Important: If the power supply is interrupted, the Samsung C21RJAN series img 13 symbol will go out and information about residual heat will no longer be available. However, it may still be possible to burn yourself. This can be avoided by always taking care when near the hob.

Before You Begin

Initial cleaning
Wipe the ceramic glass surface with a damp cloth and ceramic hob glass cleaner.
Samsung C21RJAN series img 1Important: Do not use caustic or abrasive cleaners. The surface could be damaged.

Hob Use

Using suitable cookware
Better pans produce better results.

  • You can recognize good pans by their bases. The base should be as thick and flat as possible.
  • When buying new pans, pay particular attention to the diameter of the base.
    Manufacturers often give only the diameter of the upper rim.
  • Pots with aluminium or copper bases can cause metallic discolouration on the ceramic glass surface. The discolouration is very difficult or impossible to remove.
  • Do not use pans made of cast iron or which have damaged bases with rough edges or burrs. Permanent scratching can occur if these pan are slid across the surface.
  • When cold, pan bases are normally bowed slightly inwards (concave). They should never be bowed outwards (convex).
    • If you wish to use a special type of pan, for example, a pressure cooker, a simmering pan, or a wok, please observe the manufacturer’s instructions.
    Energy saving tips
    Samsung C21RJAN series img 3You can save valuable energy by observing the following points. Samsung C21RJAN series img 19
  • Always position pots and pans before switching on the cooking zone.
  • Dirty cooking zones and pan bases increase power consumption.
  • When possible, position the lids firmly on the pots and pans to cover completely.
  • Switch the cooking zones off before the end of the cooking time to use the residual heat for keeping foods warm or for thawing. Samsung C21RJAN series img 20
  • The base of the pan should be the same size as the cooking zone.
  • Using a pressure cooker reduces cooking times by up to 50 %. Samsung C21RJAN series img 21

Cleaning and Care


Samsung C21RJAN series img 1Important: Cleaning agents must not come into contact with a heated ceramic glass surface: All cleaning agents must be removed with adequate amounts of clean water after cleaning because they can have a caustic effect when the surface becomes hot. Do not use any aggressive cleaners such as grill or oven sprays, scouring pads or
abrasive pan cleaners.

Samsung C21RJAN series img 2Clean the ceramic glass surface after each use when it is still warm to the touch. This will prevent spillage from becoming burnt onto the surface. Remove scales, watermarks, fat drippings and metallic discolouration with the use of a commercially available ceramic glass or stainless steel cleaner.

Light Soiling

  1. Wipe the ceramic glass surface with a damp cloth.
  2. Rub dry with a clean cloth. Remnants of cleaning agent must not be left on the surface.
  3. Thoroughly clean the entire ceramic glass cooking surface once a week with a commercially available ceramic glass or stainless steel cleaner.
  4. Wipe the ceramic glass surface using adequate amounts of clean water and rub dry with a clean lint – free cloth.

Stubborn Soiling

  1. To remove food that has boiled over and stubborn splashes, use a glass scraper.
  2. Place the glass scraper at an angle to the ceramic glass surface.
  3. Remove soiling by scraping with the blade.
    Samsung C21RJAN series img 2Glass scrapers and ceramic glass cleaners are available from specialty retailers. Samsung C21RJAN series img 33

Problem Dirt

  1. Remove burnt-on sugar, melted plastic, aluminium foil or other materials with a glass scraper immediately and while still hot.
    Samsung C21RJAN series img 1Important: There is a risk of burning yourself when the glass scraper is used on a hot cooking zone:
  2. Clean the hob as normal when it has cooled down.
    Samsung C21RJAN series img 2If the cooking zone on which something has melted has been allowed to cool, warm it up again for cleaning.
    Scratches or dark blemishes on the ceramic glass surface, caused, for example, by a pan with sharp edges, cannot be removed. However, they do not impair the function of the hob. Samsung C21RJAN series img 34

To avoid damaging your appliance

  • Do not use the hob as a work surface or for storage.
  •  Do not operate a cooking zone if there is no pan on the hob or if the pan is empty.
  • Ceramic glass is very tough and resistant to temperature shock, but it is not unbreakable. It can be damaged by a particularly sharp or hard object dropping onto the hob.
  • Do not use pans made of cast iron or which have damaged bases with rough edges or burrs. Scratching may occur if these pans are slid across the surface.
  • Do not place pans on the hob frame. Scratching and damage to the finish may occur.
  • Avoid spilling acidic liquids, for example, vinegar, lemon juice and descaling agents, onto the hob frame, since such liquids can cause dull spots.
  • If sugar or a preparation containing sugar comes into contact with a hot cooking zone and melts, it should be cleaned off immediately with a kitchen scraper while it is still hot. If allowed to cool, it may damage the surface when removed.
  • Keep all items and materials that could melt, for example, plastics, aluminium foil and oven foils, away from the ceramic glass surface. If something of this nature melts onto the hob, it must be removed immediately with a scraper.
