Kitchenaid dishwasher wont drain - KitchenAid KAWS850LE Top Load Washer

First chec to see if your filter is plugged, inside the dishwasher. if you have really hard water it can plug them up solid, if the filter looks good, then it could be somthing stuck in the drain pump. we had a small sliver from a borken glass we dont ever remember breaking, and it was inside the pump bloking the impeller. first, locate the pump for the drain it will be rather small with hoses connected. get some 3/4" hose clamps cause you will need to cut the factory installed clamps. once you have the pump out, you need to figure out how it comes apart (either screws around the volute(case), or the volute twists off like its screwed together) once apart you should see if anything is stuck. reassemble in reverse order. if not time to call a professional. good luck

Remove the knockout plug in the disposer outlet of the garbage disposal if the dishwasher drains into the disposal. Turn off the water supply and remove the drain hose from the disposal.

Issues With the Drain Hose
8
Check to see if there is a loop in the drain hose. The loop cannot be more than 20 inches above the floor. Disconnect the hose and loop it just above the floor. Reconnect the drain hose.
9
Remove kinks in the drain hose. Always use the new drain hose included with the dishwasher. Do not reuse old hoses.
10
Check the length of the drain hose. The hose should be less than 12 feet long. Replace with a shorter hose, if needed.

If the drain is connected to the garbage disposal was the knock out plug removed from disposal.
