Raypak fault codes can vary 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 Raypak error ILO
- Repeated failed ignition attempts
- Faulty or contaminated pilot/igniter assembly
- Insufficient or interrupted gas supply
- Ignition control board fault
- Weak spark or grounding problem
What you can safely check
- Verify gas is supplied to the home and other gas appliances run normally
- Confirm the gas valve serving the boiler is open
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.
Error ILO usually leaves you without heat or hot water and can indicate a safety-related fault. Don't keep resetting it — call for priority after-hours Raypak repair.
