Have you noticed that water in the refrigerator has stopped flowing into the dispenser or is accumulating in places not intended for this? The reason most often lies in a blockage holes for draining condensate or the water supply tube. This problem is typical both for models with the system No Frostand for drip refrigerators Samsung, LG, Indesit and other brands. It cannot be ignored: the accumulation of moisture leads to the appearance of mold, an unpleasant odor and even breakdown of the compressor due to increased load.
In this article you will find 7 proven cleaning methods from simple mechanical ones to the use of specialized means. We will look at how to determine the exact cause of the blockage, what tools you will need, and give step-by-step instructions taking into account the features of different cooling systems. We’ll also tell you how to avoid repeated problems and when it’s still worth calling a specialist.
Spoiler: in 80% of cases the problem is solved in 15-30 minutes without disassembling the equipment. The main thing is to act carefully and not use improvised means that can damage plastic parts (for example, metal wires or aggressive acids).
Why the water hole gets clogged: 5 main reasons
Before you start cleaning, it is important to understand what exactly caused the blockage. This will help you choose the right method and prevent the problem from recurring. Here are the most common culprits:
- 🧊 Ice and frost. In refrigerators, moisture must evaporate through a special hole, but if the system does not work correctly, an ice plug forms there. This is often due to No Frost moisture should evaporate through a special hole, but if the system does not work correctly, an ice plug will form there. This is often associated with
malfunction of the evaporator heating elementor defrost sensor. - 🍂 Dust and debris. Over time, crumbs, food particles, and dust get into the drainage hole - especially if the refrigerator is in a highly dusty room (for example, in a kitchen without a hood).
- 🦠 Mold and bacteria. A humid environment is ideal for the proliferation of microorganisms. If the hole has not been cleaned for a long time, a mucous coating or even fungal colonies may form there.
- 🧪 Mineral deposits. In regions with hard water, calcium and magnesium salts accumulate in tubes and holes, narrowing the lumen. This is true for models with water dispenser (for example, Samsung RF23 or LG InstaView).
- 🔧 Mechanical damage. Sometimes the hole is blocked by a piece of door seal, a piece of plastic, or even an insect (for example, mole).
As a rule in 60% of cases. the blockage is caused by a combination of ice and organic debris - especially if the refrigerator has not been defrosted for more than a year. In models with a dispenser, water may stop flowing due to a clogged filter or limescale in the tubes.
⚠️ Attention: If the refrigerator No Frost starts to “cry” (water accumulates on the back wall), and ice forms in the freezer, the problem may not be in the drainage hole, but in malfunctions of the defrosting system. In this case, cleaning will not help, cleaning is necessary. repair.
Signs of a blockage: how to understand that the hole needs cleaning
It is not always obvious that the problem is in the drainage hole. Here are the key symptoms that should alert you:
- 💧 Water accumulates under the vegetable drawers or on. the bottom of the refrigerator compartment (sometimes even leaks onto the floor).
- ❄️ A thick layer of ice forms in the freezeralthough the system No Frost should prevent this.
- 🌫️ An unpleasant odor appears - especially if it resembles mustiness or rot.
- 🚰 The water dispenser works intermittently or does not supply water at all (the filter has recently been changed).
- 🔊 The refrigerator has become louder - this may be due with increased load on the compressor due to a violation of heat exchange.
If you notice at least 2-3 signs from the list, it’s time to act. But first, make sure that the problem is not something else:
| Symptom | Possible cause (other than blockage) | How to check |
|---|---|---|
| Water under the drawers | The door is not closed tightly | Check the seal for damage |
| Ice in the freezer | The thermostat is faulty | Check whether the temperature on the display corresponds to the real one (use a separate thermometer) |
| The dispenser does not work | The filter is clogged or broken pump | Check if the filter replacement indicator is on |
| Unpleasant odor | Spoiled food | Remove all contents and wash the refrigerator |
If alternative causes are excluded, proceed to cleaning. But first, prepare everything you need.
Preparing for cleaning: tools and safety precautions
To clean the drainage hole or water supply tube you will need:
- 🧻 Absorbent wipes or towels - to collect water.
- 🔦 Flashlight —to better see the hole (especially in models Bosch or Liebherrwhere it is located deep).
- 🧴 Warm water and soap —for preliminary cleaning.
- 🧼 Toothbrush or cotton swabs —for mechanical cleaning.
- 🩹 Syringe (10–20 ml) or rubber bulb —for rinsing.
- 🧪 Vinegar or citric acid —to remove limescale (for water supply pipes only!).
- 🛠️ Plastic tube or knitting needle —to push through the blockage (metal cannot be used!).
Also prepare the refrigerator:
- Unplug it (required!).
- Get all the products and shelves - you need free access to the back wall.
- If there is a lot of ice in the freezer, let it melt (you can speed it up process by placing a container of hot water inside).
- Tilt the refrigerator slightly back so that water does not flow onto the floor.
⚠️ Attention: Never use for cleaning boiling water —it can deform plastic parts. Optimum water temperature: 40–50°C. Also avoid. aggressive agents such as “Mole” or bleach - they can damage the rubber seals and leave a persistent chemical odor.

Method 1: Mechanical cleaning of the drainage hole (for all models)
This is the simplest and safest method, which is suitable for 90% household refrigerators, including Atlant, Beko and Whirlpool. Follow the instructions:
- Find the hole. It is located on the back wall of the refrigerator compartment, usually in the center or left. In models with No Frost may be hidden behind a plastic panel (carefully pry it off with a flat-head screwdriver).
- Rinse the hole with warm water. Use a syringe or rubber bulb to pressurize the debris out. Repeat 3-4 times.
- Clean with a straw or a cotton swab. Insert it into the hole and carefully twist it. If you feel resistance, there is a blockage.
- Blow out the hole. You can use a bulb or even your own exhalation (through a straw). This will help remove any remaining particles.
- Check the drain pan. It is located at the back of the refrigerator, under the compressor. If water has accumulated there, cleaning helped, but the drainage tube should also be washed (more on this below).
If after cleaning water still accumulates, proceed to the next method.
Method 2: Cleaning the drain tube (if the water does not go into the pan)
If mechanical cleaning of the hole did not help, the problem may be deeper - in drain tubewhich leads to the pallet. Its blockage leads to water accumulating inside the chamber or leaking onto the floor. To clean the tube:
- Move the refrigerator away from the wall and find the tube at the back (usually it is located next to the compressor and leads into the pan).
- Disconnect the tube away from the pan. Be careful - there may be water in it!
- Rinse the tube:
- 🧼 First run warm soapy water through it (you can use a syringe).
- 🧪 If the blockage is persistent, fill it vinegar solution (1:1 with water) and leave for 10-15 minutes, then rinse.
- 🌀 To push the plug, use a flexible cable (for example, from an old charger) or insulated wire.
In some models (for example, LG GA-B489) the tube may be rigidly fixed. In this case, do not try to disconnect it - just rinse it through the hole in the chamber using a syringe with a long tube.
⚠️ Attention: If the tube is damaged (cracks, breaks), it must be replaced. You can temporarily isolate the damage with a heat-shrink tube, but this is not a long-term solution.
What to do if the tube is clogged with ice?
If an ice plug has formed in the tube (important for refrigerators that have not been defrosted for a long time), do not try to push it through mechanically - you risk damaging the plastic. Instead:
1. Turn off the refrigerator and leave the door open for 6–8 hours (the ice should melt on its own).
2. If you don’t have time, use a hair dryer at minimum power, directing warm air into the hole (keep the hair dryer at a distance of 20–30 cm so as not to deform the plastic).
3. After thawing, rinse the tube with warm water and vinegar (1:3) to dissolve any remaining plaque.
Method 3: Cleaning the water supply system in the dispenser
If your refrigerator has one water dispenser (as in Samsung RF23 or LG InstaView Door-in-Door), but the water does not flow or flows in a weak stream, the problem may be:
- 🔌 Clog in the tube supply (from filter to dispenser).
- 🧻 Dirty strainer at the entrance to the dispenser.
- 🧊 Formation of limescale in the tap.
For cleaning:
- Turn off the water supply (close the tap on the pipe leading to the refrigerator).
- Remove the dispenser cover. Usually it is attached to latches - pry it off with a flat screwdriver.
- Take out the mesh filter (if any) and rinse it under running water. If heavily soiled, soak in a solution of citric acid (1 tablespoon per 200 ml of water) for 30 minutes.
- Clean the supply tube:
- Disconnect it from the dispenser (you may need a hose wrench).
- Rinse the tube with a solution of vinegar (1:1) using a syringe.
- Blow with compressed air (you can use a bicycle pump).
After assembly, turn on the water and check the pressure. If the problem persists, the main filter may be clogged (it needs to be replaced) or the main filter may be faulty. A clogged filter not only worsens the pressure, but also becomes a breeding ground for bacteria. main filter (it needs to be replaced) or faulty water supply pump.
Method 4: Using specialized products
If mechanical cleaning does not help or the blockage is caused by limescale/mold, you can use chemicals. But here it is important to choose the right composition:
| Type of blockage | Recommended product | How to use | Precautionary measures |
|---|---|---|---|
| Limescale | Vinegar 9% or citric acid | A 1:1 solution with water, pour into the hole for 15-20 minutes, then rinse | Do not use undiluted vinegar - it can damage rubber parts |
| Mold/bacteria | Hydrogen peroxide 3% | Apply to a cotton swab and treat the hole, rinse with water after 10 minutes | Do not mix with vinegar - a chemical reaction is possible |
| Fat deposits | Dishwashing liquid (for example, Fairy) | Solution with water (1:10), pour in with a syringe, rinse after 30 minutes | Avoid contact with door seals |
| Complex blockages | Special products (for example, BG CF6 for drainage systems) | Follow the instructions on the package | Use only in a well-ventilated area |
After using any chemical be sure to rinse the system 2-3 times with clean waterto remove residual reagents. Otherwise, they may get on the food or damage the plastic.
To prevent mold, you can pour a soda solution (1 tsp) into the drainage hole once every 3 months. l per 200 ml of water). This safely and effectively kills bacteria.
Method 5: Steam cleaning (for persistent dirt)
If the blockage is caused by fatty deposits or old plaque that cannot be washed, you can use steam generator or even a regular iron with a function. steaming. This method is suitable for refrigerators with metal or heat-resistant plastic parts (check the instructions!).
How to proceed:
- Pour water into the steam generator (if using an iron - maximum fill level).
- Direct a stream of steam into the drainage hole at a distance of 5-10 cm. Hold for 10-15 seconds.
- Repeat 2-3 times with an interval of 1 minute (let the condensate drain).
- After steam treatment, rinse the hole with warm water.
Steam not only dissolves grease and plaque, but also disinfects the system. However, be careful:
- ❌ Do not direct steam at electronic components (display, buttons).
- ❌ Do not use the method if there are visible cracks on plastic in the refrigerator, hot steam can increase them.
- ❌ Do not use for models with thin plastic tubes (for example, in some Indesit), which may deformed.
When to call a technician: 5 signs of serious damage
Not all problems with water in the refrigerator can be solved by cleaning. Here are cases when it is better to contact a specialist:
- 🔧 After cleaning, water continues to accumulateand the drainage hole is free - there may be a problem. in
malfunction of the evaporator heating elementor defrost sensor. - ❄️ The freezer does not freeze, and the refrigerator compartment is too warm - this may indicate
freon leakageor compressor breakdown. - 💡 The display shows an error (for example,
E1,dHorFFc refrigerators Samsung) - see the instructions for decoding the code. - 🔌 The water dispenser does not work at all, although the tubes are clean - the fault is
broken pumpor the electronic module. - 🔊 The refrigerator makes unusual sounds (grinding, knocking) - this may be due to
fan failureor compressor.
The cost of repair depends on the breakdown:
| Problem | Approximate cost of repair (2026) | Difficulty |
|---|---|---|
| Replacing the evaporator heating element | from 3,500 ₽ | Average |
| Repair of the No Frost system | from 4,000 ₽ | High |
| Replacement of water supply pump | from 2,500 ₽ | Low |
| Freon leakage + refill | from 5,000 ₽ | High |
If the refrigerator is under warranty, do not disassemble it yourself - this may result in refusal of free repairs. Contact the brand service center (Samsung, LG, Bosch etc.) with a receipt and warranty card.
⚠️ Attention: Prices and terms of warranty service may vary depending on the region and model. Check details with the official service center or the seller.
FAQ: Frequently asked questions about cleaning the water hole
Can I use a wire or needle for cleaning?
Use metal objects (needles, wire, paper clips) not —they can scratch the plastic or get stuck in the tube. It’s better to take a plastic cocktail straw, a toothpick or a special brush for cleaning.
How often should you clean the drainage hole?
Recommended frequency:
- For refrigerators No Frost: 1 time every 6 months.
- For drip models: 1 time every 3 months (due to more active condensation formation).
- With intensive use of the dispenser: 1 time every 2 months (to prevent limescale).
What to do if after cleaning Is there an unpleasant odor left in the refrigerator?
The odor may remain due to bacteria in the drainage system. Try:
- Rinse the hole and tube with a soda solution (2 tablespoons per 1 liter of water).
- Put an open pack of soda or activated carbon in the refrigerator for 2-3 days.
- Use a special odor absorber (for example, Bork K701).
If the smell does not go away, the mold may have spread to the seals or internal parts. In this case, only professional cleaning will help.
Is it possible to clean the hole without turning off the refrigerator?
Technically, yes, but highly not recommended. electric shock). Secondly, without turning it off, it is difficult to tilt the refrigerator to access the tube. If you still decide to clean it on the go, at least remove the plug from the socket while working with water!
Will defrosting the refrigerator help get rid of the blockage?
Partly yes, if the problem is in iceblocking the hole. But if the blockage is caused by debris, mold or limescale, defrosting will not help - you need mechanical or chemical cleaning. By the way, refrigerators need to be defrosted at least once a year, even if there is no ice. visible. No Frost You need to defrost it at least once a year, even if the ice is not visible.
