My fresh water gauge always reads very low. Fortunately I can see the tank and see the water level in it. I was told that if I added a little salt to the water, the gauge would read correctly. I never tried it.
The gauge checks for continuity between contacts in the tank. Good clean water has too high a resistance so the gauge reads low.
I'll bet the gauge reads wrong.
