Another possibility is the shipping bolts were not removed before operation.  From the Owner's Manual:


  To prevent internal damage during transport, the washer is equipped
  with four shipping bolts and plastic retainers.
  
  IMPORTANT:
  
  
  These shipping bolts and retainers MUST NOT be removed until just before moving the washer into its final position.
  These bolts and retainers MUST be removed before operating the washer.
  Failure to remove shipping bolts and retainers may cause severe vibration and noise, which can lead to permanent damage to the washer.
