Any tips on removal of the old unit, installing, or things I need to buy....
Let's see, its been some years since I got my first dish washer. It occurred on August 4, 2001. My wife celebrates that date every year as I always seem to forget. When I do remember it's typically called, "Black Tuesday" or what ever day of the week it falls upon.
Most recently I was thinking about getting a new, modern, and trendy dish washer. Perhaps one built around the year I graduated high school, maybe a 1989 model.
As for tips of removal, it might be easiest just to find a new one and move her on in before you kick the old one to the curb. You could call a couple single buddies that may be willing to take the old one off your hands or just send her to the street corner. After a day or so someone will come along and pick up the old one. Chances are you will never see her again.
As for installation tips, They are built for one thing so use it and abuse it. They make new ones everyday.
