DIAGNOSTIC GUIDE

Before servicing, check the following:
M ake sure there is power at the wall outlet.

H as a fuse blown or circuit breaker tripped? Was a regular

fuse used? A time-delay fuse is required.
A re both hot and cold water faucets open and water supply

hoses unobstructed?
A ll 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.
R esistance checks must be made with washer unplugged

or power disconnected.
I MPORTANT: Avoid using large diameter probes when

checking harness connectors as the probes may damage
the connectors upon insertion.
C heck 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 – No power to control or control malfunction. Perform
TEST #1: Main Control, page 12, to verify main control functionality.

FAILURE MODE
If the incoming water supply is restricted or off, the cycle will
end and the following 3 LEDs will be lit. Opening and closing the
lid will reset the control to the beginning of a new cycle. Money
from the cancelled cycle will be lost. The incoming water supply
needs to be corrected prior to starting the next cycle or the risk
of another cancelled cycle is high.
 "In Use, Rinse, & Done" LEDs On
In Soak/
Use Wash
All 5 LEDS lit and not flashing indicates that the washer is out
of service. Enter the Service Diagnostic Test Modes and then
enter Fault Code Display Mode to determine the mode of failure
and to reset the control.

SERVICE DIAGNOSTIC TEST MODES

These tests allow factory or service personnel to test and verify all
inputs to the main control board. Utilize these performance tests
before continuing to specific component troubleshooting tests.

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.
