Have you noticed that water accumulates under the vegetable drawers in the refrigerator Samsung and ice forms on the back wall? Most likely, the problem lies in a clogged drainage system. This malfunction not only spoils the appearance of the equipment, but can also lead to more serious damage: from constant freezing of the evaporator to failure of the compressor. In 80% of cases, you can clean the drainage in the refrigerator Samsung on your own - without special tools and calling a specialist.
In this article we will analyze three proven cleaning methods (including the "old-fashioned" method with wire and modern chemicals), we will tell you how to avoid typical errors when cleaning, and We'll give you a checklist to prevent blockages. We will pay special attention to models with a system No Frost —their drainage is arranged differently than in drip refrigerators. All instructions are adapted to the current series Samsung (2018–2026 years of manufacture), but before work be sure to unplug the device!
Why the drainage in the refrigerator gets clogged Samsung: 5 main reasons
The drainage system in refrigerators Samsung is responsible for removing condensate that forms during compressor operation. Normally, water flows through a special groove into a reservoir on the rear wall, where it evaporates. If this process is disrupted, moisture begins to accumulate inside the chamber. This is what most often leads to blockage:
- 🍂 Crumbs and food particles. They get into the drainage hole during careless cleaning or when food is stored without packaging (for example, bulk cereals).
- 🧊 Ice plugs. In models with No Frost drainage may freeze due to a faulty defrost heating element or sensor.
- 🧽 Mold and mucus. They develop in the tube when the refrigerator is rarely cleaned, especially if spoiled food is stored inside.
- 🐭 Dust and debris. They penetrate through ventilation grilles (relevant for refrigerators standing in the kitchen without a protective casing).
- 🔧 Deformation of the drain tube. May occur when moving the refrigerator or inaccurate defrosting.
In refrigerators Samsung series RB, RT i RS (with No Frost) the drainage hole is usually located under the back wall of the freezer compartment, and in drip models (for example, SR or BR) - at the bottom of the main chamber, under the vegetable drawer. If your refrigerator is equipped with a system Twin Cooling Plus, there will be two drainage holes: separately for the refrigerator and freezer compartments.
⚠️ Attention: If water accumulates only in the freezer compartment, the problem may not be related to the drainage, but to a malfunction of the defrost system. In this case, cleaning will not help - diagnostics of the heating element or timer is required.
Signs of a clogged drainage system: when is it time to clean
Puddles under vegetable boxes do not always indicate a clogged drainage. Sometimes water appears due to a loose door or overloaded shelves. To pinpoint the problem, check these symptoms:
| Symptom | Probable cause | Does the drain need to be cleaned? |
|---|---|---|
| Water under the vegetable/fruit drawers | Clogged drain hole in the fridge compartment | Yes |
| Ice on the back wall of the freezer | Condensate freezing due to clogged drainage or malfunction No Frost | Yes (if the ice is only at the bottom) |
| Foreign odor from refrigerator | Accumulation of organic residues in the drain tube | Yes |
| The refrigerator often turns on/off | Overheating of the compressor due to excess moisture | Indirectly (requires a comprehensive diagnostics) |
| Water flows along the front wall of the refrigerator | Incorrect angle or clogged drain gutter | Yes (check also the installation level) |
If you observe several signs at the same timecleaning drainage is required. In models Samsung with a display (for example, Family Hub), a problem may be signaled by error code 22E or 25E - they indicate a malfunction of the defrost system, which is often accompanied by clogged drainage.
Method 1: Mechanical cleaning of the drainage hole (suitable for all Samsung models)
This is the simplest and safest method that does not require disassembling the refrigerator. You will need:
- 🧻 Cotton swabs or toothpicks
- 🧴 Dishwashing liquid (for example, Fairy)
- 💦 Warm water and a syringe (or a syringe without a needle)
- 🔧 Flat-head screwdriver (for models with drainage protection)
Step-by-step instructions:
Unplug the refrigerator and remove all food from the bottom of the refrigerator compartment. For models with No Frost also remove the vegetable drawer.
Find the drainage hole - it is located in the center or behind the pallets. In some models Samsung (for example, RS62R5001) the hole is covered with a small plastic plug - pry it off with a screwdriver.
Clean the visible part of the hole with a cotton swab dipped in soap. solution. If the blockage is deep, use a toothpick or a soft wire (for example, from a hanger). Do not use metal objects —they can damage the plastic tube.
Fill the syringe with warm water and sharply inject it into the hole. 3-4 times to rinse the tube. If the water flows freely, the blockage has been eliminated.
Wipe the hole dry and check the refrigerator after 12 hours (during this time, condensation will have accumulated).
Remove food from the lower chamber
Unplug the refrigerator
Find and open the drainage hole
Clean the hole with a cotton swab/toothpick
Rinse the tube with warm water from a syringe
Wipe dry and turn on the refrigerator-->
This method is effective for fresh blockages (crumbs, dust). If the problem is caused by mold or ice jam, more radical measures will be required.
⚠️ Attention: In refrigerators Samsung with a system BioFresh drainage hole may be protected by a special filter. Do not try to remove it - just wash the surface with a soapy solution.
Method 2: Cleaning the drain tube with wire (for complex blockages)
If mechanical cleaning of the hole does not help, the blockage is deeper - in the drain tube, which leads to the reservoir on the back wall of the refrigerator. For cleaning you will need:
- 🔧 Flexible wire with a diameter of 2-3 mm (for example, from a hanger or antenna cable)
- 🧼 Baking soda or a special pipe cleaner (for example, Krot)
- 💧 Hot water (not boiling water!)
- 🧤 Rubber gloves
How to clean the tube:
Unplug the refrigerator and slide it away from the wall to gain access to the back panel. At the bottom you will see a plastic reservoir for collecting condensate - it must be removed by pulling it up.
Locate the outlet of the drainage tube (usually this is a white plastic tube going up from the reservoir). Carefully disconnect it by loosening the clamp.
Insert the wire into the tube from the side of the refrigerator compartment and push it with a rotational motion until you feel that the blockage is broken. Do not press too hard —you can pierce the tube.
Pour a solution of soda into the tube (2 tablespoons per 1 liter of water) or a pipe cleaner diluted according to the instructions. Leave for 15–20 minutes, then rinse with hot water.
Assemble everything in reverse order and check the operation of the refrigerator after a day.
In models Samsung with No Frost (for example, RF23J9011) drainage the tube may be curved - in this case, use flexible cable (sold in plumbing stores). If the tube is damaged, it can be replaced with a silicone hose of a suitable diameter (usually 8–10 mm).
Method 3: Chemical cleaning (for mold and organic blockages)
If mold has grown in the drainage system or organic deposits have accumulated (for example, from juice or milk), mechanical cleaning will be ineffective. In this case, use special means:
- 🧪 Hydrogen peroxide (3%) - it kills mold and disinfects the tube. Pour 50 ml into the hole, then rinse with water.
- 🧴 Pipe cleaner (for example, Tiret or Deboucher) - dissolves fatty and organic deposits. Dilute according to the instructions and pour in for 10–15 minutes.
- 🍋 Citric acid - removes limescale. 2 tbsp. spoons per 1 liter of hot water, pour into the tube and leave for 30 minutes.
Important: After chemical cleaning rinse the tube thoroughly with water (at least 1 l) to remove residual products. Otherwise, they may get on the food or damage the plastic.
For models Samsung with an ionizer Deodorizing Filter (for example, BESPOKE) chemical cleaning should be carried out no more than once every 6 monthsto avoid damaging the filter.
What to do if the chemistry did not help?
If the blockage remains after chemical cleaning, the cause may be in:
1. Deformation of the tube —replacement will be required.
2. Freezing of condensate in the freezer—defrosting is required for 12–24 hours.
3. Malfunctions of the defrost system (for No Frost) - in this case, cleaning the drainage will not solve the problem; repair of the heating element or sensor is needed.
Typical mistakes when cleaning the drainage: what not to do
Even a simple procedure drainage cleaning may not go according to plan if you make these mistakes:
- 🔌 Cleaning without unplugging. Risk of electric shock or short circuit if water gets on electrical components.
- 🔪 Use of sharp objects (knives, knitting needles). May puncture the drain tube or damage the evaporator.
- 🧨 Use of aggressive chemicals (for example Domestos or chlorine). Corrodes plastic and can cause corrosion of metal parts.
- ❄️ Cleaning when the tube is icy. First you need to defrost the refrigerator (especially important for No Frost).
- 🚫 Ignoring checks after cleaning. If you do not make sure that the water flows freely, the blockage may recur in a few days.
In refrigerators Samsung with a system CoolSelect Zone (for example, RF24FSEDBSR), the drainage hole may be hidden under the removable panel - do not try to break it, but find the disassembly instructions for your model.
⚠️ Attention: If after cleaning the drainage, water continues to accumulate, and the refrigerator begins to make a loud noise or frequently turn off, the problem may be compressor malfunctions or a freon leak. In this case, professional diagnostics are required.
Prevention of blockages: how to avoid drainage problems
To ensure that the drainage system in the refrigerator Samsung serves for a long time, follow these recommendations:
- 📅 Clean the drainage hole every 3-6 months (depending on the intensity of use of the refrigerator).
- 🥬 Store food in closed containers, especially bulk products (flour, cereals) and liquid (soups, sauces).
- 🧼 Wash the inside of the refrigerator at least once a month using a soda solution (2 tablespoons per 1 liter of water).
- 🌡️ Monitor the temperature: the refrigerator compartment should be +4...+5°C, in the freezer - −18°C. Hypothermia leads to freezing of the drainage.
- 🔄 Defreeze the refrigerator for 12 hours 1-2 times a year (even if you have No Frost).
For models with No Frost it is also important:
- 🔥 Check the operation of the defrost heating element (if ice forms on the back wall of the freezer).
- 💨 Do not block the ventilation holes with products - this disrupts air circulation and leads to icing.
