Dishwasher - Detergent Cup Did Not Open

There are 3 types of detergent cups that have been used on our Dishwashers, depending upon the age and model. Understanding the type of soap cup design you have will allow you to ensure the cup is not blocked or stuck closed.

Using the Detergent Cup

• Sliding Cover: Slide the cover forward into the closed position.
• Round Detergent Cover with Handle: Turn the handle on the round cover to close.
• Square Flip-Up Cover: Press down on the cover until it snaps closed.

Diagnosing a Detergent Cup That Did Not Open

If your Dishwasher is not dispensing detergent or you discover that your detergent cup did not open, there are a few things you can check.

Obstruction

• Load dishes so that they do not block the detergent cup from opening. Make sure pot handles and other tall items are not touching the detergent cup. For more information, see our Dishwasher - Loading Tips article.
• On Dishwashers with flip open detergent cups, it is normal for the cup cover to open against the upper rack. The cover opens to about a 45 degree opening. This design allows the jets at the ends of the lower spray arm to direct hot water into the detergent cup and dissolve the detergent pod, powder or liquid detergent.

Detergent

• Check to see if there is soap residue from the previous wash cycle remaining in the cup and wipe out any old detergent from the cup. For more information, see our Dishwasher - Removing Soap Residue in Detergent Cup article.
• Detergent packs (pods) or tablets are recommended and often provide improved wash performance over liquid or powder detergent. For more information, see our Dishwasher - Using the Right Detergent and Rinse Agent article.
• • If using tablets or pods, make sure they are not binding the cup cover and preventing it from opening. Make sure they are properly lined up in the opening.
  • If using powder detergent, it should be fresh and loose, not lumpy.

Timer

• The timer or control may be out of position or locked up. You can consult the appropriate article below.
