User Manual Induction Cooktop

Causes of damage

NOTICES

  • Scratches on glass ceramic surface: Cookware with rough bottoms will scratch the glass ceramic surface.
  • Salt, sugar and sand: Salt, sugar or grains of sand will scratch the glass ceramic surface. Never use the cooktop as a working surface or for setting things down
  • Overheated cookware: Avoid heating pots or pans that are empty.
  • Hot cookware: Never set down hot pans and pots on the control panel or frame. This may cause damage.
  • Hard and sharp objects: Hard or sharp objects falling on the cooktop may damage it.
  • Boiled-over food: Sugar and products containing sugar may damage the cooktop. Immediately eliminate spills of these products with a glass scraper.
  • Foils and plastics: Aluminum foil and plastic will melt on the hot cooking zones. Stove protective film isn't suitable for your cooktop
  • Unsuitable cleaning agent: Shimmering metallic discolorations on the glass ceramic surface result from the use of inappropriate cleaning agents and abrasion from cookware.

Protecting the environment

Energy-saving advice

  • Always place a fitting lid on cookware. Cooking with an uncovered pan will result in a four-fold increase in energy use. Use a glass lid to provide visibility and avoid having to lift the lid.
  • Use cookware equipped with a solid, flat bottom. Curved pan bases increase energy consumption.
  • The diameter of the pan base must match the size of the element. If not, energy may be wasted. Note: The manufacturer normally indicates the pan's upper diameter. This is normally greater than the diameter of the pan's base.
  • Choose cookware of a size suited to the amount of food you are going to cook. A large pan that is only half full will use a lot of energy.
  • Use a small amount of water when cooking. This saves energy, and vegetables retain a larger percentage of their vitamins and minerals.
  • Select a lower power level.

Cooking with Induction

Advantages of induction cooking

  • Saves time when boiling and frying.
  • Saves energy.
  • Easier to care for and clean. Spilled food does not burn on as quickly.
  • Heat control and safety – the cooktop increases or decreases the heat supply as soon as the user changes the setting. The induction element stops the heat supply as soon as the cookware is removed from the element, without having to switch it off first.

Cookware

Only use ferromagnetic cookware for induction cooking, such as:

  • Cookware made from enameled steel
  • Cookware made from cast iron
  • Special induction-compatible cookware made from stainless steel.

To check whether your cookware is suitable for induction cooking, refer to the section on → "Suitability test of cookware".

To achieve a good cooking result, the ferromagnetic area on the base of the pan should match the size of the element. If a element does not detect an item of cookware, try placing it on another element with a smaller diameter

Some induction cookware does not have a fully ferromagnetic base:

  • If the base of the cookware is only partially ferromagnetic, only the area that is ferromagnetic will heat up. This may mean that heat will not be distributed evenly. The non-ferromagnetic area may not heat up to a sufficient temperature for cooking.
  • The ferromagnetic area will also be reduced if the material of which the base of the cookware is made contains aluminum, for example. This may mean that the cookware will not become sufficiently hot or even that it will not be detected.

Unsuitable cookware

Do not ever use adapter plates for induction or cookware made of:

  • Traditional stainless steel
  • Glass
  • Clay
  • Copper
  • Aluminum

Properties of the base of the cookware

The material(s) of which the base of the cookware is made can affect the cooking result. Using pots and pans made from materials that distribute heat evenly through them, such as stainless-steel pans with a three-layer base, saves time and energy. Use cookware with a flat base; if the base of the cookware is uneven, this may impair the heat supply.

No pan or improper size

If no pan is placed on the selected element, or if it is made of unsuitable material or is not the correct size, the power level displayed on the element indicator will flash. Place a suitable pan on the element to stop the flashing. If you take longer than 90 seconds to place a suitable pan on the element, it will automatically turn off.

Empty pans or pans with a thin base

Do not heat up empty pans, or use pans with a thin base. The cooktop is equipped with an internal safety system. However, an empty pan may heat up so quickly that the "automatic switch off" function may not have time to react and the pan may reach very high temperatures. The pan base could melt and damage the cooktop glass. In this case, do not touch the pan and switch the cooktop off. If the cooktop fails to work after it has cooled down, please contact the technical service.

Pan detection

Each element has a lower limit for pan detection. This depends on the diameter of the ferromagnetic area of the cookware and the material of which its base is made. For this reason, you should always use the element that best matches the diameter of the base of the pan.

AutoChef®

When you are using AutoChef® to operate the heating element, a sensor controls the temperature of the pan

Advantages when frying

  • The element only heats up if this is required to maintain the temperature. This saves energy and prevents the oil or fat from overheating.
  • The AutoChef® function reports when the empty frying pan has reached the optimum temperature for adding oil and then for adding the food.

CAUTION

  • Never leave oil or fat cooking unattended.
  • Place the pan in the centre of the element. Make sure that the base of the pan has the proper diameter.
  • Do not cover the pan with a lid. The automatic regulation will not work. A mash splatter guard can be used without affecting the automatic regulation.
  • Only use fat or oil that is suitable for frying. When you are using butter, margarine, olive oil or pork lard, select the min temperature setting.
  • AutoChef® is not suitable for boiling.

Suitable pans for AutoChef®

Suitable frying pans for use with AutoChef® are available as optional accessory. Only use pans that are suitable for use with AutoChef®. You can buy our system pans in specialized stores, or through our Technical Assistance Service. Always indicate the related reference code.

  • HEZ390210 (Small)
  • HEZ390220 (Medium)
  • HEZ390230 (Large)

The frying pans have a non-stick coating, which means that very little oil is needed for frying.

CAUTION

  • The AutoChef® function was set especially for this type of frying pan.
  • Other frying pans may overheat. The temperature can be set higher or lower. Try the lowest heat setting first and then change it according to your requirements.
  • Make sure that the diameter of the base of the frying pan corresponds to the size of the element. Place the pan in the centre of the element.
  • If a different type of pan is used, try it first at the lowest frying level, adjusting it as required. The pans may overheat.

Cleaning and Maintenance

Daily Cleaning

Note: : Bosch cleaners have been tested and approved for use on Bosch appliances. Other recommended cleaners do not constitute an endorsement of a specific brand.

Glass ceramic cooktop

CAUTION Do not use any kind of cleaner on the glass while the surface is hot, use only the razor blade scraper. The resulting fumes can be hazardous to your health. Heating the cleaner can chemically attack and damage the surface.

Clean the surface when it is completely cool with the following exception: remove dry sugar, sugar syrup, tomato products and milk immediately with the razor blade scraper (see special care chart).

Wipe off spatters with a clean, damp sponge or a paper towel. Rinse and dry. Use white vinegar if smudge remains; rinse. Apply a small am

Apply a small amount of the glass ceramic cooktop cleaner. When dry, buff surface with a clean paper towel or cloth.

Stainless steel side trim

Wipe with the grain when cleaning. For moderate/heavy soil, use BonAmi® or Soft Scrub® (no bleach). Wipe using a damp sponge or cloth, rinse and dry.

Cleaning guidelines

When using a cleaner, use only a small amount; apply to a clean paper towel or cloth. Wipe on the surface and buff with a clean dry towel.

For best results, use a glass cooktop cleaner such as the Bosch Glass Cooktop Cleaner (part number 12010030), which can be ordered online at www.bosch-home.com/ us/store (for U.S. customers only). Other cleaners include Bon Ami®, Soft Scrub® (without bleach), and white vinegar.

Avoid these cleaners

  • Glass cleaners which contain ammonia or chlorine bleach. These ingredients may damage or permanently stain the cooktop.
  • Caustic cleaners - cleaners such as Easy Off® may stain the cooktop surface.
  • Abrasive cleaners.
  • Metal scouring pads and scrub sponges such as Scotch Brite® can scratch and/or leave metal marks.
  • Soap-filled scouring pads such as SOS® can scratch the surface.
  • Powdery cleaners containing chlorine bleach can permanently stain the cooktop.
  • Flammable cleaners such as lighter fluid or WD-40.

Cleaning charts

  • Dry sugar, sugar syrup, milk or tomato spills. Melted plastic film or foil. All these items REQUIRE IMMEDIATE REMOVAL. Failure to remove these immediatly can permanently damage the surface.
    • Remove these types of spills while the surface is hot using the razor blade scraper. Use a new, sharp razor in the scraper. Remove pan and turn off the element. Wearing an oven mitt, hold scraper at 30° angle, using care not to gouge or scratch the glass. Push soil off the heated area. After the surface has cooled, remove the residue and apply the glass ceramic cooktop cleaner.
    • WARNING RISK OF INJURY The blade is extremely sharp. Risk of cuts. Protect the blade when not in use. Replace the blade immediately when any imperfections are found. Follow manufacturer’s instructions.
  • Burned-on food soil, dark streaks, and specks
    • Soften by laying a damp paper towel or sponge on top of soil for 30 minutes. Use a plastic scrubber and glass ceramic cooktop cleaner or use the razor blade scraper. Rinse and dry.
  • Greasy spatters
    • Use a soapy sponge or cloth to remove grease; rinse thoroughly and dry. Apply glass ceramic cooktop cleaner.

      • You can find instructions on how to deactivate the audible signal in the section on → "Basic settings"
  2. Noises
    • Why I can hear noises while I'm cooking?
      • Noises may be generated while using the cooktop depending on the base material of the cookware. These noises are a normal part of induction technology. They do not indicate a defect.
    • Possible noises:
      • A low humming noise like the one a transformer makes:
        • Occurs when cooking at a high heat setting. The noise disappears or becomes quieter when the heat setting is reduced.
      • Low whistling noise:
        • Occurs when the cookware is empty. This noise disappears when water or food is added to the cookware.
    • Crackling:
      • Occurs when using cookware made from different layers of material or when using cookware of different sizes and different materials at the same time. The volume of the noise can vary depending on the quantity of food being cooked or the cooking method.
    • High-pitched whistling noises:
      • Can occur when two elements are used on the highest heat setting at the same time. The whistling noises disappear or become quieter when the heat setting is reduced.
    • Fan noise:
      • The cooktop is equipped with a fan that switches on automatically at high temperatures. The fan may continue to run even after you have switched off the cooktop if the temperature detected is still too high.
  3. Cleaning
    • How do I clean the cooktop?
      • Using a special glass-ceramic cleaning agent produces the best results. We advise against using harsh or abrasive cleaning agents, dishwater detergent (concentrated) or scouring pads.
      • You can find more information about cleaning and caring for your cooktop in the section on

Suitability test of cookware

This function can be used to check the speed and quality of the cooking process depending on the cookware.

The result is a reference value and depends on the properties of the cookware and the element being used.

  1. With the cookware still cold, fill it with approx. 8 oz. (200 ml) of water and place it on the center of the cooking zone with the diameter that most closely matches that of the base of the cookware.
  2. Go to the basic settings and select the @ setting.
  3. Touch the settings range @ will flash on the cooking zone display. The function has now been activated.

After 10 seconds, the result for the quality and speed of the cooking process will appear on the cooking zone display.

@ The cookware is taking longer to heat up than expected and the cooking process is not going as well as it ought to.*

@ The cookware is heating up correctly and cooking is progressing well.

* If there is a smaller element available, try the cookware again on the smaller element.

To reactivate this function, touch the settings range.

Notes

  • If the diameter of the used cooking zone is much smaller than the diameter of the cookware, only the middle of the cookware can be expected to heat up. This may result in the cooking results not being as good as expected or being less than satisfactory.
