How to Test a Hot Water Heater Element
Article to be downloaded article to be downloaded Hot water heaters are essential household appliances because they heat water for use in sinks, dishwashers, washing machines, and showers, among other things.If the water in your house doesn’t heat up to anything more than a tepid degree, experiment with increasing the heat.However, if this does not resolve your problem, it is probable that one of the water heater’s heating components is defective or damaged.Before changing the heater elements, it is necessary to test them using a multimeter, which is a compact instrument that measures the electrical current flowing through metal.
1 Disconnect the circuit breaker that supplies electricity to the hot water heater.While you’re testing the element, the hot water heater must not be in use (must not be receiving electrical power).The electric breaker is a metal box that is around 1 ft 2 ft (30 cm 61 cm) in size and is mounted to a wall.Try looking for it in your home’s basement, laundry room, or huge storage closet, for example.
To turn off the hot water heater, locate the breaker that is labeled ″hot water heater″ or that controls electricity to the room where the heater is located and flick it ″off.″ Remove power from all of the double breakers if you are unsure which one controls the water heater’s electricity (sets of 2 breakers linked together).
2 Remove the metal cover from the water heater so that you can view the thermostat.There will be a metal plate near the base of the hot water heater that you will need to remove.Remove the screws that hold the metal plate in place with a Philips head screwdriver and set them aside.The thermostat and heating components of the water heater may be found beneath the plate on the water heater.
Place the metal cover and screws in a convenient location.You can put the screws in a small bowl if you are afraid that they will roll beneath an appliance.

- 3 If your heater is equipped with insulation and a plastic cover, remove them. Many hot water heaters feature a layer of fiberglass or cellulose insulation behind the metal cover, which helps to keep the water warm. Take that out of the bag and put it away. Many heaters also feature a plastic cover over the thermostat to protect it from damage. This type of plastic cover is held in place by friction, and it usually has a tab on the top that you may pull to remove it from its position. Pulling up on the tab will release the plastic cover, which can then be pulled away from the thermostat. Not all water heaters are equipped with a protective cover made of plastic and insulation. If yours does not, proceed to the next step.
- 4 Check the power using a non-contact voltage detector to ensure that it is turned off. Before you begin working on the hot water heater, double-check that the electric power in the room where the heater is located is turned off and unplugged. To check whether electrical current is flowing to the water heater, place the tip of a voltage detector on the wires heading into the thermostat. If the detector illuminates or beeps, this indicates that the outlet is operational. If the detector does not illuminate, this indicates that you have properly shut off the electricity. A non-contact voltage detector can be purchased at any hardware or home improvement store if you do not already have one.
- The gadget is approximately 5 inches (13 cm) in length and has the appearance of a giant plastic pen. It comes to a climax with a metal prong at the end
5 Identify the ends of the two metal parts that are located inside the open panel on the right.Because they extend several inches into the hot water heater’s interior, the elements themselves are difficult to see.If you peek inside the open panel, though, you’ll notice that the base ends of the two metal parts have been exposed.Each metal base is approximately 1 inch (2.5 cm) in diameter and has a little plastic plate fitted into the center of it.
The vast majority of hot water heaters for houses are equipped with two heating components.Depending on whether you live in an apartment or a small house, you may just have one heating element in your hot water heater.
- 1 Set the ohms of resistance setting on your multimeter to the lowest possible value. A multimeter is a gadget that is used to measure electrical current and voltage. It will tell you whether or not current can flow through the elements of your water heater. Multimeters feature a plastic body that is 2 in x 4 in (5.1 cm x 10.2 cm) in size and two metal prongs that are joined to the body of the multimeter via wires. Multimeters are used to measure voltage and current. You should be able to see a dial on the body of the multimeter that regulates the amount of voltage the gadget is working at. Set the ohms meter to the lowest possible level. It is possible that various models have different lowest settings. Check if the tool is operational by tapping the two metal prongs. The gadget should be calibrated by holding the prongs together and moving the needle until it points to ″0.″
- If you don’t already have a multimeter, you can pick one up at a local hardware or home improvement store for a reasonable price.
- 2 Disconnect one of the cables from the water heater element. Electricity is provided by two wires that travel from each element of a hot water heater to screws that secure the element to the heater’s base. Select the heating element that you’d want to put through its paces first. Remove 1 wire (it doesn’t matter which one) by unraveling it from around the metal element by locating its loose end and unwinding it from around it. It is vital to do this in order to ensure that you are just evaluating the conductivity of the element itself and not any other connected portions of the water heater element
- otherwise, the results will be inaccurate.
- The removal of the wire, which may be difficult if it is firmly wrapped around the water-heating element, may necessitate the use of a pair of needle-nose pliers.
3 To check for flow, place the prongs of the multimeter against the element screws.Placing the multimeter’s body on the ground at the foot of the water heater is recommended.Set the tip of one prong in the center of one of the screws holding the water heater element in place.In the same way, take the second prong and place it in the middle of the second screw on the water heater element’s second screw.
No danger of electrocution exists since you have switched off the electricity to the hot water heater.
4 Check the resistance reading on the multimeter to see how many ohms it reads.In both digital and analog multimeters, there should be a dial or a digital panel that depicts the amount of resistance being measured.A well functioning element will provide resistance readings between 10 and 30 ohms on a micrometer, indicating that the element is functioning properly.If the needle does not move (or if the digital display reads ″0″), the water heater element is not functioning properly and must be replaced immediately.
Even if the digital multimeter displays a very low value (for example, ″1″), this indicates that the element is not functioning properly.
5 If the first water heater element is not functioning properly, test the second water heater element.If you have tested the first element and it appears to be functioning properly, you should attempt testing the second element with the multimeter.It’s possible that this is the problematic component.Identifying which of the pieces is faulty allows you to replace it quickly and easily.
Alternatively, you may call the water heater’s manufacturer and ask if they will be able to send a repair service to your location.
6 Reattach the wire to the water heater and cover the exposed panel on the back.As soon as you’re through testing or replacing the components, use your needle-nose pliers to tighten the wire that you removed back around the screw that it was originally attached to.Snap the plastic cover over the thermostat back into place, then gently push the insulation into place around the thermostat to complete the installation.Replace the metal panel in its original location and reinstall the screws that were previously removed.
Tighten the screws in their holes until the metal panel is securely fastened to the wall or other surface.Final step: Reset the circuit breaker so that electricity may again flow through the circuit to the room where your hot water heater is installed.

7 Steps to Test Water Heater Thermostat
It is possible that you may detect two thermostats on your electric water heater when you inspect it: one at the top and one at the bottom.Each of these devices regulates the temperature of two separate heating components.If you switch on the hot water faucet and only cold water comes out, this indicates that the higher thermostat has failed.However, if the water is hot at first and subsequently gets chilly, this indicates that the lower thermostat has been destroyed.
You will, however, need to understand how to test a water heater thermostat in order to identify the defective device.You’ll be able to correct the situation as soon as you finish this activity.Regardless of whether you have a propane tankless water heater or any other type, the thermostat is an excellent tool for controlling the temperature.But first, let us have a look at how a thermostat operates.
How Does A Thermostat Work?
In most cases, an electric water heater has three primary characteristics.It is equipped with an electric heat source as well as a temperature control system and a switch to protect the device from excessive heat.A thermostat may be used to create hot water that can be used for a variety of applications.Consider that the degree of heat necessary for washing may differ from the level of heat required for bathing, for example: Furthermore, it regulates the amount of electricity that flows to another thermostat or heating element, among other things.
An electric heater with a storage tank of at least 30 gallons is equipped with two heating components, each of which has a thermostat on the other end.The primary thermostat is located on the top of the unit, which also has a high limit switch.The bottom one, on the other hand, is sensitive to any change in the temperature of the water.Both thermostats (which are installed on the same water heater) do not have the same set of capabilities.They even don’t work at the same time as one another.On the same wall as the top thermostat, you will find the high limit switch.
- It also features a button that prevents it from operating, particularly when the water temperature exceeds 170 degrees Fahrenheit.
- This button can be used to reset the system to its default settings.
- To set the thermostat on a water heater, you must first adjust the thermostats on both the water heater and the furnace to equivalent temperatures.
- Alternatively, you may set the upper element to a lower temperature, letting the bottom element to operate first, so saving energy.
- Temperature regulation is handled by a single thermostat and heating element in water heaters with smaller tanks (up to a maximum of 30 gallons).
- They do, however, have a high limit switch, similar to the bigger water heaters.
How to Test Water Heater Thermostat
It is also necessary to examine the heating element on an electric water heater if you wish to test a thermostat on it.This is critical, especially given the fact that open and grounded heating components result in erroneous testing outcomes.You will need to use a screwdriver to inspect the vehicle for problems.As part of the water heater inspection, digital multimeter equipment will be used to assess the temperature of the water heater.
Let’s get started with the procedures that will show you how to test a water heater using a multimeter in the next section.
- Make your way over to the thermostat terminals and check to see whether it is receiving electricity. It is possible that terminals 1 and 3 will show a reading of 240V if this is the case. However, if there is no reading, the power source should be checked. Examine the high limit switch for any signs of current as well.
- By turning the thermostat’s dial to the lowest position, you can disable the lower thermostat. After that, raise the temperature of the top thermostat to check for malfunctions.
- Connect the prongs of the multimeter to the terminal 1 and the blue wire of the heating element to test the voltage. This will assist you in determining whether or not electricity is being delivered between the upper heating element and the blue wire
- if the instrument reads 240V, it indicates that power is being supplied to the setup. After that, connect the prongs of the heating element to terminal 2 and the blue wire of the heating element. However, if there are no readings, this indicates that the thermostat is malfunctioning.
- Reduce the temperature of the heater to a lower setting. Adjust the dial on the top thermostat to the smallest setting possible while setting the dial on the other thermostat to the highest setting possible
- Return to the bottom heating element’s terminal 1 and the red wire that connects to it. Power should be detected by placing a probe on each of them. If the voltage reading is 240V, there is power in the setup
- connect the probes to terminal 2 and the red wire of the bottom heating element
- and test the system. If you are not getting any readings from your thermostat, you will need to replace it.
How to Replace a Faulty Thermostat on an Electric Water Heater
Installing an electric switch to change the thermostat on an electric water heater is as simple as turning on the water heater.Knowing how to test a thermostat allows you to do the necessary repairs without having to empty the storage tank first.In order to avoid any potential mishaps, you must first cut off the power source and check the cables for voltage before proceeding with the work.You will need to adjust both thermostats on your water heater if you want really hot water.
If the problem is caused by a single thermostat, it is advised that you replace the two thermostats because they are quite inexpensive to replace all at once.It is recommended that you replace your present thermostat with a new one from the same manufacturer before making any changes.If you are unable to locate a suitable replacement from the same manufacturer, try for a similar item from another manufacturer.Don’t forget to include a non-contact voltage tester as well as screwdrivers on your shopping list.
Deactivate the Power Supply
Switching off the circuit breaker that is attached to the water heater will turn off the electricity to the water heater.Water heater breakers are typically comprised of two distinct single-pole switches with a combined 30 amp rating.Some versions, on the other hand, have more amps.The panel that covers the thermostat and heating element of your electric water heater should be removed.
It is possible that you may need to use a screwdriver on some versions since the panels are bolted together.Make certain that you remove the insulation from the back of the panel without disturbing the wires in any way.To avoid electrical shocks, make sure there is no current flowing through the thermostat.It is possible to use a non-contact voltage tester at this point to verify the screw terminals and wires for continuity.
Pull out the Faulty Thermostat
Take a photo of the thermostat’s connections.After you have learnt how to test a thermostat, you may use the illustration as a reference.If you are feeling creative, you may also produce a short sketch.Remove the thermostat’s screw terminals by unscrewing both of them.
Then pull each wire on both of them out one at a time.After that, unclip the thermostat from its connection clips and carefully lift it out of the thermostat chamber.To avoid damaging the clips, apply only the bare minimum of force.To avoid damaging the clips, apply only the bare minimum of force.
Set Up the New Thermostat
Insert the new thermostat into the matching clips on the wall.Check to see that it is properly resting on the surface of the storage tank.Connect the circuit wires to the matching screw terminals on both sides of the board.Tighten the screws to secure them in place.
Increase or decrease the temperature setting on your thermostat according to your preferences.A flat blade screwdriver will be required in this situation.It is recommended that you set the temperature to 120 degrees Fahrenheit.
Add Final Touches
Replace the thermostat chamber panel as well as the insulation surrounding it. By resetting the circuit breaker, you may reconnect the circuit to its power supply once more. Allow for two hours of operation from the water heater, then check the hot water tap to verify whether the water is sufficiently heated
How to Troubleshoot a Defective Thermostat on An Electric Water Heater
Troubleshooting the thermostat on your water heater may appear to be a complicated task. This tutorial will assist you in doing this task without the need to consult an expert.
- To turn off the electricity to the thermostat, go to the circuit breaker and turn it off. Because it protects you from electrical shocks, this procedure is really necessary. A two-pole breaker will cause both breakers to trip at the same time if you are working with two breakers.
- Remove the two panels that protect the thermostat from the wall. Insulation that corresponds to the aperture is found beneath the cover. Remove the item and store it aside for later installation.
- The thermostat and heating element should both have a plastic panel on them. A button may be found beneath the panel. It should be pressed to confirm that it is in great working order.
- Keep an eye out for a ″snapping″ motion when you press the button. In the event that you experience any, turn on the power and allow it to run for a few minutes.
- Check to see whether there is no power to the unit, especially if you want to continue working on the equipment. Make use of a non-contact voltage tester to test a pair of wires towards the top of the circuit. If you don’t see any lights or hear any beeps on the meter, this indicates that there is no energy flowing through the thermostat.
- Even if you do not see any readings on the tester, continue to work on the machine as if there were power. Remove the plastic cover from the thermostat by gently pulling it out or unscrewing it. Avoid inserting your fingers too far inside the device in order to avoid potential mishaps.
- Remove the battery and connect it to a voltmeter with a minimum voltage of 240 volts on it. Place the test lead on all of the higher screws. Do not remove the lead. If you get a reading, it means that the power is switched on
- turn it off and check again later. There must be no electricity running through the device.
- An electric water heater, like a tankless water heater, is equipped with a thermostat. Fortunately, just a few equipment are required for testing and repairing a malfunctioning thermostat, including a multimeter and a pair of screwdrivers. To solve this dilemma, you don’t even need to have any special abilities. All you have to do is follow these simple instructions. Turn off the electricity
- When you test the device, make sure there are no difficulties. If there are, remove the present thermostat and replace it. In order to avoid any shocks while working, it is recommended that you periodically check the equipment for any current.

Checking Water Heater Vent Draft
- The vent draft of a water heater should be checked regularly for safety reasons.
- Carbon monoxide is present in the fumes from a hot water heater, and it can make you ill or even make you lethal at certain concentrations.
- Making certain that the water heater is correctly vented might provide you with some piece of mind.
- The effectiveness of the water heater is also taken into consideration.
- Not sure if it’s the vent or anything else?
- See the article ‘Troubleshooting a Gas Water Heater’ for a comprehensive list of all of the gas water heater topics discussed here.
The information provided below explains how to determine whether or not the water heater vent is functioning properly.A section is devoted to providing instructions on how to properly install the vent.If anything isn’t operating well or isn’t installed correctly, you’ll want to have it fixed as soon as possible.
How a Water Heater Vent Works
- Your hot water tank’s burner is located at the bottom of the tank.
- The burner burns by drawing in air from the surrounding area.
- Grilles must be built in a tiny space in order to allow for adequate air movement to occur.
- Once the gas has been burnt, it is vented up through the middle of the tank and out the flue at the top of the tank.
- If the chimney is suitably sized, it will generate a draft that will draw the vapors up and out into the surrounding environment.
- An air gap surrounding the fume hood allows the hot combustion gases to draw air, which is beneficial for both of them.
The fume hood is supported by small pieces of metal that are inserted into slots on the top of the water heater to provide stability.WARNING!When a water heater is improperly vented, it may be quite dangerous.WARNING: Turn off the gas to your water heater immediately!
Checking the Vent Draft
Setting Up the Test
- As a general rule, you should test the vent airflow in the most adverse conditions possible.
- Essentially this implies that the water heater should still vent correctly even when there are other ventilating equipment operating, such as a bathroom exhaust fan, and there are no open windows.
- First and foremost, you must close all of the windows and doors in the house in order to adequately test the vent draft.
- If you have a fireplace, you should also close the damper on it if you have one.
- Exhaust fans in the bathroom and kitchen should be turned on at this point as well.
- In addition, the dryer should be running.
This may appear to be severe, but it accurately simulates the conditions that exist when everything is in use at the same time.Reduce the temperature of the furnace so that it does not run while you are doing the test.Run a sufficient amount of hot water to start the water heater’s burner.Before you begin the test, let the burner to run for a few minutes before you begin.
Performing a Low Tech Draft Test
- Several minutes after turning on the burner, you should be able to feel air being drawn into the fume hood from the outside.
- Place your hand near the vent hood, but do not contact it with it.
- Hold your hand in a sideways position with a small cup.
- If you can feel air pushing out of the fume hood, then means it’s not working properly.
- See below for more information on what is known as a ″down draft″ or a ″back draft″ and how it can be dangerous.
- With your hand, you should be able to feel the air being drawn into the vent hood, indicating that it is working properly.
If you are unable to feel any air being drawn in or if you feel air being pushed back, you have a draft problem.Another low-tech way to check for drafts is to hold a match or lighter near the fume hood while it is running.Before performing this test, make sure that the water heater burner has been running for several minutes.The airflow should be strong enough to bring the flame into the hood of the stove.If the flame sputters or goes out, this could be a sign that something is wrong.
- The presence of soot around the fittings is another thing to check for.
- Any evidence of black soot indicates that the smoke is not being expelled by the chimney.
- If there is any indication that the vent is not functioning correctly, you will need to take steps to repair the situation.
- For information on how to clear blockages from water heater vents and chimney flues, see the articles ‘Fixing Blocked Water Heater Vents’ and ‘Unblocking Chimney Flues’, respectively.
Back Draft – What It Means
- A back draft, as the name indicates, is when air is pushed back into the room where the water heater is located, rather than into the chimney as is normally the case with forced air.
- This is a potentially hazardous situation since the exhaust from the water heater includes potentially hazardous gases.
- Try turning off one or more of the fans and/or opening a window to see if the draft improves if the above-mentioned test fails and you have verified that there is no obstruction.
- Depending on whether this is the case, you may need to give some ″make up″ air for the water heater.
- A duct that brings in fresh air from the outside is typically used for this purpose.
- When the water heater need extra air, the duct will be there to supply it.
The installation of this sort of ducting is outside the scope of this article, therefore please refer to it for further information.If you want to learn more about water heater backdrafting, there are two sites that you may look at: ″Water Heater BackDrafting – Part 1″ and ″Water Heater BackDrafting – Part 2.″
Checking the Vent Installation
- The fume hood should be placed at the same level as the tank.
- Each of the vertical legs should be straight and fit into the slots that have been given.
- Place the fume hood directly over the circular aperture at the top of the hot water heater.
- If it is crooked or skewed to one side, it should be straightened immediately.
- The vent should be slanted upward, toward the entrance in the chimey, to provide proper ventilation.
- It is recommended that the vent be pitched upward at a rate of at least 1/4″ per foot.
It should not have an elbow that is right over the water heater’s entrance.A horizonal run that is too lengthy is undesirable.The water heater should be installed as near to the chimney as practicable.When a vent is not placed in such a way that it allows for free flow of the exhaust, it will need to be repaired.Reduce, if required, the number and placement of elbows, and check that the ducts are pitched appropriately before installing them.
When it comes to carbon monoxide, considerable attention should be exercised to ensure that it is properly evacuated from the hot water heater. Make sure there aren’t any blockages in the way of the oven or chimney flue working.
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.
- To learn more about how to troubleshoot an electric water heater in greater depth, please watch the video below:
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
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
- 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.
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
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.
7 Tell-tale signs of a Water Heater not working
- During the hot summer months, I’m perfectly willing to take a lukewarm shower to keep cool.
- To the point where on a hot and humid day, I would even prefer to be splashed with cold water.
- However, when winter arrives and it’s time to get out the jackets, turn up the heat, sip hot chocolate, and cuddle under the covers, the water heater is generally the unsung hero of the day.
- When the snug layers and hot beverages aren’t enough to keep me warm, a warm shower or bath is the ideal remedy.
- Understanding the early warning indications that your house’s vital system is beginning to fail is a crucial skill to have as a homeowner.
- After all, the sooner you notice problems, the less likely it is that you will be left without a home.
Additionally, keeping up with regular water heater operations around your house will help you avoid costly repairs and replacements down the road.Is your water heater not functioning properly?No need to be concerned – here are seven frequent water heater problems, as well as advice on what to do if you detect any of these warning signals of trouble.
1. You don’t have enough hot water
- Do you have hardly enough hot water to take a single shower every day?
- Do you wash the dishes and realize that you’re doomed if you want to take a warm bath afterward?
- I’ve been there myself: My water heater was inadequate to service all of the units in my apartment building, and I was so anxious for a hot bath that I heated water in my kettle and then poured it into the tepid water in my tub.
- It’s possible that your water heater isn’t producing enough hot water in these situations; nonetheless, you shouldn’t be boiling water in a kettle on your stove since it’s potentially unsafe.
- Increasing the temperature dial on your water heater to a higher setting, waiting around 30 minutes, and then monitoring the water temperature at a faucet, as recommended by HomeTips, is a quick and simple solution.
- Make verify that the circuit breaker is still in the ″on″ position and that the associated switch is still in the ″on″ position, as this might have caused the thermostat to become stuck on a different setting.
- A specialist should be contacted right away if you have an electric water heater that is constantly tripping the circuit breaker.
- This indicates that the machine is consuming more power than it requires, which is most likely due to wiring issues or poor electrical connections.
- If it doesn’t make a difference, try draining the water tank to eliminate sediment and increase the efficiency of the machine.
- A malfunctioning component, such as a temperature-pressure relief valve, heating element, or dip tube, might possibly be the source of the problem.
Consider having a professional plumber check the pipes to determine the source of the problem and repair the necessary parts.This depends on your level of DIY plumbing skills.Important note: If you consistently feel as if you don’t have enough hot water rather than experiencing a recent lapse in supply, your water heater may be too small for your needs and needs to be replaced.As a result, you might want to think about upgrading to a newer unit with a larger tank or investing in a tankless, on-demand unit.
2. You have varying water temperature issues
The water might be too hot for one second, too chilly for the next, and occasionally exactly perfect in between. The fact that your water temperature is fluctuating is easy to overlook, but it might be an indication of a far larger problem with your water heater that will only worsen with time.
- Check to verify that your water heater’s thermostat is adjusted to the temperature you wish.
- Consider lowering the thermostat to a cooler setting if you notice the water is too hot to the touch, for example.
- HomeTips offers some sound advice: Before making any adjustments, make a mark on the current setting with tape or a marker.
- If the thermostat changes on its own, you will be able to detect it.
- According to Sears, if the water is constantly too hot or too cold even when the thermostat is set to the proper temperature, you may need to replace the thermostat or the heating element in your water heater, among other things.
- The Spruce supplied examples of such conditions, such as showers that are continuously lukewarm, which indicates that the higher heating element is faulty.
A problem with the bottom element is likely to be the cause of your shower running out of hot water too rapidly.When it comes to internal components such as these heating elements, it is best to seek the assistance of an expert who can either repair or replace the damaged element.Another crucial point to mention about unit size is as follows: According to the Spruce, a 40-gallon heater, for example, is intended to meet a demand of around 30 gallons per minute.The capacity of the unit may be met by spreading out your water use or by upgrading to a larger water heater, which will eliminate temperature swings.While a 30-gallon capacity is plenty for one person, two persons would most likely require 40 gallons of storage space.
- In the case of a family of three, Lowe’s recommends selecting a model with at least 50 gallons of capacity, and increasing the capacity from there for families with four or more people.
3. You have a leaking water heater
Water pouring from the unit or gathering around the tank’s base is a serious problem that has to be addressed as soon as possible. A leaky water heater is usually an indication of a significant internal problem with the unit.
- When diagnosing a water heater problem of this nature, it is extremely vital to be cautious.
- SF Gate Home Guides recommended that you unplug the electricity or turn off the gas to the unit before attempting to fix the problem.
- This will allow the unit to cool down before proceeding.
- It is possible to check the water heater from there to establish where the leak is coming from.
- Starting with the unit itself, ensure sure all of the inlets, fasteners, connections, and pipes are secure and haven’t fallen free.
- If this is the case, re-tighten them into position.
After that, inspect the unit’s bottom for signs of excessive leaking.Water heater condensation is typical because the temperature-pressure relief valve may be releasing excess or built-up pressure from the unit, which causes the condensation to appear on the unit.A significant leak, on the other hand, indicates that something is wrong and that you should contact an expert for assistance.If the tank is leaking, it’s probable that the expert will propose that you replace the water heater completely with a new one.
4. You notice reduced water flow
It is possible that a build-up of scale or silt in your water heater, or within the tubing that links the unit to various places throughout your home, is causing the changes in flow rate or pressure. This is not a warning sign that should be ignored and dealt with later, since the accumulation will only worsen and may result in you being without much-needed hot water in the heart of winter.
- If you do not have a tankless water heater, you can drain the tank and clean away the sediment by following the methods outlined below.
- As part of this process, you’ll want to examine your pipes and address any drainage concerns that may be influencing the water’s flow pressure.
- You can, however, make an appointment with a professional to descale your water heater and clean the intake and outlet pipes in order to cure the problem.
5. You’re hearing some concerning sounds
- Listen for any strange sounds coming from your water tank, such as loud cracks or pops, whining or banging, gurgling or boiling.
- If you hear any of these, call your local plumber.
- If your unit makes any of these noises, it is attempting to communicate with you that something is amiss.
- Noises originating from a water heater tank are often caused by either burning sediment and scale or a decaying heating element, according to DoItYourself.com.
- Boiling noises are by far the most concerning, since they are typically indicative of severe overheating or pressure building in the system.
- Like other frequent water heater problems, the first line of defense will be to drain the tank and remove any residue that has accumulated.
- If the sounds persist even after you have flushed away the burning buildup, it is probable that you will need to repair the heating components.
- If, on the other hand, you hear the boiling sounds described above, don’t waste time attempting to resolve the problem yourself.
- Rather, contact a professional for quick assistance.
6. You have smelly or discolored water
Strange water scents, such as those suggestive of rotten eggs, or discoloration, such as rusty or muddy colors, may indicate the presence of bacteria or rust inside the water heater’s tank, which should be addressed immediately. Furthermore, the anode rod in the tank, which is responsible for killing germs and removing rust from the water, may be damaged.
- In order to identify whether the foul odor and discoloration are caused by a problem with the source water or the heater itself, the first step is to conduct a test. To do so, turn on a faucet and run both cold and hot water through it. Check your findings against the following professional advice from HomeTips: The following odor and discoloration can be seen in both hot and cold water: Problem with the water supply at the source
- Only cold water is available due to a source–water issue.
- There is just hot water because of a water heater problem.
- The installation of water filters and softeners to remove iron, copper, and other minerals from the water before it reaches your faucets is the best answer if you have a source–water problem on your hands.
- Iron, copper, and other minerals are removed from the water before it reaches your faucets.
- Hot water scents and discolouration, on the other hand, necessitate the cleansing of your water tank.
- Sears recommended draining the tank, filling it with 32 ounces of bleach, then flushing it again to eradicate odor-causing germs and remove rust, according to the manufacturer.
- Another option is to raise the temperature to 160 degrees for an hour or so before cooking.
- Draining the tank and running hot water for a few minutes should reveal whether or not the strange smell and colors have disappeared.
If this is not the case, you will need to replace the anode rod.Due to the fact that this demands a significant amount of plumbing skills and experience, many homeowners may seek professional assistance in order to finish the replacement process.It has also been reported that if you have a gas water heater, you may smell a garlic-like stench emanating from your water when the pilot light is turned off, according to HomeTips.Before re-lighting the pilot, switch off the gas valve control and wait for the gas smell to dissipate before turning it back on again.If the gas smell persists, contact a professional for assistance.
7. Your water heater is on the older end of the spectrum
- A five-year-old water heater is significantly less durable and dependable than a modern water heater constructed just five years ago.
- If you have recently acquired a new water heater, you may anticipate it to operate quietly, efficiently, and mostly without maintenance for at least 10 years at a time.
- Older machines, on the other hand, can hum, pop, and clang while producing disappointingly tepid water as they near the end of their useful life.
- If the age of your water heater is in the double digits – and especially if it is exhibiting any of the warning signals listed above – it may be time to upgrade to a modern model.
- Not only will your showers be more relaxing, but you may also see a reduction in your monthly expenditures.

- Insulating the unit and hot water pipes can also help to improve efficiency by minimizing energy loss and overworking of the system.
- When doing maintenance on your water heater, remember to use gloves and goggles to keep your hands and eyes safe.
To be safe, you should always switch off the electricity to the heater’s circuit before completing any chores.Preventative maintenance should be performed on your unit long before the winter season begins, whether you arrange an appointment with a licensed expert or complete the duties yourself.During the winter months, scheduling expert inspections and repairs is more difficult, and the costs may be greater as a result of the reduced demand.Preparing for water heater problems before they occur is usually a wise tactic to employ.See how HomeServe’s TotalHome Warranty by HomeServe can assist you in reducing the costs of covered appliance and home system repairs.
How to Diagnose a Water Heater Problem
In the event that our water heater is functioning well, we utilize hot water for everything from showers to laundry without giving it a second thought. However, if it ceases to function, we must identify the cause of the problem and repair it. What is the best way to identify a water heater problem?
- If there is just no hot water, it is possible that the pilot light has been extinguished. Make that the pilot light is working properly. Alternatively, if it is out, you may relight it by following the instructions in your owner’s handbook. If you are unable to complete this task alone, a professional from the gas company can assist you.
- You may be hearing minerals or hard-water scale that has collected inside the tank and has broken off, if you are hearing weird noises coming from the hot water heater. This means you’ll have to drain the tank and clear up the sediment in this situation. It’s possible that you’ll want to hire a professional for this work.
- If you notice water on the floor near the water heater, it is likely that water is leaking from the tank into the house. It is possible that the water is coming from a faulty valve or a leaking pipe. It’s possible that you don’t have any leaky pipes, therefore you may try tightening the valve. If this valve is not properly secured, water may flow from the heater. Other than that, the leak might be the result of a malfunctioning valve, an obstruction in the venting system, or a damaged heating element.
- The first thing to do if the water isn’t hot enough is to check the temperature of the water. Check to see whether the thermostat is set appropriately and attempt to recall the last time you flushed the tank. Mineral buildup inside the tank might prevent the water from heating up correctly, causing it to boil. However, if your tank does not require flushing, you may wish to inspect the dip tube of your heater. It is impossible for the water to heat up adequately if the dip tube is damaged. It is possible to inspect the dip tube by disconnection of the cold water supply line and removal of the dip tube from the tank.
