Concerned about this washer.  Was just purchased from and installed by a very reputable dealer.  Read and followed ALL instructions.  First wash, it is terribly loud, and began to be unbalanced.  Was rocking and made knocking sounds.    The instruction booklet is very good, it has good features/options, but if it can't stay balanced even to wash cotton sheets, that is a huge problem.  And too noisy.  Also, for a person who is 5'1" tall, I can barely reach the bottom of the washer.  They should say something about that in the product description.
