Electric Water Heater Too Hot | Troubleshooting and Repair


A water heating unit that supplies you with hot water every day without fail is indeed precious. However, when it’s already overheating, you surely have to be cautious and fix the problem ASAP to prevent accidents. As we all know, boiling hot water can easily burn your skin in a matter of seconds. You surely don’t want such kinds of accidents to occur especially if you have kids at home. To help you properly troubleshoot and repair an overheating water heater, follow these valuable tips.

1. Check The Water Heater’s Temperature Setting.

Your water heater features a thermostat that will allow you to configure the temperature of the water. Check its current setting just in case someone just adjusted it without your knowledge. Make sure that the temp won’t exceed 120 degrees because that level is already enough for your hot water requirements. If it’s set too high, lower the temp down and observe if that will solve the problem.

2. Inspect The Thermostat And Make Sure It’s Not Damaged.

There will come a point when the water heater will overheat because the thermostat’s no longer working properly. Fortunately, most water heating units feature thermostats that have a reset button. When the appliance continuously warms water, the reset button should be activated. Doing so will stop the water heater from drawing power thus halting the elements from heating water. When the reset button is damaged, note that they can easily be replaced.

3. Even The Pressure Relief Valve May Cause Your Water Heater To Overheat.

The pressure relief valve is located at the top or at the side of your water heater. It’s responsible for allowing steam to get out of the tank. When steam fails to escape through the valve, your tank may get damaged and accidents may happen, putting your loved ones’ lives at risk. In cases when the pressure relief valve malfunctions, you have to call a licensed plumber to have it checked and repaired immediately.

4. Take Care Of Your Water Heater’s Upper And Lower Heating Elements.

Hard water contains sediments or dissolved minerals that are not eliminated during the process of water purification. As the water gets into your water heater tank and gets warmed up by its upper and lower heating elements, there are instances when these sediments stick to the said metal parts. Now the problem begins when the elements are coated with the sediments because they will then have difficulties in heating up water, thus overheating the appliance. To resolve this issue, you have to regularly flush your water heater tank and replace the elements whenever necessary.
