Induction hob makes loud buzzing or humming noises at certain power levels.

Safety first: Ensure cookware is stable and the hob surface is clean and dry.

• Try different cookware: Use heavier, flat-bottomed pans. Noise often reduces with better-quality cookware.
• Change power level: Slightly adjust the power setting; some noise is normal at high power or boost modes.
• Check mounting (advanced): With power disconnected, remove the hob and verify that the induction coils are firmly mounted and that all chassis screws are tight.

Note: A low-level hum is normal for induction hobs; only investigate if the noise is unusually loud or accompanied by error codes.
