A dishwasher that refuses to drain disrupts your entire kitchen routine, and the problem often appears without warning. Edmonton Repair Appliances understands how stressful this feels because standing water affects floors, cabinets, and plumbing if you ignore it. Therefore, you benefit from learning the first steps that restore normal draining. This guide explains common causes and simple fixes so you solve the issue early.
Checking the Filter and Drain Basket
Food particles collect in the filter during every wash cycle. As a result, debris slows the flow of water and eventually stops drainage completely. Firstly, remove the bottom rack and twist the filter out. You should rinse it under warm water to remove grease and sludge. Secondly, wipe the drain basket because buildup hides in corners and blocks the openings. In other words, this small task prevents repeat clogs and keeps the water moving through the system.
Meanwhile, check the sump area for seeds or softened scraps. You can also spin the spray arms and inspect the holes for trapped particles. In addition, review your manual because recommended cleaning schedules vary by model.
Checking the Drain Hose for Kinks or Blockages
The drain hose sends dirty water from the dishwasher into the plumbing system. When the hose kinks, no water passes through. Firstly, slide the appliance forward enough to see the hose. You should look for crushed sections that restrict water movement. Secondly, feel along the hose for heavy spots that indicate grease buildup. In this situation, flushing the hose clears the obstruction.
However, deeper blockages require professional help. Edmonton Repair Appliances can remove the hose safely and clean it without causing leaks. Consequently, the dishwasher drains correctly on the next cycle.
Checking the Garbage Disposal Connection
Many Edmonton kitchens connect the dishwasher drain directly to a garbage disposal. If the disposal inlet blocks, the dishwasher backs up. Firstly, disconnect power to the disposal so you can inspect the inlet safely. Secondly, remove the hose clamp and check for leftover debris. After that, run the disposal with cold water to clear the interior chamber.
On the other hand, if your disposal was recently installed, confirm the knockout plug was removed. If the plug remains, no water can enter the disposal at all.
Checking the Air Gap or High Loop
Drainage issues often come from a blocked air gap or a hose that does not follow the correct high loop shape. To clarify, both prevent dirty sink water from flowing back inside the dishwasher. You can remove the air gap cap and rinse debris out. Similarly, confirm the hose sits high under the counter rather than sagging. A low hose allows wastewater to return, which keeps water inside the tub.
Testing the Drain Pump
The drain pump pushes water out of the dishwasher. If debris blocks the impeller, the pump hums but fails to move water. Meanwhile, a silent pump may indicate an electrical issue. Because pump access requires technical skill, Edmonton Repair Appliances handles this repair when simple troubleshooting does not solve the problem.

FAQ
Why does my dishwasher keep water at the bottom

How often should I clean my dishwasher filter
Monthly cleaning works for most homes. However, daily use requires more frequent maintenance.
What if I hear a humming noise during draining
A humming pump indicates something may block the impeller. Clearing debris or calling for service solves the problem.
