BoilerFaultCodesTechnical description
False flame.
What causes this fault?
This fault occurs when the boiler's control system detects a flame signal even though the burner hasn't been told to ignite yet. The most common reasons are a contaminated sensing electrode sending a false signal, a gas valve that is leaking slightly, or a glitch in the circuit board's electronics.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
