Accessing & Removing The Electronic Assemblies - Whirlpool Cabrio W10026634B Manual

FOR SERVICE TECHNICIAN ONLY – DO NOT REMOVE OR DESTROY
TEST #7 Drain/Recirculation
Perform the following checks if washer fails to drain or
recirculate.
1. See Activation of Manual Diagnostic Test Mode,
page 2 and perform the Manual: Pumps test.
2. Remove the console to access the machine/motor
control assembly. See Accessing & Removing the
Electronic Assemblies, page 6.
3. Visually check that the P4 connector is inserted all
the way into the machine/motor control.
If visual check passes, go to step 4.
If visual check fails, reconnect P4 and repeat step 1.
4. Remove connector P4 from the machine/motor
control and check resistance values of pump motor
windings. Resistance values should match those
shown in wiring diagram, page 16.
If resistance values are good, go to step 7.
If winding measurements are much higher (tens
of ohms to infinity) than shown in wiring diagram,
a problem exists in the pump motor winding or
in the connection between the machine/motor
control and the pump. Go to step 5.
5. Tilt washer forward to access the bottom of the
machine and the pumps. See figure 1, page 14.
6. Check the resistance at the pump motor. Remove
the connector at the motor and take measurements
across pump terminals. Measurements should be
as shown in the wiring diagram.
If winding measurements are much higher (tens
of ohms to infinity) than shown in wiring diagram,
replace the pump motor.
If the resistance at the pump motor is correct,
there is an open circuit in the wiring between the
motor and the machine/motor control. Repair or
replace the lower wiring harness.
If the pump motor windings and machine/motor
control check OK, repair or replace the pump. Be
sure to check the pump and tub sump for foreign
objects before replacing pump.
7. See Activation of Manual Diagnostic Test Mode,
page 2 and perform the Manual: Pumps test.
8. If the Manual: Pumps test failed, then the
machine/motor control has failed:
Unplug the washer or disconnect power.
Replace the machine/motor control assembly.
Perform the Manual: Pump test on page 2.
TEST #8 Lid Lock
Perform the following checks if washer fails to lock
(or unlock).
1. Perform Manual: Lid Switch and Manual: Lid Lock
tests on page 2.
2. Remove the console to access the machine/motor
control assembly. See Accessing & Removing the
Electronic Assemblies, at right.
3. Visually check that the P12 connector is inserted
all the way into the machine/motor control.
If visual check passes, go to step 4.
If visual check fails, reconnect P4 and repeat step 1.
4. Check the lid lock motor winding and switches by
removing P12 from the machine/motor control and
checking the resistance values shown in the
following Lid Lock Resistance table:

If resistance values are good, go to step 5.
If switch measurements do not match the values
shown in the table for unlocked (or locked)
conditioned, a problem exists in the lid lock.
Replace the lid lock.
5. If the Manual: Lid Switch or Manual: Lid Lock tests
in step 1 failed, the lock may be stuck or the lock
is defective.
Unplug washer or disconnect power.
Replace Lid Lock Assembly.
Repeat the Manual: Lid Switch and Manual: Lid
Lock tests on page 2 to verify repair.
TEST #9 Heater Element
Perform the following checks to ensure the heater is
functioning properly.
1. Unplug washer or disconnect power.
2. Remove the heater terminal plastic cover. See
figure 3, page 14.
3. Check the connection to the water heater element.
4. Check resistance of heater element if present on this
model (abnormal = infinity).
5. If resistance is infinite, replace heater element and
reinstall heater terminal plastic cover.
6. Using an ohmmeter, measure continuity between all
pins on the P8 connector and the heater relay board.
Repeat this step for connector P3.
7. If connections are correct, replace the heater relay
board.
8. If problem persists, replace the machine/motor
control assembly.
ACCESSING & REMOVING THE
ELECTRONIC ASSEMBLIES
There are two electronic assemblies; the machine/motor
control assembly and the user interface assembly. See
figures 4 and 5 on page 15.
Accessing the Electronic Assemblies
1. Unplug washer or disconnect power.
2. Remove three screws from the rear of the console
assembly. Pull console towards front of washer to
hinge open and/or remove console.
Removing the Machine/Motor Control
Assembly
3. Remove all the wire connections to the
machine/motor control.
4. Remove the one screw holding the machine/motor
control assembly to the console tray.
5. There are two plastic legs on the rear of the
machine/motor control assembly that fit into the
console tray. Lift the front of the control assembly
to pivot it out from the console tray.

Removing the User Interface Assembly
Contacts 3. Remove the wire connection to the user inter face
Measured
assembly.
4. Remove the wash cycle selector knob by firmly
P12-2 P12-3
pulling on it.
5. The user interface assembly is held to the console
P12-4
insert panel by three screws and two locking tabs.
After the screws are removed, lift each of the
P12-1 P12-7
locking tabs to remove the back cover of the user
interface assembly.
P12-5
6. Remove the wash cycle selector switch from the
user interface assembly opening by lifting the
locking tab on the wash cycle selector switch and
turning the selector switch in a counterclockwise
direction.
7. Three locking tabs located at the bottom of the
console insert panel secure the user interface
assembly to the console insert panel. Using a
flat-blade screwdriver, gently apply pressure to
the locking tabs to release the user interface
assembly.
Reinstalling the Electronic Assemblies
1. Refer to preceding removal sections and replace
in reverse order.
2. Plug in washer or reconnect power.
NOTE: When reconnecting wire connections, route wires
as shown in figure 4, page 15. Be sure to route wires
beneath the retainer clips on the machine/motor control,
and ensure user interface assembly wire does not get
pinched between the console assembly and the console
tray when reassembling top.
NOTE: Ensure the console gasket is in place when
reinstalling the console.
