BoilerFaultCodesTechnical description
Ignition failure
What causes this fault?
This fault occurs when the boiler has tried to ignite several times but cannot establish a stable flame to start the heating process. The most common reasons are a lack of gas reaching the burner, worn-out spark electrodes that can no longer create a light, or a faulty sensor that fails to 'see' the flame once it has started.
This fault can be more common during extreme cold spells if the external gas regulator freezes or if moisture in the gas line restricts flow.
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.
