Diagnostic Guide
Before servicing, check the following:
n
Make sure there is power at the wall outlet.
n
Has a household fuse blown or circuit breaker tripped?
Was a regular fuse used? Inform customer that a time-
delay fuse is required.
n
Are both hot and cold water faucets open and water
supply hoses unobstructed?
n
Make sure drain hose is not sealed into drain pipe, and
that there is an air gap for ventilation. Ensure drain
height is between 39” (991 mm) and 8’ (2.4 m) above
the floor.
n
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.
n
Resistance checks must be made with washer
unplugged or power disconnected.
n
IMPORTANT: Avoid using large diameter probes when
checking harness connectors as the probes may
damage the connectors upon insertion.
n
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.
n
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 (see Figure 1).
LED Flashing
–
The Control is detecting correct incoming line voltage and the
processor is functioning.
LED OFF or ON
– Control malfunction.
Perform TEST #1: Main Control, page 6-5, to verify main
control functionality.
Self Diagnostic Mode
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.

LOCATION
ACTIVATING SERVICE DIAGNOSTIC
MODE
1. Be sure the washer is in standby mode (plugged in with all
indicators off).
2. Select any three (3) buttons (except POWER) and follow
the steps below, using the same buttons (remember the
buttons and the order that the buttons were pressed):
Within 8 seconds,
• Press and Release the
1st
selected button,
• Press and Release the
2nd
selected button,
• Press and Release the
3rd
selected button;
• Repeat this 3 button sequence 2 more times.
3. If this test mode has been entered successfully, all
indicators on the console will be illuminated for 5 seconds
with “888” showing in the three-digit display and a tone
will sound. If there are no saved fault codes, all indicators
on the console will momentarily turn off, and then only
the seven segment display will come back on and display
“888”. Upon entry to Service Diagnostic mode, all cycles
and options reset to factory default.
NOTE:
The Service Diagnostic mode will time out after
5–10 minutes of user inactivity, or shut down if AC power
is removed from the washer.
Unsuccessful Activation
If entry into diagnostic mode is unsuccessful, refer to the
following indication and action:
Indication:
None of the indicators or display turn on.
Action:
Select any cycle.
¾
If indicators come on, try to change the function for
the three buttons used to activate the diagnostic test
mode. If any button is unable to change the function,
something is faulty with the button, and it will not
be possible to enter the diagnostic mode using that
button. Replace the user interface.
¾
If no indicators come on after selecting the cycle, go to
TEST #1: Main Control, page 6-5.
Activation with Saved Fault Codes
If there is a saved fault code, it will be flashing in the display.
Review the Fault/Error Codes table on pages 5-9 to 5-11 for
the recommended procedure. If there is no saved fault code,
“888” will be displayed.
