Pull the dishwasher out from under the cabinet so that the front of the top of the appliance is accessible.
Insert the tabs on the bottom of the L-shaped mounting brackets into the notches on the front left and right of the top of the dishwasher. Ensure that the brackets face away from the center of the dishwasher.
Bend the perforated ends of the brackets forward to form a 90-degree angle on the bracket.
Rotate the brackets down, toward the front of the appliance, ensuring that the tabs remain inserted into the notches on the top of the dishwasher.
Move the dishwasher into position.
Drive the included screws through the holes in the brackets and into the cabinet to secure the dishwasher.
