Care and maintenance
Switching the appliance off
Disconnect your appliance from the electricity supply before
carrying out any work on it.
Cleaning the appliance
!
Do not use abrasive or corrosive detergents (for example,
products in spray cans for cleaning barbecues and ovens),
stain removers, anti-rust products, powder detergents or
sponges with abrasive surfaces: these may scratch the
surface beyond repair.
!
Never use steam cleaners or pressure cleaners on the
appliance.
• It is usually sufficient simply to wash the hob using a damp
sponge and dry it with absorbent kitchen towel.
• If the hob is particularly dirty, rub it with a special glass
ceramic cleaning product, then rinse well and dry
thoroughly.
• To remove more stubborn dirt, use a suitable scraper.
Remove spills as soon as possible, without waiting for
the appliance to cool, to avoid residues forming crusty
deposits. You can achieve excellent results by using a
rust-proof steel wire sponge - specifically designed for
glass ceramic surfaces - soaked in soapy water.
• If any plastic or sugary substances are accidentally
melted on the hob, remove them immediately with the
scraper, while the surface is still hot.
• Once it is clean, the hob may be treated with a special
protective maintenance product: the invisible film left
by this product protects the surface from drips during
cooking. This maintenance task should be carried out
while the appliance is warm (not hot) or cold.
• Always remember to rinse the appliance well with clean
water and dry it thoroughly: residues can become
encrusted during subsequent cooking processes.
Stainless steel frame
(only in models with outer frame)
Stainless steel can be marked by hard water which has been
left on the surface for a long time, or by cleaning products
containing phosphorus.
After cleaning, it is advisable to rinse the surface well and dry
it thoroughly. If water is spilt on the surface, dry it quickly and
thoroughly.
!
Some hobs have an aluminium frame which is similar to
stainless steel. Do not use any cleaning or degreasing
products which are not suitable for use with aluminium.
Disassembling the hob
If it is necessary to disassemble the hob:
1. Loosen the screws fixing the alignment springs on each
side.
2. Loosen the screws holding the fixing hooks in each corner.
3. Take the hob out of its installation cavity.
!
Do not attempt to repair the appliance yourself. If the
appliance breaks down, contact a Service Centre.
