Adjust as needed until the dishwasher is completely leveled.
Adjust the front and rear leveling feet until they are all in firm contact with the floor. Failure to level the dishwasher may prevent the door from closing properly and the dishwasher will not turn on.
Use a flat-blade screwdriver to turn the front leveling feet and adjust the front of the tub.
Turn the front leveling feet clockwise to raise the front of the tub and counterclockwise to lower it.

The adjustments work identically for both front leveling feet.
When a flat-blade screwdriver is unavailable, use a 1/4" square drive wrench a or 3/8" square drive wrench b with 1/2" socket c to turn the front leveling feet and adjust the front of the tub.

Use a Phillips screwdriver to adjust the rear leveling foot and the rear of the tub using the center screw at the base of the appliance in the front.
Turn the center screw clockwise to raise the rear of the tub and counterclockwise to lower it.

To avoid damaging the screw, do not use an electric screwdriver.
