Thanks, I remember that post but cannot find it. But I checked hinge with loupes and I see no straightforward way to remove the cover.There was a guy on the Amflow Facebook group who had the door come off. He was advised to use a craft knife to reseat the door hinge pin and spring. He reported it was straightforward to do.
I tried to remove the door on mine using the same method but gave up eventually for fear of breaking or scratching something.
