Firstly thanks for earlier replies on the se 80 pump. this is still the same problem really, the 2amp fuse keeps blowing. I stripped the electric connection box off the top and it was wet inside (due to pressure switch leak), dried it all out but to no avail. With a good fuse in and the main power on the pump is making a buzzing sound and gets very hot, took the front off and it is free to turn. Due to my lack of electric knowledge i'm stumped. I think that maybe the poor pump has gone to a better place and needs replacing unless anyone has any other ideas. Many thanks.
