BoilerFaultCodesYour boiler is currently trying to light the flame and this light will turn off as soon as the burner is successfully lit.
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 ignition operation (stops after detection).
What causes this fault?
This status occurs when the boiler's control board sends an electrical signal to the spark generator to begin the combustion process. It indicates that the system is functioning as intended by attempting to create a flame, and the light should disappear once the internal sensors detect that the burner is successfully lit. If the light persists or flashes repeatedly without the boiler firing up, it usually suggests an issue with the gas supply or a worn-out ignition electrode.
DIY fix possible
Check if the boiler stays lit after the flashing stopsMonitor for any lockout lights if the flame fails to igniteEnsure your gas supply is turned on at the meter
