You are missing a digit in the model number. KitchenAid Dishwashers have a number (0-6) after the SS.
The KUDI01FLSS0 installation guide gives the dimensions of the dishwasher opening and the unit itself on various pages. See http://www.kitchenaid.ca/assets/pdfs/literature/Installation%20Instructions%20-%208524480.pdf
. The top vent and the front vent KUDI01FLSS model washers are slightly different. The front vent dishwasher dimensions are 33 7/8" H (with the wheels removed) x 23 7/8" W x 24 7/8" D (including the handle). The top vent model is only 24 1/2" deep. With the wheels in their lowest position, the opening for the dishwasher must be 34 1/2" high (from floor to the bottom of the counter top).
I hope this helps. Other KitchenAid appliance manuals are available here: http://shared.whirlpoolcorp.com/product_literature/search.jsp?siteCd=KAD
