What is the spin class in washing machines?
Modern washing machines have a large number of functions, which greatly facilitates their use and gives more opportunities. Choosing a new household appliance, it is worth paying attention not so much to a variety of options, as to the useful characteristics of the device itself. The most important component is the spin class, which determines the percentage of moisture remaining at the end of the cycle.
Indicators of dryness are not the last important values. Thanks to the high spin class increases the efficiency of technology, which allows you to cope with the work faster, while saving electricity and water.
To buy appliances with the highest spin performance, you should pay attention to the marking. In the passport of household appliances there are letter designations of different spin class options. There is a well-established classification, which is respected by all manufacturers, because there will be no need to find out what this or that symbol means on different models of washing machines.
Relationship between spin class and power consumption
Power consumption is considered the most important factor when choosing a washing machine. After all, the cost of maintenance and operation of the washing machine depends on this parameter. Nevertheless, the excessive consumption of electricity will have to be reconciled with if the output is required to obtain the driest possible laundry. That is, the higher spin class of washing machines is associated with increased energy consumption.
Nowadays, additional subclasses have been developed, such as A, A, A. They do not depend on the spinning classification, but only indicate the economy of the model in question. In any case, the most efficient and productive machine becomes not only more expensive in itself, but the operation will also be expensive. If the future costs are not frightening, you can safely choose units with high performance indicators.
Spin classes in washing machines: what is it, its features and characteristics, expert advice on choosing high-quality and reliable equipment for the home
Buying a washing machine is a complex and costly task that should be treated with a high level of responsibility. Before you go to a specialized store, be sure to familiarize yourself with all the characteristics of the equipment. One of the main (and most important) characteristics is the spin. This article provides all the detailed information about spin classes, their characteristics and features. With its help, every homeowner will be able to independently purchase a quality and reliable product, both domestic and imported.
The higher the washing class, the better the washing machine will remove dirt from things. Of course, each type of dirt on the same machine will be washed differently. This is influenced by the origin of the stains, the quality of the powder used, and the type of fabric. Therefore, the class of washing machines is assigned after passing their tests under the same conditions. Tests are conducted by comparing the quality of washing of the tested machine with a reference machine for 60 minutes in water heated to 60 C, on the same fabrics with the same dirt and the same detergent. Then a washed piece of fabric on the tested washing machine is compared to the same rag from the reference machine. The results are used to assign a washing class.
Each class has its own performance index, which shows how the fabric washed by the tested machine in relation to the fabric from the reference washing machine.
|1,03||1 to 1.3||from 0,97||from 0,94 to 0,97||0.91 to 0.94||0.88 to 0.91||less than 0.88|
It is worth noting that the cost of the machine does not always depend on the washing class. The price can sometimes be influenced by the brand promotion. So, a washing machine of a well-known brand of class B may cost the same as a machine of less advertised, but class A.
What is the spin class of a washing machine and what they are
Reading the rather extensive technical specifications of modern units, everyone involuntarily has a question: spin efficiency class. what is it and what does it “eat” with. This term refers to the amount of residual moisture in the washed and already wrung clothes. That is. the higher the class of such an indicator as washing efficiency, the faster the machine drum rotates when wringing the laundry, and the things are less wet at the output.
This criterion is assigned to household appliances as a result of certain calculations during the test of the appliance. The items are weighed before and after wet cleaning and the second result is divided by the first value, so the spin class is calculated and indicated what spin type the item belongs to.
The most commonly used is the euro standard, which is expressed in Latin letters. In this gradation, the most productive is the washing class “A”, and the least effective is “G”. To understand all this in detail, pay attention to the transcription according to the international classification of the European Union, presented in the table below.
|spin class||The percentage of moisture remaining after spinning||Spin speed|
|A||45% max||from 1600 rpm./min.|
|B||45 to 54%||1400 rpm./minute.|
|C||54 to 63%||1200 rpm./min.|
|D||63 to 72%||1000 rpm./min.|
|E||72 to 81%||800 rpm./min.|
|F||81 to 90%||600 rpm./min.|
|G||90% and more||400 rpm./min.|
Overview of popular models
There are many models on the market with different functions and classifications. There are also enough manufacturers, from established brands, to new progressive young brands:
- ATLANT CMA 60C102-010 washing machine has energy-saving class A, it has 15 washing programs and low price. from 18000
- CANDY 1411THN3/1-S. It has 11 programs, efficiency A. Consumes 1 kWh per wash cycle. Cost. from 32000
- Modern AEG L8FEC68SR, type A.One of the leaders on the market. Has 11 programs and power consumption of 0.5 kWh per program. Price is high. from 66000
Which variant to choose
Now, knowing what the spin class is, we should still decide which one is preferable, because not always more is better. It is quite obvious that the most noticeable difference will be between 400 and 800 revolutions per minute of the drum. As in the first case, you will almost completely get wet things, and in the second case, the percentage of moisture in them will be much less. about 75%.
Spin speed of 1000 spins will give an indication of about 65% moisture in the washed clothes, which is almost identical to the humidity in the apartment. The results of spinning at higher spin speeds will be obviously seen only on solid fabrics and outer garments.
According to the above indicators and based on the reviews, we can conclude that most often in practice the spin speed of no more than 1000-1200 revolutions per minute is used. So, to overpay for exorbitant 1600-2000 spin speeds./min. does not make sense. Especially since often such high revolutions can not only not bring any visible difference, but also deform and damage your favorite clothes made of more delicate fabrics, which will not be quite pleasant.
Tip: If you are a proponent of drying laundry outdoors, do not overpay for useless features and when choosing a washing machine, give preference to models with a lower spin class.

If you study the washing machine’s user manual carefully, you will find the letters for the spin class. For identification of classes adopted the letters of the English (Latin) alphabet from A to G. The first indicates the highest level and the second, respectively, the lowest. There are also intermediate values, they are marked with “”. The more pluses beside the number, the better. This classification is adopted throughout the world, so no matter where your “home assistant” is produced, the designations will be the same.
Spin class depends on how fast the drum of the washing machine, and how hard it spins things. In general this parameter can range from 400 to 1800 rpm.
If you have lost the product data sheet, you can calculate the spin class yourself. To do this, simply calculate the difference between the weight of things before and after washing and divide the resulting figure by the mass of dry clothes. The result thus obtained must be expressed as a percentage.
The lower the percentage of moisture remaining in the items after spinning, the faster it dries, the higher spin class the washing machine has. Below we show you how much fluid the units of different classes leave in things and what rpm it corresponds to:
- “A”. up to 45%. from 1600 rpm.
- “B”. 46-54%. 1400 rpm.
- “C”. 55-63%. 1200 rpm.
- “D”. 64-72%. 1000 rpm.
- “E”. 73-81%. 800 rpm.
- “F”. 82-90%. 600 rpm.
- “G”. over 90%. 400 rpm.
The calculation clearly shows that the difference between the lower and upper limit is quite significant, while the neighboring figures are not so different. It is worth noting that washing machines of the last two groups are almost no longer produced. Such “dinosaurs” can be found only in thrift or junk stores of household appliances.

Tips for choosing a machine
Those who are going to buy a washing machine can be advised as follows:
- If you intend to dry your clothes on a rope, balcony or patio, buy a machine with a low spin speed.
- If you have heavier clothes to wash, such as jeans or woollens, then a higher spin class would be better.
- Before you buy a technique, you need to make measurements of the room in which you are going to install it, and the place where the machine will be located. On this basis, choose the size of the equipment, as well as the type of loading.
- You need to pay attention to the manufacturer. This largely determines the quality and life of this appliance, as well as the spin class and washing class, since these indicators may differ from each other.
Having taken note of the requirements, which should meet a quality washing machine, you can safely go and buy it. It is already impossible to imagine the life of a modern housewife without this type of household appliances.
