Whirlpool du920 dishwasher not draining after wash cycle

Hi

Thanks for using FixYa. Dishwasher not draining properly or not draining at all issues can arise due to different reasons. Usually, these issues are related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter.

Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn’t overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn’t working properly, the drain pump isn’t working correctly, or possibly there is a plumbing problem in your home’s drain lines.


First check whether the drain is not clogged or blocked and the line is not kinked. Check all the hoses for blockages & also clean the air gap. Has the disposer been replaced recently? If so, chances are the knockout is still in place. Simply remove the drain hose from the disposer, and knock out the plug. If the disposer has not been replaced, try removing the drain hose from the disposer and use a wet-dry vacuum (prepared for water, of course) to **** any water (and hopefully anything else) from the drain line. Then reconnect the hose, and test the unit. If you have checked the air gap and the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
