Care and maintenance
Clean the hob after each use in order to avoid damaging
the surface and to prevent the formation of baked-on
deposits which are difficult to remove. Before cleaning,
make sure the cooking zones are switched off and that the
residual heat indicator (“H”) is not displayed.
• Never clean the hob with a steam cleaner!
• Periodically check for dust under the
appliance, near the cooling air inlet or the
outlet openings. This could hinder the
ventilation and cooling of the electronic
module and decrease the effectiveness of the
hob.
To clean the hob, proceed as follows:
1. use a soft clean cloth, absorbent kitchen wipes or a
proprietary cleaner for glass ceramic hobs. Do not use
abrasive sponges and/or metal scouring pads.
2. Food spills should be cleaned off before they bake
onto the glass ceramic surface. Sugar and foods with a
high sugar content damage the glass ceramic surface
and must be immediately removed using a scraper for
glass. Caution! Glass scrapers have a very sharp blade
and must be handled with care.
3. Remove any stubborn food residues with a scraper or
proprietary detergents.
4. Salt, sugar and sand can scratch the glass ceramic hob:
clean up any such spills on the hob immediately.
