I have the 2019 Precept 31UL with the Whirlpool residential fridge, and the water valve for the icemaker/water line is below the fridge behind a wooden panel with spaces in it, like a vent panel. The water/ice maker was not working, and when I found the valve under the fridge, it was turned off. When I turned it on, the small white hose that goes to the ice maker shot out of the brass nozzle, so that was why it was turned off. I did not try to fix it, because we never drink the water or make ice from the park supply or the water tank. I did open the valve on the blue pex line when I winterized the rv to make sure pink antifreeze was in the line. I know I have a different model, but this may help.
