Direct answer
A complete failure should be separated into power or eligibility, the external path, and the component itself before any reset. For dishwasher detergent dispenser, first run empty with a clean dry cup and confirm the cycle advances beyond prewash.
What this covers
- dishwasher detergent dispenser with this exact failure state
- Diagnosis across loading obstruction/wet cup versus latch, cycle progress and spray
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleRecord whether the feature is absent, disabled, powered but unresponsive, or showing a message. Expected behavior: release dry automatic detergent at the programmed wash stage.
Isolate the component boundary
ReversibleRun empty with a clean dry cup and confirm the cycle advances beyond prewash. Test the simplest supported configuration with unrelated accessories and optional services removed. Boundary to separate: loading obstruction/wet cup versus latch, cycle progress and spray.
Correct only the proven cause
ReversibleCorrect loading and residue; service a clean unblocked latch that never opens. Restore only the failed prerequisite or path; do not change working layers.
Verify and stop safely
ReversibleRepeat from a cold start and complete one normal use. Never add hand dish soap or lubricate the dispenser.

Common follow-ups
What should I check first when dishwasher detergent dispenser has this problem?+
Run empty with a clean dry cup and confirm the cycle advances beyond prewash.
Why not factory-reset immediately?+
The useful boundary is loading obstruction/wet cup versus latch, cycle progress and spray. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
never add hand dish soap or lubricate the dispenser.
