TEST #3 Motor Circuit
 
This test checks the wiring to the motor and rotor position sensor; and the motor and rotor position sensor themselves.
 
NOTE: Drain water from tub.
 
1. See Activation of Manual Diagnostic Test Mode, and check the motor and electrical connections by performing the Spin test under Manual: Motor.
ACTIVATION OF MANUAL DIAGNOSTIC TEST MODE
1. Carefully read and perform steps 1 and 2 under Activation of Automatic Diagnostic Test Mode, and press the same button once during the 5 second display time of the 88.
NOTE: If the button is not pressed within 5 seconds, the Automatic test will start
(after saved fault codes).
6-6
2. If done successfully, a single beep occurs and the two-digit display shows the control ID# for 3 seconds, then displays 00 and the Add A Garment indicator LED
flashes.
Manual: Motor Rotor Position Sensor (RPS): Uses Wash, Rinse and Spin indicators to detect the three hall sensors. Console may have up to two of these indicators on at one time when the basket is not moving. Open door and rotate basket by hand.
The Wash, Rinse and Spin status indicators should toggle on and off according to direction the basket is being turned. If none of these indicators are on go to
TEST #3.
Spin: To activate Spin, door must be closed with door lock enabled. See Manual: Door Lid Lock.
NOTE: If door is not closed, an invalid button press beep will occur when performing next step.

NOTE: Indicators above button scroll from top to bottom.
• If motor fails to spin, go to TEST #3.
Agitate: Water must cover the wash plate (or agitator vanes) to ensure the basket is floating prior to agitation. Enabling agitation without enough water may cause a fault condition to occur.

NOTE: Indicators above button scroll from top to bottom.
• If motor fails to agitate, go to TEST #3.

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 lock up.
 
4. Remove the console to access the machine/motor control assembly. See Accessing & Removing the Electronic Assemblies.
 
5. Visually check that the P5 and P10 connectors are inserted all the way into the machine/motor control.
 
If visual checks pass, go to step 6.
 
If visual checks fail, reconnect P5 and P10 and repeat step 1.
 
6. Visually check that the P5 and P10 connectors are inserted all the way into the machine/motor control.
 
With an ohmmeter, verify resistance values as shown below:

7. Tilt machine forward to access the bottom of the machine and the drive motor area. See Figure 1 on page 6-13. Remove the motor bolt, then the motor cover to access the motor connections. See Figure 2 on page 6-13.
 
8. Visually check the mounting bracket and electrical connections to the motor and rotor position sensor board.
 
If visual check passes, go to step 9.
 
If visual check fails, reconnect the electrical connections, reassemble stator and motor cover and repeat step 1.
 
9. With an ohmmeter, check for continuity between all pins on the P10 machine/motor control connector and the motor rotor position sensor (RPS) connector. See Figures 2 and 4, pages 6-13 and 6-16.

If there is continuity, check the motor windings. If the windings are open, replace the drive motor.
 
If there is no continuity, replace the lower machine harness.
 
10. With an ohmmeter, check for continuity between all pins on the P5 machine/motor control connector and the drive motor connector. If there is continuity, replace the drive motor.
 
If there is no continuity, replace the lower machine harness.
 
11. The drive motor and lower harness are good. Replace the motor RPS board and perform the Diagnostics test in step 1 to verify repair.
 
12. If the Diagnostics motor test in step 1 failed, then the machine/motor control has failed:
 
Unplug the washer or disconnect power.
 
Replace the machine/motor control assembly.
 
Perform the Motor Diagnostics in step 1 to verify repair.

If visual checks pass, go to step 6.

If visual checks fail, reconnect P5 and P10 and repeat step 1.

6. Visually check that the P5 and P10 connectors are inserted all the way into the machine/motor control.

If there is continuity, check the motor windings. If the windings are open, replace the drive motor.

If there is no continuity, replace the lower machine harness.

10. With an ohmmeter, check for continuity between all pins on the P5 machine/motor control connector and the drive motor connector. If there is continuity, replace the drive motor.

If there is no continuity, replace the lower machine harness.

11. The drive motor and lower harness are good. Replace the motor RPS board and perform the Diagnostics test in step 1 to verify repair.

12. If the Diagnostics motor test in step 1 failed, then the machine/motor control has failed:

Unplug the washer or disconnect power.

Replace the machine/motor control assembly.

Perform the Motor Diagnostics in step 1 to verify repair.
