KitchenAid Dishwasher Troubleshooting Not Cleaning

A KitchenAid dishwasher is known for its efficiency and reliability in cleaning dishes. However, if you find that your KitchenAid dishwasher is not cleaning your dishes properly, it can be frustrating. In this guide, we will explore common reasons why your KitchenAid dishwasher might not be cleaning effectively and provide troubleshooting steps to help you resolve the issue.

1. Check Dish Loading



  • Ensure that dishes are not overcrowded, allowing water and detergent to reach all surfaces.
  • Load dishes according to the manufacturer’s guidelines to avoid blocking spray arms and nozzles.

2. Inspect Spray Arms

Issue: Clogged or damaged spray arms can lead to uneven water distribution and poor cleaning performance.


  • Remove the lower and upper spray arms and clean them thoroughly.
  • Check for any cracks or damage; if damaged, replace the spray arms.

3. Verify Water Temperature

Issue: Low water temperature can result in ineffective cleaning, as the detergent may not activate properly.


  • Run hot water in your kitchen sink before starting the dishwasher to ensure the inlet water is hot.
  • Check the dishwasher’s settings to ensure it’s set to a high-temperature wash cycle.

4. Examine Detergent Usage

Issue: Incorrect detergent or insufficient detergent can lead to poor cleaning results.


  • Use a high-quality dishwasher detergent recommended by KitchenAid.
  • Check that you are using the right amount of detergent according to the dishwasher’s user manual.

5. Clean Filters and Drain

Issue: Dirty filters or a clogged drain can hinder water circulation and drainage, affecting cleaning performance.


  • Remove and clean the dishwasher’s filters and mesh screens.
  • Check for any debris in the drain and remove it.

6. Inspect the Door Seal

Issue: A damaged or worn-out door seal can cause water leaks, reducing cleaning efficiency.


  • Carefully examine the door seal for any visible cracks or damage.
  • If necessary, replace the door seal to ensure a proper seal during the wash cycle.

7. Run a Vinegar Rinse

Issue: Mineral buildup can accumulate in the dishwasher’s spray arms and nozzles, impacting water flow.


  • Place a cup of white vinegar on the top rack of the dishwasher.
  • Run a hot water cycle with no dishes to clean and remove mineral deposits.

8. Check for Mechanical Issues

Issue: Mechanical problems such as a malfunctioning pump or motor can cause cleaning problems.


  • If none of the above steps resolve the issue, consult the dishwasher’s user manual for troubleshooting guidance.
  • If the problem persists, contact KitchenAid’s customer support or a qualified technician for further assistance.

9. Check Water Pressure

Issue: Low water pressure can impede the dishwasher’s ability to spray water effectively.


  • Ensure that the water inlet valve supplying water to the dishwasher is fully open.
  • Verify that there are no kinks or obstructions in the water supply line.

10. Scrutinize Wash Cycle Selection

Issue: Selecting the wrong wash cycle for the load can result in inadequate cleaning.


  • Review the dishwasher’s user manual to understand the various wash cycles available.
  • Choose the appropriate cycle based on the type and level of soiling on your dishes.

11. Inspect the Detergent Dispenser

Issue: A malfunctioning detergent dispenser may not release detergent at the right time during the wash cycle.


  • Examine the detergent dispenser for any blockages or damage.
  • If it’s not working correctly, it may need to be replaced.

12. Monitor Water Softener Levels

Issue: If your area has hard water, mineral buildup can affect cleaning performance.


  • Ensure that the water softener is properly filled with salt according to the manufacturer’s instructions.
  • Use a dishwasher cleaner to remove mineral deposits if they’ve already accumulated.

13. Run a Dishwasher Cleaner

Issue: Over time, residue and grease can accumulate inside the dishwasher, leading to poor cleaning.


  • Regularly use a dishwasher cleaner recommended by KitchenAid to remove buildup.
  • Follow the manufacturer’s instructions on how to use the cleaner effectively.

14. Examine the Water Filtration System

Issue: A malfunctioning water filtration system can result in dirty water recirculating during the wash cycle.


  • If your dishwasher has a filtration system, inspect it for clogs or damage.
  • Clean or replace the filter as needed to ensure clean water circulation.

15. Time Your Detergent Release

Issue: Adding detergent too early in the wash cycle can reduce its effectiveness.


  • Some KitchenAid dishwashers have a detergent dispenser that releases detergent at the right time. Ensure it’s working correctly.
  • If not, consider adding detergent just before starting the dishwasher for optimal results.

16. Test with Different Detergent Brands

Issue: In some cases, changing to a different detergent brand may improve cleaning performance.


  • Experiment with different dishwasher detergents to find one that works best for your water conditions and dishwasher model.

17. Regular Maintenance

Issue: Neglecting regular maintenance can lead to performance issues over time.


  • Follow the manufacturer’s recommended maintenance schedule, including cleaning filters and inspecting key components.
  • Ensure that all moving parts, such as racks and spray arms, are functioning properly.

18. Professional Help

Issue: If all else fails, and your KitchenAid dishwasher still isn’t cleaning properly, it may be time to seek professional assistance.


  • Contact KitchenAid’s customer support or a certified technician to diagnose and repair any underlying issues.

By systematically addressing these troubleshooting steps, you can significantly improve the cleaning performance of your KitchenAid dishwasher. Remember that regular maintenance and proper usage are key to ensuring your dishwasher continues to function at its best and keeps your dishes sparkling clean.
