Dishwasher - Water in the Tub
Water settled in the bottom of the dishwasher at the end of the wash cycle is normal. This water helps to keep the pump seal lubricated. Water should not be as high as the front of the center raised island in the bottom of the tub.
If there is excessive water in the tub at the end of a cycle, you may have a draining issue. See Dishwasher Does Not Drain
