Multicooker vibrates excessively or moves on the countertop during operation.

Safety first: Ensure the cooker cannot fall from the counter. Unplug before turning it over.

Step-by-step checks:

• 1. Check rubber feet: Turn the cooker upside down (when cool) and inspect the rubber feet. Replace any missing or hardened feet.
• 2. Level surface: Place the cooker on a flat, stable surface. Avoid soft or uneven surfaces like stovetops or racks.
• 3. Tighten chassis screws: Remove the bottom cover and tighten any loose screws securing the internal frame.
• 4. Fan inspection (if present): On models with a cooling fan, check that the fan blades are clean and not damaged, which can cause imbalance.

Note: Mild vibration is normal, but the unit should not "walk" across the counter.
