Right I have just upgraded my pump and bout a 1/2 hp pump and sand filter. Got it all wired up and was working fine however I woke up the following morning and the pump wasnt working. After taking the cover off the pump the capacitor has blown a hole in the side of it. I have sourced a replacement cap but my question is could how I wired it up have caused this or does the fact that it was working for a few hours mean its wired up ok?
