Well

New Fan installed and boiler fires up fine. Brilliant.

Only prob now is that when I connect the pump to the PCB the Consumer
unit trips still !

Could the fan becoming stiff (in the first instance a couple of days
ago) and so not working have somehow put load on the pump or PCB as it
was struggling to rotate.

I will test Pump tomorrow with a flex to socket on the ring!!

Fan is excellent Geoff thanks, but stay by the phone.
