Understanding The E3 Error Code
The E3 error code indicates a problem with your Furrion tankless water heater. It typically points to issues that disrupt the flow of hot water, leading to unexpected cold showers.
What Causes The E3 Error Code?
- Blocked Air Intake: A blockage in the air intake can restrict proper airflow, triggering the E3 error. Check for any obstructions or debris.
- Overheating: If the unit overheats, safety mechanisms activate, displaying the E3 error. Ensure the heater has proper clearance and ventilation.
- Faulty Sensors: Malfunctioning temperature or flow sensors can send incorrect readings, resulting in the error code. Inspect sensors for damage or misalignment.
- Low Water Flow: Insufficient water pressure or flow can cause the heater to shut down. Verify that all valves are fully open and water supply is adequate.
- Electrical Issues: Problems with electrical connections or power supply can trigger the E3 error. Check for loose wiring or tripped breakers.
- No Hot Water: The most obvious symptom is the lack of hot water, often experienced during showers or other uses.
- Intermittent Cold Water: You may notice that hot water is available at times but suddenly turns cold. This fluctuation often coincides with the E3 error.
- Error Code Display: The E3 code will appear on the digital display of the water heater, signaling the need for troubleshooting.
- Increased Water Temperature: In some cases, the water temperature may exceed normal levels before the error occurs, indicating potential overheating.
- Unusual Noises: Bubbling, gurgling, or other unusual sounds may indicate issues within the unit, leading to the E3 code.
By understanding these causes and symptoms, you can take the right steps to troubleshoot the E3 error code and restore your hot water supply effectively.
Troubleshooting The E3 Error Code
When your Furrion tankless water heater displays the E3 error code, it indicates an issue that disrupts hot water flow. Here’s how to troubleshoot effectively.
