How to Tell If the Hot Water Heater Is on
Heaters are necessary because they heat water that is used for a variety of purposes, including cooking, washing clothes and bathing. You probably don’t give your hot water heater much thought until you’re in the middle of taking a shower and there is no hot water available. There are a variety of factors that might contribute to your water not being hot, so you should check to see if your hot water heater is turned on. Take a look at the methods listed below to assess whether or not your hot water heater is operational.
Check the Breaker in the Electricity Panel
You should check your circuit breaker first if you are experiencing problems with hot water when you ask for it. This is normally found in the garage or the basement, and it will be clearly labeled with the breaker settings. You should double-check that the hot water heater is operational. It will be protected by a circuit breaker that is specifically designed for it. If you aren’t sure which circuit breaker controls your hot water heater, but you notice that one has been tripped, you can try switching it to see if it fixes the problem.
If this is the case, you will almost certainly need to hire a specialist to make the necessary repairs.
Check the Pilot Light on a Gas Hot Water Heater
Electric hot water heaters are powered by electricity, whilst gas hot water heaters are powered by a natural gas connection. You will be able to identify whether or not the hot water heater is operational by the pilot light. Take a look at your machine and make sure that the pilot light is illuminated before continuing. If it is located near a window or outside, it may be snuffed out by a prevailing wind. If the pilot light is out, there will be instructions on how to switch it back on near the pilot light.
Check the Switch on an Electric Hot Water Heater
Electric hot water heaters are frequently equipped with a switch that allows them to be turned on and off. If you’re not sure if it’s on or not, look at the switch. On most models, this switch is positioned near the hot water heater, and you should be able to quickly turn it on or off. The switch has the same appearance as any other wall switch. Even if the switch is turned on, you have the option to turn it off. Locate a reset button on the hot water heater tank and press it to restart the system.
- In addition, it is crucial to know that the majority of hot water heaters operate at 240 volts, which is more than enough to electrocute someone.
- If you turn on the switch and everything works, it is fantastic.
- Hot water heater repair is a complex task, and if you don’t have any prior knowledge, you may want to consult with a professional.
- Because they consume so much power, hot water heaters are quite dangerous if anything isn’t operating properly.
- Most hot water heaters have a lifespan of roughly ten years, so if you are towards the end of your hot water heater’s useful life, you may want to consider replacing it immediately.
- These items will provide you with the information you require.
Due to the large number of diverse options available, you would benefit from the guidance of an experienced professional. Always take caution while working with large appliances since, if something goes wrong, they can cause serious injury or death.
DIY Water Heater Testing and Repair
Occasionally, the heating elements on electric water heaters break long before the water heater itself fails, but changing them in a hot water heater is a simple Do It Yourself repair.
Tools Required
The majority of the time, replacing one or both of the heating elements will address the problem if your electric hot water heater is taking a long time to heat up, running out of hot water more quickly than it used to, or not delivering any hot water. Water heater repairs are simple, and replacement components are affordable ($8 to $20), and they are easily accessible at home centers, hardware shops, and appliance parts dealers across the country. How to test the heating elements, remove one if it’s defective, and replace it with a new one will be demonstrated.
If your heater is reaching its end of life, it may be more cost-effective to replace it than to repair it.
Other Causes of Water Not Getting Hot
Of course, there are a variety of additional factors that might contribute to a shortage of hot water. Before you begin testing the elements, double-check that the circuit breaker is not tripped and that it is in the on position. Press the reset button on the high-temperature cutoff, which is positioned slightly above the top thermostat, at the same time. Although resetting either the circuit breaker or the high-temperature cutoff may remedy the problem, the fact that they were tripped in the first place may suggest that there is an electrical fault with the system in the first place.
Assuming that the heating components are working properly, the thermostats or cutoff switch may be defective.
Video: How to Test Your Water Heater Element
- Power should be turned off at the circuit breaker. Remove the metal covers from the thermostats and heating components to reveal them.
- Pro tip: Check that the power has been turned off by tapping the electrical connections with a noncontact voltage detector.
Test the Wires
- Please keep in mind that if the wires are covered by metal conduit, the tester will not read the voltage. Take off the metal thermostat cover that is mounted on the side of the water heater, peel out all of the insulation, and place the tester in close proximity to the wires that go up to the top of the high-temperature cutoff switch.
- Placing the tester against the metal water heater shell will get the following results:
- Note: If the tester does not light up, it is okay to proceed with the testing of the components.
What’s Inside a Water Heater and How It Works
The vast majority of domestic electric water heaters feature two heating elements: one near the top of the tank and another towards the bottom of the tank. After entering the top, power travels to the high-temperature cutoff switch, and then to the thermostats and elements on each side of the unit. The temperature of the top and bottom components is regulated by two different thermostats. When the water at the top of the tank becomes too hot, the top element goes off and the bottom element takes over to heat the water.

Test Continuity for a Burned-Out Element
- Please keep in mind that you will need a continuity tester ($5 to $10) for this stage.
- Disconnect the wires from the terminal screws using a wire cutter. Attach the alligator clamp to one of the element screws using a hex key. With the tester probe, make contact with the other screw.
- Note: If the tester does not illuminate, the element should be replaced.
Test for a Short Circuit
- The alligator clip should be attached to one of the element screws. Touch the tester probe to the mounting bracket for the element
- Repeat the process on the other screw.
- It is important to note that if the tester light illuminates either time, there is a short. Replace the element with a new one
The Secret of the Red Button
Occasionally, both elements will pass the test, but you will still be unable to receive hot water.
Try pressing the “high-temperature cutoff” button, which is situated right above the upper thermostat, to see if that helps. It may temporarily cure the problem, but if the problem recurs, the heating components should be checked. Step number five.
Remove the Bad Element
- Close the intake valve for cold water
- Start by turning on the hot water tap in the kitchen. Pour water into the tank by connecting a garden hose to the drain valve and opening it
- Note: A water heater element wrench (available for $5 at home centers and hardware stores) is required for thread-in–type elements such as those shown below.
- Remove the old heating element by unscrewing it using a heating element wrench.
- Pro tip: To spin the socket, you’ll need a long, robust Phillips screwdriver with a flat blade. To free the threads that have become stuck, use a cold chisel and a hammer to loosen the threads that have become stuck.
Install the New Element
- Insert the replacement element into the water heater and tighten it down with the heating element wrench if necessary. Reconnect the wires, checking to see that the connections are secure. Remove the insulation and metal covers and replace them.
Buying Heating Elements
Replace your heating element with one that has the same wattage as your existing one. For information on wattage if your old element isn’t labeled, look at the nameplate on the water heater, your instruction manual, or search online using the model number found on the nameplate. Heating elements are secured to the water heater with either a big thread and nut, as illustrated below, or with four bolts and nuts, as indicated in the diagram below. Most home centers carry the type we’ve shown, but if you’re replacing the four-bolt version, you may purchase an adaptor kit.
Low-density parts that are more costly are typically folded back.
Replacement of your old element with a low-density element will result in more efficient functioning and a longer service life.
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 components that extend into the water tank heat the water in an electric water heater, which is powered by electricity.
When it comes to electric water heaters that provide little or no heat, the most common problem is a faulty heating element, which is a pretty affordable component that is quite simple to repair.
Watch Now: How to Repair an Electric Water Heater
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.
The following is something that you can perform before you start diagnosing the issue.
Warning
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).
Also, use a non-contact voltage tester to check all of the wires in the water heater to ensure that the power is turned off before touching any of the wires.
How to Fix
Working with electric water heaters when the power is on may be quite dangerous because of the high voltage (240 volts). Shut off the electricity to the water heater’s circuit by turning off the relevant breaker in your home’s service panel before you begin testing any electrical components of the water heater (breaker box). A non-contact voltage tester should be used to check all of the wires in the water heater to ensure that the power is off before touching any of the wires.
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:
- Turn off the circuit breaker for the water heater’s circuit at the service panel if necessary. Removing the access panel for the water heater’s upper heating element is a good idea. 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
- To reset the high-temperature cutoff, press the red button above the higher thermostat, which is positioned above the upper thermostat. Reinstall the safety guard, the insulating material, and the access panel. Turn on the circuit breaker for the heater. Test each heating element and replace it if required if this does not resolve the problem

Inadequate Hot Water
If your water heater is producing hot water but not enough of it, it is possible that your unit is too small to satisfy the hot water demands of your home. Take precautions to ensure that the water heater’s capacity does not exceed the demand.
How to Fix
The water heater should be able to provide hot water to a capacity of 75% of its total capacity. For example, a 40-gallon water heater is appropriately suited for a 30-gallon demand. If the demand exceeds the capacity of the heater, attempt to restrict the length of showers, install low-flow showerheads, and spread out dishwashing and laundry to different times of the day rather than doing them all at the same time to reduce the strain on the heater. The failure of one or both of your unit’s heating elements, even if your unit is not undersized, might indicate that one or both of its heating elements have failed.
When 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
Ideally, 75 percent of the total capacity of the water heater should be used to heat the water. For example, a 40-gallon water heater is appropriately designed for a demand of 30 gallons per minute. 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 system. 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 gone bad.
While showering, you may see a steady flow of warm water, which indicates that the upper heating element is malfunctioning. It is possible that the bottom heating element is faulty if the hot water runs out rapidly when you are in the shower. Getty Images / Glow Decoration
How to Fix
To double-check the thermostat settings, do the following:
- In the service panel, turn off the electricity to the water heater to conserve energy. 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. Using a non-contact voltage tester, check the cables to ensure that the power has been turned off. 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. Make use of a flathead screwdriver to adjust the temperature to the correct level
- And Set the other thermostat to the same temperature as the first
- For each element, replace the safety guard, insulation, and access panel as needed. 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, which is why it is critical to repair the leak as soon as it is discovered.
How to Fix
Leaking valves and plumbing connections are the most common causes of water leaks, although they can also be caused by issues with the tank. In order to prevent serious damage to a property, it is critical to repair any leaks as soon as they are discovered.
Rust-Colored Water or Bad Odor
Water leaks are often caused by leaking valves and plumbing connections, but they can also be caused by issues with the tank itself. Water leaking into a property may cause substantial damage, therefore it is critical to repair the leak as quickly as possible.
Tank Making Noises
Is your water heater making noises? If so, what are they? Is there a low rumbling or popping sound when you turn it on? What if it’s a high-pitched whine instead? It’s possible that the sounds you’re hearing is the sound of boiling water. When there is a significant amount of sediment building in the bottom of a tank, it can cause the bottom of the tank to overheat, which can result in the water boiling.
How to Fix
In order to remove the silt from the tank, the first thing to attempt is to empty it. The tank may need to be replaced if this does not alleviate the problem. “The Spruce” is a song by Candace Madonna.
How To Tell If Your Electric Hot Water Heater Is Bad?
There are two techniques to determine whether or not you have a faulty electric water heater. One possibility is that the water heater may cease to provide hot water. The other problem is that the water heater will leak. If your water heater stops heating, it’s possible that you have a power or component problem. A broken water heater construction or a leaky valve or pipe are the most likely causes of water heater leakages. How to identify whether your water heater is in need of repair EXAMPLE: AN ELECTRIC WATER HEATER IS LEAKING WATER: If your electric water heater IS LEAKING WATER, turn off the circuit breaker and investigate the source of the leak.
- Alternatively, if the water leak is coming from the bottom of the water heater, it is possible that the structure of your water heater has decayed or rusted over time, resulting in a structural water leak.
- If your electric water heater is not leaking water but is not providing hot water, follow the steps outlined in the section below.
- Power will be restored to the water heater simply by reconnecting the breaker, if it has been accidentally turned off.
- It is necessary to inspect the water heater itself if no circuit breaker has tripped and no hot water is being produced by the electric water heater.
- The most common reason for an electric water heater to stop providing hot water is a faulty thermostat.
- It’s possible that one of the two heating components in your electric water heater has failed, causing this problem.
- Turn off the circuit breaker that is connected to the electric hot water heater.
3– Check to see that the terminal where the power cables are attached is not melted or fractured; if it is, it should be removed and replaced.
5– Check the heating elements using a multi-meter to ensure that they are in proper operating condition.
NOTE: If you need to repair a heating element or any damaged internal part in your water heater, you must first empty the water heater completely before removing any of the internal components.
The thermostats must be tested with a multi-meter whether the heating components are in excellent working condition.
8– If your water heater is equipped with a safety thermostat, make sure to check that as well.

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.
Additionally, keeping up with regular water heater operations around your house will help you avoid costly repairs and replacements down the road.
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.
Your move:
According to HomeTips, moving the temperature dial on your water heater to a higher setting, waiting around 30 minutes, and then testing the water temperature at a faucet is a simple solution to this problem. 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.
When all else fails, consider emptying the water tank to eliminate sediment and increase the unit’s overall efficiency.
Consider having a professional plumber check the pipes to determine the source of the problem and repair the necessary parts.
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.
Your move:
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. The manufacturer stated that if the water is regularly excessively hot or cold even after the thermostat has been set to the proper temperature, you may need to replace the thermostat or heating element, according to Sears.
A problem with the bottom element is likely to be the cause of your shower running out of hot water too rapidly.
Another key point to notice about unit size is that a 40-gallon heater, for example, is designed to meet a demand of around 30 gallons.
While a 30-gallon capacity is plenty for one person, two persons would most likely require 40 gallons of storage space.
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.
Your move:
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 repair it. 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.
After that, inspect the unit’s bottom for signs of excessive leaking.
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.
Your move:
Even if you don’t have access to a tankless water heater, you may drain and clean your tank by following these procedures. Ensure that your pipes are in proper working order and that any drainage concerns are corrected before continuing. 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. Water heater tank sounds, according to DoItYourself.com, are often caused by either burning silt and scale or a decaying heating element in the tank itself. Boiling noises are by far the most concerning, since they are typically indicative of severe overheating or pressure building in the system.
Your move:
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.
Your move:
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.
Draining the tank and running hot water for a few minutes should reveal whether or not the strange smell and colors have disappeared.
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.
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.
Your move:
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 replace it with a modern model to save money. Not only will your showers be more relaxing, but you may also see a reduction in your monthly expenditures. In the opinion of HouseLogic, modern water heaters can be up to 20 percent more efficient than older, traditional ones, resulting in savings of up to $700 in energy bills over the water heater’s lifespan.
Avoiding issues with regular maintenance
Professional inspections and hot water heater maintenance should be performed on a regular basis. A lot can be done to assist keep the functionality and efficiency of your hot water heater in good working order. For example, by draining out your tank every few months, you may avoid the scale and sediment accumulation that is so frequently the source of hot water difficulties. Aside from that, you’ll want to examine critical components on a regular basis to ensure that they’re in perfect working order.
- Insulating the unit and hot water pipes can also help to improve efficiency by minimizing energy loss and overworking of the system.
- To be safe, you should always switch off the electricity to the heater’s circuit before completing any chores.
- 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.

Becoming aware of potential water heater problems before they occur is always a wise move. See how plans from TotalHome Warranty by HomeServecan assist you in reducing the price of covered appliance and home system repair expenses.
Common mistakes
Shutting down the wrong breaker- Shut down all of the breakers until you are certain which one is responsible for powering the water heater. If your multimeter does not function, you should always test it on an outlet that you are certain is operating properly. With the power on on, remove the assess panels and insulation. The exposed wire is right behind the insulation.
Power off check
Turn off the electricity to the water heater. The upper (top) access panel, the plastic safety cover, and the insulation must all be removed before the work can begin. The thermostat receives power from the wall directly above the reset button. Notice that they are labeled with the numbers 1 and 3 in this photo. When the electricity is turned on, the voltage on each wire is 120 volts. Set the voltage on your meter to 120 volts or higher. In order to acquire a good ground on the water heater tank, you can scrape it with your probe to make a good ground.
You should have a voltage of 0 volts.
In the same manner, check the other terminal.
If you make a mistake, the circuit breaker will be tripped.
Check water heater power for 240 volts
Restore electricity to the system. Set your multimeter to 240 volts or higher alternating current. With the meter probes, make contact with each of the terminals 1, 2, and 3. You should be able to read 240 volts on your meter. If your meter indicates that there is no power, there may still be 120 volts present on one of the terminals, so avoid touching anything. Re-check each terminal in the same manner as you did above, but this time make sure the power is turned on. Each terminal should have a voltage reading of 120 volts.
Notes on the Side In the case of a 120-volt connection with just 240-volts delivered to it, the meter will read zero voltage since there is no ground present.
The voltage measurement on the water heater may fluctuate between 115 and 120 volts and 230 and 240 volts.
How to Troubleshoot Electric Water Heater Problems
In a house full of people, if you’ve ever been the last to shower, you’ll know what’s in store for you before you ever step into the bath: bone-chilling, teeth-chattering ice cold water. If you’re having water troubles, even when there aren’t a lot of people in the house, it’s time to take a closer look at your electric water heater.
Symptoms of an electric water heater malfunction might include low water temperature, leaks, discoloration, odor, and noise, amongst other things. An illustrated procedure to guide you through the process of troubleshooting your water heater problems is provided below.
Before you start: turn off the power
First and first, safety must be prioritized. First and foremost, make sure that the electric water heater is completely turned off before doing any troubleshooting. This can be accomplished by turning off the fuse or circuit breaker that is attached to the heating unit, as appropriate.
Water temperature problems
Many different sorts of electric water heater difficulties might result in problems with the temperature of the water. The symptoms might range from a lack of hot water to insufficient hot water to water that is too hot. Having no hot water can be caused by a number of factors, including a shortage of electricity, a malfunctioning electric thermostat, or a malfunctioning top electric heating element. To begin, rule out any potential power issues. To begin, reset any tripped circuit breakers and replace any blown fuses that have been discovered.
- Replace the element if it is found to be defective after it has been tested.
- It is possible that the problem is caused by an inadequately sized water heater, crossed hot and cold connections, or a broken heating element or thermostat when the water does not heat up sufficiently.
- To rule out a crossed connection, switch off the water supply and turn on a hot water faucet; if water continues to flow, the problem is most likely a crossed connection.
- Finally, if all of the elements are operational, check the higher thermostat first, followed by the lower thermostat, and replace if either of them is not operational.
- Check to see that the upper and lower thermostats are set between 110 and 140 degrees Fahrenheit on both the higher and lower levels.
Leaks
Several factors contribute to water leaks, including a malfunctioning temperature and pressure relief valve (T P), high pressure, overheating, a jammed valve, a leak coming from an above or nearby plumbing connection, loose heating element bolts, a damaged gasket, or a leaky water storage tank. Check the T P valve by placing a bucket beneath the above pipe, opening the valve and flushing it clean; if it is still leaking, fix or replace it. Lowering the thermostat setting will therefore be necessary to alleviate excessive pressure or heat.
After that, inspect the heating element bolts and tighten them as necessary.
Finally, determine whether or not the storage tank is leaking.
Storage tanks can leak as a result of corrosion or other difficulties, such as faulty o-rings, that can occur. Keep a supply of spare o-rings from a reputable provider such as Apple Rubber on available in case you need to replace an o-ring.
Discoloration or odor
Corrosion inside a glass-lined tank or a malfunctioning sacrificial anode rod can both result in rust-colored water being produced. If the anode rod is deteriorating, a magnesium anode rod should be used to replace it. A decaying sacrificial anode rod can also leak hydrogen, resulting in a rotten egg-like odor from the rotting rod. To remedy this situation, first flush the water heater with a hose. Then, for two hours, soak the tank and pipes in a solution made of two pints of 3 percent hydrogen peroxide to 40 gallons of water for two hours.
If the odor persists, try replacing the heater with one that has been lined with plastic sheeting.
Noise
A deep, rumbling sound may suggest boiling water, which is produced by overheating as a result of sediment accumulation. This can be resolved by flushing the water heater. When scales accumulate on electrical heating components, a high-pitched, whining noise can be heard in the background. First, cleanse the water heater to get rid of the problem. After that, flush out the scale from the water heater tank and heating components. Finally, use low-wattage heating components with a bigger surface area to improve the efficiency of heat transmission.
Refinance your home
Are you in need of money to cover unforeseen expenses? If you have equity in your house, you may use it to finance home upgrades, debt repayment, or the creation of a cash reserve for emergencies. Because interest rates are still at historically low levels, now may be an excellent time to consider refinancing your current mortgage with a new one that has a lower interest rate. **Not all borrowers will be eligible for this program.

Electric Water Heater Repair and Troubleshooting
“There is no hot water” “A heating element has to be replaced” Newly installed electric water heaters may require several hours to achieve their regular working temperature. In the event that you do not have hot water after two hours (and the water is not even warm), first ensure that the water heater is receiving electrical power. The inability to obtain electrical power is a typical cause of new water heaters failing to function. “Temperature Adjustment” is an abbreviation.
Checking for Electrical Power
You can check for power using a simple “circuit tester,” but for a more thorough diagnosis of electrical issues, you’ll need a meter that measures voltage in addition to the circuit tester. Turn off the circuit breaker labeled “water heater” to see whether there is any electricity (or remove fuses). Remove the access panel on the top of the water heater. Carefully remove the insulation and plastic cover from the refrigerator. Determine the location of the power supply lines. Most of the time, they are attached to the top two screws of the upper thermostat.
- If there is none, replace the upper thermostat.
- Although most residential units are 220/240 volts (although some are 110/120 volts), others are 110/120 volts.
- If your device is not receiving the proper power, it is likely that there are problems with your home’s electrical system.
- Circuit breakers should be turned off.
- Using a Voltmeter, check the thermostat’s power supply.
- If a water heater is not entirely filled with water before electric power is introduced, the higher heating element will burn out and cause the water heater to fail (this is called Dry Fire).
- This is done to ensure that all of the air has been evacuated from the tank and that the tank is entirely filled with water before proceeding.
Replacement heating elements are affordable and easily obtained. Check to be that the tank has been entirely refilled with water once the heating element has been changed before turning the power back on. “Water Leaks” is an abbreviation.
Some Hot Water, but Not Enough (New Installation)
You may need to change the thermostats on your new water heater if it is producing hot water, but not at a rate that is consistent with your expectations or that is sufficient for your need. The Installation Manual contains instructions on how to regulate the temperature of your device, as well as vital safety advice on scalding prevention. The temperature setting for a water heater should not be greater than 120oF, according to the manufacturer. Scalding injuries are more likely to occur when temperatures are higher.
Keep in mind that temperatures beyond 120 degrees Fahrenheit might result in significant injury.
In addition, it’s conceivable that your water heater is too small or that your water use has grown.
Water Leaks
Water heater leaks are mostly always caused by faulty connections at the hot water output or cold water input on a newly installed unit. On rare occasions, leaks can be discovered coming from a fitting (such as the area around the Temperature and Pressure Relief Valve) or from one of the heating components, respectively. Fittings that are leaking may frequently be adjusted or fixed. It is quite unusual for a new tank to experience a leaking problem. “Electric Thermal Expansion Tank” is an abbreviation for “Electric Thermal Expansion Tank.”
Water Drips
Water heater leaks are mostly always caused by faulty connections at the hot water outlet or cold water input on a newly installed heater. A leak can occur from a fitting (such as the area surrounding the Temperature and Pressure Relief Valve) or from one of the heating components every now and then. It is typically possible to tighten or fix leaking fittings. It is quite unusual for a new tank to experience a leaking condition. Electric Thermal Expansion Tank is a technical term that refers to a tank that uses electricity to heat water.
Water Pressure
With a pressure gauge, you can check the water pressure in your home. The recommended water pressure is between 50 and 60 PSIG. If the pressure is higher than that, a Pressure Regulating Valve should be installed (or adjust your existing pressure regulating valve if you have one). If you are experiencing low water pressure, contact your local water provider or a competent plumber. If the water pressure is more than 80 PSIG, most plumbing standards demand the use of a Pressure Regulating Valve.
Thermal Expansion Tank
Make use of a water pressure gauge to determine the water pressure in your home. 50 to 60 PSIG is the ideal water pressure range. It is necessary to install a Pressure Regulating Valve if the pressure is higher than that limit (or adjust your existing pressure regulating valve if you have one).
Consult your local water provider or a competent plumber if you are experiencing low water pressure. When the water pressure exceeds 80 PSIG, most plumbing standards mandate the installation of a Pressure Regulating Valve.
Six Common Problems with Your Home Water Heater
Get in Touch With Us It goes without saying that your water heater is one of the most important equipment in your home. While it may not be apparent to the naked eye at all times or in the forefront of your thoughts on a daily basis, the fact is that you rely on the hot water it supplies you almost on a daily basis. As a result, even little issues can have a significant impact on the whole operation. In a household where you rely on hot water for everything from cooking to cleaning to bathing and even for usage with other appliances, a malfunctioning water heater may effectively bring your entire life to a grinding, excruciating halt.
The more you learn about these water heater problems, the more confident you will be in your ability to accurately diagnose them and then take the necessary measures on your own.
Water Leaks
Water leaks are one of the most prevalent types of water heater problems that you’ll come into. Any water heater will ultimately begin to leak due to the fact that water will corrode the tank and cause microscopic cracks or fractures over time. However, this is not necessarily an indication that your tank is the source of the leak. This might indicate that your water connections are loose if the leak appears to be coming from the very top of your tank. Ensure that your cold water inlet pipes and hot water outlet pipes are both securely linked and that none of the pipes are rattling or dangling in any way.
If your overflow pipe or pressure relief valve is leaking, you might potentially have water leaking from them.
No Hot Water
Is your tank brimming with water, yet none of it appears to be warm? It’s possible that there’s a problem with your heat source. If you have an electric water heater, this suggests that your heating elements may have failed or that the electrical connection between them may have been compromised. This might be caused by a malfunctioning pilot light or a poor gas hookup in a gas water heater. A problem with your burner as a whole might be the cause of the inability to ignite the gas even when the pilot light is illuminated.
Assuming this is the case, just reset the device and your water heater should ignite without difficulty.
Strange Smelling Hot Water
A growth of bacteria in the tank of your hot water heater may cause a weird scent to emanate when you turn on the hot water. Increase the temperature in the tank to around 140 degrees Fahrenheit, and any bacteria in the tank should die as a result of the increased heat. Make careful, however, that you do not use your hot water while operating this service, since hot water can cause significant burn damage if it comes into contact with naked flesh. Before running any hot water, raise the temperature and wait about an hour or so.
If the problem persists, you may need to have your tank cleaned with a chlorine bleach solution, which is not inexpensive.
Tank Takes Ages to Reheat
If it appears that your water heater is taking an excessive amount of time to reheat, you might be experiencing one of a number of additional issues. It’s possible that your thermostat is set too low, which implies that your burner isn’t producing enough energy to heat your water at a fast enough rate. It’s also possible that you have an issue with your gas connection, such as low gas pressure, a clogged vent flue, or a clogged burner orifice, which is preventing appropriate gas flow from occurring.
However, in many circumstances, a water heater requiring an excessive amount of time to reheat is simply due to the fact that the water heater does not have enough capacity to adequately service a residence.
This gives the impression that your water heater never heats up again, while in reality it just hasn’t had enough time to do so.
Low Hot Water Pressure
The smaller, 12-inch plumbing that was the architectural norm for decades is the most significant source of water pressure reduction in older homes. Modern homes are equipped with bigger 34″ plumbing that can handle higher water flow, but in older homes, the only option to resolve this issue is with a complete repiping project. And it is no minor undertaking. However, if you have contemporary plumbing in your house, you may be able to enhance your water pressure by making sure that the aerators in your sink are not blocked with debris (which they do over time).
Water Too Hot or Too Cold
Do you have a water heater that has variable water temperatures? Is the water either too hot or not hot enough, no matter how you alter the temperature on your water heater? This is a telltale indicator that your thermostat is malfunctioning. It is possible that your thermocouple may need to be changed or cleaned in order for it to begin sensing temperatures properly again. Water that is too cold, on the other hand, may be an indication of a problem with the gas flow. As a result, if your gas supply is restricted or insufficient for your requirements, your burner will be unable to sufficiently heat the water in your storage tank.
