hi all , had a strange one this morning, boiler just went off ,dead no lights nothing. checked electric no power cuts everything else on in house, tools out then first checked power to spur , on, checked power from spur, on , switched off at spur removed cover to boiler (intergas 24/28) ,pulled the pcb/controll panel forwards wiring looked all ok switched on at spur boiler fired and all lights on panel, had not touched a thing.
put it all back as is and still working .
Im not a heating eng but worked building maintenence for last 35 years so not a complete idiot but this has me stumped.
anyone got any ideas?
just seems strange the only thing that goes off is the boiler and switching it off at mains cures it.
thanks for looking
 
latest boiler been working all day no probs, checked time and noticed it had lost two hours over the course of six hours, is this an indicator that my pcb is on the way out, is there a reset button?
