Features

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.

Touch display

Touch display

Fingertip control: the touch display enables easy and intuitive operation of your Liebherr. All functions are clearly arranged on the display. By gently tapping a finger, for example, you can easily select the functions or check the current temperature of your refrigerator.

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°.

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.

SuperSilent

SuperSilent

Shhh – listen carefully. Your Liebherr is so quiet that you have to strain your ears to hear it. How is this achieved? All refrigeration components such as compressors, valves, fans and evaporators are optimised and perfectly adapted to one another. This means you only hear what you want to hear in your kitchen.

LED side lighting on both sides

LED side lighting on both sides

For a quick overview of everything in the refrigerator: thanks to the LED side lighting on both sides, your food is in view at all times. The LEDs are positioned so that your large refrigerator is also illuminated with food inside it. And the LEDs integrated flush into the side walls mean that the valuable usable area is fully maintained.

CleaningMode

CleaningMode

Until now, you had to make a decision when cleaning the refrigerator: do I switch it off to save energy, or leave it switched on so I can see? The CleaningMode removes this dilemma. The refrigeration switches off while the lights stay on. This means you can stay totally relaxed while cleaning your Liebherr.

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.

PartyMode

PartyMode

Now your ready for the guests to come – because your Liebherr is also in a party mood. As soon as you switch on PartyMode, it reliably provides ice-cold drinks and an extra portion of ice cubes. PartyMode activates functions such as SuperCool and maximum ice production. After 24 hours, your Liebherr automatically returns to its normal mode.

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

Your Liebherr's door alarm ensures that you don't use up energy unnecessarily and spoil food. The moment the fridge door is left open for too long, it alerts you – with a pulsating light and a warning tone. However, you decide how long is “too long”. Depending on the setting, the door alarm is triggered after 1, 2 or 3 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 the fridge lighting is switched off, as are all sounds, noises and the display. After 80 hours, the SabbathMode deactivates.

FreshAir activated charcoal filter

FreshAir activated charcoal filter

The smell of some foods is sometimes less pleasant. However, this is no problem for your Liebherr. Thanks to FreshAir activated carbon filters, there is always fresh air in the interior. The filter is located right on the air flow in the fan housing and neutralises odours as far as possible. The display reminds you to change the filter.

Egg tray

Egg tray

Do you want to store eggs in your refrigerator safely and without a box? This is no problem with the egg tray. This will store up to 10 chicken eggs, keeping them stable and protected, and well cooled. The tray fits both in the inside door and on the glass shelves.

Drawer

Drawer

Convenient to pull out and push in: the drawer has plenty of extra space. And when you pull it out, it slides out gently, as it rests on telescopic rails. The drawer slides back in just as gently and quietly.

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.
