KitchenAid Dishwasher Diagnostic Mode

Modern dishwashers, like those from KitchenAid, are equipped with advanced features and technology to ensure efficient and effective cleaning of your dishes. One useful feature is the diagnostic mode, which allows you to troubleshoot and identify issues with your dishwasher. In this guide, we will explore how to access and use the diagnostic mode on a KitchenAid dishwasher.

Accessing Diagnostic Mode


Step 1: Start with an Empty Dishwasher Before attempting to enter the diagnostic mode, ensure that the dishwasher is empty and that there are no dishes or utensils inside.

Step 2: Turn off the Dishwasher Make sure the dishwasher is turned off. If it’s running, wait for the current cycle to complete, or press the “Cancel” button to stop it.

Step 3: Access the Control Panel Locate the control panel on your dishwasher. This is typically on the top of the door or along the side, depending on the model. You’ll find a series of buttons and a display screen.

Step 4: Enter Diagnostic Mode The exact button combination to enter diagnostic mode can vary. However, it often involves pressing a specific sequence of buttons. Refer to your dishwasher’s user manual or follow these general steps:

  • Press and hold the “Heated Dry” button for about 5 seconds.
  • Release the “Heated Dry” button and then press it again.
  • Repeat the above step three more times, so you press the “Heated Dry” button five times in total.
  • After the fifth press, the dishwasher should enter diagnostic mode. You’ll see all the lights on the control panel illuminate.

Using Diagnostic Mode

Once you’ve successfully entered diagnostic mode, you can use it to identify problems and gather information about your dishwasher’s performance. Here are some common functions available in diagnostic mode:

1. Cycle Testing You can initiate a diagnostic cycle test, which runs the dishwasher through a series of tests to check various components, such as the heating element, water inlet valve, and spray arms. Follow the on-screen instructions to start the test.

2. Error Code Display If there’s a problem with your dishwasher, it may display an error code during the diagnostic test. Refer to your dishwasher’s manual or look up the specific error code to identify the issue.

3. Sensor Testing You can test various sensors, like the turbidity sensor or the water temperature sensor, to ensure they are functioning correctly.

4. Clearing Error Codes After identifying and fixing an issue, you can use the diagnostic mode to clear error codes and reset the dishwasher’s control board.

Additional Tips and Considerations

  1. Interpreting Error Codes: When using the diagnostic mode, pay close attention to any error codes that may appear on the display. These codes are your dishwasher’s way of communicating what’s wrong. Refer to your dishwasher’s manual or KitchenAid’s official website for a comprehensive list of error codes and their meanings. Understanding these codes can save you time and money on repairs.
  2. Taking Notes: Keep a notebook or your smartphone handy to jot down any error codes or unusual behavior you observe during the diagnostic cycle. This information can be invaluable when you consult with a technician or search for solutions online.
  3. Safety First: While accessing the diagnostic mode is relatively straightforward, always prioritize safety. Ensure that the dishwasher is disconnected from the power source before attempting any troubleshooting or repairs. Avoid contact with electrical components and hot water during the diagnostic cycle.
  4. Consulting the Manual: Your dishwasher’s user manual is a valuable resource. It provides detailed instructions on how to use the diagnostic mode for your specific model. It’s a good practice to keep the manual in an easily accessible location for quick reference.
  5. DIY Repairs: Some minor issues that you discover in diagnostic mode may be fixable without the need for a technician. For instance, you might find a clogged spray arm or a loose connection. However, for more complex issues or if you’re unsure about making repairs, it’s best to seek professional assistance to avoid damaging your dishwasher further.
  6. Regular Maintenance: Use the diagnostic mode as part of your regular maintenance routine to catch problems early and ensure your dishwasher continues to work efficiently. Cleaning filters, inspecting spray arms, and checking for loose or damaged components can help prevent major breakdowns.
  7. Customer Support: If you’re unable to resolve an issue using the diagnostic mode or if the problem persists, don’t hesitate to contact KitchenAid’s customer support or schedule a service call with an authorized technician. They have the expertise and tools to diagnose and fix more complex problems.
  8. Warranty Considerations: If your dishwasher is still under warranty, be cautious about performing extensive DIY repairs, as this could void the warranty. Check the warranty terms and consider reaching out to KitchenAid’s customer support for guidance on covered repairs.
