Was the dispenser cup wet when you added detergent?
Make sure the dispenser cup is dry before adding powdered detergent. If dispenser cup is wet, the detergent can clump.
Is the cycle incomplete?
If the previous cycle did not complete, the detergent can become caked in the dispenser cup if it is left sitting in the dishwasher.
Is the detergent old?
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.
Is the water temperature too low?
For best washing and drying results, water should be 120oF (49o C) as it enters the dishwasher.
Were items blocking the dispenser that kept it from opening?
Items blocking the detergent dispenser will keep it from opening. Make sure water action can reach the dispenser.
