Hi
You might need a brew head cleaning. It can get pluged with coffee residue and oils. But you could also have a bent injector valve or gate valve. But I would try this first.
Remove the brew unit. Holding the handle, the top left side is the brew head. There is an outlet pipe that exits the front side towards the door (looks like a long "L" pipe). 2screws hold it to the top. Remove the 2 screws while holding the manifold ("L" pipe assembly). Once they are removed, lift the l assembly off (be careful, there is an O-ring, spring and at the end a black rubber disk.
Now remove the brew screen, by holding the screen with your finger and twisting the thumbscrew (remember, thumbscrew), DON’T use the key to install the screen, use your fingers.
Once the screen is out look at where the screen was. There are 2 holes. A big one in the center and a small one to the side.
With the brew unit upside down over the towel, insert a paperclip into the small hole and force anything out the other side. I have gotten worms almost a 1" long from this passage. The paper clip has to go from this side to prevent damage to the seat on the other side.
Clean then reassemble. Brew unit on towel right side up. Drop the crystal ball in first. Then the spring small end first on the crystal ball.
Now the O-ring over the spring, then place the manifold on top of that with the pipe towards the machine. Insert your screws (I turn them backwards a little with a little downward pressure until they feel like they drop into the threads. They should turn down easily, if not back them up a little more ( we are trying to find the old threads) and tighten. Install screen, and tighten with your fingers. The screen just needs to be flush with the bottom of the brew head. That should do it.

Hi its not the boiler. Its you brew head. Here is how to clean it. Remove the brew unit. Holding the handle, the top left side is the brew head.

Hi If your talking about the tube on the brew unit, you are probably missing the spring or if you have the spring its upside down. Again if this is what you are taking about is the check ball at the bottom of the spring(ball in first, small end of the spring on the ball, O-ring, then the manifold)These things are important for creama.
Hi Are your coffee grinds wet? If they are you have a clogged brew head. Remove the filter screen. Then remove the 2 screws that hold the outlet manifold to the brew head. There are 3 things under the manifold. O-ring, tapered spring and a crystal ball. Don't lose any of these items. Now to clean the brew head turn the brew unit over to where you can see where the brew screen was. You will see 2 holes, 1 large and 1 small. Take a paper clip and straighten it. Turn the brew unit upside down and insert the paperclip into the small hole. Push the paper clip through and remove the plug. I have seen them over 1/2" long. Reassemble the brew unit crystal ball first, small end of the spring on top of the crystal ball, place the o-ring over the spring and place the manifold on top making sure the outlet pipe is to the outside of the brew unit. Put the 2 screws back and your ready to go. Run a detergent for espresso machines like Cafiza through the brew unit every once in a while to keep it clean. It doesn't take a lot of detergent and use the pre-grind setting and a large cup selection but don't put any coffee in.
Hi, We had a similar problem and it turns out the beans we were using were too oily and clogging up the works. We solved it by using a slightly more coarse grind (and brewing a stronger cup), and by buying only the best beans (oily beans don't make coffee stronger, just means they aren't good beans and by roasting longer can make the coffee taste stronger). Try Barefoot Coffee Roasters (I don't work for them, just love their coffee). We also use the cleaning tablet more often than prompted, and clean the inside of the flap when we dump the grinds. Good luck. Great coffee, but finicky machine!
I found a machine in my dentist's office with this exact same problem. I'm not familiar with the model, so I downloaded a manual for the closest model I could find online (the Sirius), and it offered no help -- but in 8 languages!
I ended up just pulling the drip tray, pulling the box where the grounds end up, and re-inserting the assembly (all while the machine was on.) When I buttoned it up again, it worked.
Hope this helps (although I can see how it might not...)
