TROUBLESHOOTING TESTS

TEST #1 Supply Connections
This test assumes that proper voltage is pres-
ent at the outlet.
1. Unplug washer or disconnect power.
2. Access the machine/motor control as-
sembly. See Accessing & Removing the
Electronic Assemblies.
3. With an ohmmeter, check for continuity
between the neutral (N) terminal of the
plug and P13-1 on the machine/motor
control. See Figures 3 and 4, page 6-16.
• If there is continuity, go to step 4.
• If there is no continuity, replace the
power cord.
4. In a similar way, check the continuity be-
tween the L1 terminal of the plug and
P13-3 on the machine/motor control. See
Figures 3 and 4, page 6-16.
•
If there is continuity, go to step 5.
• If there is no continuity, replace the
power cord.
5. Visually check that the P10 connector is
inserted all the way into the machine/mo-
tor control.
6. Visually check that the user interface as-
sembly is properly inserted into the front
console.
7. If both visual checks pass, replace the
user interface assembly. See Reinstall-
ing the Electronic Assemblies.
8. Plug in washer or reconnect power.
9. Activate the Console and Indicators Di-
agnostic Test mode to verify repair.
10. If indicators still do not light, the machine/
motor control has failed:
• Unplug washer or disconnect power.
• Replace the machine/motor control as-
sembly.
• Plug in washer or reconnect power.
