Mastering Navien Error Codes: Your Guide to Tankless Water Heaters

Update Understanding Navien Tankless Water Heater Error Codes For homeowners who rely on tankless water heaters, understanding the common error codes is essential for maintaining comfort and efficiency. Navien water heaters are known for their reliability, yet problems can arise. This guide aims to decode these error messages, empowering you to troubleshoot and maintain your system effectively. Common Error Codes and Their Fixes Let's dive into some of the prevalent error codes associated with Navien tankless water heaters and how to resolve them quickly. Error Code E001: Water Overheating This code signals overheating in the heat exchanger, often due to an obstruction. To fix it, start by cleaning the inlet water strainer, ensuring it's free from debris. Next, check the automatic flow sensor, and if necessary, clean the heat exchanger itself. If the problem persists, the PCB board might need replacement. Error Code E002: Low Water Pressure If you encounter this issue, it's typically resolved automatically once the water supply stabilizes. In some cases, you may need to wait for a reset. Error Code E003: Ignition Failure This error indicates a failure in igniter sparks. Begin by verifying that the main gas supply is unobstructed, the power is on, and inspect the igniter itself. Addressing these components should resolve the issue. Error Code E004: Flame Incorrectly Detected When there's a detection of the wrong flame, checking the ground wire is essential. Ensure it's securely attached and inspect the igniter for correct sparking. Error Code E007: Hot Water Outlet Issues This code indicates a thermistor problem. Inspect the thermistor and replace it if necessary to restore normal function. Error Code E009: Fan Motor Malfunction Issues with the fan motor often trigger this code. Clean the air filter and check the fan motor for functionality. If the motor isn't operational despite sufficient voltage, consider replacing it. Error Code E010: Air Pressure Problems This error is tied to incorrect air pressure. Inspect the vent pipe and ensure it's clear of obstructions. If issues arise from the air pressure flow sensor, replacing it might be necessary. Error Code E011: High Water Pressure Detection In cases of high water pressure, inspect the pressure sensor; it should reset automatically. If not, a manual reset will be necessary.
