FAULT CODE DISPLAY MODE
To access fault/error codes, perform steps
1 and 2 of Activating the Service Diagnostic
Modes. Turn the cycle selector knob until the
status LED’s or display correspond as follows:

“Done” LED On, “
01
” Displayed on 7-segment
01
Sensing Soak Wash Rinse Spin Done
Press the START button to enter Fault Code
Display Mode.
1. To view last 4 fault codes:
Turn cycle selector knob clockwise to view
fault codes in the order of most recent to
oldest. (Refer to Fault/Error Code charts
on pages 6 & 7.)
NOTE: A fault/error code will be removed
from memory if it does not reoccur after
10 consecutive wash cycles.
2. To clear fault codes:
Turn cycle selector knob until the status
LED’s correspond as follows:
Sensing Soak Wash Rinse Spin Done
Press and hold
START button for
3 seconds to clear all fault codes.
Fault/Error Code Display Method
Fault/error codes are displayed by alternating
the state of the Status LED’s and display (if
display exists) in one-second intervals. All fault/
error codes have an F# and an E#. The F#
indicates “Type of Fault” and the E# indicates
“Component system where fault is located.”
*If the Sensing LED is
ON , the Fault Number
is represented; if
OFF, the Error Number is
represented (see example below). The remaining
LED’s (Wash, Rinse, Spin, and Done) represent
the fault and error code. (See Fault/Error Code
Charts on pages 6 & 7 for more information.)
NOTE: LED names will vary on selected models.
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 speci fi c troubleshooting tests.
