Controlling the foam level in a washing machine

Modern washing machines contain so many functions and programs that it's sometimes simply impossible to master them all. Moreover, some of them aren't actually very useful, serving merely as a means of attracting attention and boosting sales. However, the foam control feature in a washing machine is quite useful, and below you'll find out why.

What effect is achieved?

When the detergent's active action begins, a large amount of foam is produced. This foam interacts with the fabric fibers and removes stains. However, if you overdo it with detergent or add hand-washing detergent, the foam will begin to form in enormous quantities, and without proper foam control, the machine will not be able to properly wash and rinse out any remaining detergent from the fabric. With the foam control feature, you can rest assured: no matter how much detergent you add, it will be completely removed without any excess, as the machine will automatically pump out any excess from the tank using a special pump.

If the foam buildup reaches such a level that it begins to spill outside the drum, threatening to contact the door lock or other components, the machine will immediately stop the wash cycle. A foam level sensor located at the top of the drum alerts you when the foam level has exceeded a critical point.

Why is this system very useful?

There are several reasons that can contribute to excessive foam formation in the washing machine drum.

1. Using too much detergent. Many users intuitively believe that the more detergent they add, the better the wash results will be. In reality, this isn't true. Modern washing machines clean clothes perfectly with just a small amount of detergent, but excess detergent can remain in the fabric fibers or even settle on other parts of the washing machine, which is detrimental to the machine.
2. Using hand-wash detergent. When washing by hand, controlling the foam level is not important, so hand-wash detergents do not contain antifoaming agents, and their use is harmful to washing machines.
3. Using bleaches, such as "Belizna." Although bleaches are not contraindicated for washing, it is important to carefully follow the instructions and dosage.
4. Wash porous and fluffy items with the usual amount of powder. The porous structure of sweaters, curtains, and down jackets promotes increased foam formation, so the usual amount of product should be halved. Many people ignore this instruction due to ignorance.
5. Certain types of malfunctions in washing machines. For example, if the drain hose fails, the drain or filter becomes clogged, more foam will form.

Important! Excess foam in the drum isn't just an annoying problem, as it might seem at first glance. In fact, it can lead to a short circuit or even complete failure of the entire washing machine.

To prevent this from happening, the foam control feature is there. Even if you add too much detergent, use the wrong type of detergent, or wash porous items with too much detergent, nothing bad will happen; the machine will either pump out the foam or pause completely.
