Gray water read at 40%, even though itís empty

Hello friends,

This is probably a common issue. So my gray water tank is completely empty, but it still reads ~40%, any recommendations for making it reads correctly? Thx!

Btw, my trailer is only 4 months old.

my grey tank sensor says 69%

This is a common problem. You can search YouTube for solutions. The problem seems to be not with the sensor itself, but with dried-up gunk built up on the inside of the tank wall. Bottom line, the inside of the tank needs to be cleaner (easier said than done)

I just had the same problem. Stuck at 69%. But after using it and driving it the reading corrected itself. My guess is as above, there was something on the sensors.
