Common Rinnai Faults We Repair in Coquitlam
Rinnai reports problems through numeric fault codes (10, 11, 12…) shown on the control panel or wired remote. These are the faults our technicians diagnose most often on Coquitlam service calls:
- 11No Ignition / No Flame Sensed
The burner fails to light after repeated attempts and the unit locks out. Common root causes are a worn igniter or flame rod, low gas inlet pressure under load, or a gas valve no longer delivering a consistent fuel-air mix. The single most frequent Rinnai service call in Metro Vancouver.
- 12Flame Failure During Operation
The flame lights but drops out mid-cycle. Typically a dirty or degraded flame rod, fluctuating gas supply, or combustion air starvation. Repeated 12 lockouts cause short-cycling that accelerates wear on the ignition system and heat exchanger.
- 10Air-Supply or Exhaust Blockage
The unit detects restricted intake or exhaust flow — debris at the termination, a sagging flue run, or recirculating exhaust gases. In coastal BC, wind-driven rain and debris at sidewall terminations are frequent winter culprits.
- 25Condensate Drain Fault
Condensate is not draining freely — a blocked trap, frozen external drain line, or failed condensate pump. Common during Lower Mainland cold snaps when condensate lines run through unheated spaces.
- 14Thermal Fuse / Overheat
The high-temperature safety has tripped. Usually scale buildup in the heat exchanger, restricted system flow, or a failing circulator. Requires professional diagnosis — repeated resets risk permanent heat-exchanger damage.
Rinnai Repair Cost in Coquitlam
A diagnostic service fee applies to all Rinnai repair calls and is credited toward the repair if you proceed. Typical Rinnai repair ranges in BC:
| Repair | Typical range (CAD) |
|---|---|
| Igniter / flame-rod replacement | $175–$300 |
| Gas-valve replacement (11/12 root cause) | $380–$580 |
| Condensate trap or drain repair (code 25) | $150–$320 |
| Venting correction (code 10 root cause) | $250–$600 |
| Heat-exchanger chemical descaling | $220–$320 |
We verify gas inlet pressure under full load and check post-repair combustion values against Rinnai spec — the two most common root causes behind repeat code 11 and 12 lockouts.
