Two things;
First, pull the Two screws on the triangular shaped cover at the drivers side rear of the unit, it's carpeted, and under there is the backside of the water fill. My vent hose was kinked shut, I imagine all are. They leave slack when connecting both hoses, vent and fill, then push them in and secure the mounting flange, this kinks the hose. You have to cut the hose, cut a 2" or so section, then re-join with a barbed fitting and 2 small hose clamps. You need that working vent.
Second, secure the cords with wire ties on the slide outs at the outside ends, the black rubber coated wire will get caught around the protruding bolt and cause strain and possibly pull it in two.
Easy quick fixes that will pay off in the long run.
