I am willing to bet that drawer can't close completely, from something like slug/detergent build up, preventing it from closing tightly and not allowing good contact for operation.....had several Fridgemores, one wouldn't work with the dispenser open, yet another one would.....just odd changes in design....
thus also, not closing tightly.....as water from the top shower is flowing around and out the front.....I had come across an LG doing this, that drawer had to be pushing in there snug, otherwise water ran down the front.....
the dirty streaks alone are shown from the drawer area, running down behind the door while closed, appearing to be a seal/boot issue.....chances are, they seen the water on the floor, not staying around long enough to figure where exactly the water was coming from....
