We have a whirpool top load Cabrio, It stops its cycle within

Resolved Question:

We have a whirpool top load Cabrio, It stops it's cycle within the first two minutes, flashes the letter "F" and then goes to flashing 50 and beeps. I've had this problem on and off since we purchased the machine. In the beginning I found that the installation company had not levelled it. I levelled it and the problem seemed to go away for a while. We have unplugged it thinking the smart board may need to re-set and I've checked it for being level.

Can you identify what the issue is?

Thank you,
John Laham

Hi....Bob here... I see you are having a problem with your washer..The f50 error code indicates a Stalled motor..Most common with this washer is a Rotor Position Sensor...The sensor monitors the rotation of the motor..

F50

(F50)

Motor Stalled F then 50 flashes when the motor rotor position sensor (RPS) senses no rotation.
Does basket turn freely? If not, make sure bottom shipping pack has been removed. Determine cause of friction.

You would need to have the sensor tested first hand with a test meter...Here is the first test procedure to do to determine the problem further..If you would like i can provide a downloading service manual...Also please do not forget to use the accept option before leaving today.If you have any further questions i will be standing by...Thanks Bob

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 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.
