Owners of household appliances Ariston they often encounter a situation where water appears inside the refrigerator compartment or on the floor in front of it. In most cases, the source of the problem is not a compressor malfunction or freon leak, but a simple blockage in the condensate drainage system. Understanding where this unit is located and how it functions allows you to solve 90% of problems with high humidity without calling a specialist.
Drainage hole is a key element of the system No Frost or drip defrosting, through which moisture is removed from the internal volume of the unit. If this channel becomes clogged with crumbs, ice or mucus, the water has nowhere to go and begins to pool on the shelves or leak out. In this article we will analyze in detail the design of the drainage system of Ariston refrigerators and methods of its maintenance.
Timely cleaning of the channel extends the life of the device and prevents the appearance of unpleasant odors or mold. Regular care drain channel takes only a few minutes, but eliminates serious consequences, such as corrosion of internal panels or spoilage of products due to excess humidity in the chamber.
Principle of operation of the moisture removal system
B refrigerators Ariston, as in most modern models, the process of condensation formation is a natural physical phenomenon. The warm air that enters when the door is opened is cooled, and the moisture it contains settles on the back wall. In models with a drip defrosting system, water flows down through the grooves, falling into a special hole.
Next, the liquid flows through the tube into a container located above the compressor, where it safely evaporates under the influence of the heat of the running motor. If drainage channel functions correctly, the user may not notice this process at all. However, if air circulation is disrupted or the channel is contaminated, the water begins to stagnate.
In systems No Frost moisture is removed during automatic defrosting cycles of the evaporator. The ice melts, turns into water and must escape through the same hole. If you see a puddle under the vegetable drawers, this is a sure sign that drainage system requires your intervention and cleaning.
⚠️ Attention: The constant presence of water at the bottom of the refrigerator compartment can lead to a short circuit of electrical components or damage to the floor covering. Do not ignore the first signs of a blockage.
Where to look for the drain hole in different models
The search for a drain depends on the specific series of your refrigerator Ariston. In classic models with a frosted rear wall, the hole is located at the very bottom of the rear panel, often hidden behind a decorative grille or plastic casing. It is a small round hole with a diameter of about 1 cm.
In more modern modifications, access to drainage channel may be difficult due to the presence of additional elements. Sometimes you need to remove the bottom shelf or pull out the vegetable drawers to get a full view of the back wall. In some cases, the plastic plug may be painted the color of the inner chamber, which makes it less noticeable.
If you cannot find the hole visually, focus on the place where the water accumulates. Water always flows along the path of least resistance and collects at the lowest point where it should flow. This is where the entrance to the drain tube is located.
Causes blockages and their signs
The main reason for blocking the outflow of water is the human factor and natural pollution. Bread crumbs, packaging particles, seeds or pieces of food that accidentally fall towards the back wall accumulate over time and form a dense plug. Dust that gets inside when doors are frequently opened also plays a role.
Another common problem is the formation of an ice jam. This happens if the refrigerator operates in high mode or the door seal is broken. The moisture does not have time to evaporate and freezes right at the entrance to drainage tube, blocking the passage completely.
The problem can be identified by a number of characteristic signs:
- 💧 Water accumulates on the bottom shelf or flows out onto floor when opening the door.
- ❄️ On the back wall, a layer of ice or a “fur coat” is visible in the lower part, even in drip defrosting mode.
- 🦠 The appearance of an unpleasant musty smell, indicating decay of organic matter in stagnant water.
- 💦 Increased humidity inside the chamber, which causes food to deteriorate faster.
Ignoring these symptoms leads to water starting to overflow over the edge of the pan and onto the electrical parts or housing. Clogged drainage this is not just an inconvenience, but a signal of the need for maintenance.
Why does mucus appear in the drainage?
Over time, a biofilm of bacteria and mold that feed on food microparticles forms inside the tube. This mucus has a jelly-like structure and very effectively clogs a narrow channel, preventing the flow of water even in the absence of solid plugs.
Tools and preparation for cleaning
Before starting work, you need to prepare a minimum set of tools. You don't need complex equipment, just items that can be found in every home. The main thing is to act carefully so as not to damage the plastic elements of the internal chamber of the refrigerator Ariston.
For effective cleaning you will need:
- 🧹 A bottle brush or a soft wire with a bent end (for mechanical removal of blockages).
- 💉 A large-volume medical syringe or rubber pear (for washing with water).
- 🧼 Warm soap solution or weak soda solution (for disinfection and dissolving fat).
- 🔦 Flashlight (for a better view of hard-to-reach places).
It is important to disconnect the refrigerator from the power supply before starting any manipulations, although for simple cleaning drainage is not always critical, but safety rules electrical appliances should not be violated. Let the appliance stand for a while if you plan to defrost the ice plug.
☑️ Preparing to clean the drainage
Step-by-step instructions for clearing the blockage
The cleaning process begins with a visual inspection. Remove any products or shelves that obstruct access to the back wall. If the hole is visible, try to carefully clean it with a brush. Movements should be progressive, without excessive pressure, so as not to pierce the canal wall.
If mechanical cleaning does not help, proceed to flushing. Fill a syringe or bulb with warm water (you can add a small amount of soda) and inject it into the hole under pressure. If the water stands and does not go away, it means the plug is deeper. In this case, you can use a thin wire, but always with a melted or bent end, so as not to damage the plastic pipeline.
After the water begins to drain, rinse the channel several times with clean water to remove any remaining dirt. Make sure that the liquid flows freely into the container under the compressor (usually located at the bottom rear, access to it may require removing the protective panel).
The table below will help determine the cleaning method depending on the type of blockage:
| Type of blockage | Symptoms | Removal method | Required tool |
|---|---|---|---|
| Mechanical (crumbs, debris) | Water is in the hole, solid particles are visible | Mechanical removal | Brush, tweezers, wire |
| Ice plug | Ice is visible, the water does not leave even after defrosting | Defrosting, warm water | Hair dryer (carefully), syringe with warm water |
| Biological (mucus, mold) | Unpleasant odor, cloudy water | Disinfection, washing | Soda solution, chlorhexidine, pear |
| Great film | Water leaves slowly, sticky coating | Degreasing | Warm soap solution |
Prevention and frequency of maintenance
To prevent the problem with the drainage hole in the refrigerator Ariston from returning, it is important to follow simple operating rules. Do not place hot foods inside the chamber and ensure that the packaging of liquids is intact. Regular cleaning of the interior will prevent excess debris from reaching the back wall.
It is recommended to carry out a preventive drainage check every 3-4 months. This will take no more than 5 minutes, but will avoid major troubles. Just drop a little water into the hole and make sure it goes away quickly. If the speed has decreased, it’s time to act.
Also monitor the temperature. Too low a temperature can cause ice to quickly form in the duct, especially if the refrigerator is underloaded or, conversely, overloaded, which disrupts air circulation. Optimal setting of the thermostat ensures a balance between cooling and operation of the moisture removal system.
⚠️ Attention: Do not use sharp metal objects (knives, knitting needles) to clean the drainage. You can easily damage the thin walls of the tube or pierce the evaporator, which will lead to expensive repairs with refilling with freon.
Frequent maintenance errors
When trying to solve the problem on their own, users often make mistakes that aggravate the situation. For example, using aggressive chemicals to clean pipes can damage the plastic of the inner chamber or rubber seals. Chemical reactors may react with the materials of the refrigerator.
Another mistake is ignoring the tilt level of the refrigerator. If the appliance is not level, water may not flow into the drainage hole, but may overflow the edge of the tray. Check the legs of the refrigerator and, if necessary, adjust them to ensure the correct slope of the body back.
Some users try to blow out the drain with their mouth or a compressor, which can drive infection or dirt deeper into the system, or splash the contents of the tube throughout the inside of the chamber. Mechanical cleaning and flushing with water are the safest and most effective methods.
Is it possible to use mole or other pipe cleaners?
It is strictly not recommended. Aggressive alkalis can corrode plastic, damage rubber connections and cause corrosion of metal parts of the evaporator. Use only safe household products: soda, soap solution or special sprays for cleaning refrigerators.
Why does the drainage hole freeze?
This happens due to a violation of the temperature regime, frequent opening of the door, a malfunction of the defrost sensor or wear of the door seal. The moisture does not have time to drain and freezes, forming an ice plug.
How often do you need to defrost an Ariston refrigerator?
Models with the system No Frost do not require manual defrosting, but preventive cleaning is recommended once a year. It is advisable to defrost models with a drip system completely 1-2 times a year to remove ice and clean the drainage.
What to do if after cleaning the water still remains?
If washing did not help, perhaps the blockage is deep in the tube going to the compressor, or the tube itself is pinched. In this case, it may be necessary to dismantle the rear panel of the refrigerator to access the drain hose.
