Dishwasher Not Draining? Causes and Fast Repair

Standing water in the bottom of your dishwasher after a cycle means it is not draining, and while it looks alarming, the cause is usually straightforward. Platinum Appliance Repair diagnoses and repairs dishwasher draining problems same-day across Northern Virginia.

Why Your Dishwasher Won’t Drain

The most frequent causes are a clogged filter at the bottom of the tub packed with food debris, a blocked or kinked drain hose, a failed drain pump, or a clogged garbage disposal or air gap where the dishwasher connects to your sink plumbing. A very common overlooked cause is a new garbage disposal whose drain plug was never knocked out during installation, which blocks the dishwasher from draining entirely. Failed check valves and control-board faults account for most of the rest.

What You Can Check First

Run your garbage disposal, since a backed-up disposal often prevents the dishwasher from draining, and check that the drain hose is not kinked. If you can access and clean the filter at the bottom of the tub, that resolves a fair number of cases. If water remains after those checks, the drain pump or a plumbing connection likely needs professional attention.
