Detection of a puddle at the bottom of the refrigerator compartment or accumulation of moisture under containers for vegetables is a signal that cannot be ignored. Equipment owners Liebherr often encounter this problem, believing that there has been a serious breakdown of the compressor or defrost system. However, in most cases, the reason lies in a simple clogging of the drainage system or violation of operating rules, which can be easily eliminated on your own.
The accumulation of condensation can lead to spoilage of food, the appearance of an unpleasant odor and even a short circuit if water reaches the electrical contacts. The NoFrost system or drip moisture removal system in modern models is designed to remove excess liquid automatically. If this process is disrupted, the water begins to look for a way out, collecting at the bottom of the chamber.
Before calling a technician, it is worth conducting a thorough diagnosis. Often the problem is solved in 15 minutes by simple cleaning. In this article, we will analyze the main reasons for the appearance of water under vegetable boxes, consider the design features of the models Liebherr and provide a step-by-step algorithm of actions to restore normal operation of the unit.
Design features of moisture removal in Liebherr
Refrigerators Liebherr equipped with a well-thought-out air circulation and condensate removal system. In models with technology NoFrost moisture settles on the evaporator, which is hidden behind the back wall. The defrost heating element is periodically turned on, the ice melts, and the water flows into a special pan, from where it evaporates. If you see water in the refrigerator compartment under the drawers, this often indicates that the water does not have time to evaporate or flows past the gutter.
In Drop Cooling models, moisture condenses on the back wall and flows down the gutter into the drainage hole. This hole is a critical component. It is located just above where the vegetable boxes are installed. If the diameter of the hole is reduced due to dirt, water overflows the edge of the gutter and ends up at the bottom of the chamber.
It is important to understand the difference between condensation and a refrigerant leak. Condensation is ordinary water, often cloudy or with the smell of food. If there is an oily liquid at the bottom with a pungent chemical odor, this may indicate depressurization of the circuit, which requires immediate intervention from a service center.
⚠️ Attention: If the water has an oily structure or a pungent chemical odor, immediately unplug the refrigerator and do not try to clean it yourself. This is a sign of a freon or compressor oil leak.
Clogged drainage hole: the main reason
The most common reason why water accumulates in a refrigerator under the drawers is a clogged drainage channel. During food storage, small crumbs, packaging particles, mold or slime may end up in the drain. Over time, these deposits harden and form a plug. Liebherr Water accumulates under the drawers - this is a blockage of the drainage channel. During food storage, small crumbs, packaging particles, mold or slime may end up in the drain. Over time, these deposits harden and form a plug.
When the drain is blocked, melt water does not flow into the evaporation tray under the compressor. The water level in the gutter rises, and it begins to overflow over the sides, falling onto the shelf with vegetables and then to the bottom of the refrigerator. This happens especially often if you store food without packaging or allow loose products to get into the chamber.
To clean it, you will need a soft wire, a cotton swab or a special brush-brush. Never use sharp metal objects that could damage the plastic or puncture the tube. Carefully insert the tool into the hole and make rotational movements, trying to push the blockage deeper or remove it out.
☑️ Algorithm for cleaning the drainage
After mechanical cleaning, it is recommended to rinse the channel with warm water. You can use a medical bulb or a large syringe without a needle. The water pressure will help wash away any remaining dirt and check the permeability of the system. If the water leaves quickly and with a characteristic gurgle, then the problem is solved.
Incorrect installation of products and circulation problems
Often users themselves create conditions for the formation of excess condensation, without knowing it. If food in the refrigerator compartment Liebherr is located too close to the back wall, it may block air circulation channels or wash condensation directly onto the shelves, bypassing the gutter.
It is also important to monitor the packaging. Hot or warm food placed in the chamber releases a huge amount of steam. The cooling system cannot cope with a sharp increase in humidity, and excess water settles on the walls and bottom. In addition, storing liquids in open containers significantly increases the humidity inside the chamber.
Check that the food is not tightly against the back wall. There should be a gap of at least 2-3 centimeters for free air flow. If you have just defrosted the refrigerator or loaded a lot of food, give the equipment time to return to operating mode.
Problems with the door seal
The tightness of the chamber is the key to proper operation refrigerator. If the rubber seal (cuff) of the door Liebherr is damaged, dirty, or simply does not fit tightly, warm, moist air from the room constantly enters the chamber. This air cools, and the moisture it contains falls out in the form of abundant condensation, which the drainage system may not have time to remove.
Check the seal around the entire perimeter. There should be no cracks, tears or sticky residue on it. Often the problem can be solved by simply washing the seal with warm soapy water. Grease and dirt prevent the magnetic tape from adhering tightly to the body.
There is a simple test with a sheet of paper. Clamp a sheet of paper with the refrigerator door in different places around the perimeter. If the sheet is removed easily, without resistance, it means that the seal does not hold the cold in this place. In such cases, it may be necessary to adjust the door hinges or completely replace the rubber seal.
| Symptom | Probable cause | Action |
|---|---|---|
| Water only under the drawers | Drainage clogged holes | Cleaning the channel |
| Ice on the back wall | Faulty defrost sensor | Electronics diagnostics |
| Water at the door | Leaky seal fit | Cleaning or replacing the cuff |
| A lot of water after loading | Inserting warm products | Waiting for the mode to normalize |
Malfunctions of the defrost system and sensors
If mechanical cleaning does not help, the problem may lie deeper. In refrigerators Liebherr with the NoFrost system, a complex of sensors and heaters is responsible for removing moisture. If it fails Defrost heating element, the evaporator becomes covered with ice. When the heater is turned on (or during manual defrosting), this ice melts, and the volume of water exceeds the drainage capacity, or water flows past the gutter due to an ice plug inside the channel.
Also often the culprit is a defrost sensor or timer. They may “stick” in the cooling mode without starting the defrost cycle, or, conversely, turn on the heating too often. As a result, an ice plug forms in the drainage channel inside the case, which cannot be reached from the outside with a brush.
How to defrost an ice plug in the drainage?
If you suspect that the drainage channel is frozen inside the case (water sits in the gutter and does not leave even when cleaning), you will need to completely defrost the refrigerator. Unplug the unit, open the doors and leave it for at least 24 hours. It is best to place a container under the bottom to collect melting water. Only complete thawing of the ice inside the channel will restore passability.
In some cases, replacing the defrost sensor or checking the wiring is required. If, after 24 hours of defrosting, the problem with water under the drawers returns after a few days, you need to contact a specialist to diagnose the electrical circuit.
Errors in setting the temperature mode
Too low a temperature in the refrigerator compartment can contribute to the formation of excessive condensation. If you set the "Super Cool" mode or the minimum temperature settings, the humidity inside the chamber drops sharply, but the rate of condensation on cold surfaces increases. The system may not be able to cope with such a volume of moisture.
For normal storage of food, a temperature of +3 to +5 degrees Celsius is sufficient. Check the settings on your Liebherrdisplay. Also make sure that the temperature sensor is not covered with food, otherwise the refrigerator will work in enhanced mode, thinking that the chamber is warm.
When professional repairs are required
Despite the reliability of the equipment Liebherr, there are situations when you cannot do without a specialist. If you have cleaned the drainage, checked the seal, defrosted the unit, but water continues to accumulate under the drawers, the water collection tray under the compressor itself may be damaged or the tightness of the inner tube may be broken.
Also an alarming signal is the appearance of rust on the bottom of the chamber or swelling of the internal plastic. This may indicate that the water has been stagnant for a long time and has begun to destroy materials. In this case, it may be necessary to replace the inner box or repair the drainage system with disassembling the rear wall.
Do not ignore the problem. Constant moisture is an ideal environment for the growth of bacteria and mold, which directly affects the safety of products. If independent measures do not produce results within a week, sign up for diagnostics.
⚠️ Attention: Specifications and location of components may vary depending on the specific model and year of manufacture. Always check the official user manual for your model Liebherr before disassembling the units.
Preventing the appearance of moisture
What is the problem with water under vegetable boxes have not returned, it is important to follow simple rules of prevention. Check the drainage hole regularly, at least once a quarter. Wipe the back of the refrigerator with a soft cloth, removing dirt before it goes down the drain.
Monitor the condition of the food. Do not store perishable vegetables in open bags, and clean up spills immediately. Make sure that food packaging does not touch the back wall, where active cooling and condensation occurs.
Regular cleaning of the refrigerator using safe products will help keep the moisture removal system in working order. Use a solution of baking soda or special products for household appliances, avoiding aggressive chemicals that can damage the plastic and rubber of the seals.
Frequently asked questions (FAQ)
Why does water appear only in summer?
In summer, indoor air humidity is much higher. Each time the door is opened, more moist air enters the chamber and condenses. The drainage system may not be able to cope with the increased load, especially if it is slightly dirty. It is recommended to check the cleanliness of the drain more often during hot periods.
Is it possible to lubricate the drainage hole with oil?
No, it is strictly forbidden to lubricate the drainage hole with oil. The oil will collect dust and dirt, creating a dense plug that is very difficult to remove. In addition, oil can destroy some types of plastic and rubber. Use only water for rinsing.
Is it normal that water appears immediately after defrosting?
If you defrosted the refrigerator manually and poured a lot of water on the back wall, some of it may not have had time to go into the drainage and remained at the bottom. This is fine. However, if water appears during normal operation without defrosting, this is a sign of a malfunction or blockage.
How often should you clean the drainage in a Liebherr?
Preventive cleaning is recommended every 6-12 months. If you notice that the water in the gutter drains slower than usual, cleaning should be done immediately, without waiting for a puddle to appear at the bottom.
