The accumulation of moisture inside the refrigeration chamber LG is not just a minor inconvenience, but a signal that the condensate drainage system requires your intervention. Owners often encounter a situation where water begins to collect at the bottom of the chamber or under vegetable boxes, which can lead to food spoilage and an unpleasant odor. Understanding how to drain water from a refrigerator correctly is a basic skill for keeping equipment in working condition for many years.
The process of removing liquid depends on the type of your model: system No Frost or drip defrosting. In the first case, water usually accumulates in the compressor pan or clogs the drainage channel, in the second, the condensate collector may overflow. Ignoring the problem often leads to freezing of internal components and increased load on the compressor, so you need to act quickly and competently.
In this article we will analyze in detail the action algorithms for various situations, from planned defrosting to emergency cleaning of a clogged drain. You'll learn what tools you'll need, how to safely remove ice plugs, and why it's important to watch the angle of your unit. Proper care of refrigeration equipment minimizes the risk of sudden breakdowns.
Preparation for the water draining procedure
Before starting any manipulations, it is necessary to prepare the workspace and protect yourself from electric shock. Disconnection from the network is the first and mandatory action that cannot be ignored under any circumstances. Even if the water is far from the electrical contacts, the risk of a short circuit due to careless handling of the liquid is too great.
Empty the refrigerator compartment of food. If it’s winter outside, you can take them out to the balcony, otherwise prepare cooler bags or thermal bags with refrigerants. You will also need to remove all removable elements: shelves, drawers, egg trays and bottle holders. This will provide free access to the bottom of the chamber and the drainage hole.
Prepare in advance the necessary equipment for collecting and removing moisture. You will need:
- 🧽 Sponges and soft microfiber rags to absorb residual moisture.
- 🪣 A container with low sides to collect the bulk of the water.
- 💧 A syringe without a needle or a rubber bulb for pumping water out of hard-to-reach areas places.
- 🧣 Rags or old towels that can be laid on the floor in front of the refrigerator.
⚠️ Attention: Never use sharp metal objects (knives, screwdrivers) to pick the ice inside the chamber. This can lead to damage to the evaporator and leakage of freon, which will make repairs economically unfeasible.
Drainage features in models with No Frost
Refrigerators LG with the system No Frost are designed so that moisture should not stagnate inside the chamber in the form puddle Condensate flows through grooves into a drainage hole located on the rear wall and evaporates in a tray above the compressor. If you see water on the floor inside the chamber or under the drawers, the drainage channel is clogged with ice or debris.
To access the drainage hole, on some models you may need to remove the bottom panel of the back wall or remove the bottom vegetable drawer. Visually inspect the hole: if it is covered with ice, careful defrosting will be required. You cannot pour hot water directly onto the plastic - it can crack due to temperature changes.
Why does water appear in No Frost?
In No Frost systems, water appears when the drainage heater fails or the channel becomes clogged. The ice plug prevents the melt water from going into the tray, and it overflows over the edge of the groove directly onto the refrigerator shelf.>
To defrost the channel, you can use an enema with warm (not boiling water!) water. Fill up the water and carefully squirt it into the hole, watching where it goes. If the water stands and does not go away, it means the plug is deep. In this case, using a thin flexible cable or a special brush helps, but you need to act extremely carefully so as not to pierce the channel.
Often the cause of blockage is not only ice, but also food crumbs or mold. After the water begins to drain, it is recommended to clean the channel with a soda solution or a special refrigerator cleaner. This will remove mucus that could cause blockages again in the future.
Defrosting the drip system (crying wall)
In models with a “crying” back wall, the process of condensation and drainage of water occurs constantly while the compressor is running. If you find a puddle at the bottom, this may mean that the drain hole is clogged, or the temperature in the chamber was set too low, causing the water to freeze faster than it drained.
The drainage procedure in such models often comes down to completely defrosting the unit. Leave the refrigerator doors open for at least 12 to 24 hours. During this time, all the ice accumulated on the evaporator and in the drainage system will melt and flow into the pan. It is not recommended to speed up the process with a hairdryer, as sudden heating can damage seals and plastic parts.
After complete defrosting, wipe all surfaces dry. Pay special attention to the area around the drainage hole. If it is clean, but there is still water, check the angle of the refrigerator. The front part of the unit should be slightly higher than the back so that the water flows by gravity into the drainage and does not flow out.
To check the cleanliness of the channel, you can use the following method:
- 🚿 Pour some warm water from a syringe into the hole.
- 👀 Listen to how the water flows into the pan (there should be a characteristic gurgling sound is heard).
- 🧪 If the water is standing still, repeat the procedure with a larger volume of warm water.
- 🌬️ Try to carefully blow out the channel (if there is access from both sides), but do not create excess pressure.
Cleaning the drain pan and channel
The drain pan in refrigerators LG is located above the compressor in the lower rear part of the device. In normal mode, water evaporates from it due to the heat of the running motor. However, if the evaporation system is broken or a “porridge” of dirt and mucus has formed in the pan, water can overfill the container and spill out onto the floor.
To access the pan, you need to move the refrigerator and remove the rear protective panel (if there is one) or simply look into the niche above the compressor. You need to remove the pan carefully, as it may contain hot water and dirt. Rinse it thoroughly with warm water and detergent, removing all plaque.
| Element | Check frequency | Signs of contamination | Cleaning method |
|---|---|---|---|
| Drainage hole | Once every 3-4 months | Water stands in the groove | Rinsing with a syringe |
| Drainage tray | Once a year | Unpleasant odor, mucus | Removal and washing |
| Seals | Monthly | Cracks, loose fit | Wipe, lubrication |
| Rear wall | When defrosting | Ice, drops of water | Wipe dry |
If the pan is intact, but the water does not evaporate, it may be faulty The evaporator heating element (in models with complete No Frost) or the compressor operates in too short a cycle, not having time to heat the pan. In such cases, simple cleaning will not help, you will need diagnostics of the electrical part of the refrigerator.
⚠️ Attention: When removing the pan, be careful with the compressor tubes. They can be hot or, conversely, very cold immediately after work, and also fragile. Do not use excessive force.
Removing ice jams in the system
Ice plug is the most common reason that water does not drain from the refrigerator. It is formed in the bends of the drainage tube hidden inside the housing. It is mechanically difficult to get to them, so the main method of struggle is thermal.
The safest way is to let the refrigerator stand in the off state with the doors open for a day. If you don't have time, you can try heating the drainage hole with a hairdryer. Turn on the hairdryer to the minimum temperature and heat the hole for 2-3 minutes, then try to blow it out or rinse it with water.
☑️ Algorithm for dealing with the traffic jam
There is a method of using a flexible wire. Take a thin insulated wire (for example, from an LED garland) and carefully insert it into the drainage hole. Movements should be progressive, without sudden jerks. The goal is to crumble the ice chips so that the water can pass further.
After removing the plug, be sure to check whether the water goes into the pan. To do this, pour about 50–100 ml of water into the groove on the back wall. If the water quickly disappears and a characteristic sound of flowing appears at the bottom of the refrigerator, it means that the system is functioning normally.
Prevention of ice and moisture formation
So that the question “how to drain the water” does not arise before you too often, it is important to follow the rules for operating the refrigerator LG. The main reason for excess ice is a violation of the temperature regime and tightness. Make sure that the door closes tightly and that the seal is clean and elastic.
Do not place hot or warm food in the chamber. The evaporation of moisture from them creates excess condensation, which the drainage system may not be able to cope with, especially in the summer. Also, do not pack the refrigerator too tightly with food - air should circulate freely.
Check the temperature settings regularly. For the refrigerator compartment, the optimal value is considered to be from +3 to +5 °C. Colder temperatures cause condensation in the drainage channel to quickly freeze before it has a chance to drain.
If you notice that water begins to reappear a short time after cleaning, this may indicate a more serious problem, such as a misaligned refrigerator or faulty sensors. In this case, it is better to contact an authorized service center.
Why does water flow out and not into the pan?
Most often this happens due to the incorrect tilt of the refrigerator. If the front feet are adjusted too low (or the back feet too high), water flows forward toward the door rather than back toward the drain hole. Also, the cause may be an overfilled or misaligned tray.
Is it possible to use boiling water for defrosting?
It is not recommended to use boiling water, as a sharp temperature change can lead to cracks in the plastic case or drainage tube. It is better to use warm water (about 50-60 °C) or let the ice melt naturally.
How often do you need to completely defrost an LG refrigerator?
Models with the No Frost system do not require frequent defrosting; it is enough to do this once a year for hygienic cleaning. Models with a drip system (crying wall) are recommended to be completely defrosted every 6 months.
What to do if the refrigerator does not freeze after draining the water?
If, after defrosting and turning on, the refrigerator does not start to freeze within 2-3 hours, the system may have been damaged during cleaning or the thermostat has failed. Check whether the compressor operation indicator is on and listen to whether the motor starts.
