Cannot properly align Saeco Italia Coffee...

Question

The drive hub on my "new-to-me" Italia does not properly mesh with the dispenser axle splines. I downloaded the manual and there is no mention of this problem.I observed the power-on cycle with door open ( all interlocks pinned shut and dispenser, tray, grounds cup removed) and the drive hub always stops in the same orientation but the drive hub teeth do not mesh with the dispenser axle splines and the dispenser will not re-insert. The drive hub consistently stops with its two large "teeth" positioned between 12:00 to 6:00. Aligning the dispenser so that the two arrows align at 'N' puts the corresponding dispenser splines at 8:00 to 2:00.
