How to Troubleshoot and Repair an Electric Water Heater

Electric water heaters have upper and lower electrical resistance heating elements.

Electric water heaters look similar to their gas fueled cousin. They both use an insulated storage tank jacket made of steel with insulation between the storage tank and the tank jacket to reduce heat loss of the heated water.

However, in an electric water heater, the water is heated using an upper and lower heating element as opposed to a gas burner used with a gas water heater. Think of it this way, a gas water heater uses a heating system like a gas furnace and the electric water heater uses a heating element like an electric oven.

Gas or electric water heaters are one of the most dependable appliances in our homes and the electric version of the water heater is tops in reliability. There are no moving parts to speak of and repairs, when needed, are easy to make.

In this tutorial I will walk you through some of the most common electric water heater problems you may experience and how to troubleshoot and repair them.

    Let's take a look at these problems and what possible causes and repairs you can try:
