Cleaning and maintenance
72
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 pans, 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. Use of
corrosive detergents or rubbing of pan
bases 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 blown. In
this case replace the fuse.
• Make sure that the circuit breaker of the
residential electrical system has not
tripped. In this case, reset the circuit
breaker.
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 complete.
• Make sure that the food has not spilled
out of the pan and use a larger cooking
vessel, if needed.
The fuses blow or the circuit breaker of the
residential electrical system trips repeatedly.
• 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 Technical Support.
