Dishwasher vibrates excessively or moves during operation, especially during drain or wash phases.

Safety first: Turn off and unplug the dishwasher before adjusting its position.

• Level the appliance: Use a spirit level on the top edge of the door. Adjust the front and rear feet until the dishwasher is level side-to-side and front-to-back.
• Secure to cabinet: Ensure the mounting brackets at the top or sides are screwed firmly into the countertop or cabinet walls.
• Balance the load: Distribute heavy items evenly across both sides of the racks.

Proper leveling and securing usually eliminate vibration. If vibration persists with correct installation, check for a loose pump or internal mounting issue.
