Customer Questions and Answers for Rotor Position Sensor by Whirlpool

Tim, based on the information provided, the most likely cause of failure would be the main control W11400681 if the lid locks properly and if there is not an error code identified through the diagnostic mode.

Mike, While the suspension rods and springs may look good, they are the most likely cause for the unit to get the UL code.

Al, if the washer is able to operate in a drain and spin cycle properly, the drive shaft would need to be inspected for corrosion where the basket sits. If there is corrosion, the drive shaft and bearing kit W10435302 would need to be replaced.

Larry, the loud sound similar to a jet engine would be caused by the bearings W10435302 failing. This can cause the perception of the basket spinning faster than normal.

Hello Ken, the control board has a faulty drain relay however the control board is no longer available from the manufacturer.WPW10189966.

Phillip, it would be recommended that the unit is placed into manual test mode and the fill test ran until it has reached a proper fill level. From there, the manual drain test would be operated to see if the inner basket catches and then suddenly drops (basket may need to be wiggled) when the water has completely emptied. If the spin basket does drop down suddenly, the failure would be in the driveshaft, requiring the bearing and tub seal kit W10435302 be replaced.

PB, This could be the suspension rods that are faulty and causing the unit to get off balance.

Hello Al, the fault code F51 code indicates the control board is not detecting the drive motor RPS (Rotor Position Sensor) sensor WPW10178988, this could be caused by a faulty sensor or a lower wire harness problem WPW10137697.

Denise, This error will most likely be caused by a faulty RPS sensor.

Hello Vaughn, first try to rotate the inner tub manually, it should rotate easily, if not check if the rotor has come loose or did a cloth get under the basket and prevents rotation. This model has several fault codes for almost every component, it also came with a technical test sheet located in the control panel area.
