Product review (4 stars): Part is fine, watch out for the installation
I installed this into a Kitchen Aid model KUDS03FTSS.  I consider myself to be fairly handy when it comes to repairs and I'd give this about a 6 on scale of 1-10.  It comes with no instructions but I don't blame the manufacturer for that.  It's a part that can be used in multiple models and what you need to do depends on the model.  The dishwasher door needs to be taken apart to get to the spot where the swap has to take place.  A You Tube video was helpful for that but since the model in the video wasn't the model that I had, some improvising was necessary.  It did give me the basics and that's all I needed.  In my case, the screws that needed to be removed to get to the inside of the door had heads shaped like 6 point stars.  I happened to have a screw driver to handle that but I would guess that most people would not.  Once you get the door apart the removal and installation of the soap dispenser is fairly simple.  The toughest part for me was getting the door back together.  A second set of hands would have made it much simpler but I specifically didn't do this with my wife around because she would have just complained that I should have called an appliance repair person.  In the end, the door got back together, and everything works fine.  The entire installation took me a little under an hour.
