How to Check the Drain Loop on a Whirlpool Dishwasher
Your dishwasher may be siphoning. Make sure to connect the drain hose to the waste tee or disposer inlet above the drain trap in the house plumbing and 20" (50.8 cm) minimum above the floor.
Make sure to use an air gap if the drain hose is connected to house plumbing lower than 20" (50.8 cm) above the subfloor or floor.
