FOR SERVICE TECHNICIANS ONLY
9. Check if shifter assembly is affecting the
main control DC supplies.
a. Unplug washer or disconnect power.
b. Remove connector J2 from main control.
c. Plug in washer or reconnect power.
d. Recheck the DC voltages per steps 7 & 8.
If the DC voltages return, replace shifter assy.
If one or more DC voltages are still missing,
go to step 10.
10. Check if console UI is affecting the main
control DC supplies.
a. Unplug washer or disconnect power.
b. Remove connector J9 from main control.
c. Plug in washer or reconnect power.
d. Recheck the DC voltages per steps 7 & 8.
Perform voltage checks inside header J9 on the
board – do not short pins together .
If the DC voltages return, replace console UI.
If one or more DC voltages are still missing,
go to step 11.
11. Main Control has malfunctioned.
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 #2: Valves
This test checks the electrical connections
to the valves, and the valves themselves.
1. Check the relays and electrical connections
to the valves by performing the Cold, Hot, Oxi,
and Fabric Softener Valve tests under Manual
Test Mode. Each test activates and
deactivates the selected valve. The following
steps assume one (or more) valve(s) did not
turn on.
2. For the valve(s) in question check the
individual solenoid valves:
a. Unplug washer or disconnect power.
b. Remove console to access main control.
c. Remove connector J3 from main control.
Refer to main control diagram.
d. Check harness connection to solenoid valves.
3. Check resistance of the valve coils across
the following J3 connector pinouts:
Resistance should be between 890–1.3k Ω .
If resistance readings are tens of ohms
outside of range, replace the valve assembly.
If resistance readings are within range,
replace main control and calibrate washer.
Perform automatic test to verify repair.
TEST #3a: Drive System – Shifter
This test checks connections, shifter motor,
switch, and optical sensor.
NOTE: Refer to Figure 4, “Shifter Assembly Strip
Circuit” on page 14 for tests and measurements.
IMPORTANT: Drain water from tub before
accessing bottom of washer.
Functional Check:
1. Check the shifter and electrical connections
by performing both the Spin AND Agitate test
under Manual Test Mode. The following
steps assume that this step was unsuccessful.
2. Unplug washer or disconnect power.
3. Check to see if basket will turn freely.
If basket turns freely, go to step 4.
If basket does not turn freely, determine what
is causing the mechanical friction or lockup.
4. Remove console to access main control.
5. Visually check that the J2 and J16 connectors
are inserted all the way into the main control.
If visual checks pass, go to step 6.
If connectors are not inserted properly,
reconnect J2 and J16 and repeat step 1.
Shifter Motor:
6. .l o rt n o c ni a m m o rf 6 1 J r o tc e n n o c e v o m e R
With an ohmmeter, verify resistance values shown
below across the following J16 connector pinouts:
Resistance should be between 2k to 3.5k Ω .
If values are correct, reconnect J16 and
proceed to step 7.
If values are open or out of range,
go to step 13.
7. Plug in washer or reconnect power.
8. With a voltmeter set to AC, connect the
black probe to J16-2 (N) and red probe to
J16-1 (L1). Activate shifter motor by switching
between Spin and Agitate modes. Energize
outputs using Manual Test Mode.
