IMPORTANT
Circuits é lectroniques sensibles
aux dé charges é lectrostatiques
IMPORTANT
Le risque de décharge électrostatique est permanent. Une
décharge électrostatique peut endommager ou affaiblir les
composants électroniques. La nouvelle carte peut donner
l’impression qu’elle fonctionne correctement après la
réparation, mais une décharge électrostatique peut lui avoir
fait subir des dommages qui provoqueront une défaillance
plus tard.
Utiliser un bracelet de décharge électrostatique. Connecter
le bracelet à la vis verte de liaison à la terre ou sur une surfac
métallique non peinte de l’appareil
-OUToucher plusieurs fois du doigt la vis verte de liaison à la
terre ou une surface métallique non peinte de l’appareil.
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
-ORTouch 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.
Avant de retirer la pièce de son sachet, placer le sachet
antistatique en contact avec la vis verte de liaison à la terre ou
une surface métallique non peinte de l’appareil.
É viter de toucher les composants électroniques ou les
broches de contact; tenir la carte de circuits électroniques
par les bords seulement lors des manipulations.
Lors du réemballage d’une carte de circuits électroniques
défaillante dans le sachet antistatique, appliquer les
instructions ci-dessus.
DIAGNOSTIC GUIDE
GUIDE DE DIAGNOSTIC
Before servicing, check the following:
Avant d’entreprendre une réparation, contrô ler ce qui suit :
Vérifier que la prise de courant est alimentée.
Fusible grillé ou disjoncteur ouvert? Fusible temporisé grillé?
Make sure there is power at the wall outlet.
Has a household fuse blown or circuit breaker tripped? 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 or DVM having a
sensitivity of 20,000 ohms per volt DC or greater.
Check all connections before replacing components. Look for
broken or loose wires, failed terminals, or wires not pressed into
connections far enough.
A potential cause of a control not functioning is corrosion 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 power cord unplugged from
outlet, and with wiring harness or connectors disconnected.
PART NO. 46197042905
Robinets d’eau chaude et d’eau froide ouverts et tuyaux d’arrivée
d’eau exempts d’obstruction?
Utiliser pour tous les contrô les un voltmètre ou autre instrument
dont la résistance interne est de 20 000 ohms par volt CC
ou plus.
Contrô ler toutes les connexions avant de remplacer un composant.
Rechercher des fils brisés ou mal connectés, ou des bornes ou
cosses de connexion détériorées.
Le non-fonctionnement d’un organe de commande peut être dû à la
corrosion des pièces de connexion. Inspecter les connexions et contr
ler la continuité avec un ohmmètre.
Connecteurs : Examiner le sommet d’un connecteur; rechercher
des fils brisés ou mal connectés; rechercher également des cosses
mal branchées.
Lors de toute mesure de résistance, vérifier que le cordon
d’alimentation est débranché de la prise de courant, et que le
faisceau de câblage ou le connecteur est débranché.

TROUBLESHOOTING GUIDE
NOTE: After problem(s) are fixed, please run the diagnostic test to ensure that there have no other issues.
PROBLEM
POSSIBLE CAUSE/TEST
WON'T POWER UP
1. Check that the unit is plugged into a working outlet and for blown fuses.
2. Check for power going to Central Control Unit (CCU) by listening for a click in the CCU when unit is plugged in. If no

NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH TRIP NOT DETECTED
Water level is not reached within a defined time in normal wash cycle.
Possible Causes/Procedure
„ If there is no water in the unit:
– Make sure that both valves at the water source(s) are turned on all the way.
– Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.
– Verify inlet valve operation.
„ If there is water in the unit:
– Verify drain pump operation.
– Remove hose from pressure switch. Dislodge any debris build up in the hose inside the outer tub.
– Verify that the pressure switch hose is in good condition and properly connected to tub and pressure switch.
1. Verify there is not a siphon problem.
2. Unplug washer or disconnect power.
3. Verify wire harness connections to inlet valves, pressure switch, drain pump and Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power
6. Verify pressure switch operation.
7. Verify CCU operation by running a Quick Diagnostic Test or any cycle

Water level is not reached within a variable time (EEPROM parameter) in whirlpool factory test
Possible Causes/Procedure
„ If there is no water in the unit:
– Make sure that both valves at the water source(s) are turned on all the way.
– Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.
– Verify inlet valve operation.
„ If there is water in the unit:
– Verify drain pump operation.
– Verify that the pressure switch hose is in good condition and properly connected to tub and pressure switch.
– Remove hose from pressure switch. Dislodge any debris build up in the hose inside the outer tub.
1. Verify there is not a siphon problem.
2. Unplug washer or disconnect power.
3. Verify wire harness connections to inlet valves, pressure switch, drain pump and Central Control Unit (CCU).
4. Check all hoses for possible leaks.
5. Plug in washer or reconnect power
6. Verify pressure switch operation.
7. Verify CCU operation by running a Quick Diagnostic Test or any cycle
F02
OVERFLOW CONDITION
Overflow level has been reached, and last for more than 2 seconds. In an overflow condition, the door remains locked and
the drain pump runs constantly, and after 10 minutes, door will be unlocked in order to cut off the valves power. Then if
overflow still happens, start pump again. Turn off hot and cold water faucets and unplug the unit before servicing.
Possible Causes/Procedure
1. Check the drain hose and make sure it is not plugged or kinked.
2. Unplug washer or disconnect power, if water still flows into the washer, replace the water valve.
3. Check wire harness connections to the drain pump, pressure switch, water inlet value, and Central Control Unit (CCU).
4. Check/clean drain pump filter of foreign objects.
5. Check for drain pump failure.
6. Check the inlet valve for proper shut off.
7. Check the pressure switch for proper operation.
8. Remove hose from pressure switch. Dislodge any debris build up in the hose inside the outer tub. Debris in side the hose
will not allow the switch to sense a pressure change.
F03
LONG DRAIN
If the drain time exceeds 4 minutes the water valves turn off. Only in factory test.
NOTES: Rotate knob to clear the display.
Possible Causes/Procedure
1. Turn washer ON to verify pump operates.

SUDS LOCK (OVERDOSE OF DETERGENT
DETECTED DURING THE WASH CYCLE)
If suds are detected continuously by the pressure switch during drain or spin, washer will enter Suds Detection mode. The
washer will fill with 3/4 gallon (2.67 Liters) of water, then rest for 10 minutes with no tumbling. Washer will then drain. If
error occurs during spin cycle, the unit will then start spinning.
Possible Causes/Procedure
„
If too much detergent was used:
– Run the unit through a RINSE/SPIN cycle.
– Run a NORMAL cycle without adding any detergent.
„
This should clear the unit of the excess detergent.
1. Check the drain hose and make sure it is not plugged or kinked.
2. Is the drain standpipe higher than 9 feet, This can cause pump cavitations resulting in same failure code.
3. Unplug washer or disconnect power.
4. Check wire harness connections to the drain pump, pressure switch, and Central Control Unit (CCU).
5. Check/clean drain pump filter of foreign objects.
6. Plug in washer or reconnect power.
7. Check drain pump.
8. Check the pressure switch and pressure switch hose.
