Tank sensors not working

[Foxden617]

I have a micro-monitor sensor for my 2005 Pleasureway, and even after we empty the blackwater tank it still shows 2/3 full. Last time after we dumped it showed full. I’m thinking the sensor may be broken - does anyone have experience with this? The other lights on the micro-monitor seem to be accurate.

Ours hasn’t work in years. I use a flashlight and look down into the tank to check the level. If you find the fix for yours please post it. 2005 PW Plateau TS

Do you have a sanitary rinse? Even with a relatively new rig I got inaccurate reads. I installed a rinse nozzle (not the spinning type) and rinse inside of black tank after every trip. This has resolved my reading problems.
