If you have a crack in your basket you may have a clogged impeller. With the power off reach back into the pump through the pump pot with a long screwdriver and feel around. If it feels spongey it there you have a clog. Take the serew driver an use an oceleting motion in a counter clockwise direction this should loosen the clog then reach in with a long set of thin pliers and pull the clog out. This should fix your problem and once water is flowing your pump should quiet down.

I have a Hayward Super Pool pump for my inground pool. Was running the pump, heard a noise, by the time I got over to the pump to check it it shut off. It has been off for over 2 hours. It is not hot....


Get another brand. Hayward is junk. I had the same exact thing happen. Of course warranty is only one year. I paid out of pocket to replace the motor. Guess what happened 2 years later?

Pump runs for about 3min and shuts off


It sounds like it is overheating. There is a thermal switch that shuts the motor off if it gets too hot. This may be because the motor is pulling too many amps due to a bad winding or the bearings are starting to seize. The best solution is to replace the motor.

Pump runs for about 3min and shuts off/


That's the motors internal thermal switch doing its job. For some reason your motor is running hot. With the breaker off, remove the end cap on the back of the motor and use a 9/16 open ended wrench to see if the motor shaft turns freely. If it doesn't there may be some debris jammed at the impeller, or the bearings may be failing.
If the shaft moves freely the problem is probably internal to the motor. Usually a bad winding, Northstar pump motors average about 4-5 years, so if it is older than that or getting close the best bet is replacement.

Northstar 1.5 hp pump motor is always hot and shuts off for ten minutes aned comes back on. The voltage and amperage is good. What's the problem


It has an internal thermal overload protection device that is turning it off. Once it cools enough it will automatically turn back on as long as whatever switch or timer you have controlling the pump is in the on position. If you are certain it is not due to a voltage or load condition then it would seem the only other problem is mechanical.

In any case try a local electric motor repair shop.
