Common Navien Faults We Repair in Mission
Navien reports problems through E-prefix error codes (E003, E012…) shown on the front panel. These are the faults our technicians diagnose most often on Mission service calls:
- E003Ignition Failure
The unit attempts ignition three times and locks out — igniter wear, low gas pressure, a blocked gas valve, or a dirty flame rod. Damp Vancouver winters coating the electrode make this our most common Navien call.
- E012Flame Loss During Operation
The boiler lights but the flame drops mid-cycle — fluctuating gas pressure, a deteriorating gas valve, or combustion-chamber debris.
- E110Water Temperature Sensor Fault
The outlet sensor reads out of range — sometimes the sensor, often restricted primary-loop flow. We check zones and the circulator before replacing parts.
- E016Overheating (High Limit)
Unsafe temperature reached — blocked or air-locked heat exchanger, seized circulator, or excessive output demand. Needs same-day attention.
- Frozen Condensate Line
Exterior condensate runs freeze in cold snaps and lock the unit out until thawed and re-routed or insulated.
Navien Repair Cost in Mission
A diagnostic service fee applies and is credited toward the repair if you proceed. Typical repair ranges in BC:

|---|---|
| Igniter / flame-rod replacement | $165–$280 |
| Gas-valve replacement (E003/E012 root cause) | $360–$560 |

| Condensate repair / freeze protection | $150–$320 |
| Heat-exchanger descaling | $220–$320 |
We verify gas inlet pressure under full load on every Navien call — undersized or restricted gas supply masquerades as igniter failure more often than any other fault.
