My dishwasher makes a loud noise when operating at times. Could this be the motor? How do you take the door off this model and where is the motor located?
Answer Hello Don,
There is most likely debris in the area of the pump where the chopper blade is located. The pump will have to be disassembled to see if this is the case or not. This is the only thing that can cause the issue unless the outlet W10296525 has separated. The door will not have to be removed and the motor is under the pump assembly.
After my dishwasher fills, the unit stops and does nothing else. No motor sound, no spinning of spray arms, nothing until I hit cancel. Then it drains. Serial #13034334AV. Its a Maytag Quiet Series 100.
Answer Hello Will,
This sounds like you either have a bad winding in the motor or a bad control. Disconnect the unit from the power supply for the first tests you need to make. This is fairly easy to pin down. Remove the kick panel and unplug the motor. Using your test meter set to resistance, test from the terminal the green wire connected to to the other three terminals. None of these should read open or zero. There should be a resistance reading there, but through 45 minutes of researching I could not locate the exact resistance of the motor windings. If any of the readings are zero or open, the motor is bad. If you get a resistance reading on all three, you need to go to the next test.
The next test is for voltage. First, remember to reestablish thew power supply. Fill the unit with water so if it were working properly the motor would start. Now with your test meter set to ac voltage, test from ground to the blue wire. This is the power supply from the control board. If there is voltage there, the start capacitor or the wiring harness have an issue. If there is no voltage from ground to the blue wire, the control board has failed.
