What Are the Top 6 Causes of a Dishwasher Not Draining?
Across the hundreds of dishwasher drain service calls we handle in Toronto each year, six causes account for the overwhelming majority of cases. Understanding them helps you decide whether to attempt a basic fix yourself or call for professional service immediately.
- Clogged drain filter — Most modern dishwashers have a manual-clean filter at the bottom of the tub. Grease, food particles, and mineral deposits build up over time until water cannot pass. This is the single most common cause of incomplete draining.
- Blocked drain hose — The drain hose runs from the pump to the sink connection. Kinks, clogs, or improper installation height can all prevent drainage.
- Clogged garbage disposal connection — If the dishwasher drains into a garbage disposal, a full disposal or a blocked knockout plug (on new installations) will cause the dishwasher to back up.
- Missing or improper high drain loop — The drain hose must loop up to counter height before dropping to the sink connection. Without this loop, water can siphon back into the tub.
- Failed drain pump motor — When the pump motor burns out or seizes, water has no path out regardless of how clear the filter and hose are.
- Check valve failure — A stuck-open or stuck-closed check valve (flapper) at the pump outlet can either prevent drainage or allow backflow.
How Can I Fix a Dishwasher Not Draining Myself?
Clean the drain filter
Twist counterclockwise and lift out the cylindrical filter inside the tub. Rinse it under hot running water with a soft brush. Reinstall and run a Drain/Cancel cycle. This single step resolves the majority of drain issues.
Check the garbage disposal
Run the garbage disposal for 30 seconds before starting the dishwasher. If you recently installed a new disposal, check that the knockout plug has been removed from the dishwasher inlet on the disposal body.
Inspect the drain hose for kinks
Look under the sink or behind the dishwasher for sharp bends in the drain hose. A kinked hose drastically reduces flow. Straighten any kinks and verify the hose has a proper high loop.
Run a Reset or Cancel/Drain cycle
Many dishwashers can be reset by pressing the Cancel/Drain button and holding for 3 seconds. This runs a brief drain pump cycle and may clear a mid-cycle error that left water in the tub.

Warning: Never add liquid drain cleaner (Drano, etc.) to a dishwasher in an attempt to clear a blocked drain. These caustic chemicals can damage the rubber seals, plastic pump housing, and internal hoses — turning a simple drain call into a much more expensive repair. Use only dishwasher-safe descaler products.
When Do You Need a Technician for a Dishwasher Drain Problem?
Call a professional when cleaning the filter and checking the hose does not resolve the standing water. Specifically, drain pump failure, check valve replacement, and control board faults all require proper tools, testing equipment, and parts that are not practical to source and install without experience.
