Error Code 003: Navien Tankless Water Heater
Encountering Error Code 003 on your Navien Tankless Water Heater can be quite frustrating, but fear not, as I’m here to guide you through troubleshooting this issue. This error code typically indicates a flow sensor issue, which means there may be a disruption in the water flow or a problem with the sensor itself.
One of the first things I recommend checking is the water inlet filter to ensure it is not clogged or blocked. A dirty filter can impede water flow and trigger Error Code 003 on your Navien unit. Cleaning or replacing the filter might resolve the issue promptly.
If the filter appears to be in good condition, you can also inspect the flow sensor for any visible damage or loose connections. Sometimes, a simple adjustment or tightening of the sensor can clear the error code.

In some cases, restarting the unit by powering it off and on again after addressing the potential causes mentioned above can reset the system and clear the error code.
