Water drains out of your dishwasher, so there is usually some water at the bottom. Check the drain hose for leaks, if there is a blockage or kink in the drain hose and if there is any water in the bottom of the dishwasher. A dishwasher's drain hose connects to a sink drain or garbage disposal during a wash cycle. Having a kinked or clogged water hose may cause standing water in the dishwasher after the cycle is complete.
