Winnebago uses non contact tank sensors and they're usually pretty accurate. You have a 42 gallon grey tank and it probably takes a lot longer than 20 seconds to empty, more like 2 or 3 minute's.

The other possibility that was mentioned earlier is some nut left one of the install cutouts in the tank and it is blocking the drain.

I can see the gray tank in my storage closet and it has wired sensors on the plastic sides, so those look like contact sensors to me.
I emptied my tanks again today and I timed them. The gray tank was full to the point of standing water in the kitchen sink. They took longer than my guess. The black tank water and solids rushed out for about 15 seconds and continued slower for about another 5 seconds. The gray tank water rushed out for about 30 seconds and continued slower for about another 5 to 10 seconds.
2 or 3 minutes is way more than it ever took to drain the gray tank, even when it was brand new. I still say the 30 seconds seems about the same as it was before when I drained after 2 days, instead of 1.
