DANGER
Electrical Shock Hazard
Only authorized technicians should perform
diagnostic voltage measurements.
After performing voltage measurements,
disconnect power before servicing.
Failure to follow these instructions can result in
death or electrical shock.

TEST #3 Drive System

Pre-Test Procedure
1. Activate Service Diagnostic Test Mode, retrieve any fault/
error codes, and clear them. If the displayed error codes
are F7E3, F7E4, F7E5, F7E6, F7E7, F7E9, there is likely a
motor or shifter related issue.
2. Once the error codes are cleared, enter Service Test Mode
and run the Fast Agitate test; if the motor runs after
15–20 seconds, there is not a problem with the motor,
control, or motor wiring harness connections.
3. While in Service Test Mode, try to get the washer to spin;
if the motor hums briefly and then shuts down, go to Fault
Code Display Mode and check for fault codes.
TEST #3a: Drive System – Shifter
This test checks connections, shifter coil, and harness.
NOTE: Lid must be closed and locked for the motor to agitate
or spin.
IMPORTANT: Whenever the washer is tilted for service or
troubleshooting, drain water from the basket, remove any
load items in the basket, and, if equipped, remove bulk
dispense drawer.
Functional Check:
1. Check the shifter and electrical connections by performing
both the Spin and Agitate tests under Service Test Mode
on page 2-4. The following steps assume that this step
was unsuccessful.
2. Unplug washer or disconnect power.
3. The motor and shifter should be able to be turned
independently of each other. If they are locked together,
there is a shifter slider issue. Proceed to step 12.
NOTE: Rotating the impeller quickly can cause the UI to
attempt to power up, and may cause audible feedback
and the main control to power up and apply braking
torque to the impeller.
¾ If basket and impeller turn freely, go to step 4.
¾ If basket and/or impeller do not turn freely, determine
what is causing the mechanical friction or lockup.
For Service Technician Use Only
4. Remove console to access main control.
5. Visually check that the J4 connector is inserted all the way

repeat step 1.
6. Plug in washer or reconnect power.
7. With a voltmeter set to AC, connect the black probe to
J4-1 (N) and red probe to J4-7 (L1). Activate shifter motor
by commanding Spin (ON) or Agitate (OFF) in Service Test
Mode.
