I have a problem with a potterton performa 24 eco he I've been though the fault finding and still can't find the problem. It is coming on, the fan is running the, air pressure switch is making, the pump is running, the pressure differential is working and triggering the micro switch but it fires for around 10 sec then stops in the 10sec the ignition is still sparking but the burner on light doesn't come on. It does this 3 time then goes to flame fault.
I've so far changed the heat sensing electrode, PCB and igniter/gas valve cable but it still not working!!
Could any one shed any light on it for me any help would be appreciated!!
