Rinnai fault codes can vary slightly by model and series. Use this as a guide — the same code can have more than one cause. Our Technical Safety BC–licensed technicians read the code, confirm it against your unit's manual, and diagnose the true cause before any repair.
Likely causes of Rinnai error 10
- Blocked or obstructed flue/vent terminal
- Too long or incorrectly installed venting
- Failing combustion fan
- Debris, snow or nests at the termination
What you can safely check
- Check the outside vent terminal is clear of snow, leaves or debris
- Make sure nothing is blocking the intake/exhaust
- Note any wind/weather link
Beyond these checks, do not open the unit or touch gas/electrical parts — BC law requires a licensed gas fitter. Call us for a proper diagnosis.
