ACTIVATING THE SERVICE
DIAGNOSTIC TEST MODES
1.
Be sure the washer is in standby mode
(plugged in with all indicators off).
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
.
RESET
- Rotate cycle selector knob
counterclockwise
one or more clicks
to clear sequence.
a. Rotate cycle selector knob
clockwise
one click and wait ½ second.
b. Rotate cycle selector knob
clockwise
one click and wait ½ second.
c. Rotate cycle selector knob
clockwise
one click and wait ½ second.
d. Rotate cycle selector knob
counterclockwise
one click and
wait ½ second.
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,

DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Has a household fuse blown or circuit breaker
tripped? Was a regular fuse used? Inform
customer that 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, on page 12, to verify main control
functionality.
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.
