If there is a red bar above or below a symbol, this means that the value being shown in large digits on the display refers to the function that this symbol represents.
Types of heating and functions
Use the function selector to set the types of heating and other functions.
To make sure you always use the right type of heating to cook your food, we have explained the differences and applications below.

Other functions
Your new oven has yet more functions; see below for a brief description of these.

Use the temperature selector to set the temperature in the cooking compartment. It can also be used to select the grill and cleaning settings, for example. The settings will appear on the display.

Cooking compartment
Various functions in the cooking compartment make your appliance easier to use. For example, the cooking compartment is well lit and a cooling fan prevents the appliance from overheating.
Opening the appliance door
If you open the appliance door when the appliance is in operation, the appliance will continue to operate as before. Interior lighting With most heating functions and other functions, the interior lighting in the cooking compartment will remain lit while the oven is in operation. When the function selector is turned to bring operation to an end, the lighting will go out. By turning the function selector to the interior lighting setting, you can switch on the lighting without heating the oven. This makes it easier to clean your appliance, for example.
Cooling fan
The cooling fan switches on and off as required. The hot air escapes above the door.
Caution! Do not cover the ventilation slots. Otherwise, the appliance may overheat. So that the cooking compartment cools down more quickly after operation, the cooling fan continues to run for a certain period afterwards.
Control accessories

Only use original accessories. They are specially adapted for your appliance. You can buy accessories from the after-sales service, from specialist retailers or online.
Note: The accessories may deform when they become hot. This does not affect their function. Once they have cooled down again, they regain their original shape.
Inserting accessories
The cooking compartment has four shelf positions. The shelf positions are counted from the bottom up.

Always insert accessories between the two guide rods for the shelf position. Accessories can be pulled out approximately halfway without tipping.
Locking function
The accessories can be pulled out approximately halfway until they lock in place. The locking function prevents the accessories from tilting when they are pulled out. The accessories must be inserted into the cooking compartment correctly for the tilt protection to work properly.
When inserting the wire rack, ensure that lug a ‚ is at the rear and is facing downwards. The open side must be facing the appliance door and the outer rail must be facing downwards
.
When inserting baking trays, make sure that the recess a ‚ is at the rear and is facing downwards. The sloping edge of the accessory b must be facing towards the appliance door. Example in the picture: Universal pan

Combining accessories
You can insert the wire rack and the universal pan at the same time to catch drops of liquid. When inserting the wire rack, ensure that both spacers a ‚ are at the rear edge. When inserting the universal pan, the wire rack is on top of the upper guide rod of the shelf position.
Example in the picture: Universal pan

Notes
Surfaces in the cooking compartment
The back wall in the cooking compartment is selfcleaning.You can tell this from the rough surface. The base, ceiling and side panel are enamelled and have smooth surfaces.
Cleaning enamel surfaces
Clean the smooth enamel surfaces with a dish cloth and hot soapy water or a vinegar solution. Then dry them with a soft cloth. Soften baked-on food remnants with a damp cloth and soapy water. Use stainless steel wire wool or oven cleaner to remove stubborn dirt.
Caution! Never use oven cleaner in the cooking compartment when it is still warm. This may damage the enamel. Remove all food remnants from the cooking compartment and the appliance door before you next heat up the appliance. Leave the cooking compartment open to dry after cleaning it.
Note: Food residues can cause white deposits to form. These are harmless and do not affect how the appliance works. You can remove these residues using lemon juice if required.
Cleaning self-cleaning surfaces
The self-cleaning surfaces are coated with a porous, matte ceramic layer. This coating absorbs and dispels splashes from baking and roasting while the appliance is in operation.
If the self-cleaning surfaces no longer clean themselves sufficiently and dark stains appear, they can be cleaned using targeted heating.
Making settings
Remove the rails, pull-out shelves, accessories and ovenware from the cooking compartment beforehand. Thoroughly clean the smooth enamel surfaces in the cooking compartment, the inside of the appliance door and the glass cover on the interior lighting.
The ceramic coating is regenerated. When the cooking compartment has cooled down, remove the brown or white residue with water and a soft sponge.
Note: During operation, reddish spots form on the surfaces. This is not rust, but residues from food. These spots are not harmful and do not restrict the cleaning ability of the self-cleaning surfaces.
Caution! Do not use oven cleaner on the self-cleaning surfaces. This will damage the surfaces.If oven cleaner does get onto these surfaces, dab it off immediately using water and a sponge cloth. Do not rub the surface and do not use abrasive cleaning aids.
After cleaning
After cleaning the door seal, check whether it is sitting correctly on the left- and right-hand side. (fig. 1).
If the door seal is running over the spacer a, push the door seal inwards so that it now runs beside the spacer a (fig. 2).

Keeping the appliance clean
Always keep the appliance clean and remove dirt immediately so that stubborn deposits of dirt do not build up.
Warning – Risk of fire! Loose food remnants, fat and meat juices may catch fire. Before using the appliance, remove the worst of the food remnants from the cooking compartment, heating elements and accessories.
Tips
Detaching and refitting the rails
Warning – Risk of burns! The rails become very hot. Never touch the hot rails. Always allow the appliance to cool down. Keep children away from the appliance.
Detaching the rails

1. Lift the rail slightly at the front a and detach it b. (fig. 1)
2. Then pull the whole rail to the front and remove it. (fig. 2)

Clean the rails with cleaning agent and a sponge. For stubborn dirt deposits, use a brush.
Attaching the rails
The rails only fit on the right or the left side. For both rails, ensure that the curved rods are at the front.
1. First, insert the rail in the middle of the rear socket a until the rail rests against the cooking compartment wall, and push it back b.
2. Then insert the rail into the front socket a, until the rail also rests against the cooking compartment wall here, and press it downwards b
