IT WOULD APPEAR THAT THERE IS NO POWER TO BOILER BUT WHEN I TEST IT WITH A MULTI METER ITS GETTING POWER UP TO SWITCH BUT NOT SURE WHAT HAPPENS AFTER THAT IS IT THE PCB OR THE THERMOSTAT CONTROL HOUSING THATS AT FAULT?
I had the same problem 2 days ago, I had system repair cover taken out.. in that repair they replaced main PCB unit, in 5 minutes back in to action...! I would suggest that with morden appliences, service and repair cover shuld be considered or will face expensive repairs.
