The diagnostic mode works by running a series of tests on the different parts of the washer to ensure they are working optimally. It views logged washer errors, performs an automatic diagnostic cycle, and checks different components to scrutinize their working conditions.

Specifically, the diagnostic mode checks different parts, including the water valve, drain pump, motor sensor, and heater, to test if they have any problems. When you run the diagnostic mode, it can fix minor anomalies and return different error codes to indicate a major problem.

The error codes will point the users to the source of the problem. Some models of the Whirlpool washer have a digital screen to display the error code, while some will use the status lights on the console to beep a sequence which will then be interpreted into a code.

Whirlpool Washer Diagnostic Mode: How To Activate

The diagnostic mode enables you to test or inspect all inputs to your washing machine’s main control board. If you want to activate this mode, there are several methods you can go about it. The methods are the same across various models of Whirlpool washers, with only minor variation in some cases.

You can enter the diagnostic mode by combining different keys/buttons on the control panel. Before you start, you should ensure you put your machine in standby mode. The standby mode means your washer will be plugged-in, but all the indicators will be off.

  • Ensure your washer is in a standby-mode
  • Note any three different buttons/keys from the control panel

  • This process must be completed within 8 seconds. (Press the three keys of three different types within 8 seconds)
  • The process will put the machine into self-test diagnostic mode successfully. To confirm the process, all the indicators on the machine console will light up for five seconds with a tone sound.

If the test detects a significant problem, it will return an error code to notify you of the problem. You must familiarize yourself with the interpretation of each error code to be able to tackle the situation accordingly.
