Incanto Sirius - grinds but cannot hear coffee getting ground

My Saeco Incanto Sirius was working perfectly until last month. Now, I can make pre-ground coffee, but when using the grinder, it does not make coffee. It makes noise as if the grinder is grinding the coffee but I cannot really hear the coffee getting ground. I don't think the ground coffee is getting into the brew unit. I get water out instead of coffee. Very frustrating. Could there by a jam in the mechanism that pushes out the ground coffee into the brew unit. The unit is under warranty, but I have to mail it to Ohio and pay shipping myself. WTF!
