We had an electric Aria toilet and had nothing but problems and it was a very, very expensive toilet. Finally the electrical components failed and we replaced it with an ARia non electric (still having problems with that too and it's also a very expensive toilet)
There should be a way to manually flush the toilet until you can get it worked out. Do you have a manual? On ours, we had to reach around behind it to manually flush. Not fun, but do-able.
