Product review (5 stars): Better than original
I really only needed the motor but the price on this part was too hard to pass up.  This assembly includes all parts shown in the picture and was in brand new condition.  I went ahead and replaced the entire assembly and it fit perfectly in my Whirlpool Duet and was very easy to install.  The small hose shown in the picture is a drain hose so that you can drain the water out before you empty the filter.  It is a very handy improvement over the original design.
