I will take a shot at this question, only because I had a similar problem this past spring. You probably have everything hooked up correctly, the pump, the shaft key, and everything else the way it should be. If the unit sat for a while, or a long period of time ,it may have built up some rust , at the nozzle end. I will assume that your pump comes on and no water comes out of nozzle. If this is so remove nozzle and look through the small hole in nozzle. If you don't see light this is most likely your problem. Take a small piece of wire, or a pin and push it through. I had a nozzle clog on me this way. I didn't think this could happen till I started to diagnose down the line. Please get back to me with your results. GOOD LUCK FREIND.
Gartermor Sep 30, 2014 Water comes out of nozzle with pressure for a quick second then no pressure, just water. This is a brand new pump so was curious if I installed it wrong. Wondering before taking it apart again.
I am curious as to how you made out with your pump problem.I was hoping you wouldn't have to take your unit apart again. There is another possible answer to your problem which is that your pump pistons have become stuck inside the pump. But at least it is known that the water flows through your unit the way it should. Please get back to me and let me know what is happening.
This is a brand new pump so the pistons and entire pump should be fine. Also, a brand new trigger nozzle. That is why I was asking about not having the shaft key in properly. It seems like that would be the only thing I screw up. Everything else is new. Thank you for getting back to me. I'm just at a loss so I guess I start over from the beginning.

The mechanical engineer in me just had to solve the problem. I unscrewed and removed the bottom plastic cover (3 screws) where the power card goes into the machine and found the problem. The water from the reservoir feeds into a white plastic priming pump. This priming pump is assembled in two halves and one half has four plastic clips that hold the pump together. In between the two halves is a rubber o-ring. Well, one of the clips was not secured and I could see part of the o-ring protruding. This is an obvious source of leakage. Either the pump was not properly assembled or it snapped out of place during shipping.
I unscrew the two screws that hold the priming pump in place, leaving the hoses attached, and carefully pulled the two pieces apart. Note how the magnetic impeller is installed and reassemble the same way. Use a small amount of vegetable oil to lubricate the o-ring and reinstall in the same place. Reassemble the to two halves, making sure the o-ring doesn't protrude, then snap the two halve together tightly. Screw the primer pump back into place then screw the bottom plastic cover back into place.
After this fix the machine no longer leaked and it brewed a nice espresso. Everyhing seams to work find now.
