Question about Dishwashers
I have a Maytag dishwasher with motor S62NXJKR-7560. The motor just hums and does not turn. I have already replaced the motor, the motor start relay and the sequencer. I am at a loss. Do you have any information that might help. Of particular use would be the specifications of each of the four leads to the motor, their use and applicable required voltages.
Check your start/run capacitor. It will be usually a silver oval shaped metal can or a black square plastic block usually mounted on the side or close to the motor.Usually it will be a 10 MFD cap.Unless you have a cap tester your best bet is to take it off and take it to a motor repair/rewind shop for testing.They are not expensive and if you continue to try to run the motor you WILL slowly burn it out.This cap in notorious for getting weak because this cap works full time.But before you go through all that make sure that you can turn the motor first by hand or finger.If all else fails then the windings in the motor have been damaged.Then you will have to get the motor rewound or bye a new one.Rewound is cheaper though.

I do not know this model washer, but i can tell you the motor leads are all powered by 120 VAC. there are4 because one wire is common (wired to) the other 3. each opposite end of the other 3, when powered by 120, turn the motor at different speeds because each of these 3 windings has a different number of coil turns. you can dry test the motor by first determining the common wire, then apply 120 to this wire and then, one at a time, to each of the other wires. do this test using a proven circuit-breaker-ed outlet to reduce risk.
