As indicated in those links for previous answers that Pvalde2 posted in the above response, the F11 code indicates that the CCU (Central Control Unit) detects a communication error between the CCU and the MCU (Motor Control Unit). This failure can be caused by a wire harness connection problem between those components. It can also be caused by a wire connection failure between the MCU and the drive motor. A problem with the door switch could also cause this problem. I provided technical information about your Whirlpool Duet washer in the image below. The first image provides general information about the control boards and the motor. The second image shows basic access information for the components. Be sure that you
the washer before accessing internal components. The third image shows testing information for the components and provides a wiring diagram. It also has connection locations on the control boards. I recommend that you
unplug the washer
and check the wiring connections between the control boards, drive motor and door lock assembly first. Unplug the connections and plug them securely back in. This will sometimes fix your problem. If not, you can check the resistance through those components using a volt/ohm meter and following the information shown in that third image.
This F11 code is sometimes difficult to diagnose and repair. The most common cause of this failure is a bad CCU control board. That is an expensive component. I recommend that you check for other causes before replacing that CCU.
