Dishwasher Not Draining? Here's How to Fix It
Advice
Photo: RDNE Stock project / Pexels Finding a pool of water at the bottom of your dishwasher after a cycle is frustrating — but the fix is often simpler than you think. Work through these checks in order.
Clean the filter
Most modern dishwashers have a removable filter at the bottom. Twist it out, rinse away food debris and grease under hot water, and reinstall. A clogged filter is the number-one cause of poor draining.
Check the drain hose
A kinked or clogged drain hose stops water from leaving. Inspect the hose behind the unit for bends, and clear any blockage where it connects to the sink drain or disposal.
Clear the garbage disposal
If your dishwasher drains into a disposal, run the disposal first. A common miss: a new disposal still has the drain plug (knockout) in place, blocking the dishwasher line.
Inspect the air gap
The small cylinder on your sink is the air gap. Unscrew the cap and clear any debris — a clogged air gap backs water up into the dishwasher.
Test the drain pump
If everything above is clear, the drain pump or its motor may have failed. You may hear a humming without water movement. This is a job for a technician.
