Answer to: Why is the "F dl" light come on-same thing... mine would not lock, error 'DL'... i replaced the door latch mechanism, which did not solve the problem. -i removed the three torx screws from the top-back of the unit, lifted the back cover up gently an inch, and slid the top of the washer away from me, removed top. -then i just reseated the pink wire connector (i reseated them all). -problem solved, for now. -must be a poor connection (vibration?). -cost me $73 for the latch i didn't need, hope i save you $. -update 1/20/18: -eventually i had to re-solder the board where the connectors make contact, which involved removing the board and adding a bit of solder to each of the contact points on the board, been years now without a fault.
