each of which has two screws and wires linked to it.
  • Disconnect the two wires from the screws with a wire cutter.
  • Make use of your multimeter to measure the resistance between the two connectors.
  • It is recommended that a decent heating element has a resistance of between 10 and 16 ohms. If you are unable to obtain a reading on your multimeter, the heating element must be replaced. Continue to use one multimeter probe to make contact with one terminal while using the other probe to make contact with the tank body.
  • Repeat the method outlined above, but this time with the probes and terminals in contact in the other direction.

Getting a reading on your multimeter indicates that the heating element is actually grounded, and that it is necessary to replace the element.

7. Test the Lower Thermostat and Heating Element

  • Once you have finished troubleshooting the upper thermostat, heating element, and reset button, you may go on to the lower access panel for further investigation. Remove the cover plater, insulation, and plastic cover from the vehicle.
  • As you will see, the lower thermostat only has two terminals, as opposed to the upper thermostat’s four.
  • Unplug the cables that are attached to the thermostat and the heating element.
  • The highest setting on the temperature reset dial should be used
  • Determine whether or not there is continuity between the two thermostat terminals.
  • Reduce the temperature dial on the thermostat to the lowest possible level
  • Make another attempt at the exam. If the results of both tests are zero ohms, then the tests were successful.
  • After that, check for continuity in the bottom heating element. In addition, you should look for a value between 10 and 16 ohms during this test
  • otherwise, the heating element is faulty.

8. Replace the Thermostats

  • The process of replacing a malfunctioning thermostat is simple! All you have to do now is make certain that you are changing the correct one. Personally, I like to get a pair and change both the top and lower ones at the same time. It is kept in place by a metal bracket located at the bottom of the water heater
  • Check to be that all cables have been unplugged from all of the screws before proceeding.
  • Remove the old thermostat by carefully pulling the bracket out of the way.
  • Insert the replacement thermostat while you’re still pulling the bracket out.
  • Wire the wires to the screws and fasten them all together.
  • Check to see that the reset button has not been pressed.
  • To set the water heater temperature dial on the thermostat to your chosen settings, press the button on the thermostat.
  • Return the plastic cover, insulation, and metal cover plater to their original locations.
  • Turn on the water heater’s power supply.
  • Wait 20 minutes for the water to reach its maximum temperature.

9. Replace the Heating Elements

  • Again, I prefer to replace both heating elements at the same time because it ensures that I will not have to replace the other good heating element in a few years or months. Close the shutoff valve for the cold water supply. This is due to the fact that you will need to drain the tank.
  • A garden hose should be connected to the drain valve located at the bottom of the tank. Using a flathead screwdriver, open and close the valve. Wait for the tank to completely empty
  • The drain valve should be closed and the garden hose should be disconnected once the tank has been completely drained.
  • To remove the water heaters, loosen them with a 1 12 inch socket wrench and pull them out. You may want to remove the sediment from your water heater tank before replacing the heating element if the tank is full of sediment. More information may be found on this subject here.
  • Insert a washer on the new element (this is extremely crucial) and thread the element into the tank as shown before. Using the socket wrench, tighten it down.
  • Turn on the cold water supply valve if it is not already on. To keep air from accumulating, turn on the hot water faucet closest to your location. Once the faucet has stopped spitting air, turn it off.
  • Make a visual inspection for leaks around the connecting points for the heating element. Even if there aren’t any, you may still connect the wires to the screws and fasten them all together.
  • Start by turning on the water heater’s electricity.
  • In 20 minutes, check to see if the water has been sufficiently heated.

This is essentially how to troubleshoot and repair a water heater that isn’t heating up. If you don’t feel confident in your ability to do the repair yourself, don’t hesitate to contact a qualified plumber for assistance. It will, however, come at a cost to you!

Why Is My Hot Water Heater Not Heating?

  1. You’ve probably experienced the sensation of being sprayed with ice-cold water after stepping into a shower.
  2. While attempting to escape away from the ice-cold shower water, you may leap, scream, and maybe even take down the shower curtain.
  3. The worst times to identify a problem with your hot water heater are when you’re trying to take a hot shower after a hard day at work or in the middle of the night.
  1. Let’s take a look at why your hot water heater might not be heating and what you can do to keep from getting sick from being cold.

What Type of Water Heater Do You Have?

  1. The majority of residences are equipped with either a gas or an electric water heater.
  2. They heat water in distinct ways, which means they have separate troubleshooting methods if you aren’t getting hot water from your faucets or showerheads when you have both types.
  3. If you are unsure about the sort of water heater you have, consult the owner’s handbook for further information.
  1. If you are unable to locate the instructions, seek for a flue.
  2. A flue will be present on a gas water heater, which will allow the exhaust gases to escape.
  3. In order to have a gas water heater installed in a residence, this is necessary.
  4. An electric water heater will be powered by an electrical cord, and it will not have a flue or a vent.
  5. Gas water heaters might be more difficult to diagnose and repair than electric water heaters.

If you are not a skilled troubleshooter, you can hire A.B.May to assist you.

Do You Rent or Own?

  1. If you rent an apartment or a house, contact your landlord or property management as soon as you find that your hot water heater isn’t heating the water correctly.
  2. The majority of rental houses will have a tank water heater or a standard water heater installed – nothing particularly high-end in terms of performance.
  3. These individuals are in charge of repairing problems such as heat loss from the water heater or issues with the dishwasher or laundry not receiving enough hot water to function properly.
  1. When renting from homeowners or property management organizations, you don’t want to take the chance of inflicting more harm than good to the situation.

The Most Common Water Heater Not Heating Issues

Gas or Electric Issues

  1. Knowing that if you’re the last person to go into the shower, you may receive a chilly or lukewarm shower as a result of the individuals who came before you using up endless amounts of hot water.
  2. Whether you discover that you have no water due of a leak in the shower, check other taps in the house to see if you have hot water in other parts of the house at the same time.
  3. If you have no hot water anywhere, it’s possible that you have a problem with your water heater.
  1. If you have a gas water heater, you should check to see if there are any problems in the neighborhood.
  2. Check the propane levels in the water heater if it is powered by propane.
  3. Check all of your gas appliances; if none of them function, it’s likely that you have a gas leak.
  4. In order to find out why, contact your gas company.
  5. You should double-check that your electric water heater hasn’t been accidentally turned off or that the fuse hasn’t gone out before using it.

Replace the fuse or re-energize the circuit breaker and attempt again.If you discover any additional problems with the energy in your home, you should contact the electric provider.

A Thermostat on the Fritz

  1. While water heater thermostats are generally less prone to failure than other types of thermostats, they can still fail.
  2. Depending on the model, they can either fail completely or fail so slowly that it takes a long time to realize how cold your water is getting.
  3. When you turn on your water heater, check to see whether the reset button pulls out.
  1. If it does, this might signal that your water is growing hotter than 180 degrees.
  2. This indicates that the thermostat may be malfunctioning.
  3. Try pressing the reset button a second time and waiting a few hours to see if it pops out again.

Pilot Light or Ignition Issues

  1. A pilot light will be used by a gas water heater, whereas an ignition will be used by an electric water heater.
  2. In natural gas ignitions, there are hybrids of this type as well.
  3. If your pilot light goes out and cannot be re-lit, it is possible that there is a gas leak in the water heater’s gas pipes.
  1. The failure of your electric ignition to start might be caused by a defective ignition or electrical problems with the device.
  2. The need for a plumber to come out and examine the problem might be caused by a variety of factors, ranging from faulty equipment to an obstructed sensor.

Temperature and Pressure-relief Valve (TPR) Failures

  1. If your TPR valve breaks, the pressure from the water pipes and sewage lines might build up within the water heater, causing it to overheat and fail.
  2. This valve assists in the cooling of the water heater if it becomes overheated.
  3. If this fails, it is possible that the water heater will explode if the correct conditions are present at the time.
  1. Annual inspections and checks should be performed on the TPR valve to verify that it is not capped off, clogged, or suffering from any other faults that might result in an explosive explosion.

Loss of Water Pressure

  1. When there is a decrease of water pressure, the water in your home behaves strangely throughout.
  2. For your water heater, if there is excessive water pressure in the lines going to the tank, the TPR valve may open and begin to discharge the extra pressure.
  3. Because it is attempting to manage the pressure within the water heater, this might cause your water heater to begin leaking in severe circumstances.
  1. An extension or storage tank may be necessary if your home is experiencing water pressure decrease, as this will aid in controlling the problem and preventing water damage.

Water Heater is Old

  1. As your water heater ages, loose parts, nuts, bolts, and other components may become loose and produce complications that result in it failing to heat.
  2. If you notice any leaking, no matter how minor, it may be as simple as tightening some sections of the system to prevent it from continuing.
  3. If you feel that the age of your water heater is a contributing factor to heating problems, or if you see leaks while the unit is not heating, it may be time to consider replacing the unit.

Basic Troubleshooting Steps for a Hot Water Heater Not Heating

If you’re having problems with your hot water heater not heating, you may try the following measures first before contacting A.B. May:

Check to see if there are any gas or power problems in your region. This might be as simple as contacting the gas or electric provider to inquire about their products and services.

  1. Ensure that the pilot light is lighted on a gas water heater
  2. otherwise, replace the water heater. If you are confident in your ability to do so, try to relight the candle.
  3. Ensure that the fuse in your breaker box is not damaged when dealing with an electric water heater. It has to be replaced, flipped, and then tested to see whether it resolves the problem.
  1. Inspect every faucet and shower in your home to see whether there is a problem with hot water across the entire house or only in one portion of the house.
  2. If the unit has a reset button, use it to try to reset it. For instructions on how to do this, consult the manufacturer’s directions for your individual item.
  3. Inspect the water heater thoroughly for evidence of corrosion, loose components, leakage, and other concerns that might be causing it to fail to heat water
  4. if necessary, replace the water heater.

Take a look around the area where your water heater is located for any evidence of water damage. Even though there is no ongoing water damage, it is possible that there was a leak in the past, which has contributed to the current problem.

Keep in mind that these are not all-inclusive troubleshooting procedures. It’s possible that anything went wrong during the installation process or during general usage. If your electric or gas water heater isn’t heating the water, consult the owner’s handbook or schedule a house visit with A.B. May to find out how to fix the problem properly.

How to Troubleshoot a Water Heater

  1. Hot water is a need, but it’s one that’s sometimes overlooked.
  2. We rely greatly on the availability of hot water.
  3. From taking daily showers to bathing the dog to reducing the amount of time we spend in the kitchen.
  1. However, we rarely consider how much we rely on our hot water until something goes wrong with it.
  2. A defective water heater is more than just an annoyance when it occurs.
  3. It may result in serious water damage to your floors, walls, furniture, and even your pocketbook if not addressed immediately.
  4. So, what should you do if your water heater isn’t performing as it is supposed to?
  5. The purpose of this tutorial is to show you how to troubleshoot a water heater.

What to Do If You Have No Hot Water (at All)

  1. In the event that you have no hot water, this is one of the most obvious symptoms that something is wrong with your water heater.
  2. It should be noted that the primary function of a water heater is to heat water.
  3. There’s something wrong if it’s coming out of the oven cold.
  1. In reality, there’s a good chance that there’s an issue with your electricity, your thermostat, or your heating components.
  2. Check to verify that the circuit breaker for your water heater has not been tripped before putting on your DIY gloves.
  3. With your service panel, you can determine whether or not there has been a power failure.
  4. If this has happened, simply turning the computer off and on again should remedy the issue.
  5. If your water heater hasn’t tripped yet, it’s time to reset the high temperature limit on the device that controls it.

This is not nearly as difficult as it appears to be.In reality, changing the temperature limit on your water heater is as simple as following these 5 steps:

  1. To turn off the power to your water heater, go to your service panel and turn off the breaker. The fact that you haven’t turned off this feature is critical before proceeding to the next stage.
  2. The access panel and insulation should be removed together with the safety guard, with care taken not to touch any terminals or wiring during the process.
  3. Locate the reset button for the high-temperature cutoff. Typically, you’ll locate it above your higher thermostat, where it’s a bright red color. Once you’ve located it, click on it.
  4. Reinstall the safety guard, insulation, and access panel at this point.
  5. Restart your water heater a second time if necessary.

My Hot Water Is Too Hot

  1. Being unable to use hot water because it is too hot is just as annoying as not having any hot water at all.
  2. It might also be dangerous, therefore it’s critical that you understand how to troubleshoot your water heater in order to resolve the problem of overly hot water.
  3. It’s possible that the settings have been set too high in this case.
  1. To make the necessary adjustments, follow these steps:
  1. Again, you’ll need to turn off the power completely
