What causes this fault?
This fault occurs when the boiler's control system attempts to start the burner but fails to detect a flame after several attempts. The most common reasons include a lack of gas reaching the appliance, a soot-covered ignition lead that cannot produce a spark, or a faulty gas valve that isn't opening properly.
This issue is more frequent during the first cold snap of autumn when internal components that have been idle all summer suddenly seize or fail under load.
