A Rheem water heater that keeps turning off usually has issues with the thermostat or the pilot light. Regular maintenance can help prevent this problem.
Rheem water heaters are known for their reliability, but they can encounter issues over time. One common problem is the heater turning off unexpectedly. This issue can be frustrating and inconvenient, especially during colder months. The primary culprits are often a faulty thermostat or a malfunctioning pilot light.
Ensuring regular maintenance and timely repairs can keep your water heater functioning efficiently. Understanding the root causes and addressing them promptly will save you time and prevent further complications.

Common Issues
The pilot light often goes out due to gas supply issues. Dirt or debris can block the pilot orifice. Check for loose connections or a faulty thermocouple. Sometimes, a draft can blow out the pilot light. A weak flame can also cause the pilot to go out.
A malfunctioning thermostat can cause the water heater to turn off. The thermostat may not correctly read the water temperature. Wiring issues can also disrupt the thermostat’s function. A defective thermostat might need replacement. Incorrect settings could lead to frequent shutdowns.

Safety Precautions
Ensure the area around your Rheem water heater is clear of flammable materials. Check for gas leaks and secure all connections. Regularly inspect the pilot light and thermocouple for proper functioning.
Shutting Off Power
Turn off the power to your Rheem water heater. This prevents electrical shock. Locate the circuit breaker that controls the heater. Switch it to the “off” position. Remove the power cord from the socket if it is a plug-in model. Double-check that the heater is not receiving power. Safety should always come first.
Ensuring Ventilation
Proper ventilation is crucial. Ensure the area around the heater is clear. Remove any obstructions that could block airflow. Good ventilation prevents overheating. Check the vents to make sure they are open. Blocked vents can cause the heater to shut off.
Checking The Pilot Light
Inspecting the pilot light on your Rheem water heater can help identify why it keeps turning off. Ensure the flame is steady and blue, not flickering or yellow.
Relighting The Pilot
The pilot light must be on for the heater to work. Locate the gas valve and turn it to the “Off” position. Wait for five minutes to let any gas clear out. Turn the valve to “Pilot” and press down the reset button. Use a lighter to relight the pilot. Hold the reset button for a few seconds. Release the button and turn the valve to “On”. The pilot should stay lit now.
Inspecting The Flame
The pilot flame should be blue and steady. A yellow or flickering flame means there is a problem. Check for dirt or debris in the pilot tube. Clean it with a small brush or compressed air. Ensure the gas supply is not blocked. If the flame is still not right, call a professional.
Thermocouple Inspection
A faulty thermocouple can cause the water heater to turn off. Check if the pilot light is out. If it is, the thermocouple might be the issue. This small device senses the pilot light. If it fails, the gas valve will shut off. Look for any signs of damage or wear on the thermocouple. Ensure it is positioned correctly next to the pilot light. A bent or dirty thermocouple can also cause issues. Clean it gently using sandpaper.
Replacing the thermocouple is simple. Turn off the gas supply first. Unscrew the thermocouple from the gas valve and the pilot light. Remove the old thermocouple carefully. Install the new thermocouple in the same position. Tighten the screws firmly but not too tight. Turn the gas back on and light the pilot light. Watch the pilot light to ensure it stays lit. If it does, the replacement was successful.
Thermostat Settings
Set the thermostat to the desired temperature. Make sure it is not set too low. Low settings can cause the water heater to turn off. Turn the dial slowly to adjust the temperature. Check the manufacturer’s guide for the ideal setting. Always use caution to avoid scalding temperatures. Higher settings can also waste energy.
Test the thermostat to ensure it works properly. Use a thermometer to check water temperature. Compare it with the thermostat setting. If there is a big difference, the thermostat might be faulty. Reset the thermostat if needed. Sometimes, a simple reset can fix the issue. Replace the thermostat if it continues to malfunction. Faulty thermostats can cause the water heater to turn off.
Sediment Build-up
Sediment build-up in a Rheem water heater can cause the unit to keep turning off unexpectedly. Regular maintenance helps prevent this issue, ensuring efficient operation.
Flushing The Tank
Sediment can cause many problems in water heaters. Flushing the tank helps remove this sediment. Start by turning off the heater and letting it cool. Connect a hose to the drain valve. Open the valve and let the water flow out. This will push out the sediment. Close the valve and remove the hose. Fill the tank with fresh water. This simple task can improve your heater’s performance.
Preventing Future Build-up
Regular maintenance is key to preventing sediment build-up. Check your water heater every few months. Use a water softener if your water is hard. This helps reduce the minerals that cause sediment. Flushing the tank once a year is also a good practice. These steps will keep your water heater running smoothly.
Gas Supply Issues
The gas line needs to be checked for any blockages. Ensure there are no leaks or damages in the line. A blocked gas line can cause the heater to turn off. You can use a simple soap and water solution. Apply it to the gas line and check for bubbles. If you see bubbles, there is a leak. Fixing the gas line can solve the issue.
If the gas line is clear, contact your gas provider. They can check if there are any supply issues. Sometimes, gas supply problems can cause the heater to turn off. The provider can send a technician to inspect your gas meter. They will ensure the gas flow is steady and sufficient. This can help your heater run smoothly.
