Pool Pump overheating

Postby tlarson95 » Mon 24 May, 2010 13:23

We just opened our pool this weekend and our pump (Hayward 1.5HP) is running very hot to the touch. If we shut it off and try to turn it back on, it blows our circuit breaker. If we let it cool down and start it up again, it starts, but very rough. It hesitates a bit and then starts up. But then within an hour it is hot again. It doesn't shut off on its own but I'm afraid to keep it running for long periods when it is that hot to the touch. Even when it cools down overnight, when we start it it hesitates for a bit and then finally starts. Anyone have any idea what could be wrong or what we should do? I have no idea how to even take it apart or what to do.

Pool Pump overheating

Sounds like a bearing is starting to fail. This will make the motor hard to start and will create extra load on the motor causing it to overheat. How old is the motor/pump? Is it making any unusual noises?

Bearings are replaceable albeit difficult to do but you can usually find a motor shop to do if for you. Also, you could either replace the motor or use this as a opportunity to get a more efficient pump.
