My Whirlpool Quiet Partner II will not drain at the end of the final cycle.

Hi
Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.
