Product review (3 stars): Replaced my original with this unit. The only problem ...
Replaced my original with this unit.  The only problem is that the internal stainless door has protruding tabs which lock the new dispenser in place by pushing.  The new unit rubber may be slightly thicker because it will not slide in all the way to lock into place.  Soap the rubber gasket to aid installation, but still will not move in far enough.  I had to use and air grinder to take about 1/16 in. off each tab to make fit.  Don't bother to try and file as this is stainless and it will not work.  It could be that my dishwasher is some 10 years old and tolerances change.  Yours may fit, but mine did not.  Just be aware you may have to modify your dishwasher.
