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.
