How to Troubleshoot a KitchenAid Dishwasher That Will Not Drain Out Water

KitchenAid began in 1919 with just one product--the stand mixer that it would build its company on. In 1946, KitchenAid introduced the first residential dishwasher to wash dishes with pressurized water. Since then, KitchenAid has continued to expand its line of home appliances, and its dishwashers have continued to be on the cutting edge. KitchenAid dishwashers feature a special filtration system to catch excess food since the dishwasher does not require you to prerinse your dishes. If your KitchenAid dishwasher is not draining correctly, try troubleshooting the issue yourself before spending money on an expensive repair appointment.

You can troubleshoot a dishwasher that won't drain.

Step 1

Check that the door on your KitchenAid dishwasher is securely closed and that there are no utensils or dishes blocking the door from latching completely. The dishwasher will not drain unless the door is latched.

Step 2

Run your garbage disposal system to clear any blockage that could be stopping your KitchenAid dishwasher from draining.

Step 3

Take the metal cap off your sink air gap (if you have one) and unscrew the plastic cover. Clean any debris out of the air gap and screw the plastic cover back on and replace the metal cap.

Step 4

Remove the knockout plug from your garbage disposal if your drain hose drains into the garbage disposal. Disconnect the drain hose from the garbage disposal and use needle nose pliers to pull the knockout plug out of your garbage disposal inlet. Reconnect the drain hose.

Step 5

Check your dishwasher drain hose to make sure that it is the one that was supplied with your KitchenAid dishwasher. Your dishwasher drain hose should be shorter than 12 feet long and free of kinks. Replace the drain hose if it is kinked or too long.
