Reconditioned pcb, now what!

[Neil Carroll]

I've just bought a reconditioned pcb for my ferroli 901, I've had one in the past from the same company no problems, when I plugged this one in the leds just come on very faintly and go off, the clock works and the pump runs but nothing else, is this likely to be a faulty board, all wires look fine and they are definitely in the correct place, the fan isn't running so I'm assuming that's why everything else hasn't kicked it, the fan ran fine before the pcb change, does the dull led give any clues, I'm assuming it's a lack of power to the board somewhere

Thanks in advance.

Why did you replace the pcb? Are you going to be able to check for safety afterwards?

Is this in relation to this problem?

Possible external expansion tank error

I've just fitted an external expansion vessel to my ferroli as the internal one was passing a lot of water, it's created another problem, it all went well, fitted to return pipe ( i double checked) joint eventually stopped leaking but then.... When I fire up the boiler in burns for about...

I wouldn't advise that swapping bits out is the answer, especially PCB's. Do you have the kit and experience and are able to check and test the PCB and it's outputs etc and then all the other components that may be at fault, that would have been the first place to start.

Also, as suggested, if you don't have the kit nor experience then you won't be able to ensure that the boiler is running safely once it is running, it may make more sense having a GSR engineer in to take a look.
