15. Test Motor Run Capacitor.
NOTE:
A faulty
capacitor may cause the motor to “hum”, not
start, or turn slowly.
a. Disconnect one wire terminal from the capacitor.
b. Discharge capacitor by placing a resistance
across the terminals.
c. With an ohmmeter, measure across the
terminals and note reading.
If a steady increase in resistance is noted,
continue to step 16.
If the capacitor is either shorted or open,
replace capacitor, calibrate, and repeat step 1.
16. If the preceding steps did not correct the
motor 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 #4: Console and Indicators
Console and Indicators Check:
This procedure checks the cycle selector
knob, indicators, buttons, beeper, and if it
exists—the 7-segment display.
1. Plug in washer or reconnect power.
2. To access UI (User Interface) Test Mode,
perform steps 1 and 2 of Activating the
Service Diagnostic Modes. Turn
the cycle selector knob until the display or
status LED’s correspond as follows:
“Rinse & Spin” LED On, “
06
” Displayed
on 7-segment
06
Sensing Soak Wash Rinse Spin Done
Press the START button to begin the UI test.
Upon entering the UI test mode, all LED’s
and display (if it exists) will be turned ON.
Pressing the POWER button will deactivate
the UI test mode.
Pressing the START button will toggle the
display, start, and status indicators on and off.
When rotating the cycle selector knob,
each click “indent” toggles the “Done”
LED as well as the associated cycle LED.
Pressing each button will toggle its
respective indicator(s) ON or OFF.
None of the indicators light up:
1. Unplug washer or disconnect power.
2. Access the console’s electronic assemblies
and visually check that the J9 connector is
inserted all the way into the main control.
3. Visually check that the user interface
assembly is properly inserted in the console.
4. If both visual checks pass, follow procedure
under TEST #1, “Main Control” to
verify supply voltages.
If supply voltages are present on the main
control, go to step 5.
If supply voltages are not present, replace the
main control and calibrate washer . Perform
Automatic Test to verify repair. Go to step 6.
5. Replace the user interface assembly.
6. Reassemble all parts and panels.
7. Plug in washer or reconnect power.
8. Follow procedure under TEST #4 , “ Console
and Indicators Check”, to verify repair.
Some buttons do not light indicators:
1. Unplug washer or disconnect power.
2. Access the console’s electronic assemblies
and visually check that the electronics and housing
assembly is properly inserted into the front console.
3. If visual check passes, replace the user
interface assembly.
4. Reassemble all parts and panels.
5. Plug in washer or reconnect power.
6. Follow procedure under TEST #4 , “ Console
and Indicators Check”, to verify repair.
No beep sound is heard (HE models):
1. Verify that cycle signal is set to either
“Soft” or “Loud.”
NOTE:
Pressing and holding
the cycle signal button for three seconds will
Enable/Disable the cycle signal.
2. Unplug washer or disconnect power.
3. Access the console’s electronic assemblies
and visually check that the J9 connector is
inserted all the way into the main control.
4. If visual check passes, replace the user
interface assembly.
5. Plug in washer or reconnect power.
6. Set Cycle Signal to either “Soft” or “Loud.”
Check for beep tone.
7. If beeper still does not emit a tone, the 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 procedure under TEST #4,
“Console and Indicators Check”, to verify repair.
