Got the 6200 about a month ago. It has always made this "chattering" noise. Sounds like air being sucked in and chopped up even though no air is being sucked in. The noise is constant and doesn't wax and wane. At first I thought it was the pump vibrating against the magnet holder but I wedged a piece of a mouse pad in there and the noise didn't go away. Any ideas?
