8. CLEANING AND MAINTENANCE

. Before carrying out any maintenance work on the hob, allow it
to cool down.
. Only products, (creams and scrapers) specifically designed for
glass ceramic surfaces should be used. They are obtainable
from hardware stores.
. Avoid spillages, as anything which falls on to the hob surface
will quickly burn and will make cleaning more difficult.
. It is advisable to keep away from the hob all substances which
are liable to melt, such as plastic items, sugar, or sugar-based
products.
MAINTENANCE:
- Place a few drops of the specialised cleaning product on the
hob surface.
- Rub any stubborn stains with a soft cloth or with slightly damp
kitchen paper.
- Wipe with a soft cloth or dry kitchen paper until the surface is
clean.
If there are still some stubborn stains:
- Place a few more drops of specialised cleaning fluid on the
surface.
- Scrape with a scraper, holding it at an angle of 30° to the hob,
until the stains disappear.
- Wipe with a soft cloth or dry kitchen paper until the surface is
clean.
- Repeat the operation if necessary.
A FEW HINTS:
Frequent cleaning leaves a protective layer which is essential to
prevent scratches and wear. Make sure that the surface is clean
before using the hob again. To remove marks left by water, use a
few drops of white vinegar or lemon juice. Then wipe with
absorbent paper and a few drops of specialised cleaning fluid.
The glass ceramic surface will withstand scraping from flat-
bottomed cooking vessels, however, it is always better to lift them
when moving them from one zone to another.
NB:
- Do not use a sponge which is too wet.
- Never use a knife or a screwdriver.
- A scraper with a razor blade will not damage the surface, as long
as it is kept at an angle of 30°.
- Never leave a scraper with a razor blade within the reach of
children.
- Never use abrasive products or scouring powders.
• The metal surround : to safely clean the metal surround wash
with soap and water, rinse, then dry with a soft cloth.

9. PROBLEM SOLVING

The cooking zones do not simmer or only fry gently
Only use flat-bottomed pans. If light is visible between the pan
and the hob, the zone is not transmitting heat correctly.
The pan bottom should fully cover the diameter of the selected
zone.
The cooking is too slow
Unsuitable pans are being used. Only use flatbottomed
utensils, that are heavy and have a diameter at least the same
as the cooking zone.
Small scratches or abrasions on the hob's glass surface
Incorrect cleaning or rough-bottomed pans are used; particles
like grains of sand or salt get between the hob and the bottom
of the pan. Refer to the "CLEANING" section; make sure that
pan bottoms are clean before use and only use smooth
bottomed pans. Scratches can be lessened only the cleaning is
done correctly.
Metal marks
Do not slide aluminium pans on the hob. Refer to the cleaning
recommendations.
You use the correct materials, but the stains persist.
Use a razor blade and follow the "CLEANING" section.
Dark stains
Use a razor blade and follow the "CLEANING" section.
Light surfaces on the hob
Marks from an aluminium or copper pan, but also mineral, water
or food deposits; they can be removed using the cream cleaner.
Caramelisation or melted plastic on the hob.

the spill or remove the object.
The cooking zones stop automatically if they are left
on for too long. Refer to the section, "operating time".
Frequency of on/off operations for cooking zones
The on-off cycles vary according to the required heat level:
- low level: short operating time,
- high level: long operating time.
"H" display, residual heat indicator, blinking.
The electronic temperature is too high. A technician should
verify the fitting in compliance with the recommendations.

11. PROTECTION OF THE ENVIRONMENT

This appliance is marked according to the
European directive 2012/19/EU on Waste
Electrical and Electronic Equipment (WEEE).
WEEE contains both polluting substances
(which can cause negative consequences for
the environment) and basic components
(which can be re-used). It is important to have
WEEE subjected to specific treatments, in
order to remove and dispose properly all
pollutants, and recover and recycle all materials.
Individuals can play an important role in ensuring that WEEE
does not become an environmental issue; it is essential to
follow some basic rules:
• WEEE shall not be treated as household waste.
• WEEE shall be handed over to the relevant collection points
managed by the municipality or by registered companies. In
many countries, for large WEEE, home collection could be
present.
• When you buy a new appliance, the old one may be returned
to the retailer who has to collect it free of charge on a one-to-
one basis, as long as the equipment is of equivalent type and
has the same functions as the supplied equipment.
