How To Replace A Water Heater Element

How to Replace a Water Heater Element: A Step-by-Step Guide

It is possible that a water heater element may need to be changed. It is not necessary to replace your water heater only because the heating element has stopped working; instead, you may repair or replace it. Although changing a water heater element may appear to be a challenging undertaking, the majority of homeowners are capable of doing this repair themselves. The likelihood that one or both of your water heater’s heating elements are malfunctioning is high if your water heater takes a long time to heat up, runs out of hot water, or fails to supply any hot water at all.

Replacing a Hot Water Heater Element

If your water heater is more than six years old, you may want to think about replacing it with a new one. Water heaters normally have a lifespan of 6 to 10 years, so if your heater is more than a decade old, you may anticipate it to begin having difficulties much sooner rather than later. As a bonus, because modern water heaters are more energy efficient than older models, you’ll save money on your monthly utility bills as well.

Checking Your Water Heater Heating Element

Before rushing in and replacing your water heater’s heating element, make sure that the element is, in fact, the source of the problem. Sometimes, after replacing the heating element, it is discovered that the problem was not with the heating element in the first place. This can be accomplished by first checking to see whether a circuit breaker has been tripped or if the power has been mistakenly turned off. If the breaker is in good working order, the next step is to examine the reset button on the temperature cutoff device.

It’s usually represented with a red button.

If you have access to a multimeter, you may verify the continuity of the element.

Using this brief video, you will be guided through the procedure step-by-step.

Preparing to Change Your Water Heater’s Heating Element

The heating elements are sometimes referred to as immersion heaters since they are completely submerged in the water of the tank during operation. Keep in mind that heating components are only utilized on electric water heaters, which is vital to know. Gas water heaters heat water in a completely different way than electric water heaters.

Heating Element Style

There are two distinct types of heating elements: infrared and radiant. Screw-in: This is the sort of heating element that we will be discussing because it is the most prevalent. They are commonly found on all modern water heaters, and the element is secured in place with a screwdriver. Installed as a bolt-in element: There are various distinct designs for bolt-in elements, and if you have an older water heater, it’s probable that this kind was used.

The element is held in place by four bolts that go through it. If you wish to convert a screw-in element into a bolt-in element, you may purchase a universal adapter kit to do so.

Heating Element Location

Electric water heaters are equipped with two heating components. There are two elements: an upper part that is hidden behind the upper access panel and a bottom element that is visible from the outside. Typically, the lowest piece is the one that has to be repaired or replaced. As the sediment in your tank builds up, it will eventually settle in the bottom of the tank, where your lower element is located. The silt encircles the element, reducing its ability to perform its function. Eventually, it will either entirely fail or utterly short out on you.

Today is the day to fix your plumbing emergency!

Purchasing New Heating Elements

Purchase new heating elements with the same voltage, wattage, and type (screw-in or bolt-in) as the heating element you are replacing if you want to keep your existing system running efficiently. The new element’s voltage should always be the same as the voltage of the old element. However, if you want to lengthen the life of the element, you might choose a lesser wattage. You should keep in mind that the element will also produce less heat. Never replace an element with a higher wattage than the one you replaced.

If you are unable to locate it, you can always conduct a simple web search using the model number of your water heater (found on the name plate).

Types of Water Heater Elements

There are three different kinds of water heater elements. It is possible that your water heater is reaching the end of its service life and that you will wish to replace it with the least costly high watt density element available. The other, more expensive solutions should be considered if your heater is modern and you reside in a region where hard water is prevalent. Consider each of the following in further detail:

High Watt Density Heating Element

When it comes to water heater elements, High Watt Density Elements are the most popular and may be utilized in any replacement scenario as long as the wattage and voltage are compatible. In the majority of situations, a high watt density element will be the same type of element that was originally installed in your water heater. The corrosion of high-wattage density components results in a reduced life cycle for the elements. You may anticipate that these elements will be the least expensive of the three types to be purchased.

Low Watt Density Heating Element

Those who live in places with hard water will benefit from low-wattage density components. Many are constructed with a fold-back design to provide more heating area. Despite the fact that they have a lower watt density, there is no reduction in efficiency. The lime scale build-up that is frequent in locations with hard water can be reduced as a result of this. You can use a low watt density element to replace a high watt density element as long as the wattage and voltage are the same as the original element.

Element with a Low Watt Density (DERNORD) The DERNORD Foldback heating element has a low watt density and is ideal for small spaces. It is offered in two power ratings: 4500 watts and 5500 watts.

Lime Life Element

A limited 5-year guarantee is provided on these high-end components. Lime life elements feature an ultra-low watt density and a high-quality nickel and stainless steel surface that prevents the accumulation of lime scale on the element’s surface. Because they are resistant to dry burning, these components are an ideal choice if you live in a region where water supply levels are inconsistent. Lime life components are often the most costly element; yet, once installed, they will frequently outlast the life of the water heater itself.

It is offered in three different power ratings: 4500 watts, 5500 watts, and 6500 watts.

Necessary Supplies

You’ll need the following items in order to make changes to an element:

  • The following items are required: garden hose, water heater element wrench, voltage tester, new heating element with “O” ring.

Replacing a Heating Element

Replacing the heating element in a water heater is a reasonably straightforward procedure. Keep in mind, though, that you will be working with both electricity and water, which are two things that should not be mixed in any way. If you are not comfortable with the situation, you should contact a certified plumber. Your first and foremost concern should always be safety.

How to Replace a Heating Element

Step 1: Turn off the electricity.

  • Circuit breakers are located in the electrical panel and should be turned off. Check the voltage of the water heater to ensure that the electricity is no longer reaching the water heater. Due to the fact that you will be dealing with electricity and water, it is necessary that the water heater be switched off before beginning.

2nd step: connect the drain hose to the drain valve

  • Connect a hose to the drain valve and turn the valve to the open position. It is NOT necessary at this time to drain the tank
  • Rather, it is simply necessary to check to see that the drain valve is not blocked. If your tank is blocked, you’ll need to deal with it first
  • Otherwise, move on. Please do not empty your tank at this time. See the next section for instructions on how to replace a heating element without emptying your tank.

Step 3: Shut off the water supply.

  • Close the cold water inlet valve on the water heater, which is often placed above the water heater, to turn off the water supply to the water heater. Allowing air to enter the tank will relieve the pressure in the hot water system. To accomplish this, turn on a nearby faucet. Only the hot water tap should be opened, not the cold. Make certain that the tap is left open.

Step 4: Remove the Access Panel Cover from the Access Panel.

  • To remove the cover from the access panel, use a screwdriver to pry it up. The upper water heater element is housed within the upper panel. The lower element is housed in the lower panel, and there is normally insulation between the panel door and the thermostat itself. Set the insulation away in a cool, dry location
  • The thermostat should be protected by a plastic casing. Remove the lid in a gentle manner. Check the cables with a volt meter to make sure there is no electricity flowing through them
  • Examine the electrical wiring. Is there any damage to any of the wires? Is there anything that has melted? An element that has become overheated as a result of silt might cause damage to the wiring. It is necessary to repair any damaged wiring. Disconnect the two element wires from the heating element by loosening the screws that hold them in place.

Step 5: Disconnect the heating element from the circuit.

  • To remove the heating element, use a heating element wrench. With a large mouth that fits over the exposed section of the element, it’s particularly intended for removing electric water heater elements from water heaters. Whilst the tank is still partially filled with water, loosen the element by rotating it in a counter-clockwise direction. The weight of the water will assist in keeping the tank in place. Drain the tank by opening the drain valve after you’re satisfied that you’ve been able to release the heating element. This might take anything from a few minutes to an hour, depending on the size of your tank. Remove the element from the equation. A rubber gasket, often known as a “O” ring, will be used to seal the tank. Make certain to remove the “O” ring that came with the element.

Installing the New Heating Element is the sixth step.

  • Clear away any dirt or debris from the threads and gasket region of the replacement element before installing it. Attach the new “O” ring to the new element using the new “O” ring. NEVER EVER EVER EVER use the old “O” ring
  • To install the element, gently put it into the tank and tighten it with the element wrench. Attach the two wires to the element and secure them in place by tightening the screws that hold them in position. Ensure that the wires are tight and will not slip by checking them twice.

Step 7: Fill the Tank with Water

  • Drain the water heater by closing the drain valve. Turn the water supply to the water heater on. At this time, do not switch on the electricity. If the tank is not completely filled with water before turning on the electricity, the heating components will be damaged. Ensure that the newly installed piece does not have any leaks. Turning off the cold water supply and tightening the element will stop any leaks from occurring. Removing the element and repositioning the “O” ring may be essential in some cases. It is normal for water to begin sputtering out of the open faucet tap as the tank fills (left open in Step 3). The water is forcing the air out of the line as it flows through it. As soon as there is a consistent flow of water, the faucet may be turned off. Replace the plastic thermostat cover, insulation, and access panel cover with new materials. You may turn the electricity back on to the water heater once the tank has been fully refilled by flicking the circuit breaker back on. The fact that there will almost certainly be air in the hot water pipes means that it is not unusual for the hot water taps throughout the home to splutter. Fortunately, this will subside in a short amount of time. Open each faucet individually, if desired, until you get a continuous stream of water
  • However, this is not necessary.

Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. The procedures necessary for both flange and screw-in models are almost identical, however screw-in models are more frequent and will necessitate the use of a specific instrument known as a water heater element wrench.

Turn Off the Power

Whenever you are working on a water heater, you should always cut off the electricity. Electric units may be turned off by turning the circuit breaker, however gas units will have a knob or dial to turn off the gas. If you are unsure whether or not your electric water heater is turned off, use a voltmeter to check the wiring before you start.

Drain the Tank

Close the cold water inlet valve, which is positioned on the tank’s top, and turn off the water supply. Connect a garden hose to the drain at the bottom of the tank and turn on the drain valve to allow the water to flow out. Even though you only need to drain the unit to a point below the heating element, it is a good idea to thoroughly cleanse the tank whenever you are performing maintenance.

This aids in the reduction of sedimentary deposits in the tank as well as the extension of the life of all components. Make sure to turn on the hot water faucet that is closest to the heater in order to properly drain the system.

Remove the Existing Element

Your water heater may be equipped with two elements: an upper element and a lower element. If this is the case, both components are changed using the same procedure. To begin, open the access panel and remove the plastic safety cover, if one is present, from the vehicle. Disconnect the wires from the element using a crimping tool. To save time, you may just disconnect the cables from both parts at the same time. An element tool, also known as a water heater element wrench, is a specifically designed socket that fits over the hex end of the element and has a hole in the other end that will receive the shaft of a screwdriver.

It may be tough to turn elements that have been in place for a lengthy period of time.

After the element has been unscrewed from the unit, it will simply lift out of the unit.

Install the New Element

When changing a water heater element, be sure to replace the rubber gasket as well to avoid leaks in the future. Placing the gasket over the threads of a screwed-in element or around the base of a flanged element is recommended. Install the replacement element by reversing the procedure of removal and spinning the element in a clockwise direction while the gasket is still in place on the old element. Then use your water heater element wrench to tighten the component another 1/2 to 1 turn after it has been finger-tightened.

Refill the Tank

Drain the tank by closing the drain valve located at the bottom of the tank. Start by turning on the cold water intake on the tank’s top. Your water heater may make noises if you leave the hot water faucet turned on. This noise might be anything from a sputtering sound to a rattling sound as water is driven through the pipes. Allow the water to run until all of the air has been expelled from the pipes. Turn off the hot water faucet if it is still running.

Reconnect andRepower

Drain the tank by closing the drain valve located at the bottom. Start by turning on the cold water input on the tank’s roof. Your water heater may make noises if you leave the hot water faucet turned on. This noise might be anything from a sputtering noise to a rattling noise as water is driven through the pipes. Allocate enough time for water to flow through the pipes until all air has been expelled. The hot water faucet should be turned off.

Typical Electric Water Heater ConstructionWiring Diagram

Electric water heaters, in contrast to gas water heaters, which heat the water via the use of gas burners, heat the water through the use of a pair of upper and lower metal heating elements. The heating elements of a water heater operate in a manner similar to that of oven heating elements, in that they heat up when electrical current runs through them. Using a separate thermostat, each of the heating components may be regulated independently.

Before You Begin

Despite the fact that replacing a broken heating element on an electric water heater is not very difficult, it is categorized as an advanced job since it takes both mechanical competence and a thorough understanding of electrical wiring concerns.

Specifically, it entails three main project stages:

  1. Putting the heating element through its paces
  2. Removing the old heating element A new heating element is being installed:

Warning

Because of the electrical expertise necessary for this job, it is recommended that an electrician complete this work. It’s possible that you’ll be dealing with high voltage, so if you’re not comfortable with electrical work, you should consult with an expert to reduce the danger of damage. Heating components are not especially expensive, therefore it is possible that you will wish to replace both of them even if only one of them has been found to be defective. If one heating element fails, it is conceivable that the other will fail shortly after, and replacing both heating elements at the same time can help to avoid a second repair in the near future.

Materials

You will need to be familiar with the usage of a multimeter in order to test the heating element of an electric water heater.

Turn off the Power

  • Turn off the power to the electric water heater at the main power panel by removing the fuse that controls the power to the water heater’s circuit or by turning off the circuit breaker that controls power to the water heater’s circuit. Wait for the water in the tank to calm down, which might take up to two hours or longer. Important because the heating elements are regulated by thermostats, and hot water in the tank will alter the electrical flow to the heating components, making this a critical consideration. Open a hot water faucet and let the water run to be sure it is cold before continuing.

Expose the Heating Element

  • Remove the access cover panel and the insulation protecting the heating element terminal block from the heating element terminal block. When you fold the insulation outward and away from the heating element, it will be more effective. The screw terminals where the circuit wires are linked to the heating element will be exposed as a result of this. To check for power, use a non-contact circuit tester to probe the wires. Following your confirmation that the power has been turned off, unscrew the screws securing the wires to each of the two terminal screws and remove the circuit wires from the circuit.

Test the Heating Element

  1. Remove the access cover panel and the insulation covering the heating element terminal block from the heating element terminal block and place them aside. In order to keep the insulation from getting too hot, fold it outward and away from the heater. The screw terminals where the circuit wires are attached to the heating element will be exposed as a result of this procedure. To check the wires for power, use a non-contact circuit tester. Following your confirmation that the power has been turned off, loosen the screws securing the wires to each of the two terminal screws and remove the circuit wires from the terminal screws.

How to Remove a Heating Element

The removal of the heating element can begin immediately after the heating element has been tested and found to be functional (see above).

Turn off the Power and Water

  • You should shut off the electric water heater at the main electrical panel, if you haven’t already done so. To do so, locate and switch off the circuit breaker or fuse that powers the heater (see above). Shut down the cold water supply line that supplies hot water to the water heater. An example of where you could find this shut-off valve is on the cold-water line that enters the water heater, right above the water heater.

Expose the Heating Element

  • Assuming you haven’t already done so, remove the access cover panel as well as the insulation that covers the heating element terminal block. When you fold the insulation outward and away from the heating element, it will be less likely to catch on fire. Using a non-contact circuit tester, check to see that the power has been turned off. Remove the thermostat cover from the thermostat if it’s required to do so. Make certain that the connecting point that connects the thermostat to the heating element is disconnected. Disconnect the circuit wires by loosening the screws that hold the wires to each of the two terminal screws
  • Then tighten the screws again.

Drain the Water Heater

  • To drain the water heater, connect a garden hose to the drain spigot on the water heater and run it to a floor drain to empty the water heater. To drain the water from the water heater tank, open the drain valve and turn it on.

Remove the Heating Element

  1. To drain the water heater, connect a garden hose to the drain spigot on the water heater and run it to a floor drain to collect the water. Drain water from the water heater tank by opening the drain valve.

How to Install a New Heating Element

The replacement heating element may be placed immediately after the old malfunctioning heating element has been checked and removed (see above).

Check Specifications

  • Check to be that the replacement element has the right voltage and wattage rating for your water heater before installing it. On the flange or terminal block of the heating element, or on the data plate of the water heater, you should be able to discover this information.

Insert the New Heating Element

  • Using a cloth, wipe out the area around where the gasket attaches to the tank to remove any debris. Install the replacement gasket on the heating element and then put the entire assembly into the water heater’s tank of storage. Tighten a screw-in-type heating element by threading it into the tank opening with a socket wrench in a clockwise direction until it is securely fastened. Insert the four mounting screws into the flange-type heating elements and tighten them down firmly to secure them

Refill the Water Heater Tank

  • Drain the water heater by closing the drain valve. Open the cold water inflow valve as well as the nearest hot water faucet at the same time. Allow three minutes for the hot water faucet to remain open after you have achieved a consistent flow of water. As a result, any surplus air and sediment will be removed from the lines. Examine the area surrounding the heating element for leaks.

Make Wire Connections

  • Connect the black and white circuit wires to the heating element’s screw terminals by wrapping the wires around the terminals in a clockwise orientation. The wire that is connected to the screw terminal does not matter which one it is on. Adjust the wires to ensure that they are securely fastened once you have completely tightened the screws.

Reassemble the Cover Plate

  • In order to properly reinstall the thermostat cover, you must first tuck the insulation back into its original location before reattaching it to the water heater tank.

Turn on Power and Test

  1. Switching on the water heater’s circuit breaker will bring the electricity to the unit on. Allow the water to warm up for many hours before checking the temperature of the water with a probe. If you need to make any modifications to the thermostat, do so.

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. Because they’re affordable (around $20 for both the thermostat and the cutoff switch), you could just replace them rather than go through the trouble of testing them.

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.

Estimates are provided without obligation. The water heater element on your electric water heater should be checked if you’ve noticed that the hot water doesn’t last as long as it used to, or if you’re only receiving tepid water. If this is the case, replace the element. Even though a broken water heater element occurs at the most inconvenient of times, it is a pretty simple repair. A water heater element may be purchased for anywhere from $10 and $60 at most home improvement stores. A water heating element replacement is a do-it-yourself project if you’re experienced with basic electrical work.

Safety Considerations

Before changing a water heater element, be sure that the power to the water heater has been turned off at the main electrical panel.

Check the water heater element with a non-contact circuit tester to ensure that there is no current flowing through the element when it is time to inspect it.

Tools and Materials

  • Element remover, screwdriver, multimeter, non-contact circuit tester, socket wrench and sockets, heating element, rags, and other supplies

Instructions

To turn off your water heater, locate the circuit breaker for it in the main electrical panel and turn it off or remove the fuse, if you are using fuses. Allowing the water in the tank to cool for a period of time before testing the water is recommended. Before moving on, check a hot water faucet to verify whether the water is still hot enough to use.

2. Access Heating Element

Locate the access cover panel on the water heater and carefully remove it from the unit. Fold the insulation back and away from the heating element in order to reveal the screw terminals and circuit wires behind the layer of insulation. Check the wires using a non-contact circuit tester to check whether any electricity is flowing through them. If there is no power, unscrew the screws and unhook the wires from the circuit breaker.

3. Test the Heating Element

To obtain an OHM reading, you’ll need a multimeter. if the multimeter displays the letter O, it means that the heating element has to be changed. However, if you do obtain a reading, it is possible that the fault is with the other heating element.

4. Drain the Water Heater

Turn off the cold water supply line to the water heater while the electricity to the water heater is turned off as well. It is customary to locate the cutoff above the water heater. Drain the water heater by attaching a garden hose to it and letting it run. Drain the water heater water by placing the hose on top of a floor drain and allowing it to drain until the water line is below the element.

5. Remove the Heating Element

Water heaters contain two types of heating elements: screw-in heating elements and flange-type heating elements. Turn the heating element counterclockwise with a socket wrench fitted with a 1 12-inch socket when working with a screw-in element. Remove the screws and gasket by heating them with a flange-type heating source. Remove the heating element from the water heater after it has been disconnected.

  2. If you are getting less hot water than normal, replace the bottom element. The water supply valve for the electric water heater should be turned off. The water heater’s cutoff will be positioned on the top of the unit (on the cold-water inlet pipe). Afterwards, cut off the electricity to the water heater at the main electrical panel
  3. A garden hose should be connected to the drain valve located at the bottom of the tank. Empty the tank down the drain in your basement. Close the valve and pull the hose out of the way.

Why Does My Water Heater Element Keep Going Bad?

A broken or malfunctioning water heater is an unpleasant experience, especially when you’re in the middle of getting ready to take a shower or make a dinner. When the water pouring out of your faucets is chilly, the water heater is almost always to blame, according to the experts. It’s possible that the heating element in the unit has failed and will need to be replaced; this is something to look into. However, if your water heater element continues to malfunction, it’s critical to determine what could be causing the problem.

What Causes a Heating Element to Burn Out?

Electric water heaters are the only ones that rely on heating elements to warm the water in the tank. A burner is located at the bottom of a gas-powered device. As a result, if your water heater is electric, the element will come into direct touch with the water, which implies that any foreign objects in your water might be the source of the problem. However, it is possible that the wiring to your electric water heater is the source of the problem. Because power is supplied to the components of your unit via heavy gauge wires, a bad connection between the cables and the water heater might result in the element failing to function properly.

  • A hot wire might pose a safety danger, especially if it connects to the earth via the tank’s metal surface.
  • Power surges can occur during electrical storms or if the power provider encounters a surge on the opposite end of the line at the same time as the storm.
  • It is possible to avoid this from occurring in your house by having surge protection installed by a professional electrician.
  • If your heating element continues to burn out after a sudden and unexpected surge of power, you may want to explore one of the solutions listed above.
  • Suppose it were to function without any water in the tank, it would be able to generate enough heat to completely burn up its core in a short amount of time.
  • If air pockets develop in the tank, which is frequently the result of a failure to thoroughly bleed out the tank before filling it up, the element may be burning itself out owing to a lack of sufficient water.

As a result, it is possible that the heating element will fail more quickly and frequently than it should. A plumber may inspect inside the tank to see if there are any air pockets that are creating the problem, and they can also check to see that the element is completely immersed in the water.

In the same way that any other component in an appliance isn’t intended to endure indefinitely, the heating element in your water heater is not. In fact, the presence of mineral deposits in the water accelerates the death of this component since the process of heating the water leads the dissolved minerals to revert to their solid states, which speeds up the decay. Those minerals frequently form a protective layer over the heating element, which acts as an insulator and stops the element from transmitting heat to the water.

When this occurs, the element is forced to work harder to heat the tank, increasing the amount of pressure placed on it.

Keeping this from happening is as simple as turning off the electricity to the tank and emptying the water out once every few months.

Repairable Issues

Water heaters are relatively straightforward gadgets that include no moving parts: Once the water has been pumped into the tank, it is heated by a gas or electric-powered element and then circulated around the house as needed. As a result, the following fundamental problems might arise, each of which is easily remedied:

  • The thermostat malfunctions
  • The pilot light on the gas heater goes out. Failure of a gas burner or an electric heating element The pressure-relief valve becomes stuck.

How To Change Heating Element In Water Heater

In Part One of this blog series on electric water heaters, you learned how a water heater works and how to troubleshoot some typical problems that may arise. Following up on our promise at the end of part 1, we’ll show you how to replace the heating components in your water heater. It’s a more difficult task, yet it’s also easy, uncomplicated, and rather rudimentary in nature. You should be able to do it on your own. Given that we always follow through on our promises, here’s how to replace the heating components in your electric water heater:

Getting Started

When working on electrical items, the first thing you should always do is switch off the power to the device you’re working on. Go to your circuit breaker panel and turn the circuit breaker linked with your electric water heater to the off position. This is really crucial! After you’ve made certain that the power has been turned off, you should look for the heating components themselves. There are two of them, and they’re both submerged in water. You are not need to enter the take to gain access to them.

Changing only the top heating element necessitates only a partial draining of the tank until the element is no longer submerged in water.

Empty the tank

  • Turn off the cold water supply to the water heater. Make a small opening in the hot water faucet to allow air to enter the tank as it empties. A garden hose should be connected to the drain valve located at the bottom of the tank
  • The other end of the hose should be placed such that the water drains into a floor drain (or a bucket)
  • Drain the water heater tank by opening the drain valve located at the bottom of the unit.

Close the drain valve when the tank is completely empty (or almost empty enough to reveal the top portion). Afterwards, gently detach the wires from the heating element using tongs.

Remove the heating element

This step will necessitate the use of a wrench. If the heating element is held in place by bolts in a flange, you will need to remove the bolts using a wrench. If the typeheating element is screwed into the machine, use the wrench to twist the element counter-clockwise until it comes loose. Regardless of which type you have, gently remove the heating element after it has become loose. Once the element has been removed, clean the tank surrounding the entrance for the element using a wire brush or sandpaper.

  1. The element should be replaced with care so that nothing interferes with the installation of a flawless seal.
  2. All of the information on the water heater’s nameplate should be written down or photographed for future reference.
  3. It is possible that you may wish to bring the old element so that you can compare it to the new element.
  4. Once you’ve received your replacement element(s), it’s time to put the gasket on them (s).

Install the new heating element

Reversing the procedures you followed to remove your old heating element will allow you to quickly and easily replace your new heating element. If your previous heating element was held in place by bolts in a flange, you’ll need to tighten the bolts using a wrench to prevent them from falling out. You may tighten them similarly to how you tighten the lug nuts on your car tire: start with one nut that is just slightly fastened and go on to the other side of the car with another nut that is only slightly tightened, and so on.

  1. Don’t overtighten the screws.
  2. You are not need to apply Teflon tape on the threads unless specifically instructed to do so by the new element.
  3. When you’ve gotten the element as snug as possible, you may move on to the next step.
  4. Check to see that the hot water faucet is still operational.

First, simply a stream of air will be released from the hot water faucet. Soon, the hot water faucet will spew air and unclean water, and the situation will be dire. Pour more water into the tank until the hot water faucet no longer sputters when you turn on the hot water faucet.

Turn off the hot water faucet

Check to see if any water is leaking from the faucet. If there is, tighten it and repeat the process as needed. If you are unable to halt the leak, you will be need to repeat all of the actions above. Always clean the tank opening and the element to provide a tighter seal between the tank and the element. Reconnect the cables to the heating element after there are no more leaks to be found. Please keep in mind that the heating components must be completely submerged in water before the power is turned back on.

Make certain that the components are completely immersed!

Turn the power back on

The water will begin to heat up as soon as you do this, and the pipes leading to the hot water taps will begin to fill up with water once more. When this occurs, you may experience what is known as “water hammer.” To avoid this, ensure that your hot water pipes are progressively refilled by opening the hot water taps a bit at a time. Additionally, you may want to remove shower heads, aerators from sink faucets, and spray heads in order to avoid silt from blocking the fixtures. That’s all there is to it!

A pleasant, lengthy, and soothing bath or shower is called for.
