Dishwasher: Why is my dishwasher leaking?
Don't ignore a leak from your dishwasher--water can quickly damage your flooring or subflooring. If water leaks from the bottom of the door, a damaged or stuck spray arm could be causing a wave action inside the washer tub that has water sloshing over the front lip of the tub. Check the spray arms for damage and make sure they spin freely after loading the dishwasher. Other causes of leaks from around the front door include a loose or broken door hinge and a damaged door seal.
Leaks under the dishwasher can be caused by a leaking drain line, broken heating element water seal, leaking pump and motor assembly or leak in the water inlet assembly.

Replace the dishwasher heating element

You’ll also need to replace the heating element if broken element water seals allow water to leak through the bottom of the tub.

Replace the dishwasher circulation pump and motor assembly
Several situations can require the replacing the circulation pump and motor assembly in a dishwasher. If the motor on the circulation pump fails, then the dishwasher pump won't run at all. Sometimes the motor runs but doesn't generate water pressure through the spray arms, because the damaged impeller or pump housing is damaged. The pump housing and/or the seals could also deteriorate or become damaged, causing the dishwasher to leak. Problems inside the pump and motor assembly can create abnormal noises in the dishwasher. In all these situations, the pump and motor usually must be replaced.

Replace the dishwasher water inlet assembly
The water inlet assembly is an apparatus that is mounted to the side of the dishwasher tub near the water inlet valve.

If the vent or the connecting hose is clogged, then the inlet assembly will need to be repaired or replaced.
