Water Heater Stopped Working
Electrical Question: Why is my water heater not working?
Amanda, a Homeowner in Kentucky asks:
- We recently replaced our entire water line up to our home, beforehand we turned the electric off to the water heater from the break box.
- After the water was hooked back up and we purged the line of air and the water was turned on all the way we turned the breaker back on to the water heater. However, since doing so we don’t have hot water.
- We’re getting electric to the water heater just fine. We just recently purchased the water heater.
John, a Handyman, in Florida asks:
- I have a new water heater that is not working.
- This is a older home that had no ground wire to electric water heater.
- I had a new heater installed and ran a ground wire to a rod. Still no hot water.
- I checked everything per the water heater trouble guide.
- I am getting 120volts on each leg but nothing on both legs together.
- Do I have a bad breaker?
- The previous water heater was working without ground.
Additional Comments: Extremely helpful for those of us trying to identify problems to better help our electrician (and to save money if it is a simple fix.)

How to Fix a Water Heater Problem
This information is about a Water Heater that is not working in a residential home.
For Amanda in Kentucky:
Water Heater is Not Working after Replacing the Water Line
- Test the new water line to make sure there are no obstructions and the water pressure and water flow is normal.
- Before restoring power to the water heater, make sure the water heater tank is completely full of water.
- Make sure to bleed off any excess air that may be trapped inside the water heater tank.
- The pressure relief valve of the water heater could be tested to see if water is flowing and there is no trapped air inside the tank. NOTE: This should be done only if there is a continuous drain line attached to the pressure relief valve that leads outside of the home.
- Test the flow of water at a sink or bath tub to make sure water is flowing from the hot water side of the facets.
For John in Florida:
Water Heater is Not Working after Replacing It
- Since the previous 240volt water heater was working before, then I suspect the circuit breaker is either partially tripped off, or the connection of the breaker to the panel is faulty, or the circuit breaker needs to be replaced.
- Important: The main electrical system should be properly grounded. If the main panel did not have a ground system in place then the ground rod should have been properly installed at the main electrical panel, and then a ground wire should be installed from the main panel to the water heater.
