Common Reasons Why Rheem Water Heater Stopped Working
Rheem water heaters may stop working for various reasons. Identifying these issues can help you restore hot water quickly.
Electrical Issues
Electrical issues often prevent a Rheem water heater from functioning. Check the following:
- Tripped Circuit Breakers: If the circuit breaker trips, reset it to see if that restores power.
- Blown Fuses: Inspect fuses in the electrical panel. Replace blown fuses if necessary.
- Faulty Thermostat: If the thermostat malfunctions, it may not signal the heating element. Test or replace the thermostat for proper function.
- Loose Wiring: Look for loose connections. Tightening any loose wires may resolve the issue.
Gas Supply Problems
Gas supply problems can lead to a lack of hot water in gas-powered Rheem water heaters. Consider these points:
- Closed Gas Valve: Ensure that the gas supply valve is open. If closed, open it to restore gas flow.
- Gas Leak: Check for gas leaks; listen for hissing sounds and smell for rotten eggs. If you suspect a leak, evacuate the area and contact a professional.
- Pilot Light Outage: If the pilot light is out, follow the manufacturer’s instructions to relight it. Ensure that you’re following safety guidelines during this process.
- Malfunctioning Gas Burner: If the burner isn’t working, it may require cleaning or replacement. Inspect the burner for debris or damage.
By addressing these common issues, you can diagnose and fix the problems causing your Rheem water heater to stop working efficiently.
Troubleshooting Steps for Rheem Water Heater
When your Rheem water heater stops working, you can take several troubleshooting steps to identify the issue and restore hot water.
Resetting the Heater
- Locate the Reset Button: Find the reset button on your water heater, usually near the thermostat.
- Press the Reset Button: Firmly press the button. A click sound may indicate the heater reset.
- Check the Power Source: Ensure the heater is plugged in and the circuit breaker hasn’t tripped. If it has, reset the breaker and try again.
- Access the Thermostat: Remove the access panel on the front of the heater.
- Verify the Temperature Setting: Set the thermostat to your desired temperature, typically between 120°F and 140°F.

By following these steps, you can troubleshoot your Rheem water heater effectively.
Maintenance Tips for Rheem Water Heaters
Maintaining your Rheem water heater helps ensure reliable performance and extends its lifespan. Here are some essential tips for keeping your unit in top condition.
Regular Inspections
Inspect your water heater at least once a year to identify any problems early. Check for signs of leaks around joints and connections. Look for rust or corrosion on the tank exterior. Investigate the pressure relief valve by lifting the lever and allowing a small amount of water to drain. It should release water without any obstruction. If you notice any irregularities, take action immediately to prevent major issues.
Flushing the Tank
Flushing your water heater tank removes sediment buildup, which can affect efficiency and water quality. Perform this task once every six months. To flush the tank, follow these steps:
- Turn off the power or gas supply: Switch off the circuit breaker for electric models or turn off the gas valve.
- Connect a hose: Attach a garden hose to the drain valve located at the bottom of the tank.
- Drain the tank: Open the drain valve and allow the water to flow out until it runs clear.
- Refill the tank: Close the drain valve, remove the hose, and turn the water supply back on. Once full, restore power or gas.
Flushing the tank improves efficiency and helps you avoid foul odors in the water.
When to Call a Professional
Recognizing when to seek professional assistance for your Rheem water heater is crucial. You should contact a qualified technician in the following situations:
- Persistent Issues: If you’ve followed troubleshooting steps without success, such as resetting the heater or adjusting the thermostat, it’s time to call a pro.
- Leakage: If you notice water pooling around your water heater, a leak may exist. This situation requires immediate attention to prevent further damage.
- Strange Noises: If your water heater makes unusual sounds like rumbling, popping, or hissing, these may indicate sediment buildup or mechanical problems needing professional evaluation.
- Fluctuating Temperatures: If your water temperature varies significantly despite adjustments, it may signal a malfunctioning thermostat or heating element that needs expert repair.
- Age of Unit: If your water heater is over 10 years old and experiencing issues, consider a professional inspection to determine if a replacement is necessary.
- Gas Supply Problems: If you suspect a gas leak or pilot light issues, prioritize safety and call a technician immediately. Do not attempt to diagnose gas-related problems yourself.
- Electrical Issues: If you face frequent tripped circuit breakers or blown fuses connected to the water heater, it indicates a deeper electrical problem. A professional will identify and resolve the issue safely.
By recognizing these signs, you ensure your Rheem water heater operates efficiently and safely.
