What To Do If Hot Water Heater Is Not Working?

9 Common Reasons Why No Hot Water (Tips to Fix)

Is your water heater not producing as much hot water as it should?Alternatively, does the hot water heater take an excessive amount of time to heat the water?When the machine stops producing hot water, many people find it quite aggravating.Fortunately, you can resolve this issue as soon as it arises.However, it is recommended that you determine the source of the problem in order to correct it.

In order to help you, we will explain why there is no hot water supply and how to have it restored in this article.

General Tips When No Hot Water on Electric and Gas Water Heaters

Allowing your water heater a couple of hours to reheat the water in it is one of the most straightforward solutions to solve this problem when there is no hot water in the house.Most of the time, a tankless water heater’s hot water supply will run out owing to excessive use of the unit.If this is the case, turn off your water heater for a couple of hours to allow it to reheat.However, if you are still unable to obtain hot water after attempting this procedure, it is possible that the problem is with another component.Using a water heater that comes with a tank, the problem may be caused by the tank’s overall size.

When compared to larger systems, smaller water heater tanks do not conserve as much water.Choosing the proper size hot water tank can be challenging because there is such a large selection available on the market nowadays.If you have a large family, you should look into what size hot water tank will be the most appropriate for your needs.

Why No Hot Water from Gas Water Heater

1. Water Heater Has No Gas Supply

Most of the time, a big issue is the availability of natural gas.If you discover that you have no hot water despite the fact that your gas water heater is turned on, verify the condition of your gas supply.It’s possible that you accidentally switched off the gas supply without realizing it, or that the switch off button has a malfunction.As soon as this occurs, turn your gas on to ″pilot″ and remove the cover that covers the pilot light and the burner.

2. No Pilot Light

  • If you no longer see a flame, this indicates that your pilot light has been turned off. When this occurs, all that will be required of you is to relight the candle. However, you should be aware that the majority of modern heaters do not come with pilot lights any longer. Instead, they use glow plugs or spark ignitors to ignite the fuel. If this is the case in your situation, you may need to seek professional assistance or attempt to repair the problem yourself by consulting the owner’s handbook. If your water heater is equipped with a pilot light, carefully inspect it to see if there are any instructions printed on the light. If you are unable to locate any, try the easy technique listed below! While you’re waiting for the gas to disperse, turn off the regulator for at least 5 minutes and maybe longer. Switch your regulator to the ″pilot″ position thereafter.
  • If your water heater has a self-igniting feature, you should push and hold the ignition knob for at least 60 seconds before turning it on again. To complete the process, turn your regulator to the ″on″ position
  • if it is necessary, all you will need is an ordinary long lighter to re-ignite the pilot light. Light the lighter while aiming it toward your pilot burner, which is located at the end of the gas supply tube. Using this procedure, you should be able to turn on your pilot light again.

It is important to note that if the pilot light does not light up, check to verify if the gas input valve is open.When in doubt, turn the gas inlet valve handle to the same distance as the gas line to ensure that it is working as it should.After you’ve allowed the gas to flow in, try lighting your pilot once again.The thermocouple may be defective if the pilot light does not come on after repeated attempts to ignite it.If you discover this problem, pick up the phone and call the gas utility provider, which will take care of it at no cost to you.

3. When There Is a Gas Leak

Pure gas is colorless and odorless in its original condition, and it emits no odors.In order to better detect gas leaks, a gas-related chemical known as mercaptan is injected to the gas stream.As a result of the addition of this substance, gas tends to smell like rotten eggs or sulfur when a leak occurs.If you smell gas in the vicinity of your unit, turn off or lock the gas valve immediately.With a downward press on the gas valve, you may shut off the gas supply.

If the gas valve is damaged, it is necessary to repair it.

Guides for Electric Water Heater

4. Tripped Breaker

Check to see if there is a button on the electric water heater that has been accidentally depressed.After that, check to see whether the circuit breaker has been tripped by checking the circuit breaker box.Breakers that have failed to trip may not be in the opposite direction from the others, but they will be out of alignment.If it has been tripped, all that is required is that you switch it off and on again.This will solve the problem by resetting the device.

However, if the breaker trips again even after you have reset it, you should contact a reputable electrician.All of the circuit breakers in the water heater must be in good working order for it to function effectively.If yours has a defective circuit breaker, contact an electrician as soon as possible.

5. Faulty High-Temperature Cutoff Switch

It is one of the most common reasons why you are no longer able to get hot water into your house when the high-temperature cutoff switch trips.You may correct the situation by turning on the light and pressing a button.You will hear a clicking sound when you press it, and then power will be restored to the water heater.If the power does not come back on, it is likely that the high-temperature cutoff is malfunctioning and has to be repaired or replaced.

6. A Flooded Compartment

Having water in the compartment indicates that water has made its way into the compartment. If water seeps inside the thermostat, it has the potential to cause problems.

7. Faulty Heating Elements

It is possible that the heating components are one of the factors contributing to the lack of hot water in your home. Water heaters have a 10-year lifespan, and it is preferable to get a new one rather than repair an old one. Nonetheless, if you need to replace your heating components, make sure to completely switch off your water heater before starting the process.

8. Look For Possible Water Leaks

Water leaks may be the primary reason for the absence of hot water supply difficulties in the first place in some situations. When you are experiencing a problem with your hot water, keep an eye out for water leaks.

9. Defective Thermostat

The top thermostat of an electric water heater regulates the temperature of the bottom and higher heating components. A malfunctioning thermostat will result in a lack of hot water. If the lower thermostat is not functioning properly, your hot water will not be hot enough. Fixing your thermostat will assist you in resolving your hot water issues.

Water Heater Can’t Keep Up to Your Home Needs

If your water heater is operating normally but is unable to satisfy your household’s hot water demands, you should be aware of the steps you should take to avoid a situation like this.Learning to manage the issue is sometimes the best course of action, however you may always get a larger water heater if the circumstance calls for it.Here are two excellent suggestions to assist you keep the hot water running even when your water heater is unable to keep up.

a). Limit Your Usage

An typical shower uses 40 liters of water every 60 seconds, which is a significant amount of water.It is possible to run out of hot water at any time if the size of your water heater tank is only 50 gallons or less.A water heater tank with a capacity of 70 gallons will not be able to provide more than 43 gallons of hot water.The reason for this is because when cold water is introduced into the tank, it dilutes the hot water.With this in mind, you should only utilize a portion of your hot water rather than the entire supply.

b). Know the Recovery Time

When your water heater is drained, it will require some recovery time before it will be able to distribute hot water as efficiently as before.It normally takes a few minutes or hours for the body to recuperate (depending on your tank size).For example, it will take around 26 minutes to replenish and heat a 70-gallon tank of drinking water.In order to obtain hot water as quickly as possible, avoid using hot water while the recovery process has not been completed yet.Allowing the unit to heat the water more quickly will result in the device heating the water more quickly.

Drawing water while the recovery process is still in progress will result in the addition of chilly water to the tank.When this occurs, the recovery period will be prolonged, and the water will not be sufficiently warmed.

c). Loose Connections

Electrified water will cease to work correctly if the unit’s wiring becomes tangled or otherwise compromised. As a result, switch off the machine and double-check that all of the wiring is still in place. This is a problem that is uncommon to meet, but it is one that should be taken into consideration.

d). Broken Tank

If the wiring of the device gets loose, the electric water will cease to operate effectively. In order to ensure that the complete wiring is still in place, turn off the unit and inspect it. Although this is a condition that is uncommon, you should keep it in mind.

Wrap Up

It is possible for a water heater to stop supplying hot water for a variety of reasons.Continue to be vigilant, though, and always seek a solution to a hot water problem whenever it arises.With the information in this page, you should be able to identify the problem and resolve it before it becomes too bad.Is there anything more you want to ask or say?Please do so if you have any comments or questions for us to answer!

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

  1. The water heater should be able to provide hot water to a capacity of 75% of its total capacity.
  2. For example, a 40-gallon water heater is appropriately suited for a 30-gallon demand.
  3. 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.
  4. 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

  1. Leaks from water heater tanks can occur as a result of faulty heating components or corrosion in the tank.
  2. Inspect the elements for looseness and, if required, tighten them with an element wrench to prevent them from moving.
  3. A rusted tank is unable to be repaired and must be completely replaced instead.
  4. 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

  1. 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.
  2. 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.
  3. 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

  1. Is your water heater making noises?
  2. If so, what are they?
  3. Is there a low rumbling or popping sound when you turn it on?
  4. 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.

13 Common Water Heater Problems (Tricks to Fix)

  1. Modern water heaters are meant to last for a long period of time.
  2. 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.
  3. The combination of heat, water, and all of the many components that make them function, however, will always result in issues.
  4. 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

  1. There are many different types of water heaters available, including ones that run on gas and those that run on electricity.
  2. You should use extreme caution while working with an electric water heater since they are high-voltage equipment.
  3. 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.
  4. 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

  1. 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.
  2. In the most obvious case, an electric heater is unable to function because no electricity is being supplied to the heater.
  3. Begin by looking for tripped circuit breakers and resetting them if they are still in place.
  4. 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

  1. When it comes to not having enough hot water, the explanation for this will vary depending on the sort of water heater you have.
  2. The problem with your heater if it has a tank might be as simple as the tank being insufficiently large for your purposes.
  3. 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.
  4. 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

  1. That the thermostat has been set too high is almost probably the cause of the problem, but it is a simple problem to fix.
  2. Simply reduce the temperature on your thermostat and you should be set to go.
  3. 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.
  4. 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

Among the possible causes of water taking a long time to heat are malfunctioning heating elements, silt buildup on the components, and a malfunctioning thermostat, among others. Ensure that you check each of these items in turn and replace them as necessary. If you have a gas-powered model, the problem might be due to the burner – see12 for more details.

5. Low water pressure

  1. Low water pressure is frequently caused by a lack of sufficient width in the pipes.
  2. Pipes in older homes are typically 12 inches in diameter, but pipes in newer homes are often 3 inches in diameter.
  3. 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.
  4. 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

  1. If your water has a foul odor, it is possible that bacteria in your heater is to blame.
  2. This is especially prevalent if your water is obtained from a well, as it is in most cases.
  3. Flushing your tank may be beneficial, or you may try boiling the water to the highest temperature possible to eliminate all of the bacteria.
  4. 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

  1. It is possible for water heaters to create noise for a variety of reasons.
  2. 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.
  3. This is the most prevalent cause of the noises.
  4. 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

  1. There are a variety of reasons why you may be experiencing problems with your pilot light.
  2. 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.
  3. Another possibility is that the thermocouple is defective or has come away from its socket.
  4. 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

  1. 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.
  2. The issue might stem from your heater’s design.
  3. If you have a tankless heater, this is most likely the source of the problem.
  4. 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

Often, the most essential thing you can do is recognize an issue as soon as possible and take efforts to resolve it as soon as possible. If you ignore the situation, it will only worsen and will almost certainly result in you having to pay more money in the future. And now that you’ve read this guide, you should have a solid sense of where to begin your search.

Even if a problem with your hot water heater requires the services of a professional, you may be capable of repairing it yourself.Our experts have put together a list of common problems with hot water heaters, as well as instructions on how to remedy them.

Water Heater Problems & Solutions

Loose or Damaged In-Line Valve

  1. In contrast to a water leak in the bottom of your water tank, a water leak on the top of your system may be quickly and simply resolved.
  2. A faulty in-line valve is one of the most prevalent causes of water tank leaks.
  3. Water flow may be activated or deactivated using this handle, which is placed at the top of the water tank and is designed to do so.
  4. In order to resolve this issue, you will need to tighten the nut that keeps the ball or in-line valve in place.

If the leak gets more serious after the fitting has been tightened, you will need to visit your local hardware shop to purchase a new in-line valve for your water heater, which will cost you around $30.

No Warm Water

  1. If you have an electric water heater in your house, the most common reason of a lack of warm water is a faulty heating element, which may be repaired or replaced.
  2. Your water heater is equipped with two heating elements, each of which is responsible for heating the incoming water in the water tank to a comfortable temperature.
  3. After a heating element begins to fail, you will have little to no hot water to use for showering, cleaning, or doing laundry once the problem is identified.
  4. On the other hand, there are a range of issues that might prevent the generation of warm water from a gas water heater from functioning properly.

An out-of-service pilot light or a defective gas valve are also possible causes of this problem.A thermocouple that has failed in your home may potentially be responsible for a shortage of hot water in your home.With the purchase of replacement components, each of these components may be quickly and simply replaced.It is recommended that if your hot water heater is not functioning properly that you either purchase replacement components or call a certified plumber for assistance with water heater repair.

Low Supply of Hot Water

  1. Do you find yourself running out of hot water on a regular basis?
  2. Having a fractured dip tube may have resulted in this problem.
  3. Designed to move cold water to the base of your water tank so that it may be heated, this tube is a need.
  4. A fracture or hole in the dip tube may begin to appear when the incoming supply of cold water is discharged towards the top or center of your tank.

Consequently, the cold water stored on the tank’s top will be distributed to the faucets and showers around your home.You will only be able to resolve this hot water heater problem by replacing the dip tube in your system.Because the procedure of installing a new dip tube is complicated, we recommend that you get assistance from a professional expert.Excess sediment accumulation in your water tank may also be a contributing factor to a lack of warm water supply.The minerals in water, such as magnesium and calcium, will begin to accumulate at or near the bottom of the water heater’s tank as it approaches the middle of its life cycle.As the minerals continue to increase in size, the amount of space available in the water tank for storing hot water will diminish.

In order to remedy this issue, you should cleanse your water heater to eliminate the surplus minerals.

Water is Too Warm or Cold

  1. It is possible to modify the temperature of your shower water if the water seems too hot or too cold in your shower by adjusting the settings on your thermostat.
  2. Increasing the temperature to 120 degrees Fahrenheit may allow you to save money on your power costs in the long run.
  3. In the event that you are concerned about burning or skin irritation, this is an appropriate temperature to employ.
  4. Is this temperature a little too chilly for you?

You may also lower the temperature of your shower to 140 degrees Fahrenheit to make it more enjoyable to shower.Changing the temperature of your hot water heater does not cause it to operate, and this is an indication that your thermostat has failed.Find a competent plumbing or heating contractor in your region as soon as possible to repair or replace your outdated thermostat.

Low Water Pressure

  1. Low water pressure is not usually the result of a faulty water heater, as previously stated.
  2. The flow of water will be regulated before it reaches the skins in our kitchen or bathroom if you reside in an older home with smaller water pipes.
  3. The only method to completely address this hot water heater problem is to install new 34 inch water pipes in your system’s distribution system.
  4. Calcium deposits in water pipes are another sort of issue that can have a detrimental influence on your water pressure.

Water lines will get narrower in diameter when magnesium and calcium begin to build in them as a result of the formation of these minerals.Water from your water heater will be unable to reach your sinks or appliances in a time-efficient manner as a result of this.Because the procedure of replacing water pipes entails the removal of drywall, a typical homeowner who does not possess a plumbing license will not be able to resolve the hot water heater problem described above.More information may be found at: 3 Different Types of Furnace Vents and How They Work

Discolored Water

  1. The water that comes out of your sink in your home should be crystal clear.
  2. Do you have water that is discolored in your residence?

Hot Water Heater Not Working? Here Are 5+ Reasons

  1. Every home is equipped with a water heater, which works tirelessly and continuously throughout the day to ensure that we always have hot water when we turn on the tap.
  2. These appliances, like any other large household equipment, are not indestructible and can experience difficulties much like any other large home appliance.
  3. Today, we’ll take a look at some of the most typical problems that individuals have when their water heaters stop operating.
  4. These can range from really simple repairs to potentially expensive replacements, so we’ll look at a variety of probable reasons in this section.

There is no need to be alarmed because the majority of frequent water heater problems are simply remedied.Let us begin by discussing why it is so critical to have a properly running water heater in the first place.

Hot Water Heater Not Working: Overview

  1. A hot water heater that isn’t operating properly might be caused by a variety of factors, which we shall discuss later.
  2. For the time being, let us consider why a water heater is so vital.
  3. Without a properly operating water heater, your home will be without hot water in all of its many locations.
  4. This implies that you will not be able to take warm showers or wash your hands under heated faucets.

When it comes to regular life, these are extremely inconvenient and a pain to cope with.However, more significant problems might occur that are far more harmful than simply not being able to take a warm shower..Problems might be as simple as a little leak, or they can be considerably more serious and have far-reaching repercussions.Just to be on the safe side, it is critical to take action as soon as you see any signs of issue with your water heater.Simple things like an incorrectly turned control valve might be the only thing you need to examine.Regardless of the problem, let’s take a look at some of the potential problems that your water heater might be experiencing and how to resolve them.

Hot Water Heater Not Working: What to Do

Water Heater Not Getting Hot

  1. The water heater in your home is plainly malfunctioning if you are attempting to use a faucet to obtain hot water and only cold water is coming out.
  2. While this may appear to be a significant problem, it is actually one of the most straightforward concerns to resolve when it comes to water heater malfunctions.
  3. The first thing we can do to figure out what’s wrong is to check to see whether your circuit breaker is malfunctioning.
  4. Because most contemporary units rely on electricity to operate (this is true even if your water heater is fueled by natural gas), they will not create hot water unless a power source is connected to them.

When in doubt about whether this is the problem, ensure that the electricity flowing to your water heater is turned on by checking the circuit breaker for the water heater.It signifies that the breaker has tripped, and you should turn the power back on to the heater after checking for any defective wiring.If the switch is not turned on, it means that the breaker has tripped.If that isn’t the problem, it’s possible that one of the heating components has malfunctioned.A specialist will be required to come and replace any of these items if they fail to function properly.The temperature dial can also be checked for signs that the water was too hot and destroyed the element or that it was too hot and caused the circuit breaker to trip.

Hot Water Heater Not Working: Too Little Hot Water

  1. The lack of sufficient hot water is a very minor inconvenience.
  2. Typically, the thermometer incorporated into the water heater is to fault when the water heater does not heat up to a sufficient temperature.
  3. After reaching a specified temperature, this instructs the heater when to cease producing water.
  4. Temperature should be raised by a minimal amount under typical conditions; however, be aware that higher temperatures are frequently required in the winter to keep the water warm.

Another possibility is that you have used up all of the water that can be kept in your tank and are experiencing a shortage.Following the usage of a full tank, these tanks need around 30 minutes to reheat a full tank, which would explain the lack of hot water if you had just used a lot of hot water.

Strange Sounds

  1. Due to the fact that a water heater has virtually no moving parts, there should be no noise emanating from them.
  2. If you notice your water heater hissing or producing unusual noises, it’s time to call a professional to inspect it.
  3. The most typical source of noises originating from a water heater is air becoming trapped in the tank as a result of silt building in the tank.
  4. It is possible for silt to accumulate in a water heater, which will then hold onto air that will be released when the tank heats up.

This silt may be avoided by cleaning your tank on a regular basis, about once a year, to eliminate any sediment.Flush the tank thoroughly to get rid of the noise, and if the sound persists, contact a professional.

Strange Smells

  1. Strange odors emanating from your water heater or plumbing system might indicate a number of problems.
  2. That the tank is filthy is the most apparent thing that we can deduce from this.
  3. This can be caused by sediment buildup caused by hard water, or in more severe cases, it might be caused by corrosion.
  4. Clean out the heater by rinsing it with water to remove any debris, and then replace the anode rod.

If the peculiar scent persists after cleaning and replacing the anode, corrosion is likely to have occurred, and you may need to replace the tank totally.Remember that if your water heater is fueled by gas and you notice a suspicious rotten egg-like odor in your house, you should vacate your home and notify emergency authorities right once.This might indicate the presence of a natural gas leak, which can be quite dangerous.


  1. Leaking is a rather clear symptom of a problem, but it does not always indicate the end of your tank’s life.
  2. Check the tank thoroughly and attempt to determine where the leak is coming from.
  3. The tank itself cannot be repaired (you will need to replace the water heater), but you may fix pipes and other difficulties that have arisen as a result of the leak.
  4. As previously said, the anode element of your water heater may be replaced, and this may be the source of the problem.

Due to the fact that it can be difficult to detect a leak unless you specifically seek for it or notice considerable water loss, you should ensure that you are checking on your water heater on a regular basis to ensure it is in proper operating condition.Any leaks that occur in a tankless water heater are significantly more economical to repair than leaks in an electric water heater.If your water heater is electric and tankless, any leaks that occur will be in the pipework.

Unnaturally-Colored Water

  1. The last thing you want in your water or on your skin is water that has been contaminated by corrosion or microbes of any kind.
  2. When you use your hot water, it should be quite clear whether the water has an unusual appearance or if it has an unusual taste.
  3. Several difficulties might cause this, ranging from a small annoyance to the need for a complete replacement of the device.
  4. Once again, it is possible that the anode that is installed in your tank is corroding and causing the water to get contaminated.

This is a simple enough patch that should take care of the issue.If the unusual hue persists, washing out the tank and testing the flushed-out water for excessive minerals and silt that might cause discoloration of the water should be considered.If colored water continues to emerge in the tank, it is likely that there is corrosion within the tank.A professional opinion on this topic, as well as many others, will provide you with a more precise response than just attempting to examine it yourself will ever be able to do.

8 Things to Consider If You Have No Hot Water in Your Home

  1. As soon as you turn on the faucet or the shower, you anticipate hot water to flow out of it.
  2. Finding yourself with no hot water and having to take a chilly shower with water gushing out may be a frustrating experience in more ways than one.
  3. Beyond the shock of the ice cold water, you may begin to worry about the energy efficiency of your water heater or whether there is a natural gas leak in your home.
  4. Before you let your thoughts to go to the worst-case scenario, remember that there are a variety of reasons why you may be experiencing no hot water in your house.

To begin troubleshooting, determine if your home is equipped with a gas or an electric water heater.Here are some of the most prevalent causes of water difficulties, as well as some solutions.

1. Leaking Tank

  1. In order for a water heater to function properly, there must be sufficient water in the tank.
  2. If there is no hot water, it is most likely due to a leak in the water heater tank.
  3. An empty tank poses a major threat to the environment and is extremely inefficient in terms of energy usage.
  4. Examine the connections between the appliance and its valves, as well as the connections between the appliance and its pipes.

If those are secure, go to the compartment containing the tank.The most likely scenario is that there is water in the compartment and the appliance has to be replaced.

2. Gas Leak

  1. A natural gas leak emanating from your water heater is not only inconvenient, but it is also potentially hazardous.
  2. As soon as you believe that natural gas is leaking, contact your local gas provider for assistance.
  3. The expert from the gas company is knowledgeable and kind, but his primary concern is not the repair of your hot water heater.
  4. The following stages will be determined by his evaluation of the equipment.

If there is a natural gas leak, the gas company will investigate the problem and come up with a remedy within their jurisdiction.The troubleshooting process will proceed if there is no gas leak discovered.

3. Electric Water Heater Malfunction

  1. When it comes to your water heater, energy efficiency is critical to consider.
  2. Both an electric and a gas water heater can be beneficial in ensuring that you don’t wake up to find yourself without hot water in your home.
  3. What is the difference between a gas and an electric water heater, you may wonder.
  4. The electric variant, as the name implies, is powered by electricity.

If you have no hot water in your house, switch off the water heater first.After that, you should reset the circuit breaker.The hot water will be restored to your house after approximately an hour if the breaker was tripped.Circuit breakers that continue to trip are a negative indicator, so press the reset button to clear the circuit.If the problem persists, you should consult with a certified electrician.

4. Failing Gas Valve

  1. If you have a gas water heater and are experiencing no hot water, you should check the supply line to the device.
  2. Take a look at the gas valve to make sure there are no leaks.
  3. It must be kept safe and in the proper location at all times.
  4. After that, double-check to make sure the gas is turned on.

If the gas valve appears to be in fine working order, check the pilot light.It is possible that you will have to re-light the pilot multiple times.It is essential that it remains illuminated.If it does not, it is possible that the gas line is the source of the problem since it is interfering with the gas supply.When none of these measures results in hot water within an hour, it may be time to invest in a new water heater that is more energy efficient.To be certain, consult with a specialist.

Keep in mind that there are other expenditures to consider when upgrading your water heater, and that the majority of homeowners select between a regular and a tankless water heater when replacing their water heater.

5. Malfunctioning Thermostat

  1. If you want your water heater to generate hot water while still being energy efficient, the thermostat should be set anywhere between 122 and 140 degrees Fahrenheit.
  2. Check the higher thermostat if there is no hot water, if the supply is insufficient, or if the water is too hot.
  3. If the thermostat is no longer functional, it should be changed immediately.
  4. Because of silt building, even if the thermostat is operational, a lack of regular maintenance might result in problems even if the thermostat is operational.

This can be resolved by flushing your water heater.

6. Tank Size

  1. The inefficiency of your household’s energy usage and the rapid depletion of hot water will result if your tank is too small.
  2. Perhaps the appliance performed admirably when it was just you and your husband in the house.
  3. As your family increased, however, so did the need for hot water, which resulted in a significant increase in the number of hot showers.
  4. This indicates that it is time to upgrade to a bigger hot water tank.

When replacing your water heater, keep in mind that electric water heaters take longer to heat than gas water heaters.

7. The Weather

  1. The temperature of the surrounding air impacts how rapidly water may be heated.
  2. The energy efficiency and effectiveness of water heater tanks can deteriorate in the winter, even in temperate climates such as the Southwest.
  3. If you reside in a location where there are frequent cold snaps, this might have an effect on your system and cause water issues.
  4. It’s possible that you’ll have to wait through the cold before insulating the appliance.

8. Recommended Tools and Materials

Water heater not working? If you have no hot water for your shower, washing machine, or dishwasher, follow these troubleshooting tips to restore the heat as quickly as possible.


Q: Even though my shower was perfectly toasty when I hopped in, it quickly chilled until there was no hot water left at all—even an hour later. What gives?

  • The problem of having no hot water in the house is most likely caused by a faulty water heater, assuming that no one else has been using it all day and that you have no hot water in the house but have cold water elsewhere in the house.
  • First and foremost, make sure that your water heater is the proper size for your daily family requirements.
  • Units in this category are available in sizes ranging from around 30 to 80 gallons, with the lower end of the spectrum being perfect for the modest demands of a single-person, half-house arrangement and the bigger end being excellent for families with numerous children.
  • Assuming that your water heater is large enough to meet the demands of your household, how you go in troubleshooting your water heater not heating will be determined by whether you have a gas or an electric water heater in your home.

First things first…

Bump up the thermostat.

  • When it comes to hot water heaters, the ideal working temperatures are between 122 and 140 degrees Fahrenheit.
  • A system operating outside of this range risks not only a lack of hot water, but also the growth of Legionella bacteria, which are responsible for a severe type of pneumonia known as Legionnaires’ disease, if the system is not properly maintained.
  • If your water heater isn’t already set to the optimum temperature range, make the necessary adjustments.
  • You should anticipate hot water to return in 30 to 40 minutes, and the unit should achieve a temperature that will inhibit the growth of germs within two hours after turning on the water heater.
  • istockphoto.com

Check the forecast.

  • A sudden cold snap in your location can have a negative influence on the efficiency of your gas or electric water heater, and it may even cause it to fail completely.
  • This is particularly common throughout the night, when the heater is left unattended and temperatures plummet dramatically.
  • The hot water heater should be turned up to its maximum setting if your recent weather has been consistent with this situation and your boiler is still operating.
  • Try turning on a kitchen or bathroom faucet for a few minutes after half an hour to observe whether the water heats up after it has been running.
  • If it does begin to warm up, lower the hot water heater’s temperature setting to its regular working temperature, or even increase it a few degrees higher than normal until the cold snap has passed, whichever comes first.

If yours is a gas-powered water heater…

Relight the pilot light.

  • Whether it was a downdraft in a vent pipe on a stormy day or the breeze from an open window, you should be able to relight your gas water heater’s pilot light with relative simplicity if you follow the instructions permanently adhered to the exterior of your device.
  • In other cases, such as when the pilot light of a water heater is located within an enclosed burner chamber, you may need to call a plumber for assistance.
  • For those who smell gas while trying to figure out what’s wrong, they should immediately leave the house and contact their local gas provider.

Fix a faulty thermocouple.

  • Even if you can successfully ignite the pilot light and maintain a steady flame after releasing the control knob, it’s possible that the thermocouple—a safety mechanism that shuts off gas flow if it detects that the pilot light is out—is the source of the problem.
  • The tip of this copper tube should be directly above the flame of the pilot light; if it is not, it may need to be adjusted or replaced.
  • Fortunately, a thermocouple is not prohibitively expensive, and changing it is a simple do-it-yourself project.

Rekindle a blue flame.

  • Is your water not quite as cold as it appears to be, but rather lukewarm?
  • Do you have a pilot light that burns yellow rather than the traditional blue?
  • These are the signs and symptoms of a problem with the gas-to-air ratio.
  • First and foremost, be aware that a yellow flame might indicate that the boiler is emitting carbon monoxide, which is a colorless, odorless, and deadly chemical that can cause death.
  • Check for drafts or open windows that might be causing the pilot light to burn inefficiently, and if you find any, fix the draft or open window problem.
  • If this does not bring the pilot back to a crisp, blue flame, contact a specialist to inspect the equipment for further assistance.
  1. As a precaution, keep an eye out for any indicators of carbon monoxide poisoning (such as dizziness, faintness, or nausea), and if required, leave the house immediately to seek medical help.
  2. istockphoto.com

Inspect the gas line.

  • If, after turning on the valve, you do not see a pilot light or smell gas, it is possible that the fault is with the fuel supply itself.
  • Observe to see if the gas valve is open or closed, and look closely at the gas line for any kinks that might be creating an obstruction in the road.
  • After adjusting the gas flow, if the problem persists, contact the gas provider to confirm that service is available in your region and that your account is not in arrears with your payments.
  • Even though the gas company confirms that you should have gas, if you turn the valve on and there is no gas coming out (you would smell it if there is gas), it is likely that you should contact a plumber or other specialist.

If your water heater runs on electricity…

Restart your water heater.

  • When a power surge occurs as a result of an electrical storm, a current might become erratic.
  • To test this, try shutting off your electric unit for a couple of minutes and then turning it back on.
  • If the hot water is still not functioning after half an hour, you’ll need to find another remedy to the problem.
  • Precautions should be taken: Make sure the water heater is turned off before attempting any repairs or even doing an inspection.
  • Because these machines take so much electricity, an accidental electrocution might be devastating, so proceed with caution or seek professional assistance.

Reset the circuit breaker.

  • If the water heater’s dedicated breaker is tripped, it may not appear to be ″off,″ but it may still be slightly out of sync with the other ″on″ breakers, causing the water heater to look to be ″off.″ Then turn it off, wait for 20 seconds, then turn it back on again.
  • A circuit breaker that does not remain in the ″on″ position may have failed due to age or overuse of the circuit.
  • If this is the case, you should seek the services of a professional to replace it.
