Did it work before this?
Sometimes hard water can build up and cause blockages.
Try mixing hot water and white vinegar (50/50 mix) and try running it through the machine. If this works, run it through a few more times than run cold water through a couple times to get rid of the vinegar.
Good Luck.

I had this same problem water going into the grounds disposal chamber, plus all green and red lights flashing. Was told if I could clear the lights to clean the screen and run a tablet cleaning. I was able to clear the lights tried to run the cleaning but it failed again. I have had my machine for over 4 years so instead of sending it back I decided to take it apart. The problem I found is an O-Ring that runs inside of the compression pump chamber failed, if I can find an O-ring that is the same size I believe it will be as good as new.

I have a Capresso fo 7 years now, had few problems, but always solve them.
If youe machine does all the functions properly, but doesn't give you coffee, you should check if everytnhig goes into the grounds tray. If that's the case you may only have a broken "O ring" inside the pressing element. It makes the coffe, but throws it away instead of filling the cup. I had that problem, and it was the "O ring".
If the grounds dunped on the tray are dry, you're looosing the water in the back, probably on the relief valve.
Hope this helps!
