How do I level the dishwasher properly?

To check leveling, remove the lower rack and pour 169 oz (5 L) of water into the bottom of the tub—the water level should be near the center of both tub lower indentations at the front. Adjust the front leveling feet using a flat-blade screwdriver (turn clockwise to raise, counterclockwise to lower) and the rear leveling foot using a Phillips screwdriver at the center screw at the base. Proper leveling is critical to prevent leakage, door closure problems, and noise. (Page 21-22)
