DO NOT REMOVE OR DESTROY
ACTIVATING THE SERVICE DIAGNOSTIC
TEST MODES
1.
Be sure the washer is in standby mode (plugged in with all
indicators off, or all indicators lit but not flashing).
NOTE:
There are 5 failure modes that can cause the washer
to go out of service, indicated by all of the LEDs lit, but not
flashing. When this occurs, the washer cannot be started until
the condition that caused the failure is corrected and the fault
code is cleared. Use the following steps to enter into Fault Code
Display Mode, view the fault code, and clear logged fault codes.
2.
Perform the following sequence of movement using the cycle
selector knob.
NOTE: AFTER RESET
,
sequence “a” through “e” must be
completed within
6 seconds
, stopping just briefly between each
click (resulting in the following sequence: Left - Right - Right -
Left - Right, as indicated below).
RESET
- Place cycle selector knob pointer at 12 o’clock
position and wait 3–4 seconds before proceeding.
a. Rotate cycle selector knob
counterclockwise
one click.
b. Rotate cycle selector knob
clockwise
one click.
c. Rotate cycle selector knob
clockwise
one click.
d. Rotate cycle selector knob
counterclockwise
one click.
e. Rotate cycle selector knob
clockwise
one click.
Successful activation of Diagnostic Test Modes will be
indicated by all status LEDs (except for Lid Locked)
flashing ON and OFF in half-second intervals.
NOTE:
LED names may vary between makes and models.
Legend: = ON
= OFF
Figure 2 - Status LEDs flashing ON and OFF
If the status LEDs do not display as described above, the
sequence may not have been completed within 6 seconds.
Repeat step 2 to ensure this was not the cause. If still
unsuccessful, see Unsuccessful Entry, page 3.

DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Has a fuse blown or circuit breaker tripped? Was a regular
fuse used? A time-delay fuse is required.
Are both hot and cold water faucets open and water supply
hoses unobstructed?
All tests/checks should be made with a VOM (volt-ohm-
milliammeter) or DVM (digital-voltmeter) having a sensitivity
of 20,000
Ω
per volt DC or greater.
Resistance checks must be made with washer unplugged
or power disconnected.
IMPORTANT:
Avoid using large diameter probes when
checking harness connectors as the probes may damage
the connectors upon insertion.
Check all harnesses and connections before replacing
components. Look for connectors not fully seated, broken
or loose wires and terminals, or wires not pressed into
connectors far enough to engage metal barbs.
A potential cause of a control not functioning is corrosion
or contamination on connections. Use an ohmmeter to check
for continuity across suspected connections.
DIAGNOSTIC LED – MAIN CONTROL
A troubleshooting tool has been implemented onto the main
control board—a diagnostic LED.
LED ON
– The Control is detecting correct incoming line voltage
and the processor is functioning.
LED OFF
– Control malfunction. Perform TEST #1: Main Control,
page 12, to verify main control functionality.
SERVICE DIAGNOSTIC TEST MODES
These tests allow factory or service personnel to test and verify
all inputs to the main control board. You may want to do a quick
and overall checkup of the washer with these tests before going
to specific troubleshooting tests.
