    Boiler internal fuse keeps blowing together with the pump

    I know it's a very late response but just for the sake of any future Googlers. It turned out to be a pump. I have called in another "gas man" and he replaced the pump. This time it worked. :D

    Boiler internal fuse keeps blowing together with the pump

    I have tested at the pump terminals with the wires disconnected. Just to be clear, I actually don't get a reading when I check L and E. It just shows 1 as if I haven't touched anything with the multimeter probes.

    Boiler internal fuse keeps blowing together with the pump

    Yes, I have double checked, it's 1ohm between L and E on the pump. I get about 0.4ohm when the meter probes connected together. It looks like I don't have 3Amp fuse anywhere so will have to go and get one before I can try connecting it to the mains. By the way, thank you very much for the...

    Boiler internal fuse keeps blowing together with the pump

    Some but the plumber assured me that it's nothing to worry about and he's seen much worse. The water is not brown.

    Boiler internal fuse keeps blowing together with the pump

    I don't think it was dry, because the pressure seems to be above 1bar. I can't imagine that there would be so much dirt/debris in the water for it to have no flow. I spoke to the plumber who replaced the pumps and he is just guessing now. He's got a theory that because a non original pump...

    Boiler internal fuse keeps blowing together with the pump

    Two different makes were used (Grundfos and Bosch) and only the pump head was replaced by the plumber. Is this the one I need then? http://www.plumbclick.co.uk/circulating-pump-cp53.html For this price I am happy to give it a try.

    Boiler internal fuse keeps blowing together with the pump

    It was Grundfos initially then two Bosch and the last one is Grundfos. I am not sure the pump was blowing the fuse. What else could it be, is there a way to test it?

    Boiler internal fuse keeps blowing together with the pump

    I don't think the pump becomes hotter than the pipes beside it. Heating and hot water works ok. I didn't see what happened to the pump for the first two times (it just stopped turning and they were shortened out) but the third time I actually saw some smoke coming from the area where the wires...

    Boiler internal fuse keeps blowing together with the pump

    I unplug the pump where the wire goes into it (L, N and E). Measured the resistance, between L and E I get 1. Between L and N I get 26.

    Boiler internal fuse keeps blowing together with the pump

    Could it be a short circuit somewhere in the wires? Should I try to fit fast blow fuse instead? Is it possible that I burned three pumps by putting the time delay instead of quick blow fuse in and wouldn't the PCB itself burn before the pump? If I disconnect the pump then the boiler fires up ok...

    Boiler internal fuse keeps blowing together with the pump

    The fuse packaging does not say F5a or T3a anywhere but it says "Time Delay 1.6A". And on the fuse itself it says T1.6AL250V

    Boiler internal fuse keeps blowing together with the pump

    It's exactly like the one that was on the board and was working fine for at least 5 years (when I moved into the property). Maplin product code: GL61R. I can't link to the product directly but it's on this page: http://www.maplin.co.uk/20mm-glass-time-delay-t-fuses-452 Search for GL61R...

    Boiler internal fuse keeps blowing together with the pump

    I got Sime Friendly Format 80E boiler which keeps blowing main PCB fuses and the pump. Few weeks ago the pump gave up the ghost and it looked like a simple fix so the plumber replaced the pump. The fuse on the main PCB was also blown which I thought was the result of the pump shortening...
