Dishwasher - Detergent Stuck in Cup
To minimize the possibility of electric shock, unplug this appliance from the power supply, or disconnect power at the household circuit breaker/fuse box, before attempting any maintenance or cleaning.
If you have dishwasher detergent stuck in the soap cup after a full cycle, please check for the following conditions:
- The incoming water temperature to the dishwasher should be 120 degrees (140 degrees if your dishwasher does not have water heating capability).
- Check the spray arms for any blockage in spray holes or items that would restrict its turning.
- Verify the spray arms are turning on their own. To test:
- Mark the spray arms with a piece of tape or a rubber band or observe their position.
- 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 on some models.
- 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.
- Make sure the soap cup has opened at the end of the cycle.
- Check the sump area inside the dishwasher for any restrictions.
- Allow the dishwasher to fill and make sure it is getting a proper amount of water. The dishwasher should fill for about 90 seconds. On Permatuf® plastic tub models, the water should measure 3/8" above the island near the center of the tub. On all other models, the water should measure about 1/2" below the heating element.
- Make sure the soap cup is not blocked by anything.
