Why is Detergent Remaining in the Maytag Dishwasher Dispenser

• If the previous cycle did not complete, the detergent can become caked in the dispenser cup if it is left sitting in the dishwasher. 
• Items blocking the detergent dispenser will keep it from opening. Make sure water action can reach the dispenser. Do not load large items in front of the dispenser.
• Check that nothing blocks the upper or lower spray arm. Items in rack can block the spray arms. If the arms are blocked, the detergent door may not open fully, and may not dissolve entirely.
