2.1 Overview of the most common damage
Here you can find the most common types of damage and tips on how to avoid them.

Damage

| Cause|

Measure

---|---|---
Stains| Food boiling over| Remove boiled-over food immediately with a glass scraper.
Stains| Unsuitable cleaning products| Only use cleaning products that are suitable for glass ceramic.
Scratch es| Salt, sugar or sand| Do not use the hob as a work surface or storage space.
Scratch es| Rough pot or pan bases| Check your cookware.
Discol- ouration| Unsuitable cleaning products| Only use cleaning products that are suitable for glass ceramic.

Blisters| Sugar or food with a high sugar content| Remove boiled-over food immediately with a glass scraper.

Environmental protection and saving energy

3.1 Disposing of packaging
The packaging materials are environmentally compatible and can be recycled.
▶ Sort the individual components by type and dispose of them separately.
3.2 Saving energy
If you follow these instructions, your appliance will use less energy.
Select the cooking zone to match the size of your pan. Centre the cookware on the hob.
Use cookware whose base diameter is the same diameter as the hotplate.
Tip: Cookware manufacturers often give the upper diameter of the saucepan. It is often larger than the base diameter.

• Unsuitable cookware or incompletely covered cooking zones consume a lot of energy.
  Cover saucepans with suitable lids.

• Cooking without a lid consumes considerably more energy.

• Lift lids as infrequently as possible.

• When you lift the lid, a lot of energy escapes.
  Use a glass lid.

• You can see into the pan through a glass lid without having to lift it.
  Use pots and pans with flat bases.

• Uneven bases increase energy consumption.
  Use cookware that is suitable for the quantity of food.

• Large items of cookware containing little food need more energy to heat up.
  Cook with only a little water.

• The more water that is contained in the cookware, the more energy is required to heat it up.
  Turn down to a lower power level early on.

• If you use an ongoing power level that is too high, you will waste energy.
  Take advantage of the hob’s residual heat. With longer cooking times switch off the hotplate 5-10 minutes before the end of cooking.

• Unused residual heat increases energy consumption.

 Familiarising yourself with your appliance

The instruction manual is the same for various different hobs. You can find the hob dimensions in the overview of models. → Page 2
4.1 Control panel
You can use the control panel to configure all functions of your appliance and to obtain information about the operating status.

4.2 Indicators/symbols
The displays show selected values and functions.

| Residual heat
| Electronic boil start control

4.3 Touch fields
Touch fields are touch-sensitive surfaces. To select a function, touch the relevant field.

Notes

• Always keep the control panel dry. Moisture impairs the function.
• Do not pull pans close to the displays and touch fields. The electronics may overheat.

4.4 Hotplates
You can find an overview of the different activations of the hotplates here.
If you operate the activations, the relevant displays light up.
If you switch on a hotplate, it will switch to the setting last selected.

Notes

• Dark areas in the glow pattern of the hotplate are part of the technical design. They do not affect the functionality of the hotplate.
• The hotplate regulates the temperature by switching the heat on and off. The heat may also switch on and off when at the highest setting.
• With multi-circuit hotplates, the heating of the hotplate and the activated areas may switch on or off at different times.
  Reasons:
  – Easily damaged components are protected against overheating.
  – The appliance is protected against electrical overload.
  – This achieves a better cooking result.
