Detergent Type

• Using the wrong kind of detergent can cause the soap dispenser to malfunction and can also create too many suds in the dishwasher, creating leaks and other problems with the unit. Automatic dishwasher detergent in tablet, powder or liquid form is recommended. Follow product directions for the correct amount to be used.
  
  

Stale Detergent

• Over time, powdered detergent may begin to clump or get stale. If this detergent is used in the dishwasher, it can clump and stick to the detergent cup and fail to dispense. Store detergent in a covered container, and discard unused detergent after approximately eight months. Note that liquid detergent should not get stale.
  
  

Mixing Detergent Types

• While it may seem like a good idea to mix different types of detergent to increase overall cleaning, different detergent types may clump together or form a residue, preventing the dispenser cup from releasing. For instance, mixing a chlorine-based soap with an enzyme-based soap will create a jelly-like residue that coats the inside of the detergent cup and does not release effectively. Use only one kind of detergent for each wash.
  
  

Water Temperature

• Another factor that may prevent the soap from dispensing correctly is low water temperature. Check the household hot water to verify that it reaches 120 degrees Fahrenheit or more so it can properly dissolve the detergent during the wash cycle.
  
  

Blocked Dispenser

• The soap in the dispenser will not be able to release if the cup is blocked by items in the dishwasher. Make sure the dishwasher is not overloaded, and avoid setting large items in the racks in front of the detergent cup that might keep the cup from opening as expected during the wash cycle.
