Common Navien Problems We Fix

Navien error code 10 indicates restricted or blocked exhaust venting. In LA, this is often caused by bird nests, debris, or improper vent termination. Our technicians inspect and clear the vent path and retest combustion.

Los Angeles hard water causes scale to accumulate in the Navien heat exchanger over time. Code 27 (or persistent low flow issues) often indicates descaling is needed. We flush the heat exchanger and test flow rates.

Navien error code 3 means the unit attempted to ignite but failed. Common causes include gas supply issues, a faulty igniter, or a dirty flame rod. We diagnose and replace components as needed.

Navien units with the built-in recirculation pump can develop flow sensor or pump failures that result in inconsistent hot water delivery. We diagnose the full recirculation system.

Condensing Navien units produce condensate that must drain freely. A blocked condensate line causes shutdowns. We inspect, clear, and properly route condensate drainage.

Navien Models We Service

Frequently Asked Questions

To reset a Navien tankless water heater, press and hold the power button for 3 seconds until the unit shuts off, then press it again to restart. If an error code reappears after reset, the underlying issue needs diagnosis by a technician.

Navien error code 10 indicates an exhaust or intake blockage. Check that the vent termination on the exterior of your home is clear of debris, bird nests, or obstructions. If the vent appears clear, call us — the issue may be inside the venting run.

Navien recommends annual maintenance. In Los Angeles specifically, the hard water means annual descaling is important to prevent heat exchanger damage. We offer Navien maintenance service throughout the San Fernando Valley and greater LA.

Yes. We service the Navien NCB series combination boiler/water heaters in addition to standard tankless units. Combi boiler issues often involve the space heating circuit or domestic hot water priority settings.
