The noise of water in the refrigerator: gurgling, gurgling, the sound of pouring liquid - what is it and how to fix it

You are standing in the kitchen, and suddenly a strange sound comes from the refrigerator - as if water is pouring or liquid is gurgling somewhere inside. At first it may seem that the equipment is about to fail. But don’t rush to panic: in 80% of cases, such noise is normal operation of the systemand not a sign of a breakdown. However, there are exceptions when the murmur indicates a malfunction that is best eliminated in time.

In this article we will look in detail at why the refrigerator makes the sounds of pouring water, in which cases it is safe, and when it requires the intervention of a technician. You will learn how to distinguish “healthy” noises from alarming ones, what to do for prevention, and when exactly it’s time to call the service center. We will pay special attention to the differences between the systems NoFrost and drip defrosting - they “behave” differently.

For convenience, we have collected all possible reasons in a table, added checklists for self-diagnosis and answers to frequently asked questions. If after reading you still have doubts, use our FAQ block at the end of the article.

1. Why does the refrigerator make sounds of pouring water: main reasons

The noise of water in the refrigerator can occur for several reasons, and most of them are not related to breakdowns. Let's consider the key sources of sounds:

• 💧 Refrigerant circulation —in systems NoFrost freon moves through the tubes, making gurgling sounds, especially when the compressor is turned on.
• ❄️ Ice melting —in drip refrigerators, water flows into the pan during thawing, which is accompanied by gurgling.
• 🔄 Operation of the drainage system — if the drain hole is clogged, water can accumulate and “splash” when moving.
• ⚙️ Fan malfunction —in models with NoFrost the blades can touch the ice, creating the illusion of pouring liquid.
• 🚰 Problems with the water supply system (in refrigerators with a dispenser) - leaks or air in the tubes.

It is important to understand that character of sound says a lot about its nature. For example, short gurgling when the compressor starts, this is normal, but constant gurgling may indicate a clogged drain. Next, we will analyze each case in more detail.

2. Normal noises: when there is no need to worry

If your refrigerator makes sounds of pouring water, but at the same time it operates stably (maintains temperature, there is no puddle at the bottom), most likely it is standard processes. Let's look at the most common “safe” reasons:

2.1. Operation of the NoFrost system

In refrigerators with NoFrost (for example, Samsung RB30J3000WW, LG GA-B489YGQZ) the refrigerant circulates through the tubes under pressure. When the compressor is turned on, the freon begins to move, which is accompanied by:

• 🔊 Gurgling (like boiling water in a kettle).
• 💦 Light hissing (if the system is sealed, but the tubes are close to the body).
• 🌀 Short-term murmur (when changing cooling modes).

These sounds usually last no more than 10–15 seconds and are repeated at intervals of 1-2 hours. They are especially noticeable in quiet models (noise level up to 38 dB).

2.2. Thawing in drip refrigerators

In models with a drip system (for example, ATLANT XM 4021-000, Indesit DF 4180 W) frost forms on the rear wall, which periodically melts. Water flows into the drainage hole and then into the pan above the compressor. This process is accompanied by:

• 💧 The sound of dripping water (like from a low-pressure tap). data-i="101">The sound of dripping water
• 🌊 A slight “splash” (if the pan is full).

Normally, this noise is heard 1-2 times a day and lasts no longer than a minute. If the sound becomes constant, check the drainage (more on this). below).

2.3 Fan operation

In refrigerators. c NoFrost the fan distributes cold air through the chambers. If ice forms on the blades (for example, due to frequent opening of the door), they can touch it, creating the illusion of pouring water. This sound:

• 🔄 Appears when starting the fan (via 5–10 minutes after closing the door).
• 🎵 Reminds russling or slight creaking.
• ❄️ Occurs more often in models with LowFrost (for example, Beko GNE 114620 X).

⚠️ Attention: If the fan sound becomes louder than usual or is accompanied by vibration, check to see if the drain hole in the freezer is clogged. Ice accumulation may cause the blades to freeze.

3. Alarms: when the sound of water is a sign of a breakdown

If the sounds of pouring water are accompanied by other symptoms (poor cooling, puddles under the refrigerator, constant hum), this may indicate a malfunction. Let's consider the main problems:

3.1. Clogged drainage system

One of the most common causes of constant gurgling is clogged drainage hole. Water does not flow into the pan, accumulates at the bottom of the chamber and makes sounds when moving. Signs:

• 💦 Puddles under vegetable boxes.
• 🧊 Ice in the drainage hole (visible upon inspection).
• 🔊 The noise increases when the door is opened.

To fix the problem:

1. Disconnect the refrigerator from the network.
2. Clean the hole with a plastic tube or wire.
3. Rinse the drainage with warm water and soda (1 tablespoon per 1 liter).

3.2. Freon leakage

If gurgling is accompanied by poor cooling (the temperature in the chambers is higher than normal), this is possible. refrigerant leakThis is a serious breakdown that requires specialist intervention. data-i="158">poor cooling

• ❄️ The freezer hardly freezes, and the refrigerator compartment is too warm.
• 🔊 The gurgling sound is constantly heard, even when the compressor is turned off.
• 💨 The compressor runs non-stop.

It is impossible to fix the leak on your own - you need specialist with equipment to refill freon. Average repair cost: from 3,500 to 8,000 ₽ (depending on the model).

⚠️ Attention: If you suspect a freon leak, do not try to “top up” the refrigerator on your own. Refrigerants (for example, R600a or R134a) are toxic and explosive if mishandled.

3.3. Problems with the water supply system (in models with a dispenser)

In refrigerators with a dispenser (for example, Samsung RF23HCEDBSR, LG GR-B207 JVCZ), water noise can be associated with:

• 🚰 Leaking in the pipes (if the connections are loose).
• 💨 Ingress of air into the system (gurgling can be heard when water is drawn in).
• 🔧 Valve malfunction (water drips even when the tap is closed).

For diagnostics:

1. Check whether the pipe connections behind the refrigerator are wet.
2. If water drips from the dispenser without pressing, replace the valve.
3. If there is gurgling in the pipes, bleed the air by draining 1–2 liters of water.

4. How to diagnose the problem yourself

Before calling a technician, go through this algorithm to understand what exactly is wrong with your refrigerator:

Step-by-step instructions for models with NoFrost

1. Unplug the refrigerator for 1 minute, then turn it on again. Listen to see if the noise has changed.

2. Open the freezer and shine a flashlight on the fan (usually located in the back). If there is ice on the blades, defrosting is needed.

3. Check if the error indicator is lit (for example, E1 or F2 on the display). Look for decoding of the code in the instructions for the model.

4. If the noise sounds like splashing, tilt the refrigerator back a little. If the sound intensifies, the problem is in the pan.

For drip refrigerators:

1. Look for ice in the drainage hole (it is located in the center of the rear wall of the refrigerator).
2. Check the pan above the compressor - if it is overfilled, water may “splash” when vibration.
3. Pay attention to the temperature: if the refrigerator does not freeze well and the gurgling is constant, this may be a freon leak.

If after checking you have not found any obvious reasons, but the noise bothers you, record it on your phone and compare it with examples:

• 🔊 Normal gurgling of freon (short, when turned on compressor).
• 💦 The sound of a clogged drain (constant murmur).
• ❄️ The noise of frozen fan (rustle or creaking).

5. Prevention: how to avoid water noise in the refrigerator

To minimize the risk of extraneous sounds, follow these recommendations:

5.1. Correct installation of the refrigerator

• 📏 Flat surface: adjust the legs so that the refrigerator does not rock. Misalignment can lead to the accumulation of water in the pan.
• 🔌 Gap for ventilation: leave at least 5 cm from the wall so that the compressor does not overheat.
• 🌡️ Far from heat sources: do not place near the stove or radiator.

5.2. Caring for the drainage system

Clean the drainage hole every 3-6 months (more often if the refrigerator is often opened). Use:

• 🧼 Soda solution (1 tablespoon per 1 liter of water).
• 🧽 Special brush (sold in household appliance stores).
• 🚫 Do not use sharp objects (risk of damage tube).

5.3. Defrosting and caring for NoFrost

Even refrigerators with NoFrost need defrosting once a year. This prevents the fan and pipes from freezing. How to defrost correctly:

1. Unplug the refrigerator.
2. Take out all the food and shelves.
3. Leave the doors open for 12–24 hours (depending on model).
4. Wipe the internal surfaces with a dry cloth.
5. Before turning on, check if there is any ice left on the fan.

⚠️ Attention: In refrigerators with a system LowFrost (for example, Lieberr EK 3520), it is enough to defrost once every 2 years, but the drainage still needs to be cleaned regularly.

6. When to call a professional: a checklist for making a decision

The sound of water does not always require professional intervention. Here are the cases when required you need the help of a specialist:

• 🔧 Refrigerator does not freeze well, despite cleaning the drainage and defrosting.
• 💧 Under the refrigerator water constantly accumulates, even after cleaning the drain.
• 🔊 Noise is accompanied by vibration or loud hum (problems with the compressor are possible).
• 🚨 Lights up on the display error code (for example, E3, F5).
• ❄️ In the freezer compartment too much ice is formed (even in NoFrost).

If none of these signs are observed, most likely the sound of water is a normal process, and there is no need to worry. However, if in doubt, it is better to play it safe and call a specialist for diagnostics.

FAQ: Frequently asked questions about the noise of water in the refrigerator

❓ Why does the refrigerator gurgle only at night?

At night, the apartment is quieter, so the usual sounds of freon circulation or compressor operation become more noticeable. If during the day the noise is drowned out by household sounds, and at night you hear gurgling, this is normal. Check if the refrigerator is touching the wall or furniture (vibration can increase the sound).

❓ In the refrigerator with NoFrost you can hear the sound of pouring water - this is breakdown?

Not necessary. In systems NoFrost gurgling may be due to:

• Freon circulation (normal).
• Fan operation (if there is some ice on the blades).
• Condensate flowing into the pan (if the sound is short and repeated rarely).

This can only be a breakdown if the noise is constant and the refrigerator does not freeze well.

❓ How to distinguish normal gurgling from a freon leak?

Signs of a leak freon:

• Gurgling is heard constantlyeven when the compressor is turned off.
• Refrigerator does not maintain temperature (foods spoil faster).
• The compressor is running without stopping or turns on too often.

Normal gurgling:

• Short (up to 15 seconds).
• Repeated at intervals of 1–2 hours.
• The refrigerator operates as usual.

❓ Is it possible to repair the drainage drain yourself? hole?

Yes, this is one of the few problems that you can fix yourself. You will need:

• A plastic tube or wire (diameter 3-5 mm).
• Warm water with soda.
• Syringe or syringe for flushing.

Algorithm:

1. Turn off the refrigerator.
2. Find the drainage hole (usually in the center of the back wall of the refrigerator compartment).
3. Clean it wire, then rinse with water.
4. Check whether the water goes into the pan (you can pour a little water into the hole).

If after cleaning the water still does not go away, the blockage may be deeper and you need a technician.

❓ Why did the sound of the water become louder after defrosting?

This may be due to:

• 💧 Accumulation of water in the pan (if the refrigerator does not have time to evaporate it).
• 🌀 Air entering the cooling system (if defrosting was too abrupt).
• ❄️ Formation of condensation on the pipes (if the door has been open for a long time).

Let the refrigerator operate 12–24 hours —if the noise does not disappear, check the drainage or call masters.
