The sensors get paper and stuff on 'em. Then they don't read right. Then it washes off. Then it does.
I usually try and keep gray fuller than black.........not hard. Then, when I dump, all that gray water flushes the sewer hose after the black has dumped.
If/when we get a washer/dryer, I'll have to leave it open much of the time.
