Cleaning and maintenance
44
Changes in colour
do not affect the
operation and stability of the glass. These
are not alterations to the material of the hob
but just residues which have not been
removed and have then carbonised.
Shiny surfaces
can form due to the bases
of saucepans, especially aluminium ones,
rubbing on the surface, and due to the use
of unsuitable detergents. They are difficult to
remove using conventional cleaning
products. It may be necessary to repeat the
cleaning process several times. Using
aggressive detergents, or friction with the
base of saucepans, can wear away the
decoration on the hob over time and
contribute to the formation of stains.
4.5 What to do if...
The hob does not work:
• Make sure that the hob is connected
and that the main switch is turned on.
• Make sure that there is no power failure.
• Make sure that the fuse has not tripped.
In this case replace the fuse.
• Make sure that the magneto thermal
switch of the residential electrical system
has not tripped. In this case, re-activate
the switch.
• Make sure that the sensor key are not
locked by the Control lock.
• Make sure that the keys are not partially
covered by a damp cloth, a liquid or a
metal object.
The cooking results are unsatisfactory:
• Make sure that the cooking temperature
is not too high or too low.
The hob smokes:
• Let the hob cool down and clean it once
cooking is finished.
• Make sure that the food has not come
out and use a larger cooking vessel, if
needed.
The display shows “E2”:
• Make sure that there is no spilled food
on the sensor keys.
• Remove any pan or object that are
partially resting on the sensor keys.
The display shows “E1 - E3 - E4 - E5”:
• There is a technical fault. Contact
Technical Support.
The fuses or the magneto thermal switch of
the residential electrical system are
repeatedly triggered.
• Call Technical Support or an electrician.
There are cracks or fissures in the hob:
• Turn off the appliance immediately,
disconnect the power supply and
contact the Technical Support.
