Dishwasher motor not turning

Question

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.
