Step 1

Slide the dishwasher into the designated opening. Adjust the dishwasher, by leveling and plumbing it, to the desired position.

Step 2

Equip an electric drill with a masonry bit featuring the same diameter as the screw that will be used to secure the dishwasher. Use a regular drill, rather than a hammer drill, to prevent cracks and chips in the granite countertop.

Step 3

Hold the blue masonry screw up to the drill bit. The head of the screw should be located at the tip of the drill bit. Wrap tape around the drill bit so you know how deep you need to drill. This will prevent you from drilling too far or not enough into the granite.

Step 4

Slide the tip of the drill bit through the designated holes located at the top of the dishwasher. The bracket will prevent the drill bit from moving while you drill the holes.

Step 5

Hold the drill at a 90-degree angle and make a hole in the granite countertop. Start the drill slowly to allow the bit to make a rut so that it doesn't slip around.

Step 6

Insert the blue masonry screws into the drilled holes and tighten them with the appropriate size bit; refer to the screw packaging to determine the correct size to use.
