TEST #11: Temperature Sensor
This test checks the temperature sensor,
wiring, and CCU.
1. Unplug washer or disconnect power.
2. Remove top panel to access machine
electronics.
3. Disconnect connector SET2 from the CCU.
Refer to CCU diagram on page 13.
4. Using an ohmmeter, measure the
resistance across pins 1 and 2 of temperature
sensor connector SET2. The measured
resistance should be within the temperature
range shown in the following table.
Approx. Temperature

32 0
50 10
68 20
86 30
104 40
122 50
140 60
158 70
176 80
194 90
 If the resistance is within the range shown
in the table, go to step 8.
 If the resistance is infinite or close to zero,
go to step 5.
5. Remove the back panel to access the
heating element.
6. Disconnect the temperature sensor
connector from the heating element. See
Figure 9.
7. Using an ohmmeter, measure the
resistance across pins 1 and 2 of the
temperature sensor (on the heating element).

DESTROY
 If the resistance is within the range shown
in the table, the sensor is good; replace the
lower main harness.
 If the resistance is open, replace the
temperature sensor.
8. If the preceding steps did not correct the
temperature sensor problem, replace the CCU.
 Unplug washer or disconnect power.
 Replace the CCU.
 Reassemble all parts and panels.
 Perform the "Quick Diagnostic Test"
on page 6 to verify repair.
TEST #12: Dispenser
Distribution System
Perform the following checks if the washer will
not dispense detergent, bleach, or fabric softener.
1. Check water supply to washer. Check water
hose connections to and inside the washer.
2. Verify dispenser drawer is not clogged
with detergent.
3. Unplug washer or disconnect power.
4. Remove the top panel to access the
machine electronics.
5. Check the mechanical linkage from
dispenser motor to top of dispenser.
6. Visually check that the DI6 connector is
inserted all the way into the CCU. Refer to
CCU diagram on page 13.
 If visual check passes, go to step 7.
 If connector is not inserted properly,
reconnect DI6 and retest.
7. Remove connector DI6 from the CCU.
With an ohmmeter, verify the resistance
values shown below across the following
DI6 connector pinouts.

Motor
 If the motor resistance is good, go to step 8.
 If the measurement does not match
the value shown in the chart, check the
harness and connections between the CCU
and dispenser motor for continuity. If the
harness and connections are good, replace
the dispenser motor.
