A dishwasher was finishing its cycle with an inch of standing water still pooled at the bottom.

Appliance

Fix Time

Same-visit

Diagnostic Roadmap

1

Drain Hose

Checked, no issue

Clear, no kinks, proper high-loop installed

2

Air Gap

Checked, no issue

Unobstructed, draining freely

3

Drain Pump

Found it

Impeller partially clogged with a food debris clump, reducing pump output

Resolution

Removed and cleared the drain pump impeller, ran two full cycles empty to confirm complete drainage, then a normal load to verify under real conditions.

Standing water almost always means something is restricting the drain path, not a dead pump. Worth a look inside before replacing the part.
