Water tank sensors not working

[Debannq]

My fresh and black water tank sensors are not working properly. I just emptied all the tanks yesterday and they still read 1/2 full for black and 1/3 full for fresh.
What do I do?

moving this to the Truck Camper subforum for better visibility. Can anyone help?

There are videos on youtube about the issues that occur with theae sensors and how to fix them. Search “RV tank sensor problems” or something like that.

On a previously owned Roadtrek I poured a bag of store-bought ice down marine toilet into blackwater tank that was about half full of plain water and repeatedly drove over a certain diagonal drainage dip in road known for giving one whiplash if you drove over it too fast. That knocked the crud off and fixed it.
