BoilerFaultCodesYour boiler has tried to light several times but has been unable to establish or maintain a flame, so it has shut down for safety.
Book a Gas Safe engineer within 24–48 hours. Your boiler may be unsafe or could break down completely if left.
Technical description: Ignition failure: Should the flame not ignite or is unstable within the pre-set safety time cycle the controls will shut the boiler down (after 5 attempts)
What causes this fault?
This fault occurs when the boiler's control system fails to detect a stable flame after several attempts to fire up. The most common reasons include a lack of gas reaching the burner, a worn-out spark electrode that can no longer create a spark, or a dirty internal sensor that cannot 'see' the flame even if it has lit.
This fault can be more frequent during extreme cold spells if the external gas regulator or pipework freezes, restricting the flow of fuel required for ignition.
DIY fix possible
Check if other gas appliances, like a cooker, are working to ensure gas is being supplied to the property.Verify that your gas meter has credit if you use a pre-payment meter.Reset the boiler by pressing the 'Reset' button for a few seconds to see if it clears the lockout.
