Couldn't find my best sock after a camping trip.  I KNEW I put 2 in washer.  Finally thought it must have fallen over the rim of the washer basket when I was transferring clothes to dryer. Tonight before my very eyes as I was transferring clothes up to dryer I saw a pair of underwear and a small cleaning cloth slip over that top rim and down-LOST FOREVER! They just rolled over the rim that is just below the lid and top of washer.  This is a NEW unit replacing the 15 yr old one.  We were told they won't be making this stack model very much longer so invested now & donated the old good one.  Now I'm learning I must use many lingerie bags each load for all my socks & smaller items. I'm going to try and add a warranty so I can have a service man get my clothes back to me.  Otherwise, I do love the machine, uses less water, cleans beautifully, dryer has great sensors.  I just don't like loosing my clothes!
