Miele M 8260-2 manual Testing dishes for their suitability, Disposable containers

Disposable containers, such as trays made from polystyrene, can only be used for very short, timed warming and reheating of food.

Plastic boiling bags can be used for cooking and reheating. They should be pierced beforehand so that steam can escape. This prevents a build-up of pressure and reduces the risk of the bag bursting.

Do not use metal clips, plastic clips containing metal parts, or paper ties containing wire. There is a danger that they will ignite when heated. Fire hazard.

Disposable containers

Only those plastic disposable containers which are specified by the manufacturer as suitable for use in a microwave oven may be used.

Do not leave the oven unattended when reheating or cooking food in disposable containers made of plastic, paper or other inflammable materials.

Disposable containers are not always recyclable or bio degradable.

Testing dishes for their suitability

If in doubt as to whether glass, earthenware or porcelain plates or dishes are suitable for use in a microwave oven, a simple test can be performed:

^Place the item you wish to test in the centre of the oven, fill a suitable glass with water and also place this in the oven.

^Close the door.

^Turn the power selector to 900 W.

^Enter a time of 30 seconds with the time selector.

^Press the Start button.

At the end of the test, the water in the glass should be warm and the dish cool. If the dish is hot and the water cold, it would be unwise to use the dish.

If a crackling noise is heard accompanied by sparks during the test, switch the appliance off imme- diately (press button Stop/C twice).

Any crockery which causes this reaction is unsuitable for use with microwave power.

If any doubt exists about the suitability of containers, please contact the supplier.

This test cannot be used to check whether items with hollow knobs or handles are suitable for use with microwave power.
