I am using panache beans with a new Kitchen Aid burr grinder

You might want to do a search on your grinder. My recollection is
that people modify the Kitchen Aid in order to get a fine enough grind
for espresso. You do have a generally well regarded espresso machine.
In the long run, you may be well served by a more capable grinder.

It sounds like your grind is too coarse. I am not familiar with the
Kitchen Aid grinders, but my experience has been that something that has
been designed for espresso grind is pretty important. I started with a
Solis Maestro and just moved up to a Faema MNP (it's kind of overkill
for home use, but the price was right). As most people will tell you,
the grinder matters most of all in good espresso.

Actually reduicing the brew pressure won't do anything for you, since
the flow from through a gioven puck is roughly the same from 6 to 14
bar.

Learn something about espresso, buy fresh coffee, buy a grinder.

What kind of grinder do you have? What kind of coffee are you using?

It's unlikely to be a pressure problem. You can reduce pressure by turning
the nut on the barrel of the expansion valve (located on side of group head
inside the housing - hose leads to drip tray) but that's unlikely to be your
problem.
