BoilerFaultCodesTechnical description
false flame
What causes this fault?
This fault occurs when the boiler's sensors detect an electrical current that mimics a flame, even though the gas hasn't been turned on yet. This is usually caused by a dirty or damaged detection probe sending a false signal, or a fault within the main control board that misinterprets electrical background noise as a fire.
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.
