Have you descaled the machine lately? If you have hard water like I do, you would be surprised at the amount of gunk built up in there. Can you get a consistent water delivery? In other words if you press medium, do you get the same amount all the time? Have you tried the Keurig.com website? They have some good info. Also, a lot of good info on You Tube about the Keurig.
