Dishwasher Won't Drain
Common causes, what you can check yourself, and when to call a professional — a practical guide for New York homeowners and property managers.
Most likely causes
When we get service calls in Brooklyn and Manhattan for this issue, one of these is almost always the culprit:
- Clogged filter at the base of the tub
- Blocked drain hose or air gap
- Failed drain pump
- Garbage disposal knockout plug still in place (new-install issue)
- Kinked drain hose behind the cabinet
What to check before calling a professional
Work through these in order. If none resolves the problem, it's time to schedule service.
- Remove and rinse the cylindrical filter
- Check the air gap on the countertop for debris
- Verify the disposal has been run recently — dishwashers share that drain line
- Bail standing water out before restarting

Frequently Asked Questions
Why is there standing water in my dishwasher?+
Small amount (under a cup) is normal — it keeps the pump seal wet. More than that means a clogged filter or blocked drain path.
