recently moved into a flat with the above boiler connected to an unvented hot water system. the system worked for a couple of weeks then nothing.
the code on the display said pcb needing replacing but it blew up too.......
£200 wasted.
I have checked resistance on the fan at 120ohms but the gas valve is 4000ohm, am I going mad or is it because there is no power on or is this the reason the pcb is blowing up.
any ideas please
