Cleaning and maintenance

Cleaning

Once the appliance is cool, use a sponge to clean it with soap
and water.
After each use, clean the surface of the respective burner parts
once they have cooled down. If any residue is left (baked-on
food, drops of grease etc.), however little, it will become stuck
to the surface and more difficult to remove later. The holes and
grooves must be clean for the flame to ignite properly.
The movement of some pans may leave metal residue on the
pan supports.
Clean the burners and pan supports using soapy water and
scrub with a non-wire brush.
If the pan supports are fitted with rubber rests, ensure that
these are also cleaned. The rests may come loose and the pan
support may scratch the hob.
Always dry the burners and pan supports completely. Water
droplets or damp patches on the hob at the start of cooking
may damage the enamel.
After cleaning and drying the burners, make sure the burner
caps are correctly positioned on the diffuser.

Trouble shooting

Sometimes certain faults detected can be easily resolved.
Before calling the Technical Assistance Service, bear in mind
the following advice:
Fault
The general electrical sys-
tem is malfunctioning.
The automatic switching on
function does not work.
The burner flame is not uni-
form.
The gas flow is not normal
or there is no gas.
The kitchen smells of gas. A gas tap has been left on.
The safety valves on one of
the burners are not work-
ing.
Possible cause
Defective fuse.
The automatic safety switch or circuit breaker has
tripped.
There may be food or cleaning products stuck
between the ignition sparkers and the burners.
The burners are wet.
The burner caps are not correctly positioned.
The appliance is not earthed, is poorly connected
or the earthing is faulty.
The burner components are not correctly posi-
tioned.
The grooves on the burner are dirty.
The gas supply is blocked via intermediary valves. Open all gas taps.
If the gas is supplied from a gas cylinder, check
that this is not empty.
Incorrect coupling of gas cylinder.
Possible gas leak.
The control knob was not held down for long
enough.
The grooves on the burner are dirty.
Caution!
Do not use steam cleaners. This could damage the hob.
■
Never use abrasive products, steel scourers, sharp
■
implements, knives, etc. to remove bits of hardened food
from the hob.
Do not use knives, scrapers or similar implements to clean
■
the point where the glass meets the burner trims, the metal
frames or the glass/aluminium panels, if fitted.

Maintenance

Always clean off any liquid as soon as it is spilt. This will
prevent food remains from sticking to the hob surface and you
will save yourself any unnecessary effort.
Never slide pans across the glass surface, as you may scratch
it. In addition, try not to drop heavy or sharp objects on the
glass. Never strike any part of the hob.
Grains of sand that may come from cleaning fruits and
vegetables will scratch the glass surface.
Melted sugar, or foods which contain a lot of sugar which may
have spilt, should be cleaned off the hotplate immediately,
using the glass scraper.
Solution
Check the fuse in the main fuse box and change it
if it is damaged.
Check the main control panel to see if the auto-
matic safety switch or circuit breaker has tripped.
The space between the ignition sparker and the
burner must be clean.
Dry the burner caps carefully.
Check that the covers are correctly positioned.
Contact the installation technician.
Ensure the components are correctly positioned.
Clean the grooves on the burner.
Change the gas cylinder.
Turn off the taps.
Check that the coupling is sound.
Shut off the gas supply, ventilate the premises and
immediately notify an authorised installation tech-
nician so that they can check and certify the instal-
lation. Do not use the appliance until you are sure
that there is no gas leak in the installation or appli-
ance itself.
Once the burner is on, hold the control knob down
a few seconds longer.
Clean the grooves on the burner.
