There has been a few service bulletins posted for this model washer you have, This model is a Roper made by Whirlpool - Vertical Modular Washer. I'm going to post what SENSING does first, then you will need to locate your tech. data sheet and check for error codes and post what the error codes say.
When the START button is pressed, the washer will first perform a self-test on the lid lock mechanism. You will hear a click, the basket will make a slight turn, and the lid will unlock briefly before locking again. Once the lid has locked the second time, the washer
will slowly spin the dry load to estimate the load size, and begin adding water. The washer will then move the load briefly, pause to allow water to soak in to the load, and resume adding water. This process may repeat until the correct amount of water has been
added for the load. You may also hear water flowing through the dispenser, adding detergent to the load.
NOTE: The sensing light may also come on during the Soak and Wash portions of the cycle. This is normal.
Now I'm posting your Lid Lock Switch and the video of how to access and replace it, but I don't want you to replace the lid switch YET, unless you get an error code saying to replace it. The main reason I'm posting your lid lock switch and video is just to show you how to access your tech. data sheet.
Go into diagnostics and retrieve the codes, and clear them. This is very important since most complaints start with the lid lock on and blinking, or the unit will not start and spin.
If, when in diagnostics the codes are F7E1, F7E5, or motor speed codes, then chances are it is a motor, capacitor, or shifter related issue. Once the codes are cleared, put the washer into a manual diagnostic test and run the HEAVY AGITATION; if
after 15‐20 Seconds the motor runs then you can rule out the motor, capacitor, control, and most likely the wiring harness connections (although still check the BK wire from the shifter to the control). Remember, the timing wheel only turns in the
transmission during the spin cycle.
Next, while in Manual diagnostics, try to get the unit to spin; if the motor hums for a split second and then shuts down with the lid lock blinking; go back into diagnostic codes and look for shifter or speed sensor errors.
This is proof that the shifter/sensor assembly is the issue because the optical sensor is not reading the motor speed.
