Okkkkaaayyy!.. So I called the store, after realizing / forgetting, that we bought the display model, that someone had "taken" the piece that fits into this area ( the dispensing button! ).
It had a 1 year mfg warranty..... but does not cover floor models!.
So I'll need to mfg one myself.... Jimmy rig.   But o how silly of me not to think that B4.  Watch out for all parts being there when you buy the floor models.
