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.
