Knowing how much water is left

Hi,

Currently with water I only know it's gone when nothing comes through the taps.

There is a low water indicator but it is alway flashing red. Even after filling up.

There is also a reading on the control panel but it just returns 0. This did return non zero readings for a while after getting the camper. Other functions and readings on the control panel all work fine, it is just the water that doesn't.

Wondering what may be up. Is there a sensor in the tank that may be gone ? Or a manual step that needs to be done after refilling.

Would there be another way or trick for getting an idea of the water level ? The tank underneath is a dark colour so I can't get an idea from looking at it how much is left.

I have a 4” inspection cap on the top of the tank under one of the hab seats which I peek through

It actually seems to be working again for now. I turned the main battery control panel off an hour ago as I could hear the fridge taking a couple of goes to come on and the leisure battery voltage was reading low.

When I turned it on again, the red led indicator stayed off and the reading is now consistently showing 46 (on previous occasions consecutive button pushes showed different readings). I wonder can this also be related to how I park ? I'm using it off grid at the moment and am rarely completely flat.

Either way I'd prefer have something else other than dodgy electronics and like the idea of a pipe plumbed in. Is that a common workaround ? Something that any RV dealer/builder should be able to do ?
