Attaching a dishwasher to a granite countertop

What? Typically the counter height allows for the dishwasher to just slide in underneath. No need to "attach" anything. What is your set up? Have a photo to post?

Plywood and Adhesive

Slide the dishwasher out a few inches. If you have extra length on the wires and pipes, pull the dishwasher out as far as possible. Apply a layer of clear silicone adhesive to one side of two pieces of 3/4-by-4-by-4-inch plywood. Stick them to the underside of the stone top, centered over the marks you made. If you have room, place clamps on them. Pad the jaw of the clamp so you don't scratch the stone top. If you don't have room for clamps, wedge some books or anything you have to add pressure to the bottom of the plywood blocks. Allow the glue to cure overnight.

Attach

Remove the clamps or wedges from the top. Slide the dishwasher back into place. Check the distance between the clips and the plywood blocks. If the clips are within 1/2-inch, bend them up to fit flush against the bottom of the blocks. If the distance is more than that, pull the dishwasher back out and turn the leveling feet to raise the dishwasher until the clips are within a 1/4-inch or even touching the blocks. Make sure to turn all of the feet evenly so that the dishwasher is level. When you're satisfied with the height, slide the dishwasher under the top and position it where you want it. Bend the clips if needed to place the flat top of the clip against the underside of the blocks. Insert 1/2-inch screws in the holes and drive them into the plywood block to secure the dishwasher to the stone top. Replace the faceplate or filler.

Gk has the right idea but I would use a two part epoxy to adhere the plywood. Silicone can break away.
