I press the carbonating button on my drink maker and nothing happens.

Usually this is a sign that there may be two sealer washers in the carbonating gasket head. The sealer washer is a small, black, O-shaped ring about ½" in diameter. To try and correct this problem, first remove the carbonator cover in back of the machine. Unscrew the carbonator from the fitting and lift the machine so you can see inside the gasket head. Using tweezers or a small screwdriver, attempt to remove the black rubber washer from the head. If there is a second one underneath it, you've just solved your problem! If not, please replace the washer in its original position and call Customer Support.
