2Cleaning and maintenance

C leaning

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.

resolved. Before calling the Technical Assistance

Service, bear in mind the following advice:

Fault

The general electrical system

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.

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 positioned.

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.

A gas tap has been left on.

Incorrect coupling of gas cylinder.

Possible gas leak.

Caution!

Do not remove the control knobs when cleaning the

■

appliance. The appliance may be damaged if

moisture finds its way inside.

Do not use steam cleaners. This could damage the

■

hob.

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.

Due to the high temperatures endured, the wok burner

and the stainless steel zones (grease drip tray, burner

outline, etc.) can change colour. This is normal. After

each use, clean these areas with a product that is

suitable for stainless steel.

It is recommended that the cleaning product available

from our Technical Assistance Service (code 311499)

is used regularly.

Caution!

The stainless steel cleaner must not be used in the area

around the controls. The (printed) symbols may be

wiped off.

Do not leave acidic liquids (e.g. lemon juice, vinegar,

etc.) on the hob.

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 automatic 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 positioned.

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 imme-

diately notify an authorised installation technician 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.
