Thank you for your response. I believe I need to purchase a new dishwasher since this is getting too complex. I have a multimeter and there a momentary spurt of voltage when the motor tries to start. Since the motor does not run, I cannot tell any voltage drops since the voltge spurt is momentary. Since I replaced the motor and pump assembly there are no obstructions and the water fills properly. It is at the start of the wash cycle that the motor tries to start. I ran the function test that is described in the wiring schematic under the kick plate on the washer. It showed a Motor - Low current fault. I do not know how to check the low current at the motor. There are no leaks of detergent and all connections seem to be clean and tight. Thank you for your help, my wife is now making me do the dishes.

ANSWER Hello Joe. Based on the information you provided, it sounds like the PCB assembly 99002824 is bad and will need to be replaced. If the motor is new and the wires are good, you will need to replace the board in the unit. Hope this helps.
