Steps For Resetting Your Water Heater
If your water heater stops working, it can be an inconvenience. Most of the time, you can reset it, and it will start functioning again. However, resetting a water heater can be a daunting task, especially if you have never done it before.
In this blog post, we will guide you through the steps for resetting your water heater so that you can do it quickly and easily.
Step 1: Locate The Reset Button
The first step to resetting your water heater is to locate the reset button. The reset button is usually a red button located on the front panel of your water heater, near the thermostat. Once you have located the reset button, make sure that the power to the water heater is turned off.
Step 2: Press The Reset Button
Once you have turned off the power to the water heater, press the reset button. You should feel a click when you push the button. If you do not feel a click, it might be because the button has already been tripped.
In this case, you should call a professional to come and look at your water heater.
Step 3: Wait For The Water To Heat Up
After you have pressed the reset button, turn the power back on to the water heater. You will need to wait for the water to heat up again. This usually takes about 20 to 30 minutes, depending on the size of the water heater.
Step 4: Test The Water Temperature
Once the water has heated up, you will need to test the temperature of the water. You can do this by running hot water from a faucet and checking its temperature with a thermometer. The temperature of the water should be between 120 and 140 degrees fahrenheit.
Step 5: Adjust The Thermostat If Necessary
If the water temperature is not between 120 and 140 degrees fahrenheit, you will need to adjust the thermostat. The thermostat is also located on the front panel of the water heater. You can adjust the thermostat by using a flathead screwdriver to turn the adjustment screw.
Turn the screw clockwise to increase the temperature and counterclockwise to decrease the temperature. Make sure that you adjust the thermostat in small increments until the water temperature is between 120 and 140 degrees fahrenheit.
By following these quick and easy steps, you can reset your water heater and have it functioning again in no time.
