Every time the black tank reaches 50%, the display immediately jumps to 100%, the red light comes on at the flush panel and I can no longer flush the toilet. Once I dump, the display eventually shows 0% and everything returns to normal.
I tried filling the black tank 4 times up to the 50% mark, and each time it jumped to 100%
My Newmar customer service rep told me that the sensors work on pressure, but looking at the sensors, I don't see how. Ultrasound or RF makes more sense.
Newmar is sending a mobile tech to take a look. Hopefully he can fix it.
