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.

Frequently asked questions

Why is there water in my dishwasher after the cycle?

A small amount is normal, but standing water usually means a clogged filter, hose, or air gap.

Can I run my dishwasher with water at the bottom?

Avoid it — a blocked drain can overflow or strain the pump. Clear the clog first.

Do you repair all dishwasher brands?

Yes — Bosch, Samsung, LG, Whirlpool, KitchenAid, GE, Maytag, Frigidaire and more.
