4 Cleaning and maintenance
4.1 Instructions
4.2 Cleaning the appliance
To keep the surfaces in good condition,
they should be cleaned regularly after use.
Let them cool first.
Ordinary daily cleaning
Always use specific products only that do
not contain abrasives or chlorine-based
acids.
Pour the product onto a damp cloth and
wipe the surface, rinse thoroughly and dry
with a soft cloth or a microfibre cloth.
Clean and maintain the hob once a week
using an ordinary glass cleaning product.
Always follow the manufacturer’s
instructions. The silicon in these products
creates a protective, water-repellent
membrane which also resists dirt. All marks
stay on the membrane and can therefore be
removed easily. After cleaning, dry the
surface with a clean cloth. Make sure that
there is no detergent left on the cooking
surface as it will undergo a corrosive
reaction when heated up and could modify
the structure of the cooking surface.
Annual service by an authorised person is
recommended, or if any of the following
conditions are noticed:
• Incomplete ignition;
• Appreciable yellow tipping;
• Carbon deposition;
• Lifting;
• Floating;
• Lighting back;
• Objectionable odour.
Improper use
Risk of damage to surfaces
• Do not use steam jets to clean the
appliance.
• Do not use cleaning products containing
chlorine, ammonia or bleach on parts
made of steel or that have metallic
surface finishes (e.g. anodizing, nickel-
or chromium-plating).
• Do not use harsh abrasive cleaners or
sharp metal scrapers to clean glass
since they can scratch the surface, which
may result in shattering of the glass.
• Do not use rough or abrasive materials
or sharp metal scrapers.
• Do not wash removable parts such as
the hob grids, flame-spreader crowns
and burner caps in the dishwasher.
• Do not use steam jets to clean the
appliance.
• Do not spill sugar or sweet mixtures on
the hob during cooking.
• Do not place materials or substances
that could melt (plastic or aluminium foil).
• Keep sensor keys clean at all times and
do not rest any object on them.
