Warning and Safety instructions

Technical safety

Unauthorised installation, maintenance and repairs can cause
considerable danger for the user. Installation, maintenance and re­pairs must only be carried out by a Miele authorised technician.
Radiation by microwaves:
Service or repairs which necessitate the removal of any casing must only be carried out by a suitably trained service technician.
Never use a damaged steam oven. It could be dangerous. Check
it for visible signs of damage before using it.
Check the door and door seal for any sign of damage. If any dam-
age is noticed, the oven should not be used again in Microwave mode until the fault has been rectified by a service technician.
Operating a damaged appliance can result in microwave leakage
and present a hazard to the user. Do not use the appliance if:
– the door is warped, – the front of the oven compartment is dented or bowed, – the door hinges are loose, – holes or cracks are visible in the casing, the door or the oven in-
terior walls.
– there is moisture between the door panes.
Reliable and safe operation of this steam oven can only be as-
sured if it has been connected to the mains electricity supply.
The electrical safety of this appliance can only be guaranteed
when correctly earthed. It is essential that this standard safety re­quirement is met. If in any doubt please have the electrical installa­tion tested by a qualified electrician.
10
Warning and Safety instructions
Before connecting the appliance to the mains supply, ensure that
the connection data on the data plate (voltage and frequency) match the mains electricity supply. This data must correspond in order to avoid the risk of damage to the appliance. Consult a qualified electrician if in any doubt.
Do not connect the steam oven to the mains electricity supply by
a multi-socket adapter or an extension lead. These do not guarantee the required safety of the appliance (fire hazard).
For safety reasons, this steam oven may only be used when it has
been built in. This is necessary to ensure that all electrical compon­ents are shielded.
This steam oven must not be used in a non-stationary location
(e.g. on a ship).
Never open the casing of the appliance. Tampering with electrical
connections or components and mechanical parts is highly danger­ous to the user and can cause operational faults.
While the appliance is under guarantee, repairs should only be un-
dertaken by a Miele authorised service technician. Otherwise the guarantee is invalidated.
Miele can only guarantee the safety of the appliance when genu-
ine original Miele replacement parts are used. Faulty components must only be replaced by Miele spare parts.
If the plug is removed from the connection cable or if the cable is
supplied without a plug, the appliance must be connected to the electrical supply by a suitably qualified electrician.
If the connection cable is damaged, it must be replaced by a suit-
ably qualified electrician with a special connection cable of type H 05 VV-F (pvc insulated). See "Electrical connection".
During installation, maintenance and repair work, the appliance
must be disconnected from the mains electricity supply.
11
Warning and Safety instructions
If the steam oven is installed behind a furniture panel (e.g. a door),
ensure that the door is never closed whilst the steam oven is in use. Heat and moisture can build up behind a closed furniture panel and cause subsequent damage to the steam oven, the housing unit and the floor. Do not close the door until the steam oven has cooled down completely.
12
Warning and Safety instructions

Correct use

Danger of burning. The steam oven becomes hot when in use.
You could burn yourself on the heating elements, oven interior, cooked food, oven accessories or hot steam. Wear oven gloves when placing food in the oven or removing it and when adjusting oven shelves etc. in a hot oven. Take care when putting cooking containers into the oven or removing them not to spill the contents.
Danger of burning. There will be some residual hot water in the
steam generator at the end of a cooking process. This will be pumped back into the water container. Take care not to spill the con­tents when taking the water container out of the appliance.
Do not use the steam oven to heat up or bottle food in sealed jars
and tins. Pressure will build up inside them and they can explode causing damage to the appliance, as well as the risk of injury and scalding.
Plastic dishes which are not heat- and steam resistant melt at high
temperatures and can damage the appliance. Use temperature- (to 100°C) and steam-resistant plastic dishes for steam cooking. Follow the manufacturer's instructions.
Food which is left in the oven to be kept hot can dry out and the
moisture released can lead to corrosion damage in the appliance. Do not use the steam oven for keeping food warm and do not use utensils in the appliance which could corrode.
You could injure yourself on the open steam oven door or trip over
it. Avoid leaving the door open unnecessarily.
The door can support a maximum weight of 8kg. Do not sit on or
lean against an open door, and do not place heavy objects on it. Also make sure that nothing can get trapped between the door and the oven cavity. The steam oven could get damaged.
13
Warning and Safety instructions
When using a small electrical appliance, e.g. a hand-held blender,
near the steam oven, care should be taken that the cable of the ap­pliance cannot get trapped by the steam oven door. The insulation on the cable could become damaged, giving rise to an electric shock hazard.
Microwave function
Please be aware that durations when using microwave power are
often considerably shorter when cooking, reheating and defrosting than when using functions without microwave power. Excessively long cooking times can lead to food drying out and burning or could even cause it to catch fire.
The Microwave function can be used for heating food and
drinks. Do not use the Microwave function for drying flowers, herbs, bread, rolls or other flammable materials which could catch fire and cause injury by burning.
Always cover food when using Microwave mode . It is important that the heat is allowed to spread evenly through-
out the food being cooked and that it is hot enough. This can be achieved by stirring and/or turning the food, and ob­serving a sufficiently long standing time, which should be added to the time needed for cooking, reheating or defrosting.
When heating food and drinks, remember that the heat is created
in the food itself, and that the container will normally be cooler. The dish is only warmed by the heat of the food. Before serving, remember to allow a sufficient standing time and then always check the temperature of the food after taking it out of the steam oven. The temperature of the container is not an indication of the temperature of the food or liquid in it. This is particularly im-
portant when preparing food for babies, children, and the elderly or infirm. Shake or stir baby milk and food thoroughly after heating,
and try it for temperature to ensure that it will not scald the baby.
14
Warning and Safety instructions
Microwave mode is not suitable for cleaning or disinfecting
items. Items can get extremely hot and there is a danger of burning when the item is removed from the appliance.
Do not cook or reheat food or liquids in sealed containers, jars or
bottles. With baby bottles, the screw cap and teat must be removed. Otherwise pressure will build up which can cause the bottle or con­tainer to explode, posing a severe risk of injury.
When heating up liquids, always place a suitable glass rod or
utensil into the cup or glass. When boiling and in particular when heating up liquids using microwave power, the boiling point of the li­quid may be reached without the production of typical bubbles. The liquid does not boil evenly throughout. This so-called 'boiling delay' can cause a sudden build up of bubbles when the container is re­moved from the oven or shaken. This can lead to the liquid boiling over suddenly and explosively. The formation of bubbles can be so strong that the pressure forces the oven door open. Stir liquid before it heats up or boils. Once it has heated up wait for a minimum of 20seconds before removing the container from the mi­crowave oven.
Eggs can be cooked without their shells using microwave power
only if the yolk membrane has been punctured several times first. The pressure could otherwise cause the egg yolk to explode.
Eggs in their shells will explode if cooked with microwave power,
even after taking them out of the oven. They can only be cooked in their shells using the steam cooking function or in an appropriate automatic programme. Hard-boiled eggs must not be reheated with microwave power either as they too will explode.
Food with a thick skin or peel, such as tomatoes, sausages, jacket
potatoes and aubergines, should be pierced or cut in several places to allow steam to escape and prevent the food from bursting.
15
Warning and Safety instructions
Do not use the microwave function to heat up cushions or
pads filled with cherry kernels, wheat grain, lavender or gel, such as those used in aromatherapy. These pads can ignite when heated even after they have been removed from the oven.
To avoid fuelling any flames, do not open the oven door if smoke
occurs inside the appliance. Interrupt the process by switching the appliance off and disconnect it from the mains electricity supply. Do not open the door until the smoke has dispersed.
Dishes with hollow knobs or handles are not suitable for use with
microwave power. Moisture which has gathered in the hollow re­cesses can cause pressure to build up and the item can explode. If the hollow recess is sufficiently ventilated, the item could be used. However, we recommend that you do not use such dishes in Mi­crowave mode.
Fire hazard. Using microwave power with plastic dishes which are
not microwave safe can cause them to melt and damage the appli­ance. Do not use any containers or cutlery made from or containing metal, aluminium foil, lead crystal glassware, temperature-sensitive plastics, wooden utensils or cutlery, metal clips or plastic or paper covered wire ties. Do not use bowls with milled rims, or plastic pots with the foil lid only partially removed (see "Suitable containers for microwave use).
Do not leave the steam oven unattended when heating or cooking
food in disposable containers made of plastic, paper or other inflam­mable materials using the Microwave function. Before using single-use containers make sure they are suitable for microwave use. See "Suitable containers for microwave use ­Plastics".
Do not heat food in the steam oven in heat-retaining bags which
are intended for use in normal ovens. These heat-retaining bags usually contain a thin layer of aluminium foil which reflects microwaves. This reflected energy can, in turn, cause the outer paper covering to become so hot that it ignites.
16
Warning and Safety instructions
The steam oven can suffer damage when using Microwave func-
tion if it is empty or incorrectly loaded. For this reason please do not use the Microwave function to pre-heat crockery or to dry herbs and do not start the Microwave function when the steam oven is empty.
17
Warning and Safety instructions

Description of functions

Steam cooking mode

Water container

The maximum water level is 1.5 litres, the minimum 0.5 litres. These levels are indicated on the container. Do not ex­ceed the maximum level.
The amount of water used will depend on the type of food and the duration of cooking. Water will sometimes need to be replenished during the cooking pro­gramme. Water consumption is in­creased if the door is opened during cooking.
At the end of the cooking programme hot residual water in the steam gener­ator is pumped back into the water con­tainer. The water container must be emptied after each use.
The water container is removed using a push/pull system: push gently on the water container to remove it.

Temperature

Some functions have a default recom­mended temperature. This temperature can be altered for the programme in use, or for every time that programme is used (see "Settings - Recommended temperatures").

Noises

You will hear a pumping sound when the appliance is switched on, during use and after switching it off. This is the sound of water being pumped through the system and is quite normal.
When the steam oven is in use, you will hear a fan noise.

Heating-up phase

During the heating-up phase the display will show the temperature in the cook­ing compartment as it rises and Heating-
up phase in all programmes except for Automatic progs., Menu cooking and Main­tenance.
When cooking with steam, the duration of the heating-up phase will depend on the quantity and the temperature of the food. In general the heating-up phase will last for approx. 5 minutes. The dur­ation will be longer if you are cooking refrigerated or frozen food.

Cooking phase

The cooking phase begins when the set temperature is reached. During the cooking phase, the duration remaining will be shown in the display.

Duration

You can set a duration between 1minute (0:01) and 10hours (10:00). If the duration exceeds 59minutes you have to enter it in hours and minutes. Example: duration 80minutes = 1:20.
27
Description of functions

Steam reduction

If a cooking temperature above approx. 80°C has been set, the appliance door will automatically open a fraction just before the end of a cooking programme to release some of the steam from the cabinet. Steam reduction will appear in the display. The door will then close again automatically.
Steam reduction can be switched off if you wish (see "Settings - Steam reduc­tion"). If switched off there will be a lot of steam emitted from the cabinet when the door is opened.

Microwave power

How it works

In the steam oven with microwave there is a high-frequency tube called a mag­netron. This converts electrical energy into microwaves. These microwaves are distributed evenly throughout the oven interior, and rebound off the metal sides of the oven interior to reach the food from all sides.
microwave energy, start to oscillate
2.5thousand million times a second. The friction caused by this vibration creates heat, which first starts develop­ing around the outside of the food and then slowly penetrates towards the centre. The moisture, fat and sugar content of food will affect the speed at which it is cooked. The heat is gener­ated in the food itself.

Advantages

Food can generally be cooked without adding much liquid or cooking oil.
Microwaves stop being produced as soon as the cooking process is inter­rupted or the appliance door is opened. When the appliance is in op­eration, the closed, sealed door pre­vents microwaves escaping from the appliance.
In order for microwaves to reach the food, they must be able to penetrate the cooking utensil being used. Microwaves can penetrate porcelain, glass, card­board and plastics, but not metal. Do not, therefore, use utensils made of metal, or which contain metal, for ex­ample in the form of gold or silver trim. The metal reflects the microwaves and this could cause sparking. The mi­crowaves cannot be absorbed.
Microwaves pass through a suitable container and find their way directly into the food. All food contains moisture molecules which, when subjected to

– Plastic microwave containers
– Plastic "Boil-in-the-bag" bags
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. There are also special steaming bags available which do not need to be pierced. Please follow instructions given on the packet.
– Roasting bags and tubes
Please follow the manufacturer's in­structions when using roasting bags and tubes.
