Fruit & Vegetable safe

Fruit & Vegetable safe

Crunchy salad and strawberries: the most delicate foods deserve a special place so they stay fresh longer – in BioFresh safes. In the Fruit & Vegetable safe the temperature is close to 0°C. Combined here with the constant humidity, thanks to the air-tight closure, unpackaged fruit and vegetables feel particularly at home. You do not have to adjust anything.

Meat & Dairy safe

Meat & Dairy safe

Do you want the tender veal fillet or fresh milk to stay fresh for as long as possible? The BioFresh safes will ensure this is the case. In the Meat & Dairy Safe, the temperature is close to 0 °C – ideal storage conditions for even the most delicate of foods. And best of all, everything is perfectly adjusted in the factory for immediate use – and for longer freshness.

Retrofitable SmartDeviceBox

Retrofitable SmartDeviceBox

Want to be prepared for the future of the Smart Home? Your Liebherr will be happy to help. You can retrofit it with a SmartDeviceBox which will connect your Liebherr to the Internet. The SmartDeviceBox can be installed in just a few steps and will open up the whole world of digital possibilities to you today.

LightTower

LightTower

Enjoy an optimally illuminated interior: the LightTower shows off the food in its best light and is positioned so that all of your filled fridge is illuminated at all times. The flush mounting of the LightTower in the side walls means there is also more space for your food.

Touch & Swipe display

Touch & Swipe display

Control of your Liebherr at your fingertips: thanks to the Touch & Swipe display, you can operate your refrigerator intuitively and with ease. Simply select functions such as SuperCool on the colour display by tapping and swiping. The temperature is controlled just as easily. And, what if you are not actively using the display? Well, it then shows you the actual temperature.

SmartSteel rear wall

SmartSteel rear wall

The rear wall in elegant SmartSteel gives your Liebherr a stylish look and feel. Your food will also love SmartSteel as stainless steel is food-safe and hygienic. SmartSteel also reduces the visibility of fingerprints – making the appearance even more pleasing.

SoftSystem

SoftSystem

From breakfast to a midnight snack – a fridge needs to be open and closed on many occasions. And your Liebherr makes this is a lot of fun. With the SoftSystem, your fridge door closes softly and safely, and in a way which is pleasantly quiet and light. Bottles stored in the inside door remain securely in place – nothing rattles or wobbles.

SoftTelescopic

SoftTelescopic

Look forward to opening your BioFresh safes. And this is not just because of the fresh food – but also because opening is so easy, and closing is automatic and cushioned. The telescopic rails slide the safe gently towards you. And because these extend fully, you have the best overview of the contents.

Space for baking tray 

Space for baking tray 

Do you want to keep that home-baked fruit pie fresh? Or maybe a prepared pizza to be baked later on? If so, simply slide your baking tray into your Liebherr ¬- it has plenty of space for storing a baking tray. Really convenient – you can slide the baking tray in and out when the door is opened at 90°.

PowerCooling system

PowerCooling system

Do you want to be sure that the cold is distributed as evenly as possible in your refrigerator? If so, the PowerCooling system is what you need. The fan – as powerful as it is quiet – distributes the cold air efficiently throughout the entire refrigeration compartment.

LED BioFresh lighting

LED BioFresh lighting

Experience the pleasure of brightly lit fresh fruit and vegetables. The LED BioFresh lighting shows off the contents of your BioFresh safe in its best light. The lighting is positioned centrally above the BioFresh safes and supplemented by LED light columns on both sides. These extend into the topmost BioFresh safe ensuring bright illumination.

VarioSafe

VarioSafe

Do you want a clearly arranged place for small food items such as yoghurt pots, jam jars or tubes? Your Liebherr provides this with the VarioSafe. It not only creates order, but is also highly adaptable. Simply place the two-stage height-adjustable VarioSafe in the refrigerator where it suits you best.

Door shelf

Door shelf

Do you want a safe storage area for your drinks or food? And do you still want to reach them easily? Our door shelves offer you both. They are height-adjustable and therefore meet all your requirements. The sliding and removable bottle holder is also convenient. This holds your bottles securely at all times.

Separable glass shelf

Separable glass shelf

If you store a carafe or tall container in the refrigerator, you don't want to have to remove an entire glass shelf. And why should you? Because there are separable glass shelves. Simply slide the front half of the glass shelf under the back half. This allows you to place higher containers at the front and still have enough space for other food.

Convenient height adjustment for glass shelves

Convenient height adjustment for glass shelves

Do you need a large container to go in the fridge? If so, simply adjust the heights at which you insert the glass shelves. The convenient height adjustment means this can be done quickly and individually – even with food stored on the shelves.

Language settings

Language settings

From now on, you and your Liebherr will always get along fine – because it speaks your language. The variable language setting makes this possible. When you start up the appliance, simply select from twelve languages on the display – and operate your Liebherr in the language of your choice.

EnergySaver

EnergySaver

Do you want to save energy and money at the same time? Your Liebherr will help you do just that – with the energy-saving mode. When you activate the EnergySaver, the standard temperature increases by two degrees. This means your Liebherr needs even less power – and your food stays optimally fresh.

Display lock

Display lock

An illuminated display is a magnet for children's hands – your Liebherr also knows that. That's why there is the display lock. It ensures the settings on your refrigerator are not changed unintentionally. You can also, of course, simply deactivate the display lock.

Power failure alarm

Power failure alarm

Your Liebherr is a real guardian angel for your food. In the event of a power failure, it reliably sounds the alarm. Not only do you hear the alarm, but you can also see it. The display shows the highest temperature reached in the freezing compartment. However, you are never alerted unnecessarily. If there is no critical rise in temperature during a brief power failure, the alarm will not go off.

HolidayMode

HolidayMode

Are you going away? Then why not send your Liebherr on holiday too? In HolidayMode, the fan and SuperCool are switched off and your refrigerator regulates its temperature to +15 °C. This saves electricity but still prevents unpleasant odours. The freezer compartment, of course, remains switched on.

SuperCool

SuperCool

You want your fridge to maintain the optimum temperature, even if you have just put shopping in from the market which has been warmed by the sun? This is a case for SuperCool. Once activated, your Liebherr boosts its performance until the fresh food is as cool as the rest of the contents. SuperCool then switches off automatically – after 12 hours at the latest.

Door alarm

Door alarm

The door alarm of your Liebherr makes sure that you don’t unnecessarily use energy and that food doesn’t go off: if the appliance door stays open for too long an alarm goes off – flashing light and a warning tone. You decide what “too long” means: depending on the settings the door alarm comes on after one, two or three minutes.

SabbathMode

SabbathMode

On the Sabbath, all activities are at rest – this also applies to electrical appliances. Your Liebherr takes this into account. In SabbathMode, all lighting and displays are switched off and there are no noises generated by actions, e.g. alarms. After 80 hours, the SabbathMode deactivates.

VarioBoxes

VarioBoxes

Where did I put that little packet of yeast? And where's the tube of mustard? To easily find the small items in the fridge, there are the VarioBoxes. They keep everything clearly arranged and organised in the inside door. Their transparent design means you immediately see what's inside. The boxes are easy to remove – and thanks to the pull-out stop, nothing will fall to the floor- guaranteed.

Butter dish

Butter dish

You can also expect a lot of your butter dish. The butter dish should be timelessly beautiful and fit perfectly into the refrigerator's inside door. Through the transparent lid you can see how much butter is left at all times. The dishwasher-safe lid and base section also interlock so securely that you can carry the dish holding the lid with one hand.

Replaceable door seal 

Replaceable door seal 

Do you think the door seal on your Liebherr needs to be replaced after a few years? This is very easy to do yourself. The replaceable door seal can be removed in a few simple steps – and the new seal is just as easy to insert. As a result, this part of the refrigerator is always spotless and hygienically clean.

"Door hinge change, integrated freezer compartment "

Do you want to avoid spending time changing the door hinge of the freezer compartment when installing your Liebherr in the furniture niche? The slider control means this can be done in seconds and without any manual skills. Simply slide the slider on the freezer compartment from right to left – that's it, done! This saves you a lot of time.

Dishwasher-safe features

Dishwasher-safe features

The features of your Liebherr are practical in two ways: Not only do they simplify everyday use, they are also very easy to clean. Does the butter dish, FlexSystem or ice cube tray need to be cleaned? Just put them in the dishwasher. Then you’ll have more time for other things.
