RV Tank Sensors Always Reading Full
Why black and gray tank sensors get stuck and never read empty even after dumping.
Debris Buildup
Paper and sludge stick to the tank walls and cover the sensors, completing the circuit. This makes the panel read 'Full' even when empty.
Cleaning Solutions
Chemical digesters or a professional hydro-jet cleaning are the best ways to restore sensor function. The 'ice cube' trick is largely a myth.
