Suddenly, my Kenmore Elite h3 washer door would not lock. I could hear a clicking noise in the back but no loud latching noise from the door. After a few clicks, the beeper would sound and the panel would flash "DL" and "F". After reading a few blogs I determined I had a door latch problem. I unplugged the washer and turned off the water. I tightened the screws for the latch in the door using a torx screw bit. I removed the front bottom panel (3 torx screws bottom of panel). Reached inside and pulled the emergency release (You can see it using a flashlight) several times. I then removed the top panel (3 hex screws in the back) and unplugged the 2 pink wireing harness from the panel in the back and plugged them back in (the pink wires go to the door latch). I also reached in and jiggled the wiring harness to door latch. Plugged the washer back, turned the water on, put a load of clothes and the door latch locked with it's usual loud noise and the washer started working!! I am going to buy a replacement door latch swithch. I found several on ebay for about 40 bucks.
