I noticed on Thursday night when I unplugged the pump that it was very hot. We have a grounded electrical outlet dedicated for the pool. This is our second season using it and never a problem before. The electrician couldn't come out until today because of the holiday weekend. When I told him I run it four hours a day, he said I was running it too much. It has been tripping the breaker in the house occasionally the last couple of weeks. Anyway, I'm not comfortable with anything he's coming up with. I'll take the pump to the pool store if I have to but they are horrible to work with. I'd appreciate any thoughts here! Thank you.
