How to wash a Liebherr refrigerator: complete instructions with nuances for all models

Refrigerators Liebherr are famous for their German reliability and innovative storage systems, but even they require regular maintenance. Improper cleaning can damage antibacterial coatings, disrupt operation NoFrost or BioFresh, and also lead to the appearance of persistent odors. This article contains a step-by-step washing algorithm taking into account the features of different series Liebherr, from budget Comfort to premium PremiumPlus.

We will look at what products are safe for internal surfaces, how to properly defrost models with SmartFrost, and why you should never use abrasive sponges on zone BioFresh.

Preparation: what needs to be done before washing

The first step is to disconnect the refrigerator from the network. For models Liebherr with electronic control (for example, series CS or BS) after switching off, the error indicator E1 may light up - this is normal and does not require a reset. Just wait until the defrosting cycle is completed.

If your refrigerator is equipped with a system NoFrost, just remove the food and leave the door open for 1-2 hours. For models with SmartFrost (for example, Liebherr CNef 4315) or a drip defrosting system, complete defrosting will be required - this will take 3-5 hours depending on the thickness of the ice.

• 🔌 Unplug food —unplug the plug from the outlet, do not rely on the off button.
• 🥬 Get all the products - put them in a cooler bag or wrap them in towels if it’s cold outside.
• 📦 Remove all removable elements: shelves, containers BioFresh, bottle racks, vegetable drawers.
• 🧊 Prepare water containers —a tray for collecting melt water (included with the refrigerator) or towels.

⚠️ Attention: If your model has a function SuperCool or SuperFrost, it should be turned off 12 hours before washing. Otherwise, the compressor may overheat when turned on again.

How can you wash a Liebherr refrigerator: safe products

The manufacturer categorically does not recommend the use of aggressive chemicals (for example, Domestos or Whiteness), as they destroy the antibacterial coating BioCooling and can damage door seals. Optimal options:

For the zone BioFresh (if your model has it), use only soft products without alcohol and chlorine. The manufacturer recommends Liebherr BioFresh Cleaner, but a soda solution is also suitable. Do not rub this area with hard sponges - its surface has micropores to regulate humidity.

1. Door seals - they must be washed separately with warm water and soap, then wiped dry. In models Liebherr the seals have a magnetic insert, therefore, do not pull them too hard.
2. Ventilation holes (in systems NoFrost) - clean them with a cotton swab soaked in alcohol. Clogged holes increase energy consumption by 25-30%.
3. Drainage hole —in refrigerators with a drip system it is located at the back (usually under the bottom shelf). Clean it with a special brush or tube from the kit.

For washing the back wall (where it is located evaporator) use a soft sponge. In models with SmartFrost the back wall may be covered with frost - do not remove it with a knife! Wait until it is completely thawed.

How to wash a Liebherr refrigerator with the NoFrost system

In refrigerators with NoFrost (for example, Liebherr CN 4015 or Liebherr BSes 4366) ice does not form on the walls, but this does not mean that they do not need to be cleaned. Key nuances:

• 🌀 Fan - located on the back wall Its blades can only be cleaned. with a soft brush or vacuum cleaner at minimum power. Do not allow water to enter!
• ❄️ Evaporator - hidden behind the panel. It does not need to be washed manually: the system defrosts itself every 8-12 hours.

If ice appears in the refrigerator, this is a sign of a malfunction. The most common culprit is: NoFrost ice appears, this is a sign of a malfunction. Most often to blame:

• Clogged drainage (needs to be cleaned). tube).
• Broken evaporator heater (needs replacement).
• Faulty defrost sensor (error E2 on the display).

What to do if NoFrost stops working?

If the refrigerator Liebherr s NoFrost started to become overgrown with ice, first check:

1. Does the door close tightly (place a sheet of paper - if it falls out, the seal needs to be replaced).

2. Are the shelves overloaded (air circulation should be free).

3. Are there any errors on the display (codes E2, E3 or E4 indicate problems with defrosting).

If everything is in order, but the ice continues to build up, call a technician to diagnose the electronic unit.

Elimination of odors: 5 tested methods

Even after thorough washing in the refrigerator Liebherr a persistent odor may remain. Reasons:

• Bacteria in the drainage hole (especially if it has not been cleaned for a long time).
• Mold on the seal (often occurs in models with BioFresh due to high humidity).
• Food residues in hard-to-reach places (for example, under drawers for vegetables).

Effective methods of elimination:

1. Activated carbon — place 5-6 tablets in a small container on the middle shelf. Change every 2 weeks.
2. Coffee beans —2-3 tbsp. spoons in an open jar will absorb odors in 12 hours.
3. Lemon peel —wipe all surfaces with juice, then put the peels on the shelf for a day.
4. Special absorbers (for example, Liebherr FreshAir) - work up to 3 months.
5. Ultraviolet lamp - suitable for models with the function UV-Clean (for example, Liebherr SIGN 3576). Turn on the mode for 20 minutes.

⚠️ Attention: Do not use fragrances with a strong odor (for example, vanilla or lavender) - they can be absorbed into the plastic and mixed with the odors of the products. The best option is neutral absorbers.

If the smell remains after all the procedures, check:

• 🧀 Sour milk or cheeses in closed containers - their smell can leak out.
• 🥩 Meat products - even in vacuum packaging they can "leak".
• 🍎 Rotten fruit in the drawer BioFresh —their smell is difficult to remove.

• 🧴 Glass cleaner — suitable for glossy models (for example, Liebherr SIGN 3576).
• 🧼 Soap solution —for matte surfaces and handles.
• 🧽 Microfiber cloth — required for coated models CleanSteel or SmartSteel.

Clean the handles (especially in models with touch controls, for example Liebherr BSes 4366) with a damp cloth without alcohol. To remove greasy fingerprints, use a vinegar solution. (1:3 with water).

If there are stains on the case from magnets or stickers, do not rub them with your nails - use a plastic scraper or credit card, after moistening the stain with warm water.

1. Using hot water - from a sudden temperature change. crack glass shelves (especially in models Liebherr CNef).
2. Washing a switched-on refrigerator - this is not only dangerous, but can also cause a short circuit in the electronic unit.
3. Use of chlorine-containing products - they destroy the antibacterial coating and seals.
4. Ignoring the drainage hole — clogged drainage leads to accumulation of water under vegetable boxes.
5. Blow-drying —hot air can deform plastic parts.

Another common mistake is incorrect assembly after washing. For example, if you place the shelves not in the grooves, this can disrupt the air circulation in the systems NoFrost or SmartFrost. that:

• The back wall of the shelf fits tightly against the stop.
• Drawers BioFresh are installed until they click.
• Door compartments are not are skewed (otherwise the door will not close tightly).

FAQ: answers. for frequently asked questions
