BoilerFaultCodesYour boiler is currently trying to light the gas burner and is showing a normal status light while it generates an ignition spark.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Flashes to indicate spark operation (stops after detection)
What causes this fault?
This occurs when the boiler is actively attempting to light the gas burner to provide heating or hot water. The light flashes while the ignition system generates a spark, which should then stop once the boiler detects a successful flame. If the light continues to flash without the boiler firing up, it usually means the gas isn't reaching the burner or the spark isn't strong enough to ignite it.
DIY fix possible
Check if your gas supply is turned on at the meterPress the reset button if the light continues to flash without the boiler firing upEnsure there is enough credit on your pre-payment gas meter if applicable
