Can't prime new machine

Experienced the "needs prime" message on my Starbucks Digital Barista, a 2004 model so now 7 years old. Hot water came out of the wand normally when I turned its control knob but "needs prime" message remained on the display. I ended up taking out the beans and removing the water reservoir, then laid the unit on its side and turned it upside down and gave it several slaps. I didn't really expect this to solve the problem but it did! Am at this moment enjoying my first post-problem espresso and it is fine.

Yep, my new machine had the same problem, I tried everything for 4 hours. Finally took the back off the machine. disconnected the water tube, filled the water tube with water, hooked up a bicycle pump to the tube, (with an adapter for standard inflatable pool toys) put about 25PSI of pressure behind the water in the tube it to force water through it. re-assembled the unit and it primed right away. I have heard horrible stories about sending these back, waiting months, etc, so I was ready to try anything. I then went to square trade and purchased a 2 year warranty for $50. Even though I hate warranties, I think maybe its a deal based on what I read about this unit.

Brand new machine you put water in the container prime it with turkey blast open the valve on the side off machine and it still does not work tank good for warranty cheers
