i'm sure this has been asked before, so I apologize. My spin cycle stopped working with an error code of F7 E1. I replaced the belt and pulley and it worked for a few days. While running a clean washer, Affresh cycle A blood curdling, high pitched grinding noise let out. Now when I hit start, it pauses for a few seconds (lid locks) then lets out the same grinding noise, repeating every few seconds. I was told to replace the shift actuator. after doing that the problem remains. Does anyone have experience with any other way to fix this? Thank you for help.
