Dishwasher vibrates excessively or moves within the cabinet during operation.

Safety first: Turn off power before adjusting the appliance position.

• Level the unit: Use a spirit level on the top edge of the door opening. Adjust the front and rear leveling feet until the dishwasher is level side-to-side and front-to-back.
• Secure to cabinet: Check that the mounting brackets at the top or sides are firmly screwed into the countertop or cabinet.
• Balance the load: Avoid placing all heavy items on one side of the lower rack.

Proper leveling and securing usually resolve vibration. If not, a technician can check for internal suspension or tub support issues.
