2014 Vista 35f Half bath black tank will not dump

We stopped at a local campground to dump and hubby went to dump the half bath and when pushing the button nothing happens but we hearing the macerator grinding noise, but nothing comes out the sewer. We hooked up the water hose to flush the tank and you can hear the water going into the tank but again, nothing happens when he tries to dump. Now the tank level says it is full (of water I'm guessing as it was third full prior). The full bath dumps fine, grey water dumps fine. We left things alone and came on home to settle back in. Just for information, he dumped the tank fine last Thursday before leaving Friday morning. What happened and what should we do? Thanks in advance!

I am sure you already know, but I will say it anyway. There are two valves , one in with the macerater. And one in with the main valves. The in the back has the valve above and behind the panel with the power button. Both need to be opened to drain the tank. And don't forget to close valves when done. Hope this helps.

Yes we know there are 2 valves; have done this enough by now to remember. I believe that there is a clog. Maybe my question wasn't clear enough, how do we remove the clog? The tank is now full of water and added more TST chemical. It will sit for a day or 2 and see if this loosens up the mess.
