Dishwasher Soap 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 lower spray arm for any blockage in spray holes or items that would restrict its turning.
  • 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.
