Guys, got a worcester 9.24 (47-311-07) with the old relay and 1 circuit board, not the one with 2 boards !!
The problem im advised is intermitting, the boiler will not always fire on demand for central heating, but if the customer runs the hot water this activates the boiler and the c/h stays on after tap is run, went to this today and it worked ok, at first it didnt and had to do as customer did but only done this once and couldnt find any faults ??
anyone else had this or can advise ?? initial thoughts were pcb or the relay but more swaying to the pcb, possibly a stickingrelay in the main pcb ??
did notice also that the molex connector to the c/h selector knob was disconnected but customer has advised this fault only started recently and no one has been at boiler recently so discounted this also !
