Turn off the power and remove the end cap at the center back end of the motor. The end of the motor shaft is then exposed and you can use a 9/16" open end wrench to verify that the motor shaft is turning freely.
If it offers resistance the pump needs to be opened and checked to find out why. If it does move freely, take it to a pool store or motor shop to test it. Rarely, a motor gets out of the factory DOA.

    I took the motor back and he tested it and it was good. I don't understand the old pump was running bad so I took it off and it was going to cost more to fix it so i just got a new motor but it is a one speed not a two speed would that make a differents. It's a 2 hp not a 11/2 but he said it would work. What do you think?

    The 2 HP will work fine, it will just cost a little more to run.

SOURCE: Hayward Self-Priming Pump with AO Smith 1 HP 56J

the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck

SOURCE: The pump only hums when plugged in. Any suggestions?

It sounds like the impellor is locked. Take this part off and then see if the pump is turning but before you do, some of them have a big screw driver slot in the shaft. If it does, turn it to see if you can free the impellor. I have done this many times and they will continue to work for years after. They just get stuck from rust, etc. and also being frozen a little. Hope this helps.

If AO Smith 1.5 HP pool pump mootor is turning the wrong direction could that be the reason for not priming. If so how do you change the direction of spin?


these motor have been known to do this, you could have the capacitor checked or replaced, it might be a bad motor.. i would look to see that the shaft seal is good (new) and no suction leaks and that the pump has been primed.. if not its time 4 a new shaft seal.. it only takes a short time to burn up the shaft seal

Remove the back of the motor ... you will find there are flats on the shaft. Put your 7/16 or 1/2 open end wrench there and with your other hand, spin off the broken impeller.

The motor may have blown the start capacitor. It is the black cylinder about 1-1/2" dia x 2-1/2" long. Look at the end with the wires for a small hole. Is it blackened or have a hole blown thru? If so replace it. Otherwise have a local electric motor repair shop look at it for possible repair or replacement.
