Maintenance and care

Disconnect your appliance from the electricity

supply before carrying out any work on it.

! Do not use abrasive or corrosive detergents such

as stain removers, anti-rust products, powder

detergents or sponges with abrasive surfaces: these

may scratch the surface beyond repair.

! Never use steam cleaners or pressure cleaners on

the appliance.

• It is usually enough to wash the hob with a damp

sponge and dry it with absorbent kitchen roll.

• The removable parts of the burners should be

washed frequently with warm water and soap and

any burnt-on substances removed.

• For hobs which ligth automatically, the terminal

part of the electronic instant lighting devices

should be cleaned frequently and the gas outlet

holes should be checked for blockages.

• Stainless steel can be marked by hard water that

has been left on the surface for a long time, or by

aggressive detergents containing phosphorus.

After cleaning, rinse and dry any remaining drops

of water.

! Do not use stainless steel flame spreaders,

bread toasters or meat grills over gas flames.

Over time, the taps may become jammed or difficult

to turn. If this happens, the tap must be replaced.

! This procedure must be performed by a

qualified technician authorised by the

manufacturer.
