Is Detergent remaining in the Dispenser?
Here are a few things to check if you notice detergent remaining in the detergent dispenser of your dishwasher at the end of the cycle. This is applicable for both powder detergent and detergent packs (pods).
Is there detergent caked in the dispenser?
Clean dispenser when caked detergent is present. Older detergent exposed to air will clump and not dissolve well, which will cause the dispenser door to stick to the detergent. Replace detergent if necessary and store the detergent in a tightly closed container in a cool dry place.

Are you using packets?
Detergent packets usually dissolve more easily, and should be placed in the dispenser the same as powdered or gel. If they are not dissolving, verify water temperature, and run the hot water in the sink closest to the dishwasher.
Is the Upper Rack in the Lowest Position?
Sometimes it is possible that the upper rack can block the detergent dispenser from opening completely when in the lowest position. Move the upper rack up to a higher position to unblock the detergent dispenser.
