Code f50 is what?
The F50 error code indicates that the RPS (rotor position sensor) detects no motor rotation. Check to see if the basket spins freely. If not, you could have an item caught between the outer tub and the inner spin basket. A toy or other item underneath the washer could also prevent the basket from spinning and would result in this F50 code.
If the basket spins freely, you could have a wiring failure that would prevent the motor from spinning.
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 stepfailed.
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. 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 connector
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 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, go to step 11.
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.
