BoilerFaultCodesYour boiler incorrectly thinks it sees a flame before it has even started the ignition process, which is a safety error that prevents it from starting up.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: Contact Installer
What causes this fault?
This fault occurs when the boiler's control system detects an electrical signal suggesting a flame is already present before the gas has been turned on. The most common reason is a carbon build-up or moisture on the sensing electrode causing a false reading, or a communication error within the main circuit board.
