Common Symptoms
- Washer controls are unresponsive.
- Washer stops during a cycle.
- Washer fails to perform a controlled function such as filling, washing, draining, or spinning.
Check Before Replacing
- Verify the washer's exact model number and use the model-specific technical sheet or service information to record any displayed diagnostic code before replacing the board.
- With power disconnected, inspect the control board area and its wire connections for obvious heat damage, discoloration, or loose connectors.
- Confirm the washer has normal household power and that the symptom is not isolated to a single externally controlled component before attributing the problem to the ACU.
Pro Tip
An ACU controls several washer systems, so a no-start, fill, drain, or spin symptom alone does not prove the board has failed; document any error code and rule out the affected external component or connection first.
