Chances are the black tank goes to one dump valve...there could be a clog in the line to that...or the vent to the roof could be clogged...
1. Call HR support with your VIN # and Coach #....they should be able to look up coach and tell you if there is a 2nd dump valve or there is one master black tank...if it is one drain, then I bet you may have to get on roof and make sure vent is clear...Once all is clear, you can test the black tank for that toilet by holding button for six seconds, this will over ride the red and if tank flushes, then you are down to the sensor or a good tank clean.
