BoilerFaultCodesYour boiler is still detecting a flame even after it has told the gas to turn off, which is a safety conflict that causes the system to shut down.
Turn off your boiler and stop using gas appliances. Call a Gas Safe engineer now — this fault can be dangerous if ignored.

What causes this fault?
This fault occurs when the boiler's internal sensors continue to detect heat or an electrical signal from a flame even after the gas supply should have been cut off. The most common reason is a leaking gas valve that isn't closing fully, or a fault on the main circuit board that is misinterpreting signals from the burners.
