Common Navien Tankless Water Heater Issues in Carlsbad
Navien systems are advanced, high-efficiency units — but they require proper maintenance and accurate diagnostics. We regularly repair:
- No hot water or inconsistent temperature
- Navien error codes (E003, E012, E110, E351, etc.)
- Flame loss or ignition failure
- Mineral scaling from hard water
- Heat exchanger leaks
- Recirculation pump failures
- Condensate drain blockages
- Venting and combustion air issues
Carlsbad’s mineral content can accelerate scale buildup inside tankless heat exchangers. Annual flushing is critical to prevent premature failure.
