Dishwasher vibrates excessively or moves during operation.

Safety first: Ensure the dishwasher is empty before adjusting its position.

• Check level: Place a spirit level on the top edge of the tub. Adjust the front and rear leveling feet until the unit is level side-to-side and front-to-back.
• Secure to cabinet: Ensure the dishwasher is fixed to the countertop or side cabinets using the correct mounting brackets and screws.
• Check for contact points: Make sure the tub or door is not rubbing against cabinetry.

Proper leveling and securing usually resolves vibration issues.
