BoilerFaultCodesTechnical description
Flame failure
What causes this fault?
This fault occurs when the boiler's control board fails to detect a flame after several attempts to fire up. The most common reasons are a lack of gas reaching the burner, dirty internal probes that can no longer 'see' the flame, or a faulty ignition lead that isn't providing the spark needed to start the combustion process.
This fault often appears during the first cold snap of autumn when a boiler that has been idle all summer is suddenly forced to work at high capacity.
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.
