I know this an old post, but my water and waste tanks were both reading full even when they were not. I found the tanks and senders, looked up the manufacturer's web site and found instructions for recalibrating the senders. Fortunately, it worked for me.
I have a 2005 Tiara 3800. The tank level system is made by Xintex, model LLM-2. The hard part was removing the senders, especially the one on the waste tank. Once removed (and cleaned up) the calibration involved applying 12-volts to the red and black wires with the white and green wires connected for 30 seconds while the sender sees empty condition (~1.5 in. Of water at the bottom of the tube). The full condition is calibrated by disconnecting the white and green wires for 30 seconds while the tube sees a full condition. Once calibrated the 12-volt supply is disconnected and the senders can be reinstalled. It worked for me!
