Getting familiar with the appliance

In this section we describe the control panel, elements and displays.

These instructions apply to more than one cooktop, your appliance might vary slightly.

Page 2 contains a list of models and dimensions.

Control Panel

Touch control zone

When you touch a symbol, the corresponding function will be activated.

Notes

• When you touch several symbols at once, for example when food spills over, the settings will not change.
• Always keep the touch control zones clean and dry.
• Moisture and dirt can affect proper functioning.

Heating elements

Residual heat indicator

The cooktop is equipped with a residual heat indicator for each element. It shows you which elements are still hot. Avoid touching the indicated elements.

If an is shown on the display, the element is still hot. You could use it, for example, to keep a small quantity of

food warm or to melt a chocolate coating. As the element continues to cool, the display changes to . The display goes out once the element has cooled sufficiently.

The residual heat indicator will automatically come on after a power failure. The display lights up for approximately 30 minutes.

Operation

Main power switch

Use the main switch to turn on the electronic circuitry for the control panel. The cooktop is now ready to use.

Turning the cooktop on

Touch the On/Off touch key until the indicator above the main switch and the temperature level indicators next to the heating elements turn on.

Turning the cooktop off

Touch the On/Off touch key. The indicator above the On/ Off key goes out. The cooktop is switched off. The residual heat indicators will remain on until the elements have cooled off sufficiently.

Notes

• The cooktop switches off automatically when all the elements have been switched off for more than 10 seconds.
• The residual heat indicator remains lit until the elements have cooled down sufficiently. is displayed next to the corresponding element symbol.

Setting the cooktop

This section will show you how to set the elements. The table contains details on the heat settings for a variety of dishes.

Setting the element

Select the desired heat level using the number keys 1 to 9.

Heat level 1 = minimum power

Heat level 9 = maximum power

Each heat setting has an intermediate level. This level is indicated by . in the element display and is set by touching the symbols between the number keys.

Selecting the heat level

The cooktop must be turned on.

1. Touch the key for the desired element. The and _ indicators light up.
2. Within the following 10 seconds set the desired heat setting using the number keys. To set an intermediate level touch the symbols between the number keys.

Changing the heat level

Select the element and set the desired heat level using the number keys.

Turning off the element

Select the element and set the heat level to 0. The element is turned off and the residual heat indicator is displayed.

Note: The heat is turned on and off to regulate the temperature of the element; this means that the red glow below the element is not always visible. When you select a low heat setting, the element turns off for longer intervals, while at a higher setting these intervals are very short. Even at the highest level, the element turns on and off.

Settings table

The following table provides some examples. Cooking times may vary depending on the type of food, its weight and quality. Deviations are therefore possible.

Set the element to heat setting 9 for bringing to the boil or initial frying, then switch back to appropriate setting (not for melting).

Stir thick liquids occasionally. Food that needs to be seared quickly or food which loses a lot of liquid during initial frying is best seared in several small portions. Tips for energy-saving cooking can be found in section -> "Protecting the Environment"

CAUTION: During cooking, stews or liquid meals such as soups, sauces or drinks can heat up too quickly unnoticed and overflow or spatter. For this reason we recommend that you stir continuously, gradually heating the food at a suitable power level.

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 cleaning 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 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.

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.

Service

Before Calling for Service

Before calling Customer Service, consider the suggestions and instructions below:

CAUTION: Repairs should only be done by an authorized servicer.
Improper repair of your appliance may result in risk of severe physical injury or death.

The electronics of your cooktop are underneath the control panel. For various reasons, the temperature in this area may rise sharply.

In order that the electronics do not overheat, the cooking zones are switched off as and when necessary. The , or indicator appears alternately with the [IMAGE] or [IMAGE] residual heat indicator.

Indicator	Error	Task
None	There is no power supply.	Check the household fuse for the appliance. Check whether there is a power outage by trying other electronic appliances.
All indicators flash	The touch controls are wet or an object is resting on them.	Dry the controls or remove the object.
	Several cooking zones have been used over a prolonged period at high power settings. To protect the electronics, the cooking zone has been switched off.	Wait a while. Touch any control. When goes out, the electronics have cooled down sufficiently. You can continue cooking.

	The cooking zone was in operation for too long and has switched itself off.	You can switch the cooking zone back on again immediately.

Notes

• The cooktop regulates the heating element temperature by turning the heat source on and off; this means that the reddish glow of the heat source beneath the heating element may not always be visible. If you select a low heat setting, the heat source is frequently off; at higher settings it is seldom off. The source turns on and off even at the highest settings.
• You may hear a quiet hum when the heating elements are in the heating phase. The heating elements may glow with different levels of brightness. Depending on the angle from which you are looking at the heating element, this glow may be visible over the marked edge of the heating element. These are technical characteristics. They have no effect on quality and function.
• Glass ceramic may have uneven areas on the surface due to the nature of the material itself. Because of the mirror-like finish on the cooking surface, even extremely small bubbles less than 1 mm in diameter may be visible. These bubbles will not have any adverse effect on the operation of the cooktop nor on the durability of the glass ceramic cooking surface.
• Depending on the countertop that is present in the kitchen, an uneven gap between the cooktop unit and the countertop can occur. For this reason, a flexible seal is provided around the entire cooktop unit.
