I am working on a Maytag dishwasher M# MDB6601AWB. The dishwasher programs and fills, but when it is done filling it does nothing for about a minute then shuts off. It will fill and cancel/drain every time. I have done the field service and manual function tests. It always says “low voltage”. I checked the motor windings and capacitor, both check good. I also checked; door switch, heater, and float switch. All three check out good. I have 120v to control board, but never any voltage to motor. Replaced main control, no improvement. Replaced control console, no improvement. Any help would be greatly appreciated.
Check the voltage at the motor? Also, have you verified the polarity of your power source and ground? Many times a machine will go through manual forced tests OK but when it comes to running the actual programming sequence, that’s when weird things show up.Also the The Honeywell turbidity sensor is monitored during the wash phase. If it is faulty, it can throw the unit into a cancel /drain cycle. Measure your voltage at the power connection and run the wash motor in Diagnostic mode if it will respond. Check for any signs of voltage drop when the motor is energized. If there is no voltage at the motor during diagnostics, there’s a good chance the wiring harness is affected. There were issues with wires being cut where they cross the bottom of the door from the control.
