So I'm asking you what
Hi
Thanks for using FixYa and I am sorry to hear whatever happened. Error F 51 flashes when there is a motor
rotor position sensor (RPS) failure. With that being said it seems that this
issue should have been checked earlier itself by the two tech. guys that came
to your house. Please follow the step by step instructions to resolve this
issue: 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, determine what
is causing the mechanical friction or lock up.
4. Remove the console to access the machine/ motor
control assembly.
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. 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. Remove the motor bolt, then the motor
cover to access the motor connections.
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. With an ohmmeter, check
for continuity between all pins on the P10 machine/motor control connector and
the motor rotor position sensor (RPS) connector. 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.
Please do accept the solution if
the issue is resolved or else revert for further assistance.
Thanks
