Hello
E91 is a UI- Main board error. Did you replace them both at the same time? We have found by replacing one at a time does not work. By replacing them both at the same time they sink with each other. I have provided the diagnostic and service manuals. I would run it through a field service mode in the mini manual link below. This will tell you if there are any other stored error codes.
