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.
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.

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 by gas taps.
If the gas is supplied from a gas cylinder, check
that it 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.
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.
Do not clean individual parts of the appliance in the
dishwasher.
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.
Caution!
The stainless steel cleaner must not be used in the area around
the controls. The (printed) symbols may be wiped off.
Thoroughly remove spilt cooking oil and acidic foodstuffs such
as lemon immediately.
Under no circumstance should abrasive cleaning powder be
used to clean the control panel. The inscriptions can be
scratched off as a result.
The burner caps are coated with black enamel. Due to the high
temperatures, discolouration may occur. Their burner function
is not adversely affected by this.
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 burner caps are correctly posi-
tioned.
Contact the installation technician.
Correctly place the parts on the appropriate
burner.
Clean the grooves on the burner.
Open all gas taps.
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 techni-
cian to check and certify the installation. Do not
use the appliance until ensuring that there is no
gas leak in the installation or appliance itself.
Once the burner is on, hold the control knob down
a few seconds longer.
Clean the grooves on the burner.
