how to: fix a dishwasher that won't drain

A dishwasher that doesn’t drain properly can be frustrating, but fear not – many issues are fixable with a bit of troubleshooting. Follow these steps to address and resolve a dishwasher drainage problem: 

Why Is Your Dishwasher Not Draining? 

  • Blockage: Accumulated debris or foreign objects can obstruct the drainage system. 
  • Clogged Filter: A dirty or clogged filter may impede water drainage.

 

 

Troubleshooting Steps: 

1.Inspect the Drain Hose:  Check for kinks, twists, or blockages in the dishwasher’s drain hose. Ensure it’s properly connected to the sink’s drain or garbage disposal. 

2. Clean the Filter: Locate and clean the dishwasher filter. A clogged filter can prevent proper drainage. Refer to your dishwasher’s manual for filter removal and cleaning instructions.

3. Clear the Garbage Disposal:  If your dishwasher drains into a garbage disposal, make sure it’s not clogged. Run the disposal to clear any blockages.

4. Check the Air Gap: If your dishwasher has an air gap (usually located on the sink or countertop), inspect it for debris and clean it if necessary. 

 5. Inspect the Drain Pump: Examine the dishwasher’s drain pump for any obstructions. Refer to the manual for guidance on accessing and cleaning the pump. 

6. Run a Vinegar Cycle:  Pour a cup of white vinegar into the dishwasher and run a cycle without dishes. Vinegar helps dissolve deposits that might be causing drainage issues. 

7. Consult the Manual:  Refer to your dishwasher’s manual for specific troubleshooting steps and maintenance recommendations. 

 

Tips: 

  • Regular Maintenance: Clean the dishwasher filter and inspect the drain components periodically to prevent future issues. 
  • Use Proper Detergent: Ensure you’re using dishwasher detergent suitable for your machine.
