Home > Dishwasher Repair > Dishwasher Not Draining

You open the dishwasher after a cycle and there is a pool of dirty water in the bottom. Before you panic: a dishwasher that will not drain is the most common dishwasher fault of all, and the cause is a blockage somewhere along a short path — filter, sump, hose, air gap, disposal — more often than a failed pump.

The Most Common Causes

Safe Checks You Can Do Yourself

When It Is Time to Call a Technician

If the filter and air gap are clean and water still stands after a drain cycle, the pump or its power needs testing. We also check the check valve — a machine that drains and then refills with dirty water has a different fault than one that never drains.

Frequently Asked Questions

Is a little water in the bottom normal?

A small amount in the sump below the filter is normal and keeps seals wet. Water covering the base of the tub is not — that is a drain fault.

Why did my dishwasher stop draining after a new disposal was installed?

The disposal's dishwasher inlet ships with a solid plug that must be knocked out during installation. If it was missed, the dishwasher has nowhere to drain. It is a five-minute fix once identified.

Can a blocked dishwasher drain flood my kitchen?

It can overflow on the next cycle and leak past the door seal. Bail the water out, avoid running it, and get the drain path cleared.

Do you give the price before starting the repair?

Always. The technician first diagnoses the problem, then gives you one flat quote. We only start the repair after you approve the price, and the quote does not change at the end.
