TEST #2 Log Valve
3.
Check to see if basket will turn freely.
This test checks the electrical connections to
the valves, and the valves themselves.
--
I. 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 PI and P2 from
the
machinelmotor control.See Figure
4, page 6-1 5.
Check harness connection to solenoid
valves.
3.
Check resistance of valve coils at con-
tacts
PI and P2 shown in the Wiring Dia-
gram on page 7-1. Resistance values
should match those shown.
If resistance readings are outside of
range, replace the entire log valve
as-
sem bly.
If resistance readings are within range,
replace the
machinelmotor control as-
sembly.
4.
Reconnect connectors PI and P2 to the
machinelmotor 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 Activating the 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.
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-
chinelmotor control assembly. See Ac-
cessing
& Removing the Electronic As-
semblies.
5. Visually check that the P5 and PI0 con-
nectors are inserted all the way into the
machinelmotor control.
If visual checks pass, go to step 6.
If visual checks fail, reconnect P5 and
PI 0 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.
If the resistance is correct, go to step 11.
If the resistance is much higher than
16 ohms, 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 6-12. Remove the
motor bolt, then the motor cover to ac-
cess the motor connections. See Figure
2 on page 6-12.
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.
9. With an ohmmeter, check for continuity
between all pins on the
PI 0 machinelmo-
tor control connector and the motor rotor
position sensor (RPS) connector. See
Figures
2 and 4, pages 6-12 and 6-1 5.
If there is continuity, go to step 11.
If there is no continuity, replace the
lower machine harness.
