Here are some more unusual possibilities to consider based on the thump you heard just before the problem appeared -
The thump you described makes me wonder if you didn't blow something on the fresh water side like a valve or check valve. Have you turned the water back on? If so then I assume the problem did not re-appear and that would not be the problem.
Is it possible that black water flush system was somehow feeding back into the black tank? The thump could have been the tank expanding just before your DW started seeing water. If that is indeed the problem then you may also have a clogged vent pipe on the black tank. A clogged vent pipe might explain why the toilet would not flush. Did you notice any smells beforehand? The vent pipe may have somehow become clogged when you flushed the tank previously.
