Possible cause
interrupted.
The appliance has not been cor-
rectly connected following the con-
nection diagram.
Electronic system malfunction.
The touch control zone is wet, very
dirty, food has boiled over, or an
object is lying on top of the touch
control zone.
The main switch has been activated
continuously for more than 5 sec-
onds.
The main switch has been touched
unintentionally.
Possible Solution
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.
