Two glass bowls: one with a spoon inside, the other with a black 'X' symbol (no text or labels)• Take care when heating liquids!
When liquids (water, coffee, tea, milk, etc.) are nearly at boiling point inside the oven and are taken out suddenly, they may spurt out of their containers.
DANGER OF INJURIES AND BURNS!
To avoid that type of situation when heating liquids, put a teaspoon or glass rod inside the container.
- The contents of feeding bottles and baby food jars shall be stirred or shaken and the temperature checked before consumption, in order to avoid burns.
- Eggs in their shell and whole hard-boiled eggs should not be heated in the appliance since they may explode, even after microwave heating has ended.
- Warning! Do not heat pure alcohol or alcoholic drinks in the microwave. FIRE RISK!
- Beware! To avoid food overheating or burning it is very important not to select long time periods or power levels that
are too high when heating small quantities of food. For example, a bread roll can burn after 3 minutes if the power selected is too high.
- For toasting, use just the grilling function and watch the oven all the time. It you use a combined function to toast bread it will catch fire in a very short time.
- To achieve the best results when warming up small loads (such as a glass of water, a milk mug or a popcorn bag) it is suggested that they are placed in the following way:
- Insert the glass tray or the rectangular rack on the highest possible level, considering the dimensions of the food or drink to be heated;
- Place the food or drink on the left side of the glass tray or the rectangular rack.
- The popcorn bags cannot be placed directly over the rack; place the popcorn bag on a glass or ceramic dish and then place the dish on the left side of the rectangular rack.
- Turn or stir the food at regular intervals to improve heating uniformity.
- To achieve the best cooking results with microwaves, place the food on the rack or on the glass tray and insert them on the highest possible level.
- Do not place the food directly over the bottom of the oven cavity. The heating performance will be poor and there is the risk of damaging the oven.
- Do not cover the bottom of the oven cavity with aluminium or tin foil sheets as there is the risk of damaging the oven.
Avoid damaging the Microwave oven or other dangerous situations by following these instructions
- Never switch on the microwave when it is empty. If there is no food inside there may be an electrical overcharge and the oven could be damaged. RISK OF DAMAGE!
- For carrying out oven programming tests put a glass of water inside the oven. The water will absorb the microwaves and the oven will not be damaged.
- Do not cover or obstruct the ventilation openings.
- Place correctly the oven accessories on the side racks (see the section “Accessories”.)
- Use only dishes suitable for microwaves. Before using dishes and containers in the microwave, check that these are suitable (see the section on types of dishes).
- Never remove the mica cover on the ceiling of the oven interior! This cover stops fat and pieces of food damaging the microwave generator.
- Do not keep any inflammable object inside the oven as it may burn if the oven is switched on.
- Do not use the oven as a pantry.
- Do not use the oven for frying as it is impossible to control the temperature of oil heated by microwaves.
- Do not lean or sit on the open oven door. This may damage the oven, especially in the hinge zone. The door can bear a maximum weight of 8 kg.
- The base and the grills can bear a maximum load of 8 kg. To avoid damaging the oven, do not exceed this load.
- Failure to secure tightly the support with the nuts may lead to overheating and damages.

Between two rails of the side supports or on any of the extractable runners, if the oven has them.
-
The rack and some of the trays have retention grooves to prevent them from accidentally being removed. Place these grooves towards the back of the oven, facing upwards Figure 4.
-
The surface of the rack on which the container will rest must be below the side rails. This prevents the container from accidentally sliding. Figure 5.
Cleaning and maintenance

WARNING
Disconnect the appliance from the mains power supply before any operation.
CLEANING THE OVEN EXTERIOR AND OVEN ACCESSORIES
Clean the outside of the oven and accessories with warm soapy water or with a mild detergent.
Take great care when cleaning stainless steel or painted surfaces. Use only sponges or cloths that do not scratch.
CLEANING THE OVEN INTERIOR
Clean the oven interior regularly to remove traces of fat or food, which can later give off smoke and odors and cause stains to appear. Use nylon brushes or sponges with warm soapy water to clean enameled surfaces such as the bottom of the oven. Clean when the oven is cold. Use oven cleaning products only on enameled surfaces and always follow the manufacturer's instructions.

WARNING
Do not clean the oven interior with steam or pressurized-water cleaning equipment.
Do not use metal scouring pads, wire brushes or any utensil that can scratch the enamel.
Over time, certain types of food such as tomatoes, vinegar and salt-baked dishes may cause the enamel to change color. This is normal and does not affect the functioning of the oven. Do not try to remove these stains using aggressive methods such as those described, as this could cause permanent damage to the surface.
Clean the oven seal regularly to eliminate all traces of fat or food. This will prevent the seal from becoming damaged and breaking during subsequent cooking operations.
It is advisable to clean this seal without removing it.

-
Reattach the top seal of the door, making sure that the side tabs fit into their housings.

WARNING
Never switch the oven on if any of the glass panes on the door are missing.
STEAM OVEN SPECIFIC CLEANING
Descaling
Whenever steam is produced, irrespective of the hardness of the local water supply (i.e. the limescale content of the water), limescale is deposited inside the steam generator.
The time interval between descaling depends on the hardness of the water and frequency of use. If steaming 4×30 minutes per week, the appliance must be descaled (depending on water hardness) roughly as follows:
| Water hardness | Descale after about |
| Very soft | 18 months |
| Medium | 9 months |
| Very hard | 6 months |
The appliance automatically detects when descaling is necessary as described on the user's guide booklet.
IMPORTANT NOTE: Failure to descale the appliance will likely impair the functioning of or cause damage to the appliance.
Suitable descaling solutions
For descaling, use the descaling solution "durgol®".
This solution allows a professional and careful descaling of your appliance. Available at Customer Care Centers.
Warning! Do not use vinegar or vinegar-based products as they can cause damage to the oven's internal circuit.
Traditional descaling solutions are not appropriate because they can contain foaming agents.
CHANGING THE OVEN LIGHT BULB
