Whirlpool duet washer troubleshooting – How to Enter Whirlpool duet washer diagnostic mode

Putting Whirlpool duet washer into diagnostic mode is not a hard thing to do..

Simply follow these steps:

How to Enter Whirlpool duet washer diagnostic mode – Step by step for Whirlpool duet front load washer

For Whirlpool duet front load washer, you just need to poke any 3 keys three(3) times (other than the Power button) to put your washer into diagnostic mode.

For instance, you can just poke Spin, Soil, & Extra Rinse buttons in that sequence, three times in fairly quick succession.

So “Spin” will be button 1, “Soil” button 2, and “Extra Rinse” button 3- you want to poke 1-2-3 buttons once, twice, and a third time.

This puts it into diagnostic mode and error codes (if there are any) will be flashed- you want to note each code and look it up in the tech sheet for the actual meaning and suggested fixes.

Remember that getting the washer out of diagnostic mode takes three pokes to power button.


How to enter Whirlpool Duet Sport diagnostic mode

To put Whirlpool Duet Sport in diagnostic mode, you need to press any button (except pause and cancel) as below.

Please note that this procedure starts with the Service History Mode and then runs Diagnostic Test..


  • Close the door.
  • Press then hold your chosen button for 4 seconds
  • Then release the button for 4 seconds
  • Again press and hold the button for 4 seconds
  • Release the button for 4 seconds once again.
  • Now press and hold the button for 4 seconds one last time.

Once you release the button, all the console LED lights turn on for about 5 seconds- this shows you have succeeded.

If there are some error codes, all the cycle LED lights flash and the relevant Status LEDs will turn on (The failure code displays on the Estimated Time Display-if available).

Bear in mind that there could be more than one error code so press the key you have been using (remember the key) to move forward (and see which other error codes pop up).

If there aren’t further failure codes, all LED lights (on the console) turn on again for approximately 5 seconds.

Next, the machine starts the Diagnostic Test.

Note: To go out of the service mode, you press PAUSE/CANCEL (This exits the program)
