TEST #2 Log Valve
This test checks the electrical connections to
the valves, and the valves themselves.
1. Check the relays and electrical connec-
tions to the valves by performing the steps
under Diagnostic: Manual, then Manual:
Water Valves. Each step in the test ac-
tivates a group of valves. The following
steps assumes one (or more) valve(s)
failed to turn on.
2. For the valve(s) in question check the in-
dividual solenoid valves:
• Unplug washer or disconnect power.
• Disconnect connector P1 and P2 from
the machine/motor control.See Figure
4, page 6-16.
• Check harness connection to solenoid
valves.
3. Check resistance of valve coils at con-
tacts P1 and P2 shown in the Wiring Dia-
gram on page 7-1. Resistance values
should match those shown.
• If resistance readings are tens of ohms
outside of range, replace the entire log
valve assembly.
• If resistance readings are within range,
replace the machine/motor control as-
sembly.
4. Reconnect connectors P1 and P2 to the
machine/motor control.
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 Agitate
and Spin tests under Manual: Motor. The
following steps assumes that this step
failed.
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, deter-
mine what is causing the mechanical
friction or lock up.
4. Remove the console to access the ma-
chine/motor control assembly. See Ac-
cessing & Removing the Electronic As-
semblies.
5. Visually check that the P5 and P10 con-
nectors 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. With an ohmmeter, check for 16 ohms
resistance at the P5 connector between
pins P5-1 and P5-2, and also between
pins P5-1 and P5-3. Also measure the
resistance at the P10 connector between
pins P10-1 and P10-7 and verify that the
resistance is within the range shown in
the wiring diagram on page 7-1.
• If the resistance is correct, go to step 11.
• If the P5 connector resistance is much
higher than 16 ohms, or the P10 con-
nector resistance is out of range, go to
step 7.
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 ac-
cess 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 elec-
trical connections, reassemble stator
and motor cover and repeat step 1.
