Likely causes of Rinnai error 11
- Gas supply off or low pressure
- Faulty igniter or ignition electrode
- Failed ignition control
- Gas valve fault
What you can safely check
- Confirm the gas is on (other gas appliances work)

- Note if it clicks when trying to start
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.
