Hi,

I went to put my heating on last night only to find the boiler was unresponsive and no lights on the control panel were showing.

Looking to the fused spur, the light was still on so that fuse was fine.

I opened it up to check the internal 2a fuse ( not one directly on board)

Anyway it was blown. And so the next day I got replacements and tried it again. It blew straight away on trying to switch it on.

I unplugged the pump on the board so it had no power and it allowed the boiler to start up. When I plugged it back in again it started for a bit then blew another fuse.

From this I can only think that it is the pump causing the problem.

The boiler is 1year 4 months old and is a sabre 29he.

It has a grundfos ups 50 pump.

Can anyone give me any pointers? Much appreciated!

Pumps should be run now and again through the summer to stop them sticking.

If you protect any electrics, you can remove the big screw in the center and free the pump with a small screwdriver.

There's a slot on the end of the shaft.

Thanks scruff!

Oh we have been running it now and then so it's not been idle. I'll try turning it just now anyway...

It was on in the morning from 6 to 8... I was off all day and in the house with no heating on, The mrs was on her way home from work so I thought I'll out the heating on for he as she's always cold and that's when I noticed

Can you connect the pump to a fly lead and run it without the boiler on for say 30 mins.

Hi scruff not sure how best to do that? Do you mean disconnect pump from board and the live neutral and earth connections on the side of the actual pump and make my own lead up?

Yes, if you keep blowing the fuse you'll risk damaging something expensive.

Agile will be on later and may have a few ideas.

Okie I will give that a shot after work tomorrow... Will this help determine if it's buggered? If it blows A plug fuse then it's no good?

Oh and I checked inside of pump by turning with small screwdriver and it turns fine...

I've just connected the pump up to a plug and have it running, what does this mean? It appears to be running ok....

The cable supplying the pump might be duff?

The pump might not be causing fuse to blow so it is something else?

Or.....

Hmmm help! :)

It is most unlikely to be the cable so only as a last resort should you bother with that. In any case you could reconnect it to the PCB after insulating the pump end with tape.

Pumps often take an overcurrent and this is sometimes very intermittent. Quite often this is just a high start up current surge but in other cases it just suddenly takes a higher current. This is not necessarily enough to blow a mains 3A fuse.

Ideally run it for a day or two with a 3A mains fuse in the plug. If you can measure the current taken then even better.

Almost certainly the pump is going to have to be changed unless you want to run it on a mains lead for ever.
