How To Fix:
If you just installed your AO Smith Electric Water Heater, it’s a typical problem that it doesn’t have any electricity. So, check the electricity to your unit first, and then the AO Smith water heater keeps tripping the reset button. Purchase a non-contact circuit tester and adhere to the advice provided below:
- At the circuit breaker, switch off your water heater.
- Take off the junction box’s cover. It is located on the top of the water heater’s top.
- It’s important to distinguish between the ground wire and the power cord. The color of the power cord is either red/black or black/black. On the other hand, the ground wire is green or copper wire.
Now, activate your circuit breaker and check the power on both incoming power lines using a non-contact circuit tester. Recover the lid for the electrical junction box and turn off the electricity.
If no electricity is coming to the appliance, immediately call a licensed electrician to inspect your home’s wiring and circuit breakers.
How To Reset Ao Smith Water Heater
- Go to your home’s electrical panel, either in the garage or on one of the building’s outer walls. Locate the breaker with the word “water heater” on it. Turn it so that it is “off.”

- To reset, click the water heater reset button. The water heater has been reset, and you should hear a clicking sound.
- To turn on the breaker switch, go back to the electrical panel.
