What causes this fault?
This fault occurs when the boiler's control system attempts to start the heating process but cannot verify that a safe, stable flame has been established. The most common reasons are a lack of gas reaching the burner, dirty or worn electrodes that can't create a spark, or a failing internal component that cannot sense the flame correctly.
