Hi
Worcester 28i RSF
Can anybody help. No hot water or C/Heating. Red light on front panel,fan runs,pump not running and no power from pcb to pump. Is this a PCB at fault.

check the over heat

PCB faults are rarer than a lot of people think... eliminate everything else first!

Can you hear the boiler trying to light? Any burners lit?

Have you got the Manufacturer's Instructions, and have you tried to follow the fault finding charts in them? This might narrow things down considerably.


P.S. Just seen ADLP's post... bet he's right

and the internal fuse

Thanks for the quick reply, it's not trying to spark and the 2amp fuse is ok. Followed the the fault chart. When checking the reset button with a meter should i get a beep across the terminals.

have you checked the over heat stat
other than that it could be the pcb if you have no power eaving the boiler
oh and what the pressure at

Checked overheat stat and the pressure is at 1.5bar.
