How to clean the tube in a Samsung No Frost refrigerator: a complete guide with photos and tips

Refrigerators Samsung No Frost are famous for their automatic defrosting system, but even they are not immune from blockages in the drainage tube. If you notice water under the crisper drawers, a foul odor, or ice in the freezer, the problem is most likely a clogged tube. This malfunction not only spoils the products, but also causes the compressor to wear out, increasing energy consumption.

In this article we will examine it with our own hands, without resorting to an expensive service center. You will learn about the causes of blockages, the necessary tools and step-by-step actions - from preparation to final inspection. And also get tips on how to avoid repeated problems and when it’s still worth calling a specialist. how to clean the tube in a Samsung No Frost refrigerator do it yourself, without resorting to an expensive service center.

Why does the drain tube get clogged in No Frost?

System No Frost in refrigerators Samsung assumes circulation of cold air using a fan. The humidity that is generated during operation condenses on the evaporator and flows through a special tube into the pan, where it evaporates. But over time, this process is disrupted due to:

• 🍂 Crumbs and food particlesthat get into the tube during careless cleaning or storage of open products.
• 🧊 Ice plugsthat are formed if the refrigerator has not been defrosted for a long time or the door is not closed tightly.
• 🦠 Mold and mucus —an ideal environment for bacteria is created in a warm and moist tube.
• 🧹 Dust and dirtthat accumulate over time even with regular cleaning.

In models Samsung RB and RL the tube becomes clogged more often due to design features: it has bends where debris gets stuck more easily. And in refrigerators with the CoolSelect Zone+ function, the problem may be aggravated due to additional condensation from the freshness zone.

⚠️ Attention! If the blockage is accompanied by an error 22E or 25E on the display, this is a signal of a malfunction of the defrosting system. In this case, cleaning the tube may not help; diagnostics of the sensors will be required.

Signs of a clogged drain tube

The problem is not always obvious at first glance. Here are the key symptoms that will help identify it:

If you observe at least two of these signs, it’s time to clean the tube. In models Samsung RS5*** with a system Twin Cooling Plus clogging can also manifest itself as uneven cooling between the upper and lower chambers.

Preparing for cleaning: tools and safety precautions

Before you begin, make sure you have everything you need. To clean the tube you will need: Samsung No Frost you will need:

• 🔧 Plastic straw (can be used from a dropper or a cocktail straw).
• 🧴 Pipe cleaning spray (for example, Deboucher or Mole) or a solution of soda and vinegar.
• 🧻 Absorbent wipes or rags - for collecting water.
• 🔦 Flashlight —to inspect the tube from the inside.
• 🧤 Gloves —protection from bacteria and chemicals.

Also prepare the refrigerator:

1. Turn it off from the mains (pull the plug out of the socket!).
2. Remove all products and shelves - you need free access to the back wall.
3. If there is water at the bottom, remove it with a sponge.

⚠️ Attention! Do not use metal objects (wire, knitting needles) to clean the tube - they can damage the plastic or pierce it. In models Samsung RF23*** the tube is especially thin and vulnerable.

Step-by-step instructions: how to clean the pipe

The process of cleaning the drainage tube in Samsung No Frost can be divided into 3 stages: mechanical cleaning, rinsing and checking. Follow the instructions strictly in order.

1. Mechanical cleaning

The tube is located at the back of the refrigerator, behind the protective panel (in some models, under the vegetable drawer). Carefully:

1. Remove the back cover in the refrigerator compartment (usually it is secured with latches or screws).
2. Find the hole in the tube - it is located under the evaporator (a plastic or rubber tube with a diameter of ~1 cm).
3. Insert a plastic tube into it tube/straw and slowly scroll to push through the blockage.

If the blockage is dense, you can use a syringe with warm water - create pressure to dislodge the plug. In models Samsung RL44*** the tube has a bend - be careful not to break it.

2. Washing with chemicals

After mechanical cleaning, the tube must be disinfected:

1. Pour into the hole a solution of soda and vinegar (2 tablespoons of soda + 100 ml of vinegar per 500 ml of water) or a special product for pipes.
2. Leave for 15-20 minutes, then rinse with warm water (1-2 liters) using a syringe.
3. Repeat rinsing with clean water to remove any remaining product.

In Samsung refrigerators with the BioShield system The antibacterial coating of the tube can be damaged by aggressive chemicals. Use only mild products (for example, citric acid solution).

3. Checking the result

Make sure that water flows freely into the pan:

1. Pour a glass of water into the drainage hole (it is located on the back wall of the chamber, under the evaporator).
2. See how quickly the water disappears. If it goes away in 5-10 seconds, the tube is clean.
3. Wipe all surfaces dry and turn on the refrigerator.

If the water stands still or drains too slowly, the blockage has not been eliminated. In this case, you may need disassembling the rear panel to access the bottom of the tube (this is more difficult, and it is better to entrust it to a specialist).

What not to do when cleaning the tube

Some actions may aggravate the problem or damage the refrigerator. Avoid these mistakes:

• ❌ Use boiling water — the plastic of the tube can be deformed, especially in models with thin walls (for example, Samsung RR39***).
• ❌ Use sharp objects (knives, screwdrivers) - risk of puncturing the tube or damaging the evaporator.
• ❌ Pour in undiluted chemicals —aggressive agents (for example, Mole in their pure form) corrode plastic and rubber seals.
• ❌ Ignore errors on the display —if after cleaning error remains 22E, the problem is not in the tube, but in the defrosting system.

Also not worth it turn on the refrigerator immediately after washing —let it stand for 30-60 minutes so that the moisture evaporates from the electronic components In models. with a display (Samsung Family Hub), water getting on the board can cause a short circuit.

Prevention of blockages: how to avoid repeated problems

To prevent the drain tube from becoming clogged again, follow these advice:

• 🧊 Defrost the refrigerator once every 6-12 months, even if it is No Frost. Turn on the mode Vacation (if available) or simply unplug for 24 hours.
• 🍎 Store food in containers - this will prevent crumbs and food particles from getting in into the tube.
• 🧽 Wash the refrigerator inside at least once a month with a weak solution of soda (1 tablespoon per liter of water).
• 🔍 Check the seal —if the rubber band is worn out, warm air enters the chamber and condensation becomes more.

In refrigerators Samsung with the function Auto Defrost (automatic defrosting), blockages are less common, but are still possible if your model is equipped with water filter (For example, Samsung RS62R5001M9), change it every 6 months - this will reduce the load on the drainage system.

What to do if the tube is constantly clogged?

If blockages recur more than once every 3 months, the problem may be:

- Faulty defrosting heating element (the ice does not melt completely, and the tube becomes clogged with ice).

- Damaged seal doors (the constant flow of warm air increases condensation).

- Improper slope of the tube (water does not flow by gravity into the pan).

In these cases, professional diagnostics are needed.

When to call a technician: signs of serious malfunctions

Not all problems with the drainage tube can be solved yourself. Contact the service center if:

• 🔧 The tube is clean, but water still accumulates in the refrigerator compartment.
• ❄️ A thick layer of ice (more than 1 cm thick) forms on the back wall of the freezer.
• 🔌 The refrigerator shows errors 22E, 25E or 28E even after cleaning.
• 💨 The fan No Frost does not work (no air noise when the door is open).

In models Samsung with a system Digital Inverter Compressor (for example, Samsung RB37J5230SS), a drainage malfunction can lead to overheating of the compressor. If after cleaning the refrigerator begins to operate louder or longer, this is a cause for concern.

⚠️ Attention! Warranty. refrigerators Samsung usually does not cover damage caused by DIY repairs. If your refrigerator is under warranty, first consult an authorized service center.
