Switching the appliance off
Disconnect your appliance from the electricity supply before carrying out
any work on it.
Cleaning the appliance

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.

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.

surface for a long time, or by aggressive detergents containing phosphorus.
After cleaning, rinse and dry any remaining drops of water.
