Diagnostic Test
The diagnostic test is used to check individual washer
component function only.
To Start The Test:
•
Turn Program Knob to the start position, Spin Only.
•
Press START/PAUSE to start the cycle and save it.
•
Press CANCEL to stop the cycle and turn off LEDs.
•
Press CANCEL again to turn on the LEDs.
•
Within 5 seconds, press and hold the OPTIONS and
START/PAUSE buttons until LEDs start sequentially
chasing, then release buttons.
1. All the LEDs will sequentially light. Pressing a
button below a light cluster will light all the LEDs in
that cluster at one time to confirm functionality.
2. Turn the program knob (1) click clockwise from the
start position. The hot water solenoid will activate
and hot water should enter through the detergent
compartment.
3. Turn the program knob (2) clicks from the start
position. The bleach water solenoid will activate and
cold water should enter through the bleach
compartment.
4. Turn the program knob (3) clicks from the start
position. The bleach and the wash water solenoids
will activate and cold water should enter through the
softener compartment.
5. Turn the program knob (4) clicks from the start
position. The door lock solenoid will deactivate and
the loading door can be opened. When the door is
opened, the drum light should turn on.
6. Turn the program knob (5) clicks from the start
position. The washer will fill and tumble. Once
tumbling has started, the Boost Heater (if so
equipped) will turn on.
7. Turn the program knob (6) clicks from the start
position. The drain pump & door lock solenoid will
activate and the washer will operate in high spin.
WARNING
If power is removed during this test, the door can be
opened. To prevent injury, DO NOT put your hands
inside when the tub is rotating.
8. Turn the program knob (7) clicks from the start
position. The control will signal the last error code.

Exiting Diagnostic Mode
There are two options for exiting the Diagnostic Test
mode and returning the washer to normal operation:
a) Unplug the power cord, wait 5-8 seconds, then
reconnect the power cord OR
b) Turn the program knob clockwise 2 or 3 clicks after
the start position. Press OPTIONS and START/
PAUSE buttons together for a few seconds until wash
cycle LEDs appear.
If a situation arises where you cannot exit the Diagnostic
mode as described above, and the bank of 5 LED's on
the right end remain ON regardless of Program Knob
position, a combination of pushed buttons may have
caused the control to enter a special factory test mode.
If this occurs, disconnect power to reset the control to
return washer to normal operation.
Drum Light Circuit Testing
To test the drum light circuit, remove the top of washer
to gain access to terminals of the stepdown transformer.
With the washer door open, measure the voltage drop
between the input terminals of the transformer.
If the meter reads zero, remove the door switch and
check it with an Ohm meter. If the contacts are open
with the plunger out, replace the door switch. If the
contacts are closed, replace the control board.
If the meter reads line to neutral voltage, measure the
voltage drop between the two output terminals. If the
meter read zero the transformer is defective. If the
meter reads 12 volts, the light is defective.
NOTE
Since it is recommended that the loading door be left
open when the washer not in use, the electronic
control board limits the amount of time the drum light
is on. With the loading door open, the electronic
control board allows power to the light for a maximum
of (3) minutes.
If the drum light remains on for more than (3) minutes
with the loading door opened, replace the electronic con-
trol board. If the drum light remains on with the loading
door closed, replace the light switch.
