Preventing material damage

2.1 General
ATTENTION!
Objects on the cooking compartment floor at over 50 °C will cause heat to build up. The baking and roasting times will no longer be correct and the enamel will be damaged.

Do not place any accessories, greaseproof paper or foil of any kind on the cooking compartment floor.
Only place cookware on the cooking compartment floor if a temperature above 50 °C has been set.
When the cooking compartment is hot, any water inside it will create steam. The change in temperature may cause damage.
Never pour water into the cooking compartment when it is still hot.
Never place cookware containing water on the cooking compartment floor.
The prolonged presence of moisture in the cooking compartment leads to corrosion.
Allow the cooking compartment to dry after use.
Do not keep moist food in the cooking compartment for a long time with the door closed.
Do not store food in the cooking compartment.
Leaving the appliance to cool down with the door open will damage the front of neighbouring kitchen units over time.
Always allow the cooking compartment to cool down with the door closed after cooking at high temperatures.
Take care not to trap anything in the appliance door.
Only leave the cooking compartment to dry with the door open if a lot of moisture was produced during operation.
Fruit juice dripping from the baking tray leaves stains that cannot be removed.
When baking very juicy fruit flans, do not pack too much on the baking tray.
If possible, use the deeper universal pan.
Using oven cleaner in a hot cooking compartment damages the enamel.
Never use oven cleaner in the cooking compartment when it is still warm.
Remove all food remnants from the cooking compartment and the appliance door before you next heat up the appliance.
If the seal is very dirty, the appliance door will no longer close properly during operation. This may damage the front of adjacent kitchen units.
Keep the seal clean at all times.
Never operate the appliance if the seal is damaged or missing.
Sitting or placing objects on the appliance door may damage it.
Do not place or hang objects on the appliance door.
Do not place cookware or accessories on the appliance door.

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 power.
Only preheat the appliance if the recipe or the recommended settings tell you to do so.

Not preheating the appliance can reduce the energy used by up to 20%.
Use dark-coloured, black-coated or enamelled baking tins.
These types of baking tin absorb the heat particularly well.

Open the appliance door as little as possible during operation.

This will maintain the temperature in the cooking compartment and eliminate the need for the appliance to reheat.
When baking multiple dishes, do so in succession or in parallel.
The cooking compartment is heated after baking the first dish. This reduces the baking time for the second cake.
If the cooking time is relatively long, you can switch the appliance off 10 minutes before the cooking time ends.
There will be enough residual heat to finish cooking the dish.
Remove any accessories that are not being used from the cooking compartment.
Accessories that are not being used do not need to be heated.
Allow frozen food to defrost before cooking.
This will save the energy that would otherwise be required to defrost it.

4.6 Cooking compartment
The functions in the cooking compartment make your appliance easier to use.
Shelf supports
The rails in the cooking compartment enable you to place accessories at different heights. → “Accessories”, Page 9
Your appliance has three shelf positions. The shelf positions are numbered from bottom to top.
The rails are equipped with pull-out rails on one or more levels, depending on the appliance type.
You can remove the rails, e.g. for cleaning. → “Rails”, Page 19

Self-cleaning surfaces
The self-cleaning surfaces in the cooking compartment are coated with a porous, matt ceramic layer and have a rough surface. When the appliance is in operation, the self-cleaning surfaces absorb splashes from roasting or grilling and break them down.
The following surfaces are self-cleaning:

Back wall
Ceiling
Side walls

Use the cleaning function regularly to help retain the cleaning ability of the self-cleaning surfaces and prevent damage. → “Cleaning function EcoClean”, Page 18

Lighting
One or more oven lights illuminate the cooking compartment.

For most operating modes, the lighting is switched on during operation. The lighting switches off again when the operation ends.
Cooling fan
The cooling fan switches on and off depending on the appliance’s temperature. The hot air escapes above the door.
ATTENTION!
Do not cover the ventilation slot above the appliance door. The appliance overheats.
▶ Ensure that the ventilation slots are unobstructed.
To ensure that the appliance cools down more quickly after operation, the cooling fan continues to run for a certain period afterwards.
Appliance door
If you open the appliance door during operation, the operation stops. When you close the appliance door, the operation continues automatically.

5.1 Types of heating
To ensure that you always use the right type of heating to cook your food, we explain the differences and applications below.
The symbols for each type of heating help you to remember them.
When you select a type of heating, the appliance suggests a suitable temperature or setting. You can use these values or change them within the specified range.
For temperature settings above 275 °C and grill setting 3, the appliance reduces the temperature to approx. 275 °C or grill setting 1 after approx. 40 minutes.

Symbol| Type of heating| Temperature| What it’s used for and how it works Possible additional options
---|---|---|---
| 4D hot air| 30-275 °C| Bake and roast on one or more levels.
The fan distributes the heat from the ring-shaped heating element in the back wall evenly around the cooking compartment.
| Top/bottom heating| 30-300 °C| Traditionally bake or roast on one level. This type of heating is ideal for cakes with moist toppings.
The heat is emitted evenly from above and below.
| Hot air eco| 30-275 °C| Cook selected dishes gently on one level without preheating.
The fan distributes the heat from the ring-shaped heating element in the back wall evenly around the cooking compartment. The food is cooked in phases using residual heat.
This type of heating is most effective between 125 and 275 °C. Always keep the appliance door closed when cooking.
This type of heating is used to determine the energy consumption in air recirculation mode and the energy efficiency class.
| Top/bottom heating eco| 30-300 °C| Gently cook selected dishes.
Heat is emitted from above and below.
This heating function is most effective between 150 and 250 °C. This type of heating is used to measure the energy consumption in the conventional mode.
| Circulated air grilling| 30-300 °C| Roast poultry, whole fish or larger pieces of meat.
The grill element and the fan switch on and off alternately. The fan circulates the hot air around the food.
| Grill, large area| Grill settings:
1 = low
2 = medium
3 = high| Grill flat items such as steak and sausages, or make toast. Gratinate food.
The entire area below the grill element becomes hot.
| Grill, small area| Grill settings:
1 = low
2 = medium
3 = high| Grill small quantities, such as steak, sausages or toast. Gratinate small quantities of food.
The central area below the grill element becomes hot.
| Pizza setting| 30-275 °C| Cook pizza or dishes that require a lot of heat from below. The bottom heating element and the ring-shaped heating element in the back wall heat the cooking compartment.

Accessories

Use original accessories. These have been made especially for your appliance.
Note: Accessories may become deformed if they get hot. Deformation has no effect on function. As the accessory cools down, it will regain its original shape.
The accessories supplied may differ depending on the appliance model.
