Common Lochinvar Water Heater Error Codes
Familiarity with error codes on your Lochinvar water heater helps you troubleshoot issues effectively. Here are the most common error codes you might encounter:
Error Code E1
Error Code E1 signals a faulty temperature sensor. This issue arises when the sensor fails to read the water temperature accurately. To address this code, first, inspect the wiring and connections for any damage or loose connections. If everything appears intact, replacing the temperature sensor resolves the issue.
Error Code E2
Error Code E2 indicates a high-temperature limit switch error. This error occurs when the water temperature exceeds the safe limit, potentially due to a malfunctioning thermostat or blocked vents. If you see this error, check the thermostat settings and the venting system for obstructions. Adjusting or repairing these components often eliminates this error.
Error Code E3
Error Code E3 points to a flame loss detection issue. The heater fails to detect the flame during operation, leading to a safety shutdown. This error often happens due to dirty burners or issues with the gas supply. First, inspect the burners for dirt and clean them if necessary. Also, ensure that the gas supply is steady. If problems persist, consulting a professional technician may be necessary.
