I had this problem too and thought it was fatal so I bought a new machine. the new machine came with a maintenance accessory (my old one did not!) The problem was simply a clogged needle. After clearing the needle with the maintenance item, the old unit worked as new. There was no hint of this accessory anywhere so was unaware of the clogging potential easily solved with the "maintenance accessory" that did not come with my original machine Shame on Keurig. Now I have two coffee makers!
