Replacing the heating element in your water heater is a DIY job that most homeowners can do without professional assistance. This task is best done during a time when your water heater isn’t in use, so you can avoid disrupting your household’s water supply. Additionally, you should never attempt to replace the heating element on an electric water heater while it is plugged in and connected to the grid; doing so may pose a risk to your safety and the safety of anyone else in your home who may be in contact with water as a result of this repair.
Confirm that the water heater is an electric unit
If you’re replacing the heating element of an electric water heater, you’ll need to confirm that the unit is electric. This can be a bit tricky, as there are many different types of electric water heaters. If you have an electric water heater, it will have a metal or plastic cover, a power cord, and two red wires that connect to the electrical supply. You can confirm that the unit is electric by measuring the voltage at the outlet using a multimeter. Some electric water heaters have a voltage of 240 volts, while others have a voltage of 208 volts.
Turn off the power to the water heater
Before you begin replacing your water heater’s heating element, you’ll need to turn off the power to the unit. Most electric water heaters are wired in series, which means that if the power is still on, it will keep the water flowing. This is why it’s essential to turn off the power before beginning your repair. If you forget to turn off the power, your water heater will begin to operate again once the cooling process has begun.
Step 1: Unhook the power cable
If you’ve forgotten to turn off the power, the first thing you’ll need to do is unhook the power cable. This can be a bit tricky, as you may need to remove the cover to get to the wires. Electric water heaters have two red wires, as well as a ground wire that’s usually green or blue. Make sure to unhook the power cable from the two red wires, as well as the ground wire.
Step 2: Disconnect the plumbing
Once you’ve unhooked the power cable, you’ll need to remove the supply lines from the water heater. It’s generally best to do this while the water is flowing, as it will allow you to collect any leaks that may occur. If you’re replacing the heating element on a gas water heater, you’ll first need to shut off the gas supply to the unit. It’s best to shut off the gas supply before disconnecting the supply lines, as you don’t want to risk a gas explosion while you’re working on the water heater.
Step 3: Remove the old heating element
To replace the heating element on an electric water heater, you’ll need to remove the old element. This can be a bit tricky, as you may need to loosen the bolts that secure the element to the unit. You may want to use a wrench to loosen the bolts, as it will make it easier to remove the element. Once the bolts are removed, you can pry the element out of the water heater. Make sure to wear a protective face mask when working around chemicals, such as calcium-chloride, used in water softeners.
Step 4: Install the new heating element
To install the new element, you’ll need to shut off the water supply and then plug the unit back in. Make sure there is no water flowing through the pipes before you begin replacing the element, or you could be risking a pipe burst near the water heater. Once the water supply has been shut off, you can remove the old element and replace it with the new one. Make sure to tighten the bolts on the new element to ensure that it’s secure. Once the new element is in place, you can plug the unit back in and turn the power back on.
Final Words

This task is best done during a time when your water heater isn’t in use, so you can avoid disrupting your household’s water supply. Additionally, you should never attempt to replace the heating element on an electric water heater while it is plugged in and connected to the grid; doing so may pose a risk to your safety and the safety of anyone else in your home who may be in contact with water as a result of this repair.
