Replacing the drain valve in your US Craftmaster electric water heater

• Switch the two house circuit breakers dedicated for the water heater to OFF. Wear work gloves to protect your hands.
• Turn off the cold water supply to the water heater. Attach a garden hose to the drain valve located at the bottom of the unit and run the garden hose outside. Open a hot water faucet in the house or flip the relief valve open on the water heater. Open the drain valve and allow the tank to drain until empty.
• Remove the garden hose from the drain valve. Unthread and remove the drain valve from the tank.
• Wrap some thread-sealing tape around the threads of the new drain valve. Install the new drain valve and tighten firmly.
• Turn the cold water supply on to the water heater and allow the tank to fill with water. Once you see water coming out of the hot water faucet, turn the hot water faucet off. Flip the house circuit breakers to the ON position.

How to troubleshoot your US Craftmaster electric water heater when you're getting no hot water

Check both house circuit breakers for the water heater. Reset the circuit breakers by shutting them off and then flipping them back on. A gas water heater will have a single circuit breaker. Reset that circuit breaker the same way-shut it off and flip it back on.

If the electric water heater doesn't begin to heat after resetting the circuit breakers, shut the breakers off and press the reset button for the high-temperature limit switch on the upper thermostat of the water heater. If the water heater works for a while and then trips the high-temperature limit switch again, you'll likely need to replace a failed thermostat that's causing the element to heat constantly. If an electric water heater element doesn't heat when activated, replace the heating element. Replace the thermostat if it doesn't activate the heating element. Our no-hot-water troubleshooting video can help you figure out which part to replace in an electric water heater that's not heating.
