I have a Suprima 50 and 3 years ago I replaced the pcb with part no 5111603. Last night I noticed that the system pump was running however the programmed time was off. I checked the boiler and found a constant red light. According to the info that came with the replacement pcb this is a "system wiring fault" the cause of which is "either pump live is not wired directly from the boiler to the pump" or, "live and neutral are reversed"
As the pump is running and no work has been done to intefere with any of the wiring does this mean that this "updated" pcb is faulty as well !!!!!!!!!!!!!
Can anyone help please
