Always an issue, guessing it is on a tiled floor? or up against a tiled wall?
I put some thin foam / Bubble wrap underneath and behind mine to dampen the vibrations. It also helps if you box the unit in and use foam to quieten the noise (on top and around the unit). Depending upon how long you have had it, it may also need a clean out or possibly even the motor bearings are getting a bit worn, creating some noise with the excess movement.
