If it’s similar to our ‘06 Monty it’s behind a carpeted wall panel in the large main storage bay. Facing the bay from the curbside open bay door, you may find the panel along the wall to your left, near the electrical and coax outlets. It’s meant to blend in so you need to look closely.
Just for additional related information that many new owners aren’t aware of on coaches like ours, there is a handleless bay just forward of the curbside rear wheels, and it adjoins the large bay that the pump and its acutrements are accessed from, as I just noted. The pump and stuff is housed in a plastic box that extends into that handleless bay that also contains your waste tanks, some Aladdin modules and solar controller, and on the street side has your water bay. The handleless door has two draw latches along its bottom edge. You may have to get on hands and knees to see how they work.
So though the pump is actually in that handleless “wet bay”, where it has exposure to a ceiling-mounted heat exchanger for freeze protection, you can only get to the pump by pulling off the panel in the big storage bay. There may also be an in-line fuse near the pump, but there is definitely a 10amp one for the pump at position 10 (far right) of the righthand Multiplex module (block B in my photo below) in the electric cabinet over your toilet.
Now if no one has serviced the pump recently, you might check that it’s inline screen filter isn’t clogged. If unused for a long period and without annual system sterilization, algae can grow on the screen. Also, these pumps don’t last forever so it just may have reached its life expectancy.
