What does the Ideal F1 error code mean?
F1 on an Ideal Logic / Logic+ / Vogue boiler is ignition lockout. The boiler tried to ignite and failed. Like other ignition faults, check the gas supply first, then call an engineer if gas is fine.
What causes the Ideal F1 fault?
The F1 error on a Ideal boiler is most commonly triggered by:
- No or low gas supply (check the meter and prepayment credit)
- Dirty or worn ignition electrode
- Blocked or frozen flue / condensate in cold weather
- A failing gas valve

Frequently asked questions about the Ideal F1
What does F1 mean on an Ideal boiler?
F1 is ignition lockout — the boiler tried to light and couldn't. It's usually a gas supply, ignition electrode or flue/condensate fault.
Can I fix an Ideal F1 myself?
Check the gas supply by testing another appliance and that your prepayment meter has credit. Beyond that, F1 is a gas-related fault that needs a Gas Safe engineer.
