My DE6744 dishwasher is leaking from the blue plastic component found on the left behind the side panel. The water overflows during the fill stage. There is a section halfway up on the left of this unit which appears to be a brown liquid? is this supposed to be there or is it just water that is stuck. I believe the unit to be blocked & before I strip it down I just want to make sure I don't remove anything that should be there. What does this unit & How does it work. see images on this link..http://picasaweb.google.co.uk/greggnzoe/20090711222445?authkey=Gv1sRgCISk5OPu1sCHVw#5357320535231231906
