BoilerFaultCodesThis light is showing you that the boiler is currently trying to light the burner and is a normal part of the startup process.
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 light activates because the boiler's control box has sent a signal to create a spark and open the gas valve. It is a natural part of the start-up sequence and simply shows the system is working to establish a flame. Once the internal sensors detect that the burner is safely lit, the light will turn off automatically.
DIY fix possible
Check if the light stops flashing once the boiler has fired upEnsure your gas supply is turned on if the boiler fails to lightMonitor the boiler to ensure it transitions to a steady light or turns off correctly after heating
