Pensotti 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 Pensotti error E01
- No gas: gas valve on boiler or gas meter closed, or no gas in the mains/tank supply
- Broken, earthed, or fouled ignition electrode
- Gas valve malfunction or mechanical minimum set too low
- Ionisation/flame electrode malfunction or disconnected cable (flame present but not sensed)
- Obstructed inlet/outlet flue pipes or excessive LPG inlet pressure
What you can safely check
- Confirm the gas supply is on (gas meter/cylinder valve and the boiler gas cock both open) and other gas appliances work
- Check system pressure on the gauge is at least 1 bar
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 E01 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 Pensotti repair.
