A detergent door may be blocked by a pan or rack, stuck by damp detergent, or fail because the cycle never reached the release stage. Check what was in front of the dispenser and reload with it clear. With the machine off, clean the cup and the latch area with a damp cloth as the manual allows.

Isolate the failing boundary
ReversibleRun empty with a clean dry cup and verify the selected cycle advances beyond prewash.
Apply the narrow correction
ReversibleCorrect loading and clean residue using the approved method; do not oil the dispenser.
Verify the result and stop at the boundary

Exact questions
Common questions
Why is detergent left in the cup after the cycle?+
Most often the door was blocked, the lid was damp or the cycle stopped before the release stage. Fix loading and dryness first.
Why does the detergent door not open?+
A blocked door, wet detergent or a stuck release mechanism can prevent it from opening.
Can the water be too cold?+
Yes. Cold water can leave detergent undissolved. Run hot water at the sink first.
What if the latch is broken?+
Replacing the dispenser assembly may be needed.
