5. Tilt machine 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 Lid Lock
Resistance table below:
LID LOCK RESISTANCE

35 Ω 35 Ω

Lid Closed = 0 Ω

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.

ACCESSING & REMOVING THE
ELECTRONIC ASSEMBLIES
There are two electronic assemblies; the machine/motor
control assembly and the user interface assembly. See
figures 3 and 4 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
3. Remove the wire connection to the user inter face
assembly.
4. Remove the wash cycle selector knob by firmly
pulling on it.
5. The user interface assembly is held to the console
insert panel by three screws and two locking tabs.
After the screws are removed, lift each of the
locking tabs to remove the back cover of the user
interface assembly.
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
Measured
1. Refer to preceding removal sections and replace in
P12-2 P12-3
reverse order.
2. Plug in washer or reconnect power.
P12-4
NOTE: When reconnecting wire connections, route wires
as shown in figure 3, page 15. Be sure to route wires
P12-1 P12-7
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
P12-5
tray when reassembling top.
NOTE: Ensure the console gasket is in place when
reinstalling the console.
