There are always some very interesting problems on this forum. I can't wait to find out what is going on with your system.
I have a manual on the toilet, but it is too large to attach. If you want a copy PM me (also there may be a copy in the Members tech section). However nothing in the troubleshooting section deals with your situation.
I would double check the shutoff valves (that nothing is closed or partially closed for the bathroom) located in the wet bay - while waiting for someone to come back with the solution to your problem.
Good luck.
