Noises
Why I can hear noises while I'm cooking?
Noises may be generated while using the cooktop depending on the base material of the cookware. These
noises are a normal part of induction technology. They do not indicate a problem.
Possible noises:
A low humming noise like the one a transformer makes:
Occurs when cooking at a high heat setting. The noise disappears or becomes quieter when the heat set-
ting is reduced.

Possible Solution
Use a soapy sponge or cloth to remove grease; rinse
thoroughly and dry. Apply glass ceramic cooktop
cleaner.
Pans with aluminum, copper or stainless steel bases may
leave marks. Treat immediately after surface has cooled
with glass ceramic cooktop cleaner. If this does not
remove the marks, try a mild abrasive (Bon Ami®, Soft
Scrub® without bleach) with a damp paper towel. Rinse
and reapply glass ceramic cooktop cleaner. Failure to
remove metal marks before the next heating makes
removal very difficult.
Minerals in some water can be transferred onto the sur-
face and cause stains. Use undiluted white vinegar, rinse
and dry. Recondition with glass ceramic cooktop cleaner.
Remove boilovers and stains before using the cooktop
again.
Apply glass ceramic cooktop cleaner before using to
remove sand-like grains and grit such as salt and sea-
soning. Scratches can be reduced by using pans with
bases that are smooth, clean, and dry before use. Use
recommended glass ceramic cooktop cleaner daily.
NOTICE: Diamond rings may scratch the surface.
