Functions and operating principle of an air bubble washing machine. Repair of Daewoo washing machine

No matter how trivial it may sound, washing machines have become an integral part of every person’s life. They make life much easier, save time and effort, and also improve the quality of washing. With the development of technology, the quality and functionality of the device itself improves. Not long ago, air bubble washing machines appeared. What are they? What is their advantage over other models?

Operating principle and classification system

Let's look at how washing machines of this type work. The principle of their operation is based on the ability of air bubbles to affect the laundry being washed. Bubbles are formed from holes that are located in large numbers in the drum. Getting into the fabric, they intensively dissolve the detergent and “expel” dirt from the fibers.

There are two types of air bubble washing machines: activator and automatic.

Activator devices have been known for many years, but they have never become popular among consumers. And this is despite the fact that devices of this type have some functions of an automatic machine. They often perform a spin cycle and also have containers for detergent and rinse aid.

Washing machine

A great example is the Daewoo bubble washing machine. Its main feature is the ability to connect to both cold and hot water. The use of this device increases the efficiency of washing and also improves the cleaning of textiles.

The design of air bubble automatic washing machines is constantly changing. There are fewer of them than classic models. In addition, they have a higher cost.

A few examples

Similar devices are manufactured by many companies. This includes Daewoo, LG, and Bosch. Some of them are designed for 3 kg of laundry, others for 5 and 6 kg. They can be vertical or front loading.

DAEWOO DWF-803WPS

There are several models of bubble washing machines that are especially popular among consumers.

Daewoo DWF-820MPS

The distinctive characteristics of this device are reliability, high quality workmanship and ease of use. Features include vertical loading and an electronic control system. You can wash 6 kg of clothes at a time.

It is noteworthy that this Daewoo car model has a rather attractive appearance and modest dimensions. Thanks to this, it can fit even in a small bathroom.

Daewoo DWF-820MPS

According to the instructions, this Daewoo washing machine has several additional functions:

washing delicate fabrics;
washing down jackets;
express program;
stain removal system.

In Daewoo cars, the tank is made of stainless steel, which significantly extends their service life. Typically, these air bubble devices are painted white, making them easy to fit into any interior. But there are models in bright colors, for example, red.

Air bubble washing machines from Daewoo have other features. For example, the inner surface of the drum is coated with silver particles, which help destroy bacteria. In addition, they are reliably protected from leakage and increased foaming.

Advantages and disadvantages

Bubble washing machines, regardless of the type of loading (vertical or frontal), have a number of advantages and disadvantages. The first include:

High quality wash. They are especially effective when washing heavily soiled laundry, such as kitchen towels.
Opportunity to save. According to reviews, bubble technology allows you to wash even in cool water. Thanks to this, the family spends much less electricity than when working with other types of devices.
Low consumption of detergent. Thanks to the action of bubbles, the washing powder dissolves better. Therefore, you should put it less than usual. By the way, the same powder is suitable for an activator-type device as for automatic ones.
After washing, the laundry retains its original appearance. Thanks to a special washing technology, even woolen items do not shrink or pill, and do not require repairs.
Less wear and tear. Air bubbles create a barrier between the clothes and the drum, which protects items from wear and tear.

Washing machine Daewoo DWF-806MPS

The list of shortcomings looks like this:

To get a lot of bubbles you need soft water.
Automatic washing machines with air-bubble washing technology are large in size.
Devices of this type have a higher price.

Knowing the advantages and disadvantages of these devices will help you make the right choice.

What's in stock?

You can't blame the Koreans for anything but monotony. keeps up with more famous South Korean companies - every year the market is replenished with new models with all sorts of innovations.

Among Daewoo automatic washing machines (AWA):

frontal;
vertical;
and even hanging ones.

Wall-mounted SMA is one of the new products of the Korean company. A mini washing machine washes only a few kilograms of laundry, but takes up minimal space.

The brand’s assortment includes automatic and semi-automatic machines, with and without drying, devices with different loads - from 7 to 15 kg, width from 53 to 58 cm. The price range is also extremely wide; there are SMAs for sale for any budget - from economy options to luxury devices , comparable to a mini-laundry.

Koreans have been producing semi-automatic activator machines for a long time, which were very popular among village residents and summer residents. However, their production has now stopped.

Frequent malfunctions of Daewoo cars

Based on the errors listed above, you can immediately determine the most vulnerable spots of this brand of SMA. Typically, owners of Daewoo washing machines contact workshops with the following problems:

Damage to the electronic board. Failures that confirm a breakdown can be very diverse - from stopping the wash to running the program too long. If your Daewoo washing machine does not spin, this may also indicate an electronic failure.
Level sensor failure.
Water intake filter clogged.
Temperature sensor malfunction. Accompanied by poor heating of the water and stoppage of work in the washing mode.
The drive belt is worn out (often due to a breakdown or manufacturing defect of the pulley).
The heating element fails. Usually due to a large layer of scale or corrosion.
The hatch is leaking due to the rubber seal bursting.

The breakdowns considered are the most typical, and it does not matter what type of Daewoo washing machine you have - with a vertical or horizontal load. These nodes are vulnerable to all types of SM.

Experts also consider the weak points of Deo machines to be the drum, which wears out over the years, rusts, and suffers from too hard water.

What's special about Daewoo?

The company produces real giants - there are machines that can wash 15 kg at a time.
Lots of color options. White is not the only color in the palette of the brand in question. The range includes red, silver, platinum and dark gray cars. There are even devices with prints.
The assortment includes hanging washing machines. In Russia, only Daewoo presents wall-mounted versions.

Technology and Innovation

Interesting solutions, functions, modes, programs and device features:

Bubble wash. Only a few brands use this technology. Things are well cleaned of dirt thanks to air bubbles. Scheme of work:

The water in which the detergent is dissolved is not sent directly to the drum, as in conventional machines, but to the generator.
In the generator, the solution turns into microscopic bubbles. The powder reaches 100% dissolution.
Bubbles stick to fabric fibers. Here, when they burst, they release energy that pushes dirt out of the tissues.
This economical technology works even in the coldest water with a minimum of detergent. Another advantage of bubble washing is that it is gentle on fabrics. The fibers are practically not damaged, and things retain their newness longer.

Star type drum. Thanks to the special drum design, the user receives the following advantages:

The drum is installed at an angle, so loading and unloading laundry is simplified.
The surface of the drum is covered with holes in the shape of 5-pointed stars. The holes are very small in diameter - clothes do not catch on them.

Direct drive. Today, all leading SMA manufacturers use direct-type motors. The advantages of this solution:

machine efficiency increases;
noise during operation is reduced;
working resource increases.

Nano Silver. The material from which the drum is made contains silver. During washing, the laundry is permeated with silver nanoparticles, which are known to have an antibacterial effect. Things not only become clean, but also disinfected.
Dr.Dispenser. This solution will allow you to save detergent - this consumable is not cheap, and you have to spend it regularly and in large quantities. Thanks to a special dispenser, the detergent is dispensed in strictly measured quantities. Another advantage of the dispenser is the ability to refill for 25 cycles. You don't have to add powder before each wash.
Jet rinse. The design of the machine includes special nozzles, thanks to which a 3-stage jet rinse is implemented.
Steam treatment. This function no longer surprises consumers; its presence is becoming almost mandatory for SMA of a decent level. Thanks to steam, it is possible to efficiently wash away dirt and wash away any remaining detergent - this is especially valuable for families with children and allergy sufferers. This technology also significantly reduces the time spent ironing clothes.
Fuzzy Logic Control. Intelligent control that analyzes the process parameter. The system controls the weight of the laundry, temperature, and foam formation. As work progresses, the system makes the necessary adjustments. The user does not have to delve into the intricacies of the process - the device itself takes care of all the nuances.

Thanks to Nano Silver technology, not only underwear is disinfected, but also the SMA itself - mold fungi will never grow in it and no smell will appear.

The latest generation of washing machines is equipped with additional capabilities. All of them are aimed at increasing comfort and safety of operation. These are the functions and technical solutions:

control of the balance of laundry in the drum;
preventing leaks;
foam formation control;
protection from child interference;
delayed start;
hatch opening 180 degrees;
the control panel is located at an angle;
There is an LED display.

What about programs?

The engineering staff of Daewoo, when determining the number of programs for manufactured vehicles, proceeded from practice. In fact, ordinary users do not use more than 4-5 programs. All 15–20 programmed modes are nothing more than a tribute to competition. Daewoo took a different route - the list of modes here is very short. In the most expensive modifications there are no more than 15 of them. But this is more than enough to meet any needs.

Thanks to the built-in programs, you can wash efficiently and carefully:

synthetics;
woolen products;
cotton;
downy things;
items made from delicate fabrics;
sports equipment;
Kids' things.

Also, all SMAs provide washing:

dirty things;
economical;
preliminary;
express;
super rinse.

And only elite class SMAs have some “extra” programs. For example, you can set a special program for blankets, dark clothes, and underwear.

Are there any disadvantages?

Washing machines from Daewoo are not the standard of efficiency. In the presented assortment there are practically no modifications with energy consumption class A+++, and class A++ is a rarity.
There are many “low-speed” versions - 700-800 rpm. But many machines have a drying function - Wind Dry, which compensates for poor-quality spinning.

How much are?

The cheapest versions cost around 10,000 rubles. But at this price only vertical models are offered. The cheapest front camera costs 13,500 rubles. True, such options have the most modest capabilities - a minimum load (6 kg) and low spin speeds (700–800 rpm).

More “advanced” modifications are more seriously equipped, but they also cost twice or three times more. Their arsenal usually includes bubble technology, a 9 kg load and a spin speed of 1200 rpm. Cost - about 20,000 rubles.

The premium class is distinguished by a large load - 12-15 kg, a stylish design, a large list of programs and various innovations that we talked about above - an inclined drum, etc. Elite modifications cost 25,000-40,000 rubles. The most expensive machines are those with drying and cost about 70,000 rubles.

Do-it-yourself repair of the most common Daewoo faults

Below we will clearly look at the instructions with photos and videos on how to proceed if you decide to carry out the repairs yourself.

Checking and replacing the pressure switch (level sensor) in a Daewoo machine

If water does not flow into the machine, or this process is too slow, check the water level sensor. Proceed as follows:

Disconnect the SM from the power supply.
Remove the top panel from the machine body (cover). It is attached to two bolts on the back of the washer.
After unscrewing the bolts, slightly push the panel back, removing it from the machine body.
In many models, the sensor is located on the wall of the SM, not far from the top cover.
Having found the sensor, remove the pipe from it, which is secured with a clamp - to do this, you will need to loosen this clamp, armed with pliers.
Install a new one in place of the old hose. Blow lightly into it.
If the contacts are triggered, you will hear a clicking sound. Their number depends only on how many water levels are provided in your SM.
Inspect the tubes for damage. If required, they need to be replaced. If the tubes are dirty, simply clean them. If the tubes are stuck, then it is worth changing the sensor itself.

Where are they made?

Most consumers associate Daewoo with cars. But the company works simultaneously in many areas, and one of them is household appliances. The production of Daewoo washing machines is established in South Korea, China, and the CIS countries. If you are interested in the country of assembly, inquire about this issue separately - different models, as a rule, are produced in different countries.

Operating principle of the washing unit

As is already clear from the name, this unit removes various types of stains using the circulation of bubbles.
Air bubbles constantly move in the water and pierce things; with the help of washing powders or liquid conditioners, the bubbles wash away contaminated areas.

Something similar to boiling, but if you boil, you will simply ruin your things, because hot water wears out and weakens the fibers.

Types of air bubble washing machines

There are only two types of machines equipped with bubble washing technology. The first option is automatic models, the second is activator. Technological features influence the principle of implementation of bubble washing.

Automatic cars

Such products have the usual horizontal loading. One of the main parts in automatic machines is the tank. After all, water flows into it and things are stored. The stainless steel drum is hidden inside the tank. It is he who will rotate, moving the laundry.

When started, the hose begins to pump water into the tank, and it also fills the detergent tray. The soap solution enters the bubble generator located under the drum. As a result, water and powder combine with air. A mixture of bubbles, foam and soap solution is formed, which enters the drum through the perforations.

The generated bubbles penetrate the tissue, pushing out contaminants. This technology allows you to eliminate any stains, even dried and persistent ones. This is achieved largely due to the heat generated when the bubbles burst.

Many experts consider this process to be similar to boiling. However, exposure to high temperatures can cause items to deteriorate, and bubble technology maintains texture and quality.

Activator machines

The main feature of activator-type machines is vertical loading. The difference between such devices is the absence of a heating element, since they are connected to hot and cold water supplies. The bottom of the drum is equipped with a pulsator that creates vortex flows of water.

Through a special nozzle, the bubbles enter the activator, which is responsible for their uniform distribution. And the generator continues to produce new portions throughout the entire cycle. Effective removal of contaminants occurs due to the supply of bubbles under high pressure.

Features of the Daewoo washing machine range

Wall-mounted

The Daewoo brand regularly replenishes the market with innovative washing machines, including even wall-mounted models. Such machines take up minimal space in the room.

The body depth of this SMA is 29.2 cm, width – 55 cm, height – 60 cm. In addition, the device weighs only 16 kg. The load-bearing wall can easily support this weight even when the machine is full of water and laundry.

The functionality of hanging miniature cars is small. They are capable of washing up to 3 kg of laundry in one working cycle. Most of them are equipped with six washing programs and spin speeds of up to 800 rpm.

Do you wash by hand?

Oh yes! No

The inverter motor makes the device operate almost silently. Other advantages of the mini-automatic machine include:

star drum;

the presence of a mode for washing children's clothes;

convenient containers for detergents.

The sprocket drum is one of Daewoo's innovations. Its surface is covered with tiny holes shaped like stars. Their diameter is quite small, so laundry does not get caught.

Expert opinion

I work in the household appliance repair industry. Extensive experience in restoring washing machines and dishwashers.

Ask a Question

Wall-mounted machines can create a futuristic interior. By the way, in Russia wall-mounted washing machines are represented only by this brand.

Front loading

There are a lot of front-loading machines in the brand's assortment. It is worth noting that in Russia such SMAs are most popular. In the Daewoo model range you can find both compact narrow and full-size options.

Front-loading SMA has a number of advantages:

It is built into pieces of furniture or under the sink.
The surface of the body is used as a shelf.
The washing process can be observed through the hatch.

"Verticals"

Daewoo vertical machines are distinguished by their compactness. In addition, the location of the door at the top limits access to the device for small children.

In models with both vertical and horizontal loading, the manufacturer uses a direct drive, which increases the efficiency and efficiency of the device, as well as reduces the noise level during washing and spinning.

Daewoo makes drums for its equipment from a material that contains silver. Nanoparticles (Nano Silver) have an antibacterial effect, so the laundry is not only cleaned, but also disinfected.

Air bubble

The technology for cleaning things from dirt using air bubbles - Air Bubble - is used by several other manufacturers besides Daewoo. The essence of the method is that soapy water first enters a special generator, where it turns into a mass of tiny bubbles, and only then into a drum with laundry.

This ensures that the detergent is completely dissolved in the water. Air bubbles penetrate the fibers of the fabric and burst, thereby literally pushing out contaminants from the structure of the material. This method is safe for things, since they are not subject to friction.

Experts believe that the effectiveness of such washing does not decrease even in cool water. Therefore, a number of bubble-type models do not have a heating element; the machine is connected directly to the hot water supply.

Model overview

Consumer Reviews

The wall-mounted Daewoo DWD CV703W is really very quiet. I also like the mode for washing children's clothes. Since I always wash my baby’s clothes separately from the rest of my laundry, a 3 kg drum is enough for me. Keep in mind that it is recommended to mount the machine to a load-bearing wall, and it is desirable that it be perfectly level.

Alexandra

Friends dissuaded me from buying the DWC PHU12Y1P. Few people use drying machines yet, but I have never regretted the purchase. The quality of washing and drying is simply excellent. There are many modes of both. Detergent and conditioner are dispensed automatically. The family is large, the car copes with our volumes of dirty laundry with a bang.

Hope

I have been using Daewoo equipment for decades. The quality is decent. I also chose the car consciously based on the manufacturer. Serves reliably without breakdowns.

Nikolai

Daewoo Electronics offers consumers a large selection of washing machines: from miniature wall-mounted ones to capacious premium-class giants. Therefore, finding your own option with the necessary options for any financial opportunity will not be difficult.
