This feature holds true for all tests with exception of the
serial communication test. The serial communication test
can be run only once due to the limited time required to
run the test. Once the serial communication test has
been run, the operator must exit and reenter the mode to
repeat the test.

The Field Service Mode can be entered manually or by
inserting a special Service Mode card (available to commer-
cial laundry owners) into the SmartCard reader.
Manual entry into the Field Service mode requires the Model
Selector harness WD21X10026, to be installed into the L3D
control. This is the Service Selector harness. To install the
Service Selector harness, disconnect power to the machine
and remove the currently installed Model Selector harness.
Save the removed Model Selector harness for reinstallation
after service. Install the Service Selector harness into the
control board and reconnect power to the machine. Note:
When the service operation is completed, remove the
Service Selector harness and reinstall the previous Model
Selector harness.
After reconnecting power, the L3D control test cycle is
entered by pressing and holding the White Cotton and the
Start button simultaneously for 3 seconds. As soon as the
test cycle is entered, the control will power the Dual Seven
Segment Display (DSSD) to output the letters Fd (Field
Service Diagnostics).
Manual entrance into Field Service mode will be restricted to
the time period of 15 seconds after Power-On-Reset of the
L3D electronic control. Following this time, the key sequence
method of entry into the service mode will be disabled.
The service mode may also be entered by receiving the
appropriate command via the serial communication port
using the Service Mode Card. Entry into the Field service
mode will be allowed at any time the machine is powered
and in the idle state.
When any of the above buttons are pressed or when the
pressure switch is pushed or contacted, the control will beep
for 0.5 seconds.
The initial step after entering service mode for the L3D
electronic control will be defined as Step 0. This will
signal the DSSD to output Fd and the control will light all
LEDs. The following table gives required functions for
subsequent steps. To proceed to the next step, press the
Color Cottons pushbutton. To return to the previous position,
press the White Cottons.
