While your washer is in standby mode, perform these key presses quickly (you should not take more than 6 seconds to complete the action)..

  • Press Heated Dry then Normal then Heated Dry then Normal.

Here are a few things you should know about the field service test on Kitchenaid KUDD03DT drawer dishwasher: 

  • The Heavy Wash/Anti-Bacterial LED will flash during the test (All other LEDs will illuminate).
  • If you open the dishwasher door during the test, the test sequence pauses. Close the door, if you want to resume it.
  • The mode is designed to perform tests on the Sensors, Memory, and Loads.
  • If an error is found, the “Cancel” LED will flash (with the fault code)- pressing any key  typically exits  the  error  display mode.

So you will basically be repeating the same 3 keys you select in the indicated sequence (there should be no more than a 1 second delay between the key presses).

It is important to note that the diagnostics cycle will only start upon closing the door.

Kitchenaid dishwasher diagnostic mode – useful tips

Various tests are run

Don’t forget that diverse tests are executed once the Kitchenaid dishwasher diagnostic mode has started.

To add, a test will either be aborted if an issue is found or an error code displayed.


Use Google to determine what the error code means

Now, if you notice an error code, you can Google for its meaning (and possible DIY fix) instead of making a service call (it could save you $$$).

Also, remember that all LEDs turn on immediately, upon the entry of the keys sequence -indeed, all segments of the display should illuminate.

Side Note: If any LED doesn’t turn on, probably there exists an open circuit (in the keypad) and you might need to replace the console assembly/keypad to fix the issue.


You can advance from interval to the next rapidly

Once the diagnostics cycle has started, you can manually advance it rapidly (to your next desired interval) by pressing the “Start/Resume” key (or “Pots & Pans” key/“Anti-Bacteria/Cookware cycle” key/ “Soak& Scrub” key in some kitchenaid dishwasher models).

Please note that the door needs to be latched after every key press to proceed to the next interval.


Wrapping it up

If you did not find the key press sequence needed to run the diagnostic mode in your specific kitchenaid dishwasher model, try to search for its tech sheet online (the procedure should be included).

One final tip: You can cancel the currently running diagnostic mode at any time, if you so wish- all you need to do is simply press the “CANCEL” button.

  1. My kdte254ewh1 will not go into diagnostic mode. I’ve tried several procedures several times cut power several times several length of time up to 1hr. Could there be a problem with control board . Lights come on when I touch them.
