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 Automatic 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
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 Automatic Test to verify repair.
