Do you have an on/off switch that operates your pump? Also, what type of plug / recepticale do you have -- mine's a very large 4-bladed one.
I don't but wonder if there should be one. I wanted to bump my filter this morning. The timer (in the basement) on the pump had already turned it on. So I unplugged my pump and there was a spark. The breaker in the basement also tripped.
My neighbor, the electrician, is out-of-town of course. Can't raise my brother on the phone either thanks to the holiday. I went to HD and picked up a new plug (my current one had brown around one of the blades before -- now that blade has black around it). The guy suggested that I replace the recepticale also as he thought that it was most likely to have caused the problem, which makes sense. So I bought both and will replace them when it gets a little cooler tonight or tomorrow morning. But before I do, I wondered if I should change the type.
