| PROBLEM | REMEDY |
| You cannot find details for the amount of food prepared | Look for a similar food. Increase or shorten the length of the cooking times according to the following rule: Double the amount = almost double the time, Half the amount = half the time |
| The food got too dry | Set shorter cooking time or select lower microwave power. |
| The food is not defrosted, hot or cooked after the time came to an end. | Set longer cooking time or set higher power. Note that large dishes need longer time. |
| After the cooking time comes to an end, the food is overheated at the edge but is still not ready in the middle | Next time set a lower power and a longer time. Stir liquids halfway through, eg. soup. |
To get better results for rice use a flat, wide dish.
Defrosting
Always defrost roast with the fat side down. Do not defrost covered meat because this may cause cooking instead of defrosting. Always defrost whole poultry breast side down.
Cooking
Always remove chilled meat and poultry from the refrigerator at least 30 minutes before cooking. Let the meat, poultry, fish and vegetables stay covered after cooking.
Brush a little oil or melted butter over the fish. Add 30- ml of cold water for every 250g of vegetables. Cut the fresh vegetables into even size pieces before cooking.
Cook all vegetables with a cover on the container.
Reheating
When you reheat packed ready meals always follow the instructions written on the packaging.
Grilling
Grill flat food items in the middle of the grill rack. Turn the food over halfway through the set time and continue grilling.
Convection Cooking
You can cook food as in a traditional oven. No microwaves are used.
Combi Cooking
Use the Combi Cooking to keep the crispness of certain foods. At the half of the cooking time, turn over the foods then continue. Each mode combines the microwave, grill and convection functions at different time periods and power levels.
WARNING Refer to the safety chapters.
