■
Check all connections before replacing
components. Look for broken or loose wires, failed
terminals, or wires not pressed into connectors far
enough.
■
A potential cause of a control not functioning is
corrosion or contamination on connections.
Observe connections and check for continuity with
an ohmmeter.
■
Connectors: Look at top of connector. Check for
broken or loose wires. Check for wires not pressed
into connector far enough to engage metal barbs.
■
Resistance checks must be made with washer
unplugged or power disconnected.
DIAGNOSTIC TESTS
There are three diagnostic test modes available:
Automatic, Manual and Console. These tests allow the
factory or service personnel to test and verify all
inputs to the machine/motor control. You may want to
allow the automatic test cycle to complete prior to
going into specific troubleshooting tests, to verify all
washer’s subsystems functionality.
ACTIVATION OF AUTOMATIC
DIAGNOSTIC TEST MODE
1.
Be sure the washer is in standby mode (plugged in
with all indicators off; or with only the Clean
indicator on).
2.
Select any one button (except POWER, START and
PAUSE/CANCEL) and follow the steps below, using
the same button:
a.
Press/hold 3 seconds.
b.
Release for 3 seconds.
c.
Press/hold 3 seconds.
d.
Release for 3 seconds.
e.
Press/hold 3 seconds.
➔
If this test mode has been entered successfully,
all indicators on the console are illuminated for
5 seconds with
88
showing in the Estimated
Time Remaining two-digit display.
➔
If indicators do not display as described above,
the press/hold/release procedure above may not
have been performed within the time frame
necessary for successful entry. Repeat step 2 to
ensure this was not the cause. If still
unsuccessful, see Diagnostic: Unsuccessful
Entry, at right.
3.
The program then checks for saved fault codes:
➔
If there are saved fault codes, see Diagnostic:
Saved Fault Codes, page 2.
➔
If there are no saved fault codes, all indicators
on the console will momentarily turn off, then
turn back on with
88
displayed. After
5 seconds, the Automatic test, below, begins.
DIAGNOSTIC: Automatic
Performs a five-minute automatic test with water
functions to check major washer functions (lid can be
open). Press the same button used in step 2 above to
advance through automatic test steps.
NOTE:
Basket must be floating in order to agitate.
Step C1 must be allowed to complete before
advancing to step C5.

* Step will occur but no water will be dispensed in
models that do not have a fabric softener cup and/or
detergent cup.
DIAGNOSTIC: Unsuccessful Entry
If entry into diagnostic mode is unsuccessful (see steps
1 and 2 of Activation of Automatic Diagnostic Test Mode,
at left), refer to the following indications and actions:
Indication 1: None of the indicators or display
turns on.
Action:
Press POWER button to enter setting mode.
➔
If indicators come on, try to change the function
for the button used to activate the diagnostic test
mode. If that button fails to change the function,
something is faulty with the button, and it is not
possible to enter the diagnostic mode.
IMPORTANT
Electrostatic Discharge (ESD) Sensitive
Electronics
ESD problems are present everywhere. ESD may
damage or weaken the electronic control assembly.
The new control assembly may appear to work well
after repair is finished, but failure may occur at a later
date due to ESD stress.
■
Use an anti-static wrist strap. Connect wrist strap
to green ground connection point or unpainted
metal in the appliance -OR- Touch your finger
repeatedly to a green ground connection point or
unpainted metal in the appliance.
■
Before removing the par t from its package, touch
the anti-static bag to a green ground connection
point or unpainted metal in the appliance.
■
Avoid touching electronic parts or terminal
contacts; handle electronic control assembly by
edges only.
■
When repackaging failed electronic control
assembly in anti-static bag, observe above
instructions.
WARNING
Electrical Shock Hazard
Disconnect power before
servicing.
Replace all parts and
panels before operating.
Failure to do so can result
in death or electrical shock.

THE FOLLOWING U.S. PATENTS:
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? Use a time-delay fuse.
■
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.
NOTE:
Avoid using large diameter probes when
checking harness connectors as the probes may
damage the connectors upon insertion.
