Your boiler has tried to light several times but cannot establish a flame, meaning your heating and hot water will not work until it is reset or repaired.

DIY fix possible

Check if your gas supply is turned on at the meter or if other gas appliances are working.If you have a prepaid gas meter, ensure it has sufficient credit.Press and hold the 'Reset' button for five seconds to see if the boiler restarts.Check that the white plastic condensate pipe outside hasn't frozen during cold weather.
