Place a level on top of the Duet to determine which legs must be raised or lowered. Test both side to side and front to back.
Pull the Duet slightly away from the wall, then lift the front and prop it up using a wood block.
Use a 17 mm open-ended adjustable wrench to loosen the nuts at the top of the leveling legs, which secure the legs into position.
Turn the leveling legs clockwise to lower and counterclockwise to raise.
Tighten the nuts at the top of the leveling legs to secure the legs into position and prevent them from moving when the appliance is in use.
Lower the washer, then recheck the level of the Duet.
Continue adjusting the leveling legs until the appliance is level both front to back and side to side.
