What to do now
Remove objects from the lid area and give the washer time to complete the unlock action.
The lid cannot unlock because something may be preventing lid movement. Remove objects from the lid area and give the washer time to complete the unlock action. Do not keep running the appliance if the code returns or a safety sign appears.
Region: United States. This page does not generalize the code to every Whirlpool washer.
The washer is not confirming that the lid can unlock. The cited Whirlpool row points first to objects on the lid, not to an automatic lock replacement.
Confirmed: Whirlpool documents LdU for top-load HE washers as the lid not unlocking because objects on the lid may prevent unlocking.
Remove objects from the lid area and give the washer time to complete the unlock action.
Only after safe supply checks and only if the code clears.
Stop if the lid remains locked with water inside, if there is any electrical smell, or if the lid mechanism sounds abnormal.
Contact service if the lid area is clear but LdU returns or the lid remains locked after the washer has had time to unlock.
No reset procedure is published here because the current source does not document one for this scope.
Do not pry the lid or repeatedly interrupt power if the washer remains locked.
Record the model label, whether objects were on the lid, cycle state, water level, and whether LdU returned after clearing the lid area.
