How to Fix Hot Water Heater Element: Quick DIY Guide!


Debarghya Roy

When it comes to fixing a hot water heater element, there are a few key points to know. Let’s get into it!

  • First, the heating element in your hot water heater is what provides the heat to warm up the water. Over time, these elements can wear out and stop working.
  • So, to start, make sure to turn off the power supply to your water heater. You can do this with the circuit breaker or by shutting off the gas valve.
  • Next, you need to find the access panel on your water heater. It’s usually near the bottom of the tank and you can remove it with a screwdriver or wrench.
  • Using a circuit tester, check for electrical power at the terminal screws of both heating elements. If there is power, but no heat, it’s likely one or both of the elements need replacing.
  • To replace, you need to drain the water from your hot water heater. Then, use an inch socket wrench to disconnect the wires from the terminal screws.
  • Once removed, loosen and remove each heating element with an element wrench or pipe wrench. Dispose of any old gaskets and clean around each opening before installing new elements.
  • Insert new elements into their respective openings, ensuring they are screwed in clockwise. Attach the wires to the terminal screws and make sure they’re secure.
  • Now fill your hot water heater with water again. Open a hot water faucet in your house to let out any air.
  • Turn on the power supply to your hot water heater. The heating elements should start generating heat soon.

Pro Tip: To extend the life of your elements, test them often and consider getting a thermal expansion tank. It helps reduce pressure in the system, reducing stress on the elements.

Now you know how to fix a hot water heater element. Be careful when working with electrical power and consult a pro if you have doubts.

Understanding the Hot Water Heater Element

Comprehending the Hot Water Heater Element involves understanding its components. These are:

ComponentDescription
Heating ElementFor heating water in the tank.
WattagePower rating, measured in watts.
Watt DensityPower output per square inch of element surface area.
High Watt DensityElements with high power output, quick heating, but prone to burn out.
