Water hardness affects the operation of the dishwashing machine. On this depends the condition of the internal parts, as well as the quality of the wash. Therefore it is necessary to understand how to get the hardness of the water for the dishwasher. It is necessary to set the correct settings for the quality of the work equipment.
As part of normal tap water contains salts of heavy metals and other chemical compounds. Depending on their amount of water may be considered a soft or hard. The high content of magnesium and calcium indicates its increased rigidity. During the heating process and their salts are destroyed to form a precipitate. This phenomenon is called temporary hardness.
Other substances, such as nitrites and phosphates do not undergo degradation and are in the water all the time. Permanent hardness is determined by their presence.
This factor directly influences the composition of the soil in the region. Almost across the country in the water hardness indices higher.
Because of hard water on the heating elements of household appliances such formed limescale, which degrades performance.
Therefore, water must soften special means. The new models are installed dishwashers ion exchange systemsThat change the chemical composition of the aqueous stream by attracting calcium and magnesium ions. Also, all the time you need to add regenerating salt for dishwashing machines in a dedicated compartment for her.
How to identify
To properly adjust the hardness of the water for the dishwasher you need to know how to determine this figure. This can be done in several ways:
- with test strips;
- special equipment;
- traditional methods.
tests
Test strips are treated with a reagent that when lowered into water shows the degree of rigidity. It can be found in the number of indicators on the strip or to change the color of the tester. Then you need to compare the result with the table in the manual of the dishwasher. Accordingly, it is necessary to expose the settings in the machine.
Technics
You can accurately determine the hardness of tap water with the help of TDS meter. One end of the device on which the sensor should be dipped into the liquid. After that, the unit, the display shows the chemical composition.
Traditional methods
With popular ways to easily identify in hard or soft tap water. If with soaping of hands with soap quickly produces a lot of foam, The content of heavy metals is small. better to use soap, in which at least foam components for the dough.
If in the kettle fast form scale - it also indicates the increased stiffness. Yet check the level can be based on how muddy water will be after thawing.
The latter method is that the water should be poured into a clear glass jar and put in a dark place. If the water is soft - it will remain transparent. And a large gathering of metal salts in the vessel and the liquid will precipitate will look muddy.
These methods give a general idea of the degree of hardness, but do not show the quantitative level, it is necessary to adjust the dishwashing machine. The easiest method to obtain accurate results - test strips. With many modern machines from well-known brands, they are included.
adjustment
After determining the index using the test strip is necessary to start the machine and configure it. To set the hardness level you want to use the program select function. The sequence of actions in a particular model is described in the instruction manual.
The company Beko devices switch settings by pressing buttons marked with + or -. After setting the desired parameter save it by pressing the Start button. To change the index would have to reset the settings applied to reset the values.
There are special filters that reduce the metal content in the water flow. Also, do not forget to use regenerating salt. It should be in the compartment of the device permanently. To this end, it provides the function of determining its level - when the compartment is empty, the machine alerts the user indication.
Do not neglect the means to mitigate the water when loading the dishwasher. Their application will extend the life of the unit and increase the quality of washing.
