Hob vibrates loudly or buzzes excessively when induction zones are on.

User steps:

• Try different pans; multi‑layer or very thin bases can vibrate more on induction.
• Reduce the power setting slightly; noise often decreases at lower power.

Technician steps:

• Check that all induction coils are firmly mounted and that any damping pads are in place.
• Tighten chassis and mounting screws.
• Inspect the cooling fan for worn bearings or imbalance and replace if noisy.
