The microwave

Microwaves are converted to heat in foodstuffs.
You can set the microwave on its own or in combination with 

the grill.
You will find information about ovenware and how to set the 

microwave.

Note: 

In the 

Tested for you in our cooking studio

 section, you 

will find examples for defrosting, heating, melting and cooking 

with the microwave oven.
Try out the microwave straight away. You could heat up a cup 

of water for your tea, for example.
Use a large cup without any decorative gold or silver trim and 

place a teaspoon in it. Place the cup containing the water on 

the turntable.

1.

Press 900 W.

2.

Set 1:30 minutes using the rotary knob.

3.

Press the Start button.

After 1 minute 30 seconds, a signal sounds. The water for the 

tea is hot.
As you are drinking your tea, please take time to read again the 

safety information that can be found at the front of the 

instruction manual. This is very important.

Notes regarding ovenware

Suitable ovenware

Suitable dishes are heat-resistant ovenware made of glass, 

glass ceramic, porcelain, ceramic or heat-resistant plastic. 

These materials allow microwaves to pass through.
You can also use serving dishes. This saves you having to 

transfer food from one dish to another. You should only use 

ovenware with decorative gold or silver trim if the manufacturer 

guarantees that they are suitable for use in microwaves.

Unsuitable ovenware

Metal ovenware is unsuitable. Metal does not allow microwaves 

to pass through. Food in covered metal containers will remain 

cold.

Caution!

 Creation of sparks: metal – e.g. a spoon in a glass – must be 

kept at least 2 cm from the oven walls and the inside of the 

door. Sparks could destroy the glass on the inside of the door.

Ovenware test

Do not switch on the microwave unless there is food inside. The 

following ovenware test is the only exception to this rule.
Perform the following test if you are unsure whether your 

ovenware is suitable for use in the microwave: 

1.

Heat the empty ovenware at maximum power for ½ to 

1 minute.

2.

Check the temperature occasionally during that time.

The ovenware should still be cold or warm to the touch.
The ovenware is unsuitable if it becomes hot or sparks are 

generated.

Microwave power settings

You can set the 900 W microwave power setting for 30

operation. The cooling fan will still switch on. The fan may run 

on even when microwave operation has ended.

■

Condensation may appear on the door window, interior walls 

and floor. This is normal and does not adversely affect
