DO NOT REMOVE OR DESTROY
2.
Check the drain pump and electrical connections by
performing the Drain Test under Manual Overview Test Mode
on page 9. The following steps assume that this step was
unsuccessful.
3.
Unplug washer or disconnect power.
4.
Remove console to access main control.
5.
Visually check that the J16 connector is inserted all the way
into the main control.
If visual check passes, go to step 6.
If connector is not inserted properly, reconnect J16 and repeat
step 2.
6.
Remove connector
J16
from main control. With an ohmmeter,
verify resistance values shown below across the following J16
connector pinouts:
Resistance should be 14–25
Ω
.
If values are open or out of range, go to step 7.
If values are correct, go to step 11.
7.
Tilt washer back to access drain pump. Verify pump is free
from obstructions.
8.
Visually check the electrical connections at the drain pump.
If visual check passes, go to step 9.
If connections are loose, reconnect the electrical connections
and repeat step 2.
9.
With an ohmmeter, check harness for continuity between
the drain pump and main control. See chart below.
If there is continuity, go to step 10.
If there is no continuity, replace the lower machine harness
and repeat step 2.
10.
With an ohmmeter, measure the resistance across the two
pump terminals. Resistance should be 14–25
Ω
.
If values are open or out of range, replace the pump motor.
If the resistance at the pump motor is correct, go to step 11.
11.
If the preceding steps did not correct the drain problem,
replace the main control.
a.
Unplug washer or disconnect power.
b.
Replace the main control.
c.
Reassemble all parts and panels.
d.
Plug in washer or reconnect power. Calibrate washer
and perform Quick Overview Test to verify repair.
TEST #8: Lid Lock
Perform the following checks if the washer does not lock
(or unlock).
1.
Perform the Lid Lock test under Manual Overview Test Mode
on page 9. The following steps assume that this step was
unsuccessful.
2.
Check lid lock mechanism for obstruction or binding. Repair
as necessary.
3.
Unplug washer or disconnect power.
4.
Remove console to access main control.
5.
Visually check that the J15 connector is inserted all the way
into the main control.
If visual check passes, go to step 6.
If connector is not inserted properly, reconnect J15 and
repeat step 1.
6.
Remove connector
J15
from main control. With an ohmmeter,
verify lid lock resistance values shown below across the
following J15 connector pinouts:
If resistance values are good, go to step 7.
If switch measurements do not match the values shown
in the table for unlocked (or locked) condition, a problem
exists in the lid lock. Replace the lid lock mechanism.
7.
If the preceding steps did not correct the lock problem,
replace the main control.
a.
Unplug washer or disconnect power.
b.
Replace the main control.
c.
Reassemble all parts and panels.
d.
Plug in washer or reconnect power. Calibrate washer
and perform Quick Overview Test to verify repair.
