leads of a 20,000 Ω resistor to the two terminals.
b. Disconnect the wires from the capacitor
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 washer (page
4), and repeat step 1.
16. If the preceding steps did not correct the
motor problem, replace 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" on page 12 to
verify supply voltages.
 If supply voltages are present on the main
control, go to step 5.
 If supply voltages are not present, replace

6. Reassemble all parts and panels.
7. Plug in washer or reconnect power.
8. To verify repair, activate the Service
Diagnostic Mode, and then perform UI Test
Mode on page 4.
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

interface assembly.
4. Reassemble all parts and panels.
5. Plug in washer or reconnect power.
6. To verify repair, activate the Service
Diagnostic Mode, and then perform UI Test
Mode on page 4.
No beep sound is heard:
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. Perform
washer calibration on page 4. To verify repair,
activate the Service Diagnostic Mode, and then
