So, the code B11A002 means one of the closing switches in not working correctly or is broken, I would inspect the switch: Top left, Top Front or the Top lock switch, use a flashlight to see if you can see which one is broken or has come loose and is not contacting the top when it closes. Here is the location of the switch so you can check it out in the images below. Let us know what happens and please upload pictures or videos of the problem.
