Hi all -- i just got a rebuilt 2 hp pump after the old one (1 hp) started buzzing. Seems to work OK at first but it gets very very hot after a few minutes of use. A few times it has auto shut down, and after a few minutes it would start back up.
I've checked the breakers (I changed the one inside the house to a 30, since there's 10 wire running to the outside), made sure the connections to the motor are snug (they are clips), made sure the wires are not touching, the ground wire is firmly attached, the filters and everything is clean. The plumbing is 1.5, and the pool, which includes a spill-over spa all running on the same pump, is about 22k-25K gallons (it's 16'x36'). Pump-pool distance/elevation is average. And I made sure to change the impeller to that of a 2 hp.
Could it be that I'm running too much HP power on the pool? What else could cause the pump to run hot? I just turned it on, and it ran for 30 minutes. But it was so hot as to water bubbled when I sprinkled the top of the motor case.
