What the washer is detecting
At the end of a cycle the control retracts the lock bolt. If it cannot confirm the unlocked position, dU flashes and the lid stays locked.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented Pressure on the lid preventing the bolt from retracting.
- Documented Detergent or lint buildup blocking the bolt.
- Documented The control unable to read the lock state.
Safe checks you can make
- Make sure nothing is resting on the lid, then unplug the washer for one minute and plug it back in.
- Do not pry the lid open.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Runs the lid lock test.
- Checks the lock mechanism and wiring.

Repair or replace?
A fault code alone rarely justifies replacing a washer. Most dU repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 10–13-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
