A puddle under the refrigerator Samsung No Frost is a problem faced by owners of even new models. The system No Frost should prevent the formation of ice and condensation, but in practice water can accumulate inside or flow out. Most often, malfunctions of the drainage system are to blame, but there are other reasons - from a banal misalignment of the case to serious damage to the compressor.
In this article we will examine 7 main causes of leaks refrigerators Samsung with the system No Frost, including models RB37J5230SA, RL60T6241SL and other popular series. You will learn how to diagnose the problem yourself, when you can get by with cleaning the drainage, and when you need to call a specialist. We will also provide step-by-step instructions for eliminating the most common malfunctions.
⚠️ Important: If water flows not only from below, but also inside the refrigerator compartment (along the back wall), the problem may be associated with failure of the defrosting system. In this case, you cannot do without replacing parts.
1. Clogged drainage hole is the most common cause
In 60% of cases, a leak from below is associated with a clogged drainage channel. In the system No Frost condensate flows down the back wall into a special hole, and then enters a container on the compressor, where it evaporates. If the drain is clogged with crumbs, dust or mold, the water overflows and flows onto the floor.
How to check: Open the refrigerator compartment and inspect the back wall. If water has accumulated under the vegetable drawers and the drainage hole (usually in the lower center) is clogged, the cause has been found. In models Samsung with a display (for example, Family Hub), the blockage may be accompanied by an error 22E or 25E.
- 🔍 Symptoms: A puddle under the refrigerator, water at the bottom of the chamber, an unpleasant odor.
- 🛠️ Solution: Cleaning the drainage with a cotton swab, wire, or rinsing with warm water and soda.
- ⚠️ Danger: If the blockage is prolonged, mold may develop in the drainage tube.

⚠️ Attention: Do not use sharp objects (needles, knives) to clean the drainage - they can damage the plastic tube. If the blockage is deep and cannot be cleaned mechanically, you will need to disassemble the rear panel.
2. Misalignment of the body or legs - water flows past the container
If the refrigerator is not level, condensation from the drainage system may flow not into the evaporation container, but past it - directly onto the floor. This problem often occurs after moving or careless cleaning, when the legs are knocked off the level.
How to diagnose: Take a building level and check the levelness of the installation. If the refrigerator is tilted backwards (a common occurrence), water will accumulate under the front. In models Samsung with the function Twin Cooling Plus misalignment can also disrupt air circulation, which will aggravate the problem.
- 📏 Permissible slope: No more than 1-2° forward (for a tight fit of the door).
- 🔧 Adjustment: Twist the front legs clockwise to tilt forward.
- 🚫 Error: Do not place homemade pads (books, planks) under the legs - this interferes with ventilation.
3. Malfunction of the evaporator heater (defroster)
In the system No Frost responsible for defrosting ice heating element (defroster). If it burns out, the ice on the evaporator does not melt, the drainage hole freezes over, and water begins to flow past the container. This breakdown is typical for refrigerators Samsung over 5 years old (for example, models RL-44 QEBS, RB-30 J3200).
Symptoms:
- ❄️ A thick layer of ice forms on the back wall of the freezer.
- 💧 Water does not flow constantly, but in periods (during defrosting cycles).
- 🔴 An error may appear on the display
21Eor24E.
| Samsung model | Typical errors in the event of a breakdown defroster | Replacement cost (approximately) |
|---|---|---|
| RB37J5230SA | 21E, 24E |
3 500 – 5 000 ₽ |
| RL60T6241SL | 22E, 25E |
4 000 – 6 000 ₽ |
| RT-43 K6030 | 16E (less often) |
3 000 – 4 500 ₽ |
⚠️ Attention: Replacing the heater requires disassembling the freezer chamber and soldering the contacts. In refrigerators Samsung with an inverter compressor (series Digital Inverter) with unqualified repairs, the control board may burn out.
4. Breakdown of the defrost sensor or timer
If the heater is working, but the ice still does not melt, the problem may lie in defrost sensor (thermostat) or defrost timer. These elements control the defroster switching cycles. If they fail, the system No Frost stops working correctly and water begins to accumulate.
How to determine:
- 🕒 The refrigerator works without stopping (the compressor does not turn off).
- ❄️ A “coat” of ice forms in the freezer, despite No Frost.
- 💦 Water flows only after long-term operation (4-6 hours).
For diagnostics you will need a multimeter:
- Unplug the refrigerator and remove the back panel of the freezer.
- Find the defrost sensor (usually attached to the evaporator).
- Ring the contacts: the resistance should be ~5–10 kOhm at room temperature.
How to check the defrost timer without a multimeter?
Turn the timer knob (usually located behind the front panel or in the freezer) clockwise until it clicks. If after 20–30 minutes the heater does not turn on, the timer is faulty.
5. Crack or freezing of the drainage tube
In refrigerators Samsung the drainage tube is made of thin plastic, which can burst over time due to temperature changes or mechanical stress. Also, the tube can freeze if the refrigerator has been left turned off for a long time. cold room (for example, at the dacha in winter).
Symptoms:
- 💧 Water flows even after cleaning the drainage hole.
- 🧊 Frost or cracks are visible on the tube (inspect it from the back of the refrigerator).
- 🔊 During operation, a gurgling sound is heard (water passes through a crack).
⚠️ Attention: If the tube bursts inside the case, you will need to completely disassemble the refrigerator. In models with Total No Frost (for example, RS62R5001M9), access to the tube is difficult - it is better to contact a specialist. service.
6. Malfunction of the condensate container
There is a plastic container installed at the bottom of the refrigerator above the compressor, where water flows from the drainage Over time, it can:
- 🔥 Melt due to overheating of the compressor. (typical for models with a linear compressor).
- 💔 Crack from vibration or mechanical damage.
- 🧊 Overflow due to a clogged drain hole in the container itself.
How to check: Move the refrigerator, remove the bottom cover and inspect the container. If it is deformed or there are puddles in it, replacement is required. In some models Samsung (for example, RB-33 J3420) the container is integrated into the body, and can only be replaced together with the tray. compressor.

7. Problems with the door seal
A worn or dirty seal allows warm air to pass through, causing condensation to form on the back wall. Water flows into the drainage, but if there is too much of it, the system does not have time to evaporate it, and the excess flows out.
Signs:
- 🚪 The door does not close tightly (a gap is visible or a draft is felt).
- ❄️ On the back frost appears on the wall of the refrigerator compartment.
- 💦 Puddles form after a long period of inactivity with the door open.
How to eliminate:
- Clean the seal with soapy water (no abrasives!).
- Check the magnetic tape for cracks.
- If the seal is deformed, replace it (original ones for Samsung cost ~2,000–3,500 ₽).
