BoilerFaultCodesWhat the manual says
Manufacturer manualIgnition failure
What causes this fault?
This fault occurs when the boiler's control system attempts to start the combustion process but fails to detect a flame after several attempts. It is usually caused by a lack of gas supply, a worn-out ignition spark electrode that can no longer create a spark, or a faulty gas valve that isn't opening correctly.
While this can happen year-round, it often occurs during the first cold snap of winter when the gas valve may stick after being dormant during the summer months.
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.
