Safety First: Work on the dispenser with power off if removing any screws.

Verify fill: Ensure the rinse aid reservoir is actually full and the cap is properly seated.
Clean outlet: Wipe around the dispenser outlet inside the door to remove any film or buildup.
Adjust setting: Increase the rinse aid dosage setting to ensure adequate dispensing.
When to call for service: If the level never drops and spotting persists, the dispenser assembly or control output may need replacement.

Rinse aid is not dispensing; dishes spot and the rinse aid level never seems to drop.
