A problem with the above boiler, when you ask for HW or CH the boiler starts and stops and starts and stops few times and works for some times and starts the same thing again and again, I can hear the relays clicking on the RH PCB, what could it be

yes very common new rh pcb make sure you match up the board part number written on the small black transformer as there are two both will fit an appear to work but one of them won't actually light the burner if in wrong boiler. The parts centre people tend to be unaware of this even if you give them a gc number for the boiler they will get you the wrong version.

Or you could get cet to recondition your board all it needs is acouple of relays. Catch it now before they catch fire and take out the tracks on the pcb.

Otherwise a much hated yet reliable boiler. usual diaphragm issues but no real design faults. just cheap and tatty but fundctional.

Well worth a rh pcb.
