I had a water leak and damaged the pcb had new master cylinder to cure leak and new pcb board and now it locks out when boiler turns on if u take the front cover off (to fan and boiler) it works fine. The corgi plumer has now replaced fan and the problem of it locking out is still there when u start up unless u leave the front cover off to the fan and boiler area. what do i do now. Is it a faulty board or my vertical air vent is blocked????.

he replaced fan, but did he remove and clean venturi`s?
venturios were replaced first and then replaced the hole fan unit with new venturios. on the old fan it seized up 6 months ago and he freed it but this did not lock out the boiler just did not come on. Why is it locking out now??????.
