Washer is eating and tearing my clothes too!

I've had a Duet Sport Washer since May 2007.  I had a major problem with it mechanically, and in October 2010, the extended warranty company sent me a check for 75% of cost of a new washer.  Because I have the Duet Sport dryer stacked on top, I was forced to buy the Duet Washer again.  I preferred not to.  In January of this year (2013), a valve in the machine needed replacing.  In February, the machine started to leak water from the front.  The serviceman found a hole in the rubber door seal.   He replaced the door seal with a different type that leaves a good 1/2 opening between the tub and the inside of the machine.  Yes, you guessed it.  Just like too many other Whirlpool customers, my machine ate a large sock that a repairman found in the pump last week.  Today, it almost swallowed a sock but I caught it.  Also today, it tore holes in a new T-shirt of my husband's and in a large gym sock.  Strange plastic bits were stuck to the sock, as well.  I also found plastic bits in the bed of the seal last week. At first, I thought it was the different configuration of the rubber door seal, because with the first rubber seal design I had no problems I was aware of. However, I suddenly remembered not finding the mate to 3 pairs of socks, a few months ago.  Obviously they are floating in the Potomac.   So, it isn't the door seal.  It is very obviously a serious design flaw that Whirlpool has chosen to ignore.  Here I go again calling the extended service plan company.  I'm sure they'll have some ridiculous excuse for it, when they come to look at the washer.  In the meanwhile, I am afraid, like so many  other writers, on this complaint site,  to use my washing machine for anything.  What are we supposed to do?
