BoilerFaultCodesTechnical description
Ignition failure
What causes this fault?
This fault occurs when the boiler's control system attempts to light the burner but fails to detect a stable flame after several attempts. The most common reasons are a lack of gas reaching the unit, a worn-out ignition spark plug, or a fault within the internal gas valve that prevents the fuel from flowing correctly.
This code can appear more frequently during the first cold snap of winter if the gas supply has been inactive or if external gas regulators have been affected by the drop in temperature.
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.
