Keurig Elite B40 Won't Close
This morning, my Keurig Elite B40 wouldn't brew. I put in a K-cup, and hit the brew button, but no water came out. So, I proceeded to follow some tips I found online for unclogging the needles and checking the tubes. I had to undo the two screws underneath the top housing, so that I could pull it up and check the tubes. I saw nothing wrong with the tubes, so I replaced the screws without doing anything inside the housing.
Now, the top won't close. When I look inside to see what's blocking it, I see a metal tongue back behind the K-cup holder and a bar that looks like it's supposed to slide over the tongue and into a groove. However, the tongue is completely rigid and locked in place, such that the bar would have no hope of sliding back into the groove. I'm assuming the tongue is supposed to have a little give so that the bar can slide over it into the the groove, but since it's rigid, it's impossible to force the handle closed against that pressure.
I didn't mess with anything in this part of the machine - my fingers wouldn't even fit back there. Did I inadvertently mess something up when I slid the top of the housing off to look at the tubes? Help!
I added pictures of the metal tongue and the bar I'm talking about, as well as a photo showing how the Keurig won't close. The photo shows as far down as the handle will go in its current state.
