How to Repair an Electric Water Heater: 7 Common Problems.

No water or cold water: The water heater could be completely drained of water.

Short cycling: This is when the water temperature rises to the set temperature and then quickly drops back down to cold water.

Leaking water: If water is leaking from the water heater, turn off the water heater or contact a professional immediately.

Electrical wiring problems: Check electrical connections outside your home near the water heater pipe connections to make sure everything is secure.

Temperature water that is below the minimum setting: The water heater needs to be reset to the factory setting. Make sure water temperatures are set correctly after the water heater has been restarted.

High water temperature: This means water is set too high and water needs to be reset to the factory setting. Make sure water temperatures are set correctly after the water heater has been restarted.

Rusty water: This means that the water heater is rusting through or there are other water supply problems.

No water or cold water when the tank is heating.

This could be due to an error code, lack of power, a malfunctioning circuit board, or faulty/disconnected wiring. The first step would be to turn off the water heater and check all connections before troubleshooting any error codes. If no connections are found, call in a professional.

Short cycling

This happens when the water temperature rises above the set temperature and quickly drops back down to cold water. It’s crucial not to ignore short cycling because it can lead to premature failure of your water heater components which can result in electric shock, leaks, fires, water damage, and water contamination. If water is short cycling on a consistent basis it’s best to contact a professional for service.

Leaking water

If water is leaking from the water heater, turn off the water heater or contact a professional immediately. When you call your local plumber or HVAC technician, make sure to ask them if they provide water heater repair services. That way you can hire someone who specializes in what they do.

Electrical wiring problems

Check electrical connections outside your home near the water heater pipe connections to make sure everything is secure. Check for broken wires and make sure all wire nuts are securely fastened together. Water heaters operate at 240 volts so there must be four wires going to it – two black and two red.

Temperature water that is below the minimum setting

The water heater needs to be reset to the factory setting. Make sure water temperatures are set correctly after the water heater has been restarted. For propane water heaters, make sure both pilot lights (if applicable) come on when resetting water temperature and heating water again.

High water temperature

This means water is set too high and water needs to be reset to the factory setting. Make sure water temperatures are set correctly after the water heater has been restarted. For propane water heaters, make sure both pilot lights (if applicable) come on when resetting water temperature and heating water again. Make sure the thermocouple isn’t defective by completing the water heater repair thermometer test.

Rusty water

This means that the water heater is rusting through or there are other water supply problems. Set up an appointment with a licensed plumber and water treatment specialist to get your water tested and discuss your options. You should also check for possible leaks and clogs in both the hot and cold water lines while you’re at it.
