Just unpacked my machine and when I fire it up the boiler heats to 2bar and then the pressure release goes

Ideas?

If new, call the reseller - could be a faulty P'stat, incorrectly wired P'stat, blocked passage, etc.

Is there an easy way to "unstick" the pstat?

I trust your word Dan. If it's problematic I will go through the exchange process. I got it straight from royal falcon.

I was just anxious to use the new machine.

Just as an update: Grimac Royal Falcon had one of their espresso techs look at the machine. It turns out that a calcium deposit was blocking the diaphragm in the pipe that leads from the boiler to the pstat. The blockage was preventing steam from getting to the pstat. The tech took off the pstat and cleared the line with a paper clip. The block in the line came from testing in the Italian factory.

After all of that I am up and running. Excited to get home tonight and post a pic in the home espresso setup thread!

Uhh... really? That's what they told you?! It is difficult to believe that the test done at the factory, which would be short in duration even under the most stringent of standards, could do that. My first response to that if they said it to me would be, "B... S...!" A $1700 machine, new, with scaling problems? It would make me question whether it was really a new machine or the procedures at the factory, or how long it sat in a box with really hard water in it before you got it.

I am not certain it was calcium. Just a blockage in the line. The boiler was tested in Italy in April 2011.

I do not think I can or will return the machine now as it is operating well but is there anything that I should watch for over the next few months that might indicate a prior water hardness problem?
