Finding standing water at the bottom of your dishwasher can be frustrating. If your dishwasher isn’t draining properly, the good news is that many drainage problems are caused by simple issues you can check in just a few minutes.
Before scheduling a repair, try these quick troubleshooting steps that often solve the problem.
1. Check and clean the dishwasher filter
A clogged filter is one of the most common reasons a dishwasher won’t drain. Food particles, grease, and soap residue can block water from flowing out.
Quick fix:
- Turn off the dishwasher.
- Remove the bottom rack.
- Locate the filter at the bottom of the tub.
- Twist and remove the filter.
- Rinse it under warm water and remove any debris.
- Reinstall the filter and run a short cycle.
Cleaning the filter regularly helps your dishwasher drain properly and improves cleaning performance.
2. Run the garbage disposal
Many dishwashers drain through the garbage disposal. Water may remain in the dishwasher if the disposal becomes clogged.
Try this:
- Turn on the garbage disposal and run it for about 30 seconds.
- This clears debris that could be blocking the dishwasher drain line.
If you recently installed a new garbage disposal, verify that the knockout plug inside the dishwasher drain connection was removed. If it wasn’t removed, the dishwasher couldn’t drain.
3. Check for a kinked or blocked drain hose
A bent or clogged drain hose can stop water from leaving the dishwasher.
What to check:
- Look under the sink for the dishwasher drain hose.
- Make sure the hose is not kinked or pinched.
- Ensure the hose connection to the sink or disposal is clear.
When Your Dishwasher Still Won’t Drain
If these quick fixes don’t solve the problem, the issue may involve:
- A faulty drain pump
- A clogged air gap
- A damaged drain hose
- An electrical or control problem
These issues usually require professional appliance repair.

Dishwasher Not Draining? - FAQs
This usually happens when the filter is clogged, the drain hose is blocked, or the garbage disposal connection is restricted.
It’s best not to. Standing water can cause odors and may indicate a drainage issue that needs attention.
Cleaning the filter once a month helps prevent clogs and keeps your dishwasher running efficiently.
If cleaning the filter and checking the disposal doesn’t resolve the issue, a professional technician should inspect the drain pump or hose.
