In this article, we will explore common reasons why a Whirlpool dishwasher may not be draining and provide troubleshooting tips and solutions to help you resolve the problem.

Common Causes of Whirlpool Dishwasher Not Draining

There are several potential reasons why your Whirlpool dishwasher may not be draining properly. Understanding these causes can help you diagnose and fix the issue effectively. Here are some comon culprits:

  • Clogged Drain Hose: A clogged or kinked drain hose can prevent water from flowing out of the dishwasher. Check the drain hose for any obstructions or bends that may be impeding the drainage.
  • Blocked Air Gap: The air gap is a small device located on the countertop or sink that prevents wastewater from flowing back into the dishwasher. If it becomes clogged with debris, it can hinder proper drainage.
  • Faulty Drain Pump: The drain pump is responsible for removing water from the dishwasher. If it malfunctions or gets clogged, it can prevent the dishwasher from draining. Inspect the drain pump for any blockages or signs of damage.
  • Clogged Filter: The dishwasher’s filter traps food particles and debris to prevent them from clogging the drain. If the filter becomes clogged, it can impede drainage. Clean the filter regularly to ensure proper water flow.
  • Garbage Disposal Connection: If your dishwasher is connected to a garbage dispsal, a clog or blockage in the disposal can affect drainage. Check the disposal for any obstructions and clear them if necessary.
