Before buying a washing machine, it is worth evaluating all its qualities. The buyer is most often interested in the capacity of the drum, the number of functions and modes, as well as the energy consumption and spin classes.
Consider what the spin class means and which one is right for you if you are going to purchase a washing machine.
Principles of classification
In most models of washing machines, the number of revolutions that the drum makes when wringing out the laundry can range from 700 to 1700 in 1 minute. You can evaluate the result by the degree of dryness of the laundry – the less moisture remains in the laundry after wringing, the more effective this process is.
To calculate the efficiency at home, you need to do the following:
- Weigh the wrung out laundry.
- Dry things.
- Weigh again.
- Subtract the dry weight from the wet weight.
- Divide what you received by the weight of the already dry laundry.
- Multiply the resulting figure by 100%.
For example, after washing, you weighed the laundry, and you got 5 kg. After drying, the weight of the laundry has decreased to 3 kg. Subtract – we get the number “2”. We divide it by 3 – it turns out 0,66, we multiply it by 100% – we get 66%.
Important! The European standard of spin quality is recognized in the world. It is denoted by the letters of the Latin alphabet. The most efficient class is designated by the first letter of the alphabet – “A” and goes down to the letter “G”.
So, what is the spin class in a washing machine? Consider the decoding of classes, focusing on the international classification of the EU:
- Class “G”. The percentage of moisture after extraction is above 90%. In such washing machines, the laundry at the exit from the drum will be only 10% dry. Revolutions for this class: 400 per minute.
- Class “F” indicates the efficiency of spinning from 81 to 90%. The spin speed is 600 rpm.
- The “E” grade is slightly higher in efficiency, and its standard indicator of moisture content after washing is 72-81. Models pushing on class E operate at 800 rpm for 1 minute.
- Spin class “D” – from 63 to 72%. Speed: 1000 revolutions.
- Spin class “C”: 54-63 percent of laundry moisture. Drum revolutions: 1200 for 1 minute.
- With class “B”, the washing machine wrings out the laundry, leaving no more than 45-54% moisture in it. The machine spins at a speed of 1400 rpm.
- The most demanded class is “A”. After spinning, no more than 45% moisture remains in things. Speed: 1600 rpm
In addition to the number of revolutions of the drum, the type of rotation also affects the spin. Some models have a useful feature that excludes ironing. In such washing machines, the drum rotates in its own way, constantly changing the speed of its rotation – thanks to this, the laundry does not wrinkle, and the iron can be set aside.
How not to make a mistake when choosing
Knowing what the spin class in washing machines is, I want to understand which one is better.
In practice, users turned out that spinning at more than 1000 drum revolutions is rarely used, so it’s not worth buying washing machines with exorbitant numbers of 1600 or 1800.
But the differences between 400 and 800 are significant. In the first case, you will get things with a moisture percentage of about 90%, and in the second, there will be much less moisture, already 75%. Spinning at 1000 revolutions will give a result of 65% moisture in the washed laundry. The last indicator is the most successful. If you compare it with the humidity in your apartment, then the indicators are almost identical.
Attention. Often machines designed for extremely high speeds are much more expensive than slower models. In practice, you will hardly notice any difference in the dryness of the laundry after spinning at 1 and 1,5 thousand revolutions in 1 minute. The difference will be clearly visible only on thick and heavy clothing, for example, outerwear – coats and jackets.
Often too high speeds can negatively affect clothes – they wrinkle, wear out, become dull and thin. When choosing SMA, focus not on the number of revolutions, but on its quality.
Tips for future owners
- Masters servicing washing machines are advised to give preference to imported SM assembly. China and Korea are also imports, but they are significantly inferior in build quality to Italy or Japan.
- In addition to the spin class in washing machines, it is worth taking a closer look at such a parameter as the energy consumption class. Sometimes, with the same quality of washing, some machines consume little energy, and the second – 2-3 more. Opt for economical models: A, A+ and A++.
- Often, buyers associate the quality of such a parameter as spinning with the type of CMA load. Also in stores they assure that vertical machines are more reliable. But not a single machine can vibrate during the spin cycle like “verticals”. Front-loading machines, despite the one-sided mounting of the drum, shake and stagger much less.
