Pool pump motor problem

My pool pump motor is running very very slowly and getting hot.

the motor turns freely by hand so I assume something has blown on the electric motor (AO smith ).

Anybody care to suggest what the problem might be.

Thanks in advance

Can't see it from here but if it has a start capasitor clamped on the side it sounds like a bad start capsitor. You being in England it may be a horse of a different color with higher voltages and still single phase service.

Sounds like the problem I had, only I got a lot of noise also. Estimate to rebuild a 2 speed 1.5 HP Jacuzzi was $263 US. A new AO Smith ran me $287.

Did it

Does the motor have starting coils that are controlled by a centrifugal switch? If so, you may find that wiping the contacts of the centrifugal switch by sliding fine emory cloth between them will cure your problem.

Suggest he check the switch to make sure its not stuck in the open position too while he's at it.

Sometimes a little dab of white grease on the joints where the weights attach will help.

It does have start capacitor, it turns over but does not spin up.

Like others have said. Sounds like a Electric Start Cluching problem. Inside the back end of the motor is a cluching system that when the motor starts. the speed of the motor get to a certain speed and it will disenguage the start winding and just have the run winding to run the motor. if this clutch does not let the start winding drop out. it will drag the motor down, slow it down, and get hot. You can buy a new clutch for most any of these motors.

Now i still can't see it from here because there is a Tanker Ship od oil crossing in the way between the U.S. and the U.K. .

You MIGHT have grass or other junk clogging up the impellor - pull the pump apart and clear it.

Has happened to me a couple of times where grass has made it past the strainer baskets - slows the filtration system down considerably.

My problem turned out to be pea sized gravel/debris cracked the impeller. I had to replace it and after that it worked just fine. Open the face of your pump and inspect the impeller, it comes out very easily with just a rubber ring gasket holding it in place. If the impeller is cracked or has chips in the outer rim, it will cause the problem you describe and a host of others.

If you replace the impeller and that does not help, then it may be time to rebuild the pump, or replace it. I recently bought a Hayward 2.5 horse for

350.00 on the internet, shipping was free.
