The subject error code relates to water in the leak detector mechanism. To inspect this, the door panel needs to be removed first.
Video instructions indicate removing six screws, pulling the base of the door out and down to accomplish removal.
Did not happen!
I have pulled very hard. The panel is free at the base and sides, but there is something definitely still holding it at the top. Supposedly the remaining screws hold the electronic panel in place. I am not willing to apply any more force for fear of tearing the door off.

Any ideas?
