Dishwasher - Detergent Stuck in Cup

If you have dishwasher detergent remaining in the soap cup after the end of a wash cycle, it often means water is not being directed into the detergent cup or that the water temperature is too low. The tips provided below may enable you to resolve the concern without the need for a repair.

Diagnosing Detergent Stuck in the Soap Cup

1. Check the spray arms for any blocked spray holes.
2. Make sure the soap cup is not blocked by anything such as utensils in the silverware basket or dishware.
3. Verify that the spray arms are turning on their own. To test this, do the following:
   1. Mark the spray arms with a piece of tape or a rubber band or observe their position.
   2. Run the Dishwasher for at least 3 minutes. It is necessary to run the Dishwasher for at least three minutes because the spray arms alternate water circulation back and forth on some models.
   3. Open the Dishwasher door and observe the location of the spray arms. They should be in a different position than when the test was started.
4. Make sure the soap cup is fully opened at the end of the wash cycle.
5. Check the filter area inside the dishwasher for any restrictions.
6. The incoming water temperature should be at least 120 degrees Fahrenheit and no more than 140 degrees Fahrenheit. You can test the incoming water temperature by running hot water into a container at the sink and measuring the temperature there.
