Dishwasher vibrates excessively or moves during operation.

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

Steps:

• Level the appliance: Use a spirit level on the front and sides. Adjust the front and rear feet until the unit is stable and level.
• Secure to cabinet: Check that the mounting brackets are firmly screwed to the countertop or side cabinets.
• Balance the load: Avoid placing all heavy pots on one side of the lower rack.

When to call a technician: If vibration persists despite proper leveling and securing, there may be an internal mechanical issue requiring professional inspection.
