The KitchenAid dishwasher diagnostic mode is one of the advanced features that will perform various tests on your dishwasher and show an error code on the screen.

Entering a service diagnostic mode requires pressing a sequence of buttons. Many people do not know the procedure to enter the diagnostic mode. If you are one of them, you have landed in the right place.

Steps to Activate Diagnostic mode in KitchenAid Dishwasher.

Here are the simple steps that you will require to Activate diagnostic mode:

Step 1: Ensure your Dishwasher is on Standby.

To activate the Diagnostic mode, the Dishwasher should be in Standby mode. That means it should have power but not be started (No cycle should be running). 

Step 2: Press the required Buttons.

Every dishwasher has a set of buttons on its control panel. You have to the press any 3 buttons in a 1-2-3 sequence to enter diagnostic mode.

So, press the “Heat Dry,” “High-Temperature Wash,” and “Semi Rinse” buttons one after another three times. Remember, the interval between clicking these buttons should not exceed 1 second. 

This action will illuminate all the button LEDs of the dishwasher, indicating you have successfully entered diagnostic/test mode.

Step 3: Check the door latch

The unlatched doors of your dishwasher can hamper the testing process of your dishwasher. Do check and close the dishwasher doors appropriately in order to avoid such issues.

You can use the ‘Start’ and ‘Resume’ buttons to begin, pause or skip the testing. 

Step 4: Read the Error code

After performing all the tests, the dishwasher will flash the Clean LED or a small White LED a specific number of times to indicate the issue. You will have to pay attention to these LEDs.

For example, If the LED flashes eight times and then four times, it indicates an 8-4 or F8 E4 code. This code means that your dishwasher’s Float switch is stuck.

If you want to know the meaning and recommended solution of more Error codes, scroll down to the table where I have explained all the Error codes in detail.
