Today of all days it decides to turn off just when the home emergency cover has expired. Anyway the fault is that when i turn the heating or hot water switch the bolier turns on and off continuously, the boiler light is on, Fan light comes on and then goes out. Pilot and burner lights do not turn on at all. The bolier is stuck in some sort of loop, where it turns on and off as i can hear the boiler trying to turn on.
