Maybe your black tank/line is blocked.
I am new at all this but the hose you connect to the black water tank for clean out, once I opened that black tank and turned on the hose nothing came out. I turned off the water, opened what was labeled grey tanks and out came the blue water and it started to drain.
Just have to swap the labels and glad the black tank was only 1/4 full, could of ended really bad.
Crossroads needs a better QC check list.
