Customer Questions and Answers for Service Machine Control by Ge

4.89 (64)
By: Ge
Part Number: OEM21647328
Manufacturer Part Number: WD21X24901C

The Service Machine Control is an OEM component specifically designed for GE dishwashers. As the main control board, it regulates all wash cycles including temperature, filtration, spray arm rotation, drying functions and end of cycle signals.

Causes of a faulty service machine control include normal wear and tear over time. Electronic failures or water exposure from plumbing issues can also trigger malfunctions.

Symptoms of a failing control board are:

  • Inability to progress through cycles fully
  • Flashing error codes during washes
  • Inconsistent wash and rinse performance
  • Component damage from power overload issues

Replacing it with this genuine GE OEM part restores optimal cycle handling. Proper controls are essential for sanitizing every wash. The part is also compatible with Hotpoint, RCA and some Kenmore models.

Zandk for Model Number GDT695SSJ2SS

For the past several months it would randomly beep throughout the day but would always finish a cycle once started. About two weeks it went completely dead. Before checking the machine board, I ordered a new one, WD21X24901C. That did not fix the problem. Both the new machine board and old one show a green LED. I checked the J722 connector on the new machine board from pin 2 to pin 5 and see 13.5 volts. Is there anything else I can check? Not sure how to proceed next. Thanks.

Answer

Hello ZandK, thank you for contacting Appliance Parts Pros. This style was known to have an issue with the wiring harness WD21X21664/[OEM24136862] that runs between the user interface and the main control board, it is recommended to replace that harness.
