✅ Cross Reference Information
WD21X20451, WD21X10532, WG03F05898
Common Symptoms
- Dishwasher does not respond to controls despite confirmed power
- Wash, drain, or dry functions do not operate in the expected sequence
- Cycle stops, fails to start, or runs out of sequence
- Intermittent operation or control-related error indications
Check Before Replacing
- Confirm the dishwasher has electrical power by checking the circuit breaker and observing whether other dishwasher controls or indicators operate.
- Perform the model’s normal power reset procedure before condemning the control board.
- Check that the door closes and latches fully, since the control board depends on the door-latch signal to permit operation.
- Inspect accessible wiring and harness connectors for loose connections, visible damage, or signs of pinching; do not disconnect or test energized wiring.
- Verify the exact dishwasher model and compare the installed board’s part number before ordering a replacement.
Pro Tip
A nonresponsive dishwasher does not by itself prove that the control board has failed; first verify power, door-latch operation, and visible harness connections.
