IDEAL FAULT CODE
Ideal L2
An ignition lockout — the boiler has failed to ignite, or ignited and failed to stay lit, and has locked out as a safety measure.
WHAT L2 TYPICALLY INDICATES
An ignition lockout — the boiler has failed to ignite, or ignited and failed to stay lit, and has locked out as a safety measure.
WHAT TO DO
There is no safe homeowner check for an ignition lockout. This is not a DIY fix — it requires a Gas Safe registered engineer to diagnose and repair safely.
A NOTE ON GAS SAFE REGISTRATION
Any work on the gas side of a boiler in the UK legally requires a Gas Safe registered engineer, it isn't optional. Our engineers are fully Gas Safe registered, and you're always welcome to ask to see ID on the day. This page is general information about what a fault code typically indicates; it is not a substitute for an engineer diagnosing your specific boiler.
