■

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 and Indicators. 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 in setting mode (plugged

in and power up just before running a cycle).

2. Select any one button (except POWER/CANCEL

and START/PAUSE) 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

8:88 showing in the Estimated

Time Remaining three-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 test sequence continues by checking 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

8:88 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.

Procedure

Warm water fills

through Fresh

valves, then

Fresh valve until

basket floats

(disengages);

then washer

continues filling

through Fresh

valves to

minimum water

level.

If no water, or fill

temperature is wrong, go

to Manual: Water Valves

test, page 2.

If basket does not float

or disengage, determine

cause of friction.

Cold water fills

through Bleach

valve for 10

seconds. Then,

Hot water fills

through Oxi valve

for 10 seconds.*

If no water in bleach or

Oxi cup, go to Manual:

Water Valves test, page 2.

Hot water fills

through Fabric

Softener valve

for 10 seconds.

If no water in fabric

Manual: Water Valves

test, page 2.

Warm water fills

through

for 10 seconds.

If no water in detergent

cup, go to Manual: Water

Heater turns on

for 5 seconds.

♦

Test the heater element

as described in

TEST #9, page 6.

Agitate for

15 seconds.

If no wash action, go to

Manual: Motor, Agitate

test; page 2.

Recirculate for

10 seconds.

If water is not being

recirculated, go to Manual:

Pumps test, page2.

Drain to basket

engaged plus

timed drain for

10 seconds.

If water is not draining,

go to Manual: Pumps

spin 23 rpm for

5 seconds, then

coast to 0 rpm.

If drain pump is not on,

go to Manual: Pumps

If basket is not turning,

go to Manual: Motor test,

page 2.

If basket does not stop

spinning within 10

seconds,pressPOWER/

CANCEL and restart test.

If no end of cycle beep,

make sure cycle signal

♦C5 will be displayed but no action will be taken on

non-heater models.

DIAGNOSTIC: Unsuccessful Entry

If entry into diagnostic mode is unsuccessful (see steps

1and2ofActivationofAutomatic DiagnosticTestMode,

at left), refer to the following indications and actions:

Indication 1: None of the indicators or display

turns on.

Action:

Press POWER/CANCEL 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,

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 part 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

lectrical Shock Hazard

Disconnect power before

servicing.

Replace all parts and

panels before operating.

Failure to do so can result

in death or electrical shock.

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?

■

Alltests/checks shouldbemadewithaVOM(volt-ohm-

milliammeter) or DVM(digital-voltmeter) havinga

sensitivity of 20,000 Ω per voltDCorgreater.

NOTE: Avoid using large diameter probes when

checking harness connectors as the probes may

damage the connectors upon insertion.

C2: A 10 second pause will be observed for models

without an Oxi dispenser.
