What does the Kenmore Washer error code dU mean? Causes & fixes
Quick answer: On many Kenmore top-load washers, dU usually means lid unlock failure. The washer finished or paused a step, but the lid lock system did not release the way it should.
What this code usually means
dU often points to a stuck or failed lid lock assembly, wiring trouble, or a mechanical issue preventing the latch from releasing properly.
What you may notice
- Lid stays locked unexpectedly
- Cycle ends but lid will not open right away
- Washer pauses with dU on the display
- Clicking sounds from the lid-lock area
Safety first
Turn the washer off before trying any reset steps. Do not pry or force the lid open because that can break the latch assembly.
Quick checks you can try
- Unplug the washer for several minutes and restore power.
- Make sure nothing is binding the lid or strike area.
- Check for detergent residue or debris near the latch opening.
Common causes and likely parts
- Failed lid lock assembly
- Latch mechanism stuck
- Loose or damaged wiring
- Misaligned lid strike
