Safety: Turn off power before adjusting installation hardware.

Level the unit: Use a level on the top of the tub and adjust the front and rear leveling legs until the dishwasher is stable and level.
Secure mounting brackets: Ensure the Samsung mounting brackets are firmly attached to the countertop or side cabinets.
Check floor contact: Confirm all feet are in solid contact with the floor and not on soft or uneven surfaces.
Inspect spray arms: Make sure spray arms are intact and not causing imbalance due to damage.

Dishwasher vibrates excessively or moves during operation.
