Boiler was not responding to either of the hot water or htg boiler stats,consequently it was overheating and blowing the prv and going off on high limit.
On advise i changed the micro switch on diverter valve and checked all electrical connections, unfortunately same thing happened.
I've dissconnected both thermistor connections and the boiler is still coming on. ITS ALIVE ALIVE.
Im of the opinion the pcb is the only thing left, can anyone put me out of my misery pleeeeaaasssseee.
ps the neon doesn't come on when boiler fires up and i know it does work.
