I got this solution a long time ago but didn't try it until now but IT WORKED! The directions I had said: Replace MCU. Drive motor control board located in the rear of the washer adjacent to the drive motor on the left hand side (facing from the rear with the back panel removed. The wiring harness can also cause the error but not as common. Go to Kenmore.com. First try and take the wiring harness off and then reconnect it to see if error code goes away if it doesn't replace the part. So we got to the panel and made sure all the plugs were tightened and it worked.
I had the same problem......the door lock needs to be changed or it's your computer. We already changed the door lock......remember to close it gentle............if you take the ltop off the machine (if the computer is the prob) you can pull up on the computer while it is flashing dl f (door lock failure) it will click the door lock closed/opened. I hope it helps!!!

F11 means Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly. I work with electronic based equipment often and have noted over the
years that harness connections on equipment that vibrates moderately
tends to loosen their connections over time. I therefore approached
this problem with this in mind. I completely tore down the entire unit,
carefully checking each and every component as I went. In all, I found
nothing out of the ordinary. I therefore took measures often required
of electronic equipment at work. I used a pick to pry the metal prongs
on the wire harness connections so that they would more tightly contact
the control board.
If you remove the tip cover of the washing machine the control board
can be found right in the back, center at the top of the machine.
Remove the harness connectors one at a time and carefully exercise the
connections toward one another to reduce the gap between them. Keep in
mind not to tighten to the point that there is not a gap between them.
Remember that these must slide over the edge of the board without
becoming distorted, bent or broken.
Step #1 of course should be to limit or reduce the vibration of your
machine as much as you are able. Make sure the machine (and floor) is
level. There have been some good postings about the use of rubber mats
that can be purchased from your local stores and placed underneath of
the machine feet.
Step #2 would then be to tighten the connections of the wire harness. Disconnect power! Use extreme caution!
Be advised that I would never tell anyone to jump into this if one does
not know what they are doing. Failing to work on any type of equipment
can be dangerous or even fatal if one is not familiar with Safe Work
Practices, such as disconnecting power cords and checking that the
power source IS disabled. Find someone you know who does well with this
type of work and let him/her perform the task for you. If this isn't
possible, call for the technician. Keep yourself safe at all costs.
After all, it's only a washing machine. Your life and limb is worth
much more than this!
"dL" indicates Door Lock Failure: dL flashes if the following conditions occur: Door lid is not closed completely due to interference. Wash media buildup is preventing the lock bolt from extending. Machine/motor control detects open door lid switch when attempting to lock. Machine/motor control cannot determine if door lock is in a locked state. Check for lock interference with lid or lock bezel
