When the water line goes through the floor it hits a valve on the refer. It goes through the filter then splits for the ice maker and the door spigot. I would suspect the control board, it was problematic in the Amana. WRV had a modified board, a resistor was replaced and that corrected the issue. The Onan inverter was a modified sine wave and burned up the resistor in the control panel located behind the water/ice dispenser.
There are 4 torx bolts through the floor that hold the refer in place. Those bolts are accessed from the holding tank bay and the storage bay. There are also holes in the floor that the rollers drop into, but you can roll the refer right out.
I do not use the water in the refer, I buy ice and use the door to dispense it, but I do not use the water. I do not want to hassle with the water left in the refer since I might not use the coach for 3 or 4 weeks at a time.
