If troubleshooting doesn’t resolve the issue, contact a licensed technician. Persistent problems with the heating system or recurring error codes often require expert intervention.
Common Error Codes and Their Meanings
Understanding error codes on your Reliance water heater helps resolve issues quickly. Below are common error codes and their meanings to assist in troubleshooting.
Code E1: Ignition Failure
Code E1 indicates an ignition failure. This means the burner failed to light, which can happen for several reasons. Check the following:
- Gas Supply: Ensure the gas valve is open.
- Pilot Light: Confirm the pilot light is lit.
- Connections: Examine gas connections for blockages or leaks.
If these steps don’t resolve the issue, it’s advisable to consult a technician.
Code E2: Over Heating
Code E2 signals overheating in the water heater. This occurs when the water temperature exceeds safe levels. To troubleshoot:
- Thermostat Setting: Check if the thermostat is set too high. Adjust it to a safer temperature, typically around 120°F.
- Faulty Thermostat: Inspect the thermostat for damage or malfunction.
If the issue persists, professional service may be required to replace faulty components.
Code E3: Temperature Sensor Issue
Code E3 indicates a problem with the temperature sensor. This sensor monitors water temperatures to ensure proper heating. To address this issue:
- Wiring Connections: Inspect wiring for loose or damaged connections.
- Sensor Replacement: If connections are secure, the temperature sensor may require replacement.
Always ensure power is turned off before attempting repairs. If uncertain, contacting a professional ends concerns over safety and effectiveness.
Troubleshooting Reliance Water Heater Error Codes
Troubleshooting Reliance water heater error codes can restore your hot water and prevent future frustrations. Follow these steps to address common issues effectively.
Step-by-Step Troubleshooting Process
- Identify the Error Code: Start by looking at the error code displayed on the control panel. Write it down for reference.
- Consult the Manual: Refer to the user manual specific to your model for detailed descriptions of error codes and suggested solutions.
- Check Connections: Inspect gas and water line connections. Ensure they are secure and free from leaks, as loose connections can trigger faults.

- Physical Damage: Signs of corrosion, leaks, or electrical wear indicate a need for professional assessment.
- Safety Concerns: If you’re unsure about your ability to conduct repairs safely, professional assistance is best.
- Complex Issues: Complicated problems such as gas line repairs or internal component failures require licensed technicians for safety and compliance.
Relying on professionals ensures safe and effective resolutions to issues that could lead to bigger problems.
Preventative Maintenance Tips
Regular maintenance keeps your Reliance water heater running smoothly and helps prevent error codes. Implement these effective tips for optimal performance.
Regular Inspections
Check your water heater every six months. Look for leaks around connections, rust, and unusual noises. Ensure that the venting system is clear of obstructions. Examine the relief valve by lifting the test lever briefly to allow some water to escape. This simple check helps confirm the valve functions properly. If you notice any irregularities, it’s smart to consult a professional for further inspection.
Flushing the Tank
Flush your water heater annually to remove sediment buildup. Start by turning off the power and closing the cold-water supply valve. Attach a garden hose to the drain valve at the bottom of the tank. Place the other end of the hose in a suitable drainage location. Open the drain valve, allowing water to flow out until it runs clear. Close the drain valve and remove the hose. Reopen the cold-water supply valve and restore power to the unit. This process helps improve heating efficiency and prolongs the tank’s lifespan.
