Most Frequent Causes for Dishwasher not draining

Cause 1Drain Pump

The drain pump uses an impeller to force water through the drain hose. If the drain pump motor is not working, the dishwasher won’t drain. To determine if the drain pump is defective, check the pump motor for continuity using a multimeter. If the motor does not have continuity, or if is getting power but won’t run, replace the drain pump. Drain pumps are not repairable—if the drain pump is defective, you must replace it.

Cause 2Pump and Motor Assembly

The motor drives an impeller to force water out of the drain hose. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Cause 3Clogged or Improperly Installed Garbage Disposer

If the garbage disposer was installed recently, the drain plug may not have been removed. All garbage disposers are sold with a solid plug in the drain tube. If the dishwasher is not connected to the garbage disposer, the plug must remain in the drain tube. However, if the dishwasher is connected to the garbage disposer, the plug must be removed. If the garbage disposer wasn't replaced recently, it is possible that the disposer is clogged. Remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.

Cause 4Drain Hose

The drain hose might be clogged. To unclog the drain hose, remove the drain hose from both the dishwasher and the sink drain and clean it out. The drain hose is most commonly clogged near the garbage disposer or dishwasher drain branch tailpiece.
