BoilerFaultCodesYour boiler thinks a flame is burning even though the gas should be turned off, which causes it to shut down for safety.
Turn off your boiler and stop using gas appliances. Call a Gas Safe engineer now — this fault can be dangerous if ignored.
Technical description: Flame detected when gas valve off (false flame)
What causes this fault?
This fault occurs when the boiler's sensors detect a flame after the heating cycle has finished and the gas should be stopped. The most common reason is a component failure, such as a sticking gas valve that is letting tiny amounts of fuel through or a faulty sensor that is incorrectly reporting heat to the main control board.
