Technical description: Ignition lockout error
What causes this fault?
This fault occurs when the boiler's control system attempts to light the burner multiple times but fails to detect a stable flame. The most common reasons include a worn-out ignition spark, a faulty gas valve that isn't opening properly, or an issue with the sensor that confirms the fire is actually lit.
This issue is slightly more frequent in winter as cold weather can affect gas pressure and put older, struggling ignition components under more strain.
DIY fix possible
Check that your gas emergency control valve is open and you have credit on your meterPress the reset button or turn the control knob to 'O' and back to 'I'Check if other gas appliances in your home, like a hob, are working correctly
