Customer Questions and Answers for Rotor Position Sensor by Whirlpool

Steve, you will want to check to make sure the basket turns freely. If it doesn't turn freely, the bearings may not be properly aligned and can cause the unit to act in this way. The F51 error is for the rps sensor, but the basket hanging up can cause this error. The F70 is an overload error and can be influenced by the basket not rotating freely.

Hello David, I'm sorry but we will need to ask you to post a new question including the model number from your units' I.D. tag so we can provide an accurate diagnosis and recommend parts that can be guaranteed to work properly on your unit. Thank you for your patience and understanding in this matter.

Hello Benjamin. F then 51 flashes when there is a motor rotor position sensor (RPS) failure or lower harness problem. 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, page 2 and check the motor and electrical connections by performing the Spin test 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. 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. Visually check that the P5 and P10 connectors are inserted all the way into the machine/motor control. 7. Tilt washer forward to access the bottom of the washer 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. 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. ? If there is continuity, check the motor windings. If the motor windings are open, replace the drive motor. ? 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.

Hello Tim, You should run the diagnostic test mode and pull any fault codes that are stored in the control. This will point you in the right direction for a proper repair. The procedure is as follows: 1. Be sure the washer is in standby mode (plugged in with all indicators off) or in setting mode (plugged in and power up just before running a cycle). 2. Select any one button (except POWER/CANCEL and START/PAUSE) and follow the steps below, using the same button: a. Press/hold 3 seconds. b. Release for 3 seconds. c. Press/hold 3 seconds. d. Release for 3 seconds. e. Press/hold 3 seconds. If this test mode has been entered successfully, all indicators on the console are illuminated for 5 seconds with 8:88 showing in the Estimated Time Remaining three-digit display. If indicators do not display as described above, the press/hold/release procedure above may not have been performed within the time frame necessary for successful entry. Repeat step 2 to ensure this was not the cause. 3. The test sequence continues by checking for saved fault codes. If there are no saved fault codes, all indicators on the console will momentarily turn off, then turn back on with 8:88 displayed. After 5 seconds, the Automatic test begins.

Hello Susan. It sounds like the bearings have failed and will need to be replaced on the unit. You need to order part numbers W10435302 and W10447783 to repair the unit.

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.

Hello Jeremiah, This can be caused by the harness WPW10137697 to the RPS Assembly, the RPS Assembly WPW10178988, or the electronic control board WPW10299400.

Hello Jason. You will need to order W10193886 for the bearings and shaft needed.

Hello TTed. The model number will have to be verified on the units I.D. tag since the one listed came up invalid. This will be necessary to look up and specific parts such as the one you requested. Thank you for your patience and understanding in this matter. We will need your model number to help you with this. Please call 1-877-477-7278 or post your model number with a new question on the parts page. Here is a link to help you locate it. http://www.appliancepartspros.com/modelnumber_locator.aspx
