Service Mode

 

 

Service Mode enables service personnel to verify the operation of the washing machine and diagnose problems. Service Mode can be entered in the middle

of any wash cycle without interrupting the cycle. While in Service Mode, the technician can cancel the current cycle, set a continuous running mode, start a variety of special service tests and view diagnostic displays.

Enter / Exit Service Mode

To enter Service Mode press the Chime and Extra Rinse keys for three seconds or until the control beeps.

NOTE: The washer must be on before Service Mode can be entered.

The motor speed will be displayed when started (motor not running display will be 0). The present state of the machine will not be changed (i.e., the current cycle in progress will not be interrupted and only the display will change). All LED’s will be turned off except the “Door Lock” LED. It will continue to display the condition of the door lock.

To exit:

1)Press Chime and Extra Rinse keys for 3 seconds again, or

2)Press Off, or

3)Unplug the machine. Pressing the Rotary Selector knob while running a test will pause the individual test, while remaining in Service Mode.

The following table summarizes special tests and features available in Service Mode, along with methods of activation and cancellation.
