Dead Boiler


Postby bcam » Wed May 09, 2007 11:36 am

Hi all, just new to the forum so hello, the problem i have is , my boiler ( not sure what model ) has decided to stop working so i have no heating or hot water, the pilot light is still lit but when i try to turn it on there is nothing!! previously when i turned on the power there would be a click and the burner would kick on but there is absolutely nothing now!
Does this sound familiar to anyone?
Any advice is more than welcome.
Cheers.

I have read in this Forum, that the pump can be a mite reluctant to move if left unused for a while, but might respond to setting it to max speed (my Grundfos has 3 speeds). Elsewhere in this forum I read about a bleed-point at the pump where a screw-driver might be inserted to persuade a stuck impeller to move. Pumps can get so crudded that even tho' they may sound and feel healthy, they produce practically no flow.
My pump costs only £71 inc VAT. and can be replaced without any draining, as there is an isolating valve fitted onto each end.

dont bother. if the pump was faulty the boiler would fire for a short while then overheat. its more likely to be programmer or motorised valve

The boiler is a Baxi wm 381 RS, i found the plug fuse had blown so i tried a higher rated fuse , it also blew, i traced the wiring and found no shorting but when i tried the higher fuse the pump tried to move for a nano second then the fuse blew, do you recon its the pump and it may be a case of changing it and everything will be hunky dory??
I couldnt find a PCB anywhere on the boiler amd had it practically stripped.

Quick update, can now get the boiler to fire but stops after around 20-30 secs, i can only assume from an earlier answer that the pump is indee knackered and needs replacing.
