Technical description: Ignition failure / no flame detected
What causes this fault?
This fault occurs when the boiler tries to start but fails to detect a steady flame after several attempts. It is usually caused by a dirty ignition probe that cannot spark correctly, a lack of gas reaching the burner, or a faulty sensor that fails to tell the boiler that the flame is actually lit.
This issue is more frequent during the first cold snap of autumn, as internal components can stick or corrode after being idle throughout the summer months.
DIY fix possible
Check if other gas appliances, like a hob, are working to ensure gas is being supplied to the home.Ensure your gas meter has credit if you are on a pre-payment meter.Press the 'Reset' button on the front of the boiler once to see if the system restarts.
