Bryan C Willard , MO March 26, 2016 F 11 and door lock codes Replaced the door lock a few weeks ago. Continued to get f-11 code multiple times during a load. Took approximately 15 minutes to install the control unit. Not one problem after 6-7 loads washed. Wish I had done this 6 months ago. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
