If you’re a Toronto homeowner dealing with a KitchenAid dishwasher not draining, you’re not alone. At Express Repair, we’ve helped countless customers solve this exact problem efficiently and affordably. In this guide, we’ll explain common causes, troubleshooting tips, and when it’s time to call in the pros.
There are several reasons your KitchenAid dishwasher might stop draining properly. Understanding the root cause can help you decide whether a DIY fix is possible or if professional help is needed.
1. Clogged Filter or Drain Basket
Food particles, grease, and debris often clog the dishwasher filter or drain basket. Over time, this buildup can prevent water from draining effectively.
Tip: Remove the bottom rack, locate the filter, and clean it with warm, soapy water. Be sure to check the drain basket for any visible blockages.
2. Blocked or Kinked Drain Hose
The drain hose connects the dishwasher to your kitchen sink or garbage disposal. If it’s bent, kinked, or clogged, water won’t drain properly.
Tip: Inspect the hose for damage or blockages. A gentle flush with water or a flexible cleaning brush can often resolve minor clogs.
3. Garbage Disposal Plug Not Removed
If you recently installed a new garbage disposal, the plug where the dishwasher drain hose connects may still be intact.
Tip: Make sure the knockout plug inside the garbage disposal inlet has been removed. If not, water won’t be able to pass through.
4. Faulty Drain Pump
The drain pump pushes the water out of the dishwasher. If it’s malfunctioning or blocked, the water won’t go anywhere.
Tip: Listen for strange noises during the drain cycle. If the pump is silent or unusually loud, it may need repair or replacement.
5. Clogged Air Gap (If Installed)
Some dishwashers use an air gap installed at the sink to prevent backflow. If the air gap is clogged, it can block the drainage process.
Tip: Remove the air gap cap and clean any buildup inside.
While some drainage issues can be resolved with basic troubleshooting, others require expert attention. Here are signs it’s time to call Express Appliance Repair.
