glow worm ultimate fuse F2

[redrocky]

Fuse F2 has blown on my boiler.
I replaced the fuse. As soon as power is put on to the boiler (without switching on controller for hot water or heating) the fuse blows.
Is it the PCB ?

Any help please.

probably the pump is knackered

 

[redrocky]

could it be the pump ? The fuse blows as soon as I power up the boiler, without the programmer calling for the boiler to fire ?

 

[mickyg]

just unplug everything from the pcb and plug em back in one by one until it goes pop


ps i hold no liability for result of advice given (ie electrocutions )

very often a dead pump blows the boards even if there is no demand.

try disconnecting hte pump ELECTRIC OFF OF COURSE and turn the boiler on



If it still blows call in a professional to have a butchers
