BoilerFaultCodesYour boiler has detected a flame even though it hasn't signaled for the burner to light, which is a safety conflict that prevents it from running.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: All Boilers
What causes this fault?
This fault occurs when the boiler's internal sensors detect a flame after the heating cycle has finished or before it has even started. The most common reasons are a gas valve that is leaking fuel into the burner when it should be closed, or a sensing probe that is sending a false signal to the control board.
