What LC means
LC indicates 5 boiler resets in 15 minutes.
Gas Safe engineer: If the message remains or returns after one restart, contact a Gas Safe registered engineer.
A boiler fault code alone is not a gas or carbon-monoxide emergency. If you smell gas, a CO alarm sounds, anyone feels unwell, or there is an unsafe flame, leave and call 0800 111 999 from outside.
Renting? Report it to your landlord or housing provider first. They are responsible for gas safety and boiler repairs, and the repair should not cost you.
Safe check
Turn the boiler electrical supply off and back on once using its normal external switch.
When to contact an engineer
If the message remains or returns after one restart, contact a Gas Safe registered engineer.
