A dishwasher that will not drain is more than an inconvenience — standing water can lead to unpleasant odors and even mold growth. Fortunately, many drainage issues have straightforward causes that a professional can fix quickly.
The most common reason a dishwasher will not drain is a clogged filter or drain hose. Food particles, grease, and debris accumulate over time and block the water from exiting properly.
Top Causes of Dishwasher Drainage Problems
- Clogged filter or drain basket — most modern dishwashers have a removable filter at the bottom that needs regular cleaning
- Blocked drain hose — the hose connecting your dishwasher to the sink drain or garbage disposal can kink or clog
- Garbage disposal connection — if your dishwasher drains through a disposal, a clogged disposal will back up into the dishwasher
- Faulty drain pump — the pump that forces water out can fail mechanically or electrically
- Air gap or check valve issues — these prevent backflow and can become blocked
What You Can Try First
Check and clean the filter at the bottom of the dishwasher. Run the garbage disposal to clear any blockage. Check under the sink for kinks in the drain hose. If none of these solve it, the issue likely requires professional diagnosis.
