A dishwasher that won't drain is usually due to a clogged filter, a kinked or blocked drain hose, or a stuck air gap. Food debris and grease buildup are the most common culprits. This guide will help you clear the blockage and get your dishwasher draining properly again.

See what's happening and how to try the first recovery step.

Check the Drain Hose for KinksPull the dishwasher out slightly and inspect the corrugated drain hose underneath. Straighten any sharp bends or kinks that could block water flow.

Inspect the Air Gap (if you have one)Open the small cap on the countertop near the sink (the air gap). Remove the plastic cover inside and clean out any debris with a toothpick or small brush.

Disconnect and Flush the Drain HoseDisconnect the drain hose from the garbage disposal or sink drain. Place the end in a bucket and run a rinse cycle. Water should flow freely. Use a plumber's snake if it's clogged.

Clear the Garbage Disposal Knockout PlugIf the hose connects to the disposal, check that the knockout plug (a small plastic disc) was removed when the disposal was installed. Use a hammer and screwdriver to break it out if present.
