Have you tried flushing water thru steam wand?
Yep; works fine.
So, you can pump water out of the steam wand but not through the group head? That would either be a grouphead blockage or a 3-way, but you've already checked the 3-way.
I'd use bottled water. Easier, and better coffee.
Grouphead blockage .. sounds fun .. how do I unblock?
