Before you buy a machine, you should first study all the technical characteristics. If you want things to completely get rid of stains, you should pay attention not only to the CMA functionality, but also to the washing class. The main topic of this article is to find an answer to the question – which class of washing in washing machines is better.
Class breakdown: A to G
What does the washing class mean in a washing machine? This designation indicates the degree of effectiveness in removing stains and dirt from laundry. There are such classes:
- A,
- В,
- FROM,
- D,
- E,
- F,
- G.
The definition depends on comparing the coefficient of the certified machine and the indicator of the reference washer. To determine the washing efficiency class, the developers created a special standard for the cleanliness of things. That is, they took a heavily soiled piece of fabric, and then washed it in a certified machine, adding 180 g of detergent, setting the reference program with a cycle of 1 hour. In this case, the temperature regime was equal to 60 °. As a result, a result was obtained, with which a comparison was made. Next, a special table was compiled, according to which the machine receives an appropriate rating. The better the washing machine cleans the soiled fabric, the higher its efficiency.
| Class | Wash quality | Level of quality |
| А | Fine | 1,3 |
| В | Washes very well | 1-1,3 |
| С | Well | 0,97-1 |
| D | Normally | 0,94-0,97 |
| Е | Satisfactory quality | 0,91-0,94 |
| F | Poorly | 0,88-0,91 |
| G | Worse than bad | 0,88-0 |
About the reference SMA
The reference machine saw the light in 1995. Now only authorized manufacturers can afford standards. Their effectiveness is undeniable. But be careful: in view of the rapid development of modern technologies, a conventional machine can wash much better than a reference one. Remember that the benchmark shows a stable result, not the best. She just recorded the lowest variation in performance. That is, 10 out of 10 washes are approximately the same in quality, while not in the reference model for 10 washes, 1-2 will be of low efficiency, and the rest will be with brilliant performance.
Class A – the highest rating
The ideal wash is the one that removes all dirt, even the most difficult stains. Often, models where the class is equal to the value A cope so efficiently and effectively with the removal of spots.
There is an opinion that class A is significantly different from B. But the difference between them is extremely small. Therefore, if economy is at stake, take class B.
What is the difference between class A and class B? The designation A is the highest rating in the table, since the model passed the test wash better. If the machine has the designation B, then it copes with the removal of contaminants a little worse.
Which class is recommended
Most people always ask these questions when they go shopping for a washing machine. And the answer here is quite logical: it is better to choose a model with a high rate. Washing machines with the designation “A” are considered the most profitable, as they wash clothes efficiently, remove dirt and stains, and also save energy. And purchasing a low-end model will result in high power consumption and low efficiency.
Important! How the machine washes and how much energy it consumes also depends on the amount of washing. When the drum is overloaded, the quality of the wash deteriorates, and the technique consumes more energy!
