The situation when water accumulates inside the refrigerator compartment or under the unit can take any owner of household appliances by surprise. Most often, the problem lies in a banal violation of operating rules, but sometimes a serious refrigerator repair replacement of components is required. If you notice a puddle on the kitchen floor or a wet bottom of the chamber, do not panic, since in most cases you can fix the problem yourself.
The first thing to do is to determine the location of the problem. Water may appear inside on shelves, leak from under crisper drawers, or collect in a drip tray at the back of the unit. Understanding exactly where the moisture comes from will help you narrow down your search and avoid calling a professional where you can do it yourself.
Ignoring the problem can lead to food spoilage and the appearance of an unpleasant odor. Moisture promotes the growth of bacteria and mold, which is critical for food storage. Therefore, if you discover that water is dripping in the refrigerator, you must immediately begin diagnostics.
Natural condensation and temperature violations
The most common reason for the appearance of moisture is the physics of the process. Warm air entering the chamber cools down, and the steam it contains turns into liquid. If you frequently open the door or leave it ajar, the amount of heat entering will increase dramatically. The cooling system does not have time to quickly evaporate all the accumulated moisture, and it begins to drip onto the shelves or products.
It is also important to check whether you are putting hot or warm foods in the chamber. Even a slightly warmed soup placed on a shelf will cause abundant steam formation. Modern refrigerators Bosch, LG or Samsung are sensitive to heat stress, and their drainage system may not cope with a sudden jump in humidity.
⚠️ Attention: Never put hot pots on the refrigerator shelves. This not only causes leaks, but also causes the compressor to wear out, which shortens the service life of the equipment.
Check the tightness of the fit sealing gum to the housing. If the cuff is worn, dirty or deformed, warm air from the room will constantly enter the chamber. This will lead to the formation of a “fur coat” on the back wall, which will turn into water during defrosting.
Clogged drainage hole
In refrigerators with a drip defrosting system (Direct Cool), water flows down the back wall into a special groove and leaves through the drainage hole. Over time, this channel can become clogged with crumbs, mold, or ice. As a result, the moisture does not leave, it overflows the groove and flows out onto the bottom shelf or into the vegetable drawer.
To fix this problem, you need to find a hole on the back wall, usually it is located in the center at the bottom. Clean it carefully with a special brush or soft wire. You can use a syringe with warm water to push the blockage deeper into the evaporation system.
☑️ Cleaning the drain
If water continues to drip after cleaning, the water drainage tube in the freezer area may have frozen. In this case, the unit will need to be completely defrosted within 10-12 hours. Leave the doors open, having first removed all the products.
Malfunctions of the No Frost system
Owners of equipment with the system No Frost are often surprised to find water inside, because these models are considered “not requiring defrosting.” However, they also have a drainage that removes melt water from the evaporator. If the defrost heater (TEH) or the timer fails, a coat of ice builds up on the evaporator.
When the defrost mode is turned on, this ice melts, but due to a malfunction of the sensors or heater, the water does not have time to evaporate or go into the drain. It overflows the pan and begins to drip into the chamber or flow out. In such models, replacement The defrost heating element or the temperature sensor is often required.
⚠️ Attention: If ice is frozen on the back wall in the No Frost refrigerator, and water is dripping inside, this is a sure sign of a failure in the defrost cycle. Operation in this mode is dangerous for the compressor.
Diagnostics of the No Frost system requires a multimeter and electrical skills. It is necessary to “ring” the heater and check the resistance of the sensors. If you are not confident in your abilities, it is better to contact a service center, since disassembling the rear panel in such models is more difficult than in conventional ones.
Displacement or damage to the water collection tray
On the back wall of the refrigerator, on the outside, there is a plastic tray (evaporator), where water flows from the drainage tube. Water evaporates from there naturally due to the heat from the operating compressor. If this tray becomes dislodged, cracked, or the tube comes off it, water will drip directly onto the kitchen floor.
Check the position of the tube coming out of the back of the unit. It should be directed strictly inside the tray. Sometimes, when moving the refrigerator while cleaning, the tube may come off or burst. Also, the tray itself could have cracked due to old plastic or mechanical shock.
If the tray is intact, but there is still water on the floor, the evaporator itself may be overfilled. This happens if the room humidity is very high and the water does not have time to evaporate. In this case, you can carefully drain the excess liquid with a syringe or sponge, but it is better to check the ventilation around the back wall of the refrigerator.
Why might the tray overflow?
In hot summers or in damp rooms, evaporation slows down. If the tray is full, water will begin to overflow. The solution is to wipe the tray and ensure better air flow to the back wall.
Defects in the casing and thermal insulation
Sometimes water does not drip from the inside, but condenses on the outside on the walls of the refrigerator. This phenomenon is called a “crying refrigerator” and indicates a violation of the seal of the housing or problems with thermal insulation. If air gets between the internal and external circuits or the insulation is destroyed, dew appears on the outer walls.
Improper installation may also be the cause of external moisture. If the refrigerator is too close to the wall or in a niche without gaps, air circulation is disrupted. The side walls heat up, and then, meeting cold air in a poorly ventilated space, form condensation.
Check whether the housing is damaged. Cracks or dents in the plastic can compromise the structure of the thermal barrier. In older models, the metal casing could rot from the inside, which also leads to moisture and corrosion.
Table: Diagnosis of the causes of leakage
To quickly determine the problem, use the table below. It will help compare symptoms with probable causes.
| Symptom | Probable cause | Difficulty of repair |
|---|---|---|
| Water on the floor under the refrigerator | The tray is displaced or clogged drainage | Low |
| Puddle inside in the vegetable drawer | The drainage hole is clogged | Low |
| Water dripping from the ceiling of the chamber | System malfunction No Frost | High |
| Condensation on external walls | Poor ventilation or housing defect | Medium |
| Water has appeared after defrosting | The tray did not have time to drain or burst | Low |
As can be seen from the table, most problems can be solved by simple cleaning or adjustment. However, if you notice that the water has a strange color or smell, this may indicate more serious internal damage, such as a refrigerant oil leak (although this is rare for watery puddles).
Mechanical damage and manufacturing defects
Do not discount the possibility of manufacturing defects or mechanical damage during transportation. A crack in the plastic gutter housing inside the chamber may be microscopic, but large enough to allow water to drip down. Carefully inspect all plastic elements for defects.
If the refrigerator is new and has just been delivered, let it stand unplugged for several hours. During transportation, oil could get into the circuit, and moisture could freeze in the tubes. A sudden switch-on may lead to incorrect operation of the defrost system in the first cycles.
Also check whether the refrigerator is level. If the unit is skewed, the water in the drainage gutter may not reach the drain hole, but overflow into the chamber. Adjust the legs to provide a slight tilt back for proper drainage.
⚠️ Attention: If you find that the liquid dripping from the refrigerator has an oily structure or a strong chemical smell, immediately unplug the appliance. This may be a leak of freon with oil, which requires professional repair.
Prevention and proper care
So that the problem “what is dripping in the refrigerator” has not returned, it is important to follow the operating rules. Regularly, at least once every six months, carry out preventive cleaning of the drainage hole. It will take a couple of minutes, but it will save you from a flood.
Monitor the condition of the food: do not store open liquids without lids, they increase humidity. Check the condition of the seal and wipe it from grease and dirt so that it remains elastic.
If you see too much ice forming on the back wall, do not wait for complete freezing. Defrost ahead of time. Modern models Indesit or Atlant may have different operating efficiency in conditions of hard water or voltage surges, which also affects the formation of ice.
Why does water drip in the refrigerator after defrosting?
After defrosting, water may drip if the drainage hole remains clogged ice or mud. It is also possible that you turned on the refrigerator too early, and the water from the grooves has not yet had time to drain. Let the unit stand dry for 2-3 hours before turning it on.
Is it dangerous if water drips in the refrigerator?
Water itself (condensation) is not dangerous, but it creates an environment for bacteria. The danger is electricity: if water reaches the wiring or contacts, a short circuit may occur. Also, a puddle on the floor can damage the floor covering.
Is it possible to use a refrigerator if it is leaking?
For a short time - it is possible if you have time to eliminate the cause (for example, clean the drainage). But if it leaks due to a malfunction of the No Frost system or a freon leak, operation will lead to breakdown of the compressor. It is better to temporarily turn off the device.
How to clean the drainage if there is no brush?
You can use a soft wire (for example, from a hanger), twisted into a bundle, or a long sushi stick. The main thing is to act carefully so as not to pierce the plastic tube. Rinsing with warm water through a syringe without a needle is effective.
