Refrigerators Liebherr are known for their reliability and thoughtful ergonomics, but even the most advanced models sometimes need to remove the internal drawers - for general cleaning, replacement or repair. At first glance, the task seems simple, but incorrect actions can lead to broken guides, cracks in the plastic, or even damage to the system BioFreshif we are talking about premium series. Particular care must be taken when handling drawers in models with NoFrost automatic defrostingwhere the design may differ from classic refrigerators.
In this article we will look at universal dismantling methods for all types of drawers Liebherr - from standard plastic containers to specialized compartments for vegetables and meat. You will learn how to avoid common mistakes (for example, trying to pull out a drawer by force without disengaging the latches), what tools you may need, and what to do if the structure is “jammed.” We will pay special attention to models with electronic controlwhere incorrect removal can disrupt the settings of temperature zones.
If your refrigerator Liebherr is equipped with a system SmartDevice (control via application), before dismantling the drawers We recommend disabling the option Automatic humidity control in the menu. This will prevent false alarms of the sensors during re-installation.
1. Preparation: what to do before removing the box
The first step is to ensure safety for both the equipment and yourself. Start by disconnecting the refrigerator from the network if complex dismantling is ahead (for example, in models with built-in humidity sensors). For simple drawers in the freezer, it is enough to transfer the food to another compartment or thermal bag.
Be sure to prepare the work space:
- 🧴 Soft cloth or towel - place it under the drawer so as not to scratch the floor or door if accidentally dropped.
- 🔧 Plastic spatula or spatula - useful for carefully prying up the fasteners (especially in models Liebherr CNef 4815 and similar ones).
- 📸 Smartphone - take a photo of the location of the drawers and guides if you are afraid mix up when reassembling.
- 🧤 Rubber gloves —will protect hands from sharp edges of plastic and cold (relevant for freezers).
In models with NoFrost system front By removing the boxes, check whether they are blocked ventilation grill. In the series Liebherr GP it is often secured with latches that can be accidentally broken. If the drawer “does not fit”, do not pull it by force - first inspect the back wall for hidden fasteners.
2. Universal method: how to remove a standard plastic box
Most models Liebherr (for example, CBPesf 4856 or CUag 3311) are equipped with drawers on telescopic guides. To remove them:
- Pull out the drawer completely until it stops.
- Lift its front part by 2-3 cm - you should hear a click (this is the latch that has come out of the groove).
- Gently pull the drawer towards you, holding it in a raised position.
If the box does not lift, check for presence locking clips on the sides. In some series (for example Liebherr ICBN 3366) they are hidden under rubber seals. Pry them up with a plastic spatula without using excessive force.
Extended all the way|Front raised 2-3 cm|No locking products in rear|SuperCool/SuperFrost functions disabled (if equipped)-->
In models with the BioFresh system, the drawers have additional rubber seals. They cannot be pulled by the edges - only by the central handle, otherwise the elastic band will be deformed and lose its tightness.
3. Features of dismantling in refrigerators with the NoFrost system
In refrigerators Liebherr with NoFrost (for example, GPesf 3666 or ICBN 3366) drawers are often attached to ventilation system. It is important here not to confuse the guides with air ducts. Algorithm of actions:
1. Unplug the refrigerator and wait until the fan stops (usually takes 1-2 minutes).
2. Pull the drawer out to the maximum and look under it - in models with NoFrost there may be protective grillethere, which needs to be removed first.
3. Press the latches on the sides (they may be hidden under plastic plugs) and pull the drawer up.
If the drawer is “jammed,” do not try to tear it out. In the series Liebherr Premium NoFrost guides are sometimes blocked due to icing of the rear wall. In this case:
- 🔥 Defrost the refrigerator for 3-4 hours (do not use a hairdryer or hot water!).
- ❄️ Check that ice has not gotten into the grooves of the guides.
- 🔧 If the problem persists, it may be faulty defrost heater —diagnostics required.
What to do if the drawer cannot be removed even after defrosting?
In this case, the problem may be deformation of the guides (for example, due to overloading of the drawer). Inspect them for cracks or bending. If the guides are intact, try lubricating them food grade silicone spray (do not use WD-40!). In extreme cases, it may be necessary to replace the guides - their part numbers are indicated in the instructions for the model.
4. BioFresh boxes: how not to damage the humidity control system
Compartments BioFresh in refrigerators Liebherr (series CBNesf, CBPesf) are equipped with humidity sensors i special seals. Their dismantling requires special care:
1. Disable the function BioFresh in the refrigerator menu (if it is active).
2. Remove front panel the drawer - it is attached to latches that need to be carefully pressed out with a screwdriver.
3. Pull the drawer out all the way and press on red latches on the sides (in some models they are green).
⚠️
Attention! Do not pull the BioFresh drawer by the transparent lid - it is connected to the humidity sensor with thin wires. Damage to the wiring will result in an error E4 on the display and will require flashing the module.
After removing the box, inspect sealing rubber for breaks. If it is torn, replace it with the original one (the article number is indicated in the refrigerator passport). The table below shows the compatibility of rubber bands for popular models:
| Refrigerator model | BioFresh seal article | Notes |
|---|---|---|
| Liebherr CBNesf 4856 | 9086335 | Suitable for boxes with a volume of 28 l |
| Liebherr CBPesf 4815 | 9086336 | Included with mounting clips |
| Liebherr CUag 3311 | 9086334 | Only for BioFresh top drawers |
| Liebherr GPesf 3666 | 9086337 | Seal with reinforced edge |
5. Freezer: how to remove a drawer if it is frozen voltage. To remove them:
In freezers Liebherr (For example, GN 1063 or GP 1476) drawers often freeze to the guides due to incorrect defrosting or power surges. To take them out:
1. Unplug the refrigerator and leave the freezer door open for 15–20 minutes.
2. Pour warm water around the perimeter of the box (not boiling water!) from a spray bottle - this will help melt the ice in the grooves. warm water (not boiling water!) from a spray bottle - this will help melt the ice in the grooves.
3. Gently swing the box left and right while pulling it towards you.
⚠️
Attention! Do not use a knife or other sharp objects to chip away the ice - this will damage antibacterial coating the guides. In models with LowFrost (for example Liebherr GN 1063), an ice crust can hide cracks in the plastic - inspect the box after removal.
If the box still does not lends itself, check whether it is blocked ice maker (in models with the function IceMaker). Sometimes ice accumulates around the water supply tube, and it must first be defrosted with a hairdryer (hold it at a distance of 30 cm so as not to melt the plastic).
6. Common mistakes and how to avoid them
Even experienced users sometimes make mistakes when dismantling boxes. Here are the most common of them and ways to prevent them:
- 🔧 Force instead of technology - an attempt to tear out a drawer without disabling the latches leads to breakage of the guides. Always look for latches or locking buttons.
- ❄️ Ignoring icing —in freezers, you need to defrost the ice first, and not pull the drawer “forcibly.”
- 🔌 Operation under voltage —in models with electronic control (for example, Liebherr SIGN 3556) this can cause a short circuit when moisture gets on the contacts.
- 📏 Incorrect installation back —if the box is inserted crookedly, it will jam. Check the symmetry of the guides.
Pay special attention to models with touch controls (series Liebherr SmartDevice). When dismantling the drawers, do not touch the control panel with wet hands - this may cause the display to malfunction.
7. How to return the box to its place: step-by-step instructions
Installing the box back seems simple, but there are also nuances here. Follow this algorithm:
- Make sure the guides are clean and dry (wipe them with a napkin).
- Insert the drawer at an angle of 10-15° (the front is higher than the back).
- Gently push it in until the latch clicks.
- Check the movement of the drawer - it should move smoothly, without squeaks.
In models with BioFresh system after installing the drawer, calibration of humidity sensorsmay be required. To do this:
1. Press and hold the button BioFresh 5 seconds.
2. Wait for the sound signal (in the series Liebherr CBPesf this is a double squeak).
3. Close the door and do not open it for 10 minutes - during this time the system will stabilize the parameters.
If the box after installation “walks” or falls out, check:
- 🔍 Integrity of the latches - they could break during dismantling.
- 📐 Alignment of guides - sometimes they move when cleaning.
- 🧲 Magnetic seals —in models Liebherr Premium they can interfere with proper fit.
What to do if the box does not lock after installations?
Check whether the metal tongues rails are bent (especially in freezers). If they are warped, carefully straighten them with pliers. As a last resort, order new guides - their article numbers are in the spare parts catalog Liebherr (section "Accessories for refrigerators").
FAQ: Answers to frequently asked questions
Can they be removed box without unplugging the refrigerator?
In most cases, yes, but there are exceptions. If you have a model with electronically controlled (for example, Liebherr SIGN 3556) and function SmartDevice, it is better to turn off the power to avoid settings failure if you accidentally press the touch panel. In mechanical refrigerators (series Liebherr CU) this is not necessary.
Why does not the BioFresh drawer come out even though I pressed the latches?
Probably caused by the blocking humidity sensor, which is not disabled. Try:
- Press and hold the button
BioFresh3 seconds. - Wait until the message appears on the display
OFF. - Try to remove again.
If this does not help, check to see if a foreign object (for example, a piece of cling film) has gotten into the grooves of the guides.
How to clean the guides after removing the drawer?
Use soft sponge i food-grade detergent (for example, Ecover). Do not use abrasives or hard brushes - they will damage antibacterial coating. To disinfect, wipe the guides with a solution of vinegar (1:1 with water). In models with NoFrost after cleaning, be sure to dry the grooves with a hairdryer (cold air!) to avoid icing.
Is it possible to replace a broken box with a non-original one?
Technically yes, but this is fraught with problems:
- 🔄 Violation of tightness - non-original boxes often do not fit in size, which leads to loss of cold.
- ⚠️ Sensor errors —in models with BioFresh or SmartDevice an incompatible drawer can cause malfunctions in the electronic systems.
- 🛠 Loss of warranty —if the refrigerator is under warranty, replacing parts yourself will void it.
Original boxes for Liebherr can be ordered from official dealers or service centers. The article numbers are indicated in the device passport.
What should you do if, after removing the drawer, the refrigerator begins to operate loudly?
Most likely, it has moved fan (in models with NoFrost) or the compressor mounts have become loose. Check:
- Close the door and listen - is the noise coming from the front or the back?
- If it is at the back, the compressor is probably loose. You need to tighten the bolts (access to the rear panel is required).
- If at the front, check if something is blocking the fan (for example, a piece of seal).
If the noise does not disappear, call a technician - this may be a sign of a malfunction of the fan motor.
