I hate to say this and there are some other threads around here somewhere on this problem, but some people have reported in the past on such blockage problems on brand-new units.
After jumping through all the hoops it sometimes came to the point where the tank had to be completely disconnected and dropped to find the problem. I remember one poster who said that when the hole for the toilet was drilled out that the "disc" of plywood had dropped into the tank. It was probably close to quitting time and the worker who made that mistake conveniently forgot to fish the piece out of the tank. Well, that piece of wood blocked the drain and the whole tank wound up full of sludge and it was a nightmare of a mess.
I REALLY hope that isn't your problem, but on a brand new unit you should not have enough of a build-up to cause an almost complete blockage. The only way that might happen in normal usage is if you kept the valve open all the time. That's a no-no...you need to have a good amount of liquid in the tank at all times until it is drained. (And personally, I always add several gallons of water afterwards when the TT is not in use.)
