Troubleshooting the Problem
Before diving into any repairs, it is important to understand the problem first. Some common problems electric water heaters encounter include a lack of hot water, strange noises, and leaking. If your electric water heater is not producing hot water, check the circuit breaker, thermostat, and heating elements for any signs of damage.

Necessary Tools for Troubleshooting and Repairing an Electric Water Heater
Before you start troubleshooting your electric water heater, you’ll need a few tools. Here are some of the essential tools you’ll need:
- Wire cutter/stripper
- Element wrench
- Drain valve wrench
Turning Off the Power and Water Supply
Before starting any repairs, it is essential to turn off the power supply of the water heater for safety purposes. Depending on the unit, you may need to turn off the circuit breaker or switch off the power supply via the disconnect box.
Next, turn off the water supply that leads to the electric water heater. If you need help locating the valve, follow the pipe that leads to the water heater, and the valve should be nearby. Shutting off the water supply prevents water from flowing while repairing the heater.
Replacing the Heating Elements
If the heating elements of the electric water heater are not functioning, replace them. Wear appropriate gear and use a voltage tester to confirm the power supply is disconnected before you begin work.
Detach the heating elements, remove the old ones, and replace them with new ones. Ensure that the product is compatible with your specific electric water heater. Fill the tank with water, then turn the power back on. Turn the heater knob and check if the hot water is running again.
Replacing the Thermostat
Controlling the heating system of the electric water heater is the thermostat. If your water heater is not heating the water properly, check the thermostat. It might have malfunctioned and needs to be replaced. Some thermostats come attached to the heating element, while others come individually. Check the make and model of your unit, and then replace the damaged thermostat.
Flushing the Tank
If you notice strange noises, rust-colored water, or a lack of hot water, it might be due to sediment buildup in the tank. It would help to flush the tank to remove any sediment buildup at least once yearly. Wear protective gear and turn off the power and water supply of the water heater.
Attach a hose to the bottom of the tank, then turn on the hot water taps inside your house. Let the water flow through the tank and drain. Once the water is clear, turn the water and power supply back on, then turn on the heater.
