Quick answer
Whirlpool top load washer dU means objects on the lid keep it from unlocking. Remove them, such as a laundry basket.
Model note: Whirlpool reuses codes across series and model years, so dU may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
dU means the lid cannot unlock because objects are on the washer lid.
Is something sitting on your Whirlpool top load washer? dU means the lid cannot unlock because the washer senses objects on it.
Take whatever is on top away, a basket of laundry for example, and the lid is free to unlock.
Other lid codes
See dLO when the lid will not lock, and E4 for a lid opened during a spin on a stacked laundry center.
