How Do You Troubleshoot Standing Water at the Bottom of a KitchenAid Dishwasher?

When water remains standing in the bottom of the dishwasher, KitchenAid recommends troubleshooting by checking to see if the door is unlatched or open. If it accidentally opens or didn't completely close, the interruption in the cycle leaves water standing in the machine.

Once most KitchenAid dishwashers finish their cycles, a clean light indicates the cycle is complete. When this light is on, pressing the cancel/drain button starts the pump to remove any remaining water. If operating this cycle doesn't clear the standing water, the issue is likely with a plugged drain.

With newly installed dishwashers that drain through a garbage disposal, the installer sometimes forgets to remove the knockout plug from the inlet. If the machine was working well earlier, but stops draining suddenly, the problem might be food left in the disposal unit or a clogged sink drain.

Foreign material sometimes blocks the air gap. Most of these units have a lift off chrome cover over a plastic cap that unscrews. After removing the cap, the owner should check for soil build-up and clean as necessary.

The dishwasher's drain hose is a source of potential problems. Kinks prevent the pump from moving the water to the drain. If a replacement drain hose is longer than 12 feet, it is too long to allow the machine to work correctly.
