Frequently Asked Questions

Answers to common Navien operational and troubleshooting questions

Error E003 indicates an ignition failure, while E110 points to an abnormal exhaust or intake condition. First, verify your gas supply valve is fully open and check that the external vent terminations are free of debris or ice. If the error continues, power off the unit and call our 24/7 technicians to safely diagnose the gas valve, flame sensor, or pressure switch.
