Answer to: Why is the "F dl" light come onI have a Kenmore H3 washer that was having intermittent door lock errors. I found this board postings very helpful. I first replaced the door switch. That seemed to help but it did not completely solve my problem. After reading the suggestions on this site I removed the washer top by unscrewing the 3 screws on the back of the unit (torx screws). I checked the (pink) wire connectors to the control unit at the top back of the unit. Several seemed loose and one in particular definitely audibly "clicked" as it was reseated. After this the washer works fine.
