Fresh Water Monitor
2015 Forester 2801QS. Fresh water monitor reads full or empty. Nothing in between. I cut a hole in black plastic shroud to see the tank. It is half full and monitor panel reads empty. Other tanks seem to read correctly. I kept hitting the button as the tank was filling. At half full still read empty. ?Somewhere near full, the 1/3, 2/3, and full light blinked briefly. Then the 1/3 and 2/3 lights came on solid. The full light blinked for only a second or two more and then remained on solid. Anyone else have this situation? Any solutions other than changing the entire system?
