Troubleshooting
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 ExtraRinse keys for 3
seconds again, or
2) press Off, or
3) unplug the machine.
Pressing the Rotary Selector 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.
