Product review (1 stars): DO NOT BUY!
On our third replacement in less than 6 months.  We will not be bringing home a Whirlpool this time.  Thank God we bought it at Costco because they have THE BEST customer service and return policy.  Vibrates so bad that it walks itself out of place and sounds like it's coming apart.  First did not vibrate but it kept locking up with an F1 error code (drain problem), which I have read is because of a faulty circuit board.  This machine is also supposed to have a smart balancing system, so I would guess that it is controlled by the circuit board as well.  Sounds like they're using cheap, made in China circuit boards to me.  Whatever the root cause of all these problems, THESE WHIRLPOOL WASHERS ARE ABSOLUTE GARBAGE!
