Maytag Washer - dU Error Code

The washer cannot unlock the door or lid.

Meaning

The washer cannot unlock the door or lid.

The Maytag dU error code indicates that the washer attempted to unlock the door or lid but did not detect the unlocked position. This code appears across multiple Maytag platforms, including front-load MAH models, top-load Bravos/Bravos XL/Centennial/VMW models, and Neptune TL washers. While the hardware differs: front-load models use a door lock assembly with a wax motor or solenoid, and top-load models use a lid lock solenoid or magnetic sensor the meaning is the same; the control cannot confirm that the lock disengaged. When this occurs, the washer may trap clothing inside, stop mid-cycle, or refuse to restart.

Model-Specific Notes

Front-load models commonly experience dU due to wax motor or solenoid failures that prevent the lock from releasing. Bravos, Centennial, and VMW top-load models typically trigger dU due to failed lid lock solenoids or stuck latches. Neptune TL models use a magnetic lid lock that may fail due to sensor or harness issues.
