How to Troubleshoot a Rheem Water Heater

Rheem is highly recognized for providing top quality residential and commercial water heaters. They come in a wide range of sizes and capacities, are designed to deliver hot water quickly and are very energy efficient. Rheem water heaters are constructed to provide many years of operation. When problems do arise, it helps to perform some simple troubleshooting steps before calling a qualified repair person, saving you both time and money.

Not enough or no hot water

Step 1

Check the water usage in your home. If the usage has exceeded the capacity of the water heater, wait for the water heater to fully recover.

Step 2

Check the power supply to the water heater. Check to see if a fuse has blown or a circuit breaker is tripped. Replace the fuse or reset the breaker. Ensure that the disconnect switch, if used, is in the on position.

Step 3

Check that the water heater is receiving fuel, if it's a gas heater, by ensuring that any cutoff valves in the gas line are turned to the on position. Other gas water heater problems need to be serviced by a qualified service technician.

Step 4

Check the thermostat on the water heater for proper adjustment, and readjust the setting, if needed.

Step 5

Ensure that all faucets in the plumbing system are in good repair and are not leaking and closed.

Other problems

Step 1

Remove and clean the heating elements, if the water heater makes a rumbling noise. This is due to mineral scale that builds up on the elements.

Step 2

Contact a qualified plumber if the relief valve makes a popping sound or drains water. This is due to excessive pressure in the plumbing system.

Step 3

Adjust the thermostat on the water heater, if the water is coming out too hot.
