Whirlpool Washer LdU — What It Means & How to Fix It
Also shown as dU on some models.
LdU or dU means the lid cannot unlock because the washer detects something resting on it — take the laundry basket or other objects off the lid.
What this code means
Whirlpool defines LdU as lid cannot unlock: the washer detects that objects on the lid are preventing it from unlocking. Its example is a laundry basket left on top of the washer. With the weight removed, the lock can retract.
Appears on Whirlpool top-load washers; dU is the shorter form of the same message.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Laundry basket or other object resting on the lid | Very common | Yes — no tools |
| Someone leaning on the lid as the cycle ends | Occasional | Yes — no tools |
| Lid lock stuck or failed | Occasional | No — technician job |
What you can try yourself
- Take everything off the top of the washer.
- Wait a minute for the lock to release; you should hear it click.
- Lift the lid gently — do not force it.
- If it stays locked, unplug the washer for 5 minutes, plug it back in and try again.
Seeing the symptom rather than the code? Washer door or lid trouble: checks that apply across brands.
When to call a technician
- The lid remains locked with nothing on it, even after a power reset.
- LdU shows at the end of every cycle.
- You would have to pry the lid to open it — stop and call for service.
Typical professional repair cost: No cost when weight on the lid was the cause; a lid lock replacement runs about $120–$220.
Frequently asked questions
Why won't my Whirlpool washer lid unlock?
If LdU or dU is displayed, the washer detects objects on the lid preventing it from unlocking. Remove them.
What does dU mean on a Whirlpool washer?
Lid cannot unlock — the same message as LdU.
Should I force the lid open?
