The machine can be connected to both hot and cold water. Most manufacturers recommend connecting the machine to cold water, as it is cleaner than hot water. But it should be noted that the dishwasher will consume more energy, as part of it will go to heat the water. More economical is the model, which is connected to hot water. The downside is that sometimes hot water can be turned off( for example, due to prevention), which will bring some difficulties. In this case, you can install a special mixer that will allow you to connect the machine to cold and hot water, but this device is not affordable for everyone.
Key Features
1. Cost-effective. This parameter is determined by the consumption of electricity and water. Loading the machine is always recommended for a full - so much more economical. After all, if you load half, the machine will still consume the same amount of resources, as for a full "washing".Exceptions are models in which half load is provided, in this case, the washing affects only the upper basket. Distinguish:
highly economical - will spend 14-15 liters of water at a time, classes -, B, C;
average economical - 16-20 liters per wash, classes - D, E;
uneconomical - about 25 liters per cycle, classes - F, G.
The most common classes are, B, C. There are machines with the Aqua-Sensor system, which, with preliminary rinsing, checks the degree of water pollution, and in case of low contamination uses itagain.
2. Washing efficiency. This parameter depends on many factors.
Water hardness. Everyone knows that in soft water everything is washed much better. And it needs less detergent. To soften water during washing, an ion exchanger is used. It is present in most models. In general, it is better to use purified water.
Number of water directions. The number of directions of the jets is an important parameter of this system. Each manufacturer tries to ensure that one jet does not "crash" into another. Otherwise, there are zones where water does not reach.
Number and shape of spray guns. The quality of the washing depends on the number of nozzles and holes, the more of them the better. With a smaller hole diameter, there will be more, a point spray on the dishes, which in turn will lead to better washing of the contamination.
Method of loading. If you load the dishes correctly, the water will reach all the areas, and you will get clean dishes as a result.
Rinsing. This function eliminates the residue of detergent, gives the dish a pleasant smell and shine. Every time you wash, add a special rinse aid. On average, it needs 3 milliliters per wash.
Drying class. The quality of the sink depends largely on this stage, as it is final. If the dishes are badly dried, the result is unlikely to satisfy you.
Modes and functions
Modern dishwashers have a huge number of functions. Here are the most common of them:
"very dirty" - this function provides additional washing;
"soaking" - for very dirty dishes, on which there is dried mud;
"daily washing" - ordinary washing at 60 degrees;
"economy mode" - simplified mode for washing dishes, cups, occurs at 45-50 degrees;
"quick washing" - used for little contaminated dishes, while saving 20% of water energy;
"delicate washing" - for fragile dishes, washing at 30 degrees;
Timer. Function that allows you to automatically turn on the machine at a convenient time for you.
Time indicator. This indicator shows how much time is left before the end of the mode.
Easy-lock. If you accidentally forgot to close the door, and she moved away less than 10 degrees, then he will do this work for you. OptoSensor - this function adjusts the water hardness, optimizing it. Infrared rays recognize scale and automatically add salt to soften the water.
Washing the dishes
Let's figure out how this process is going on. As mentioned before, it consists of three main stages: washing, rinsing and drying. Cold water is supplied to the dishwasher, which is heated to a certain temperature by means of a heating element. They in turn are of two types:
Open - they are located from below the washing chamber and, accordingly, come into contact with water. Therefore, in the chambers of this type, there is a sharp temperature drop and dishes that can not withstand it, should be placed at the top of the camera. The advantage is that this type allows you to quickly dry the dishes.
Hidden - these heating elements are installed under the washing chamber. In this case, the water does not get on the hot surface. These machines are more economical, since there is no need to spend energy on convection. Of the minuses, you can note the long drying of dishes.
Then, in the already heated water, it adds detergent. And already this mixture, rotating, is served on the dishes. At the bottom of the washing chamber are filters, which are a fine mesh. Large waste is retained there at once, and small ones during subsequent filtration. Then they are rubbed with water and thus, the filters are self-cleaning. Their use helps to save water and therefore electricity. But in some models the filter must be cleaned by hand.
After this, the rinsing process begins. Its essence is that to bring the dishes to the ideal purity. Here, pure water is supplied and a rinse aid is used.
Drying
The final process is drying. It can occur in one of three ways:
Condensation method - the process of condensation of moisture occurs, which falls on the cold walls of the machine. On the outside, air is not supplied. This method helps to reduce energy consumption, because residual heat is used to dry the dishes.
Heat exchange - Steam is directed upwards through the chamber, which is quickly removed when draining. In this case, no drops are formed on the dishes, since there is no condensation. As a result, the dishes remain without divorce. This method is much better than the previous one.
Forced drying - it occurs with the help of hot air, which forms a fan. The best method of drying, but at the same time the most expensive.
Dishwasher control There are only 2 types:
Mechanical - the control is performed using the buttons on the control panel. A reliable and cheap way.
Automatic - more beautiful and convenient. It is necessary to determine the mode of washing, rinsing and drying. And the rest will be made by the car. The display indicates at which stage the machine is located and the washing temperature.
In more expensive models, automatically detect the loaded dishes, and the degree of contamination and the material of which it is made. The display shows the water hardness, temperature, time until the end of the cycle and fault information.
So, let's sum up. Among the advantages can be identified:
washing process occurs at fairly high temperatures, which are better dissolving detergents;
less water consumption than with manual washing;
does not require hot water, the machine can heat the cold;
significant savings on brushes, washcloths and other accessories for washing."Dishwasher" requires only detergent and salt to soften the water;
washing process takes place without human intervention, which saves you time. And some models can automatically start the process at a certain time.
To cons of mono:
can not be washed dishes that are made of wood, aluminum, crystal, as well as dishes that have a coating is not heat-resistant;
takes up an extra space in the kitchen;
requires an electrical connection with a capacity of about two kilowatts.
