Dishwasher: operating principle, device, spare parts, operating instructions

The equipment of a modern kitchen necessarily includes a dishwasher. It can not be said that without this technology, the processes of economic activity will stop, but thanks to it, a lot of time is saved, not to mention the elementary getting rid of routine troubles. The market is saturated with offers of this kind, but really high-quality models should be looked for in the lines of major manufacturers of household appliances. The range of premium manufacturers includes a dishwasher, the principle of which is based on the processes of wetting and rinsing. But all the differences between the models are reduced to the technological realization of this principle.

General information about dishwashers

People who are planning to use this machine for the first time may think that this is a real miracle of technology, which relieves of unpleasant washing of dishes. However, this is not quite true. The unit is quite simple and understandable from the point of view of operation. Practically any dishwasher, the principle of operation of which is based on the action of special rinsers, ensures a rather high washing efficiency. Another thing is that the user is required to perform some actions. This is not only setting up and managing work programs and modes, but also maintaining the equipment in good working order.

Also do not forget that such equipment is powered by electricity. For example, the functional dishwasher "Electrolux" in the performance of the ESF 9420 has an A-class of energy consumption, which is economical enough. And for those who aspire to maximum economy, it is also desirable to adjust the operation of the machine to the optimum time in terms of the most advantageous mode of energy accounting for the meter.

Design and construction

Externally, the unit resembles the same washing machine. Even in size, these representatives of the segment of household appliances converge. But, of course, they have completely different functions. The basis of the machine is the power plant, which provides the function of the upper and lower atomizer. Virtually every dishwasher has these components. The device and the principle of operation are interrelated, that is, the engine activates the nodes and mechanisms that distribute the rinse aid and other detergents through the float valve . As a result, the cleanliness of the dishes is ensured. A separate infrastructure represents the devices responsible for the supply of water, without which the workflow can not be executed. This task is realized by an intake valve, supplemented by a filter and a pump. For hot and cold water, different hoses are intended, but if necessary, the machine can perform heating on its own.

Principle of operation

Before the start of the workflow, the user must perform several actions, including loading dirty dishes into a special unit and filling detergent into the appropriate container. The first stage of the unit will be the filling of a special container with water and its subsequent distribution to form a solution with detergent. Ready-made cleaning mixtures are fed to the dishes against a background of copious irrigation with clean water. Continuous flow of the jet is carried out by the dishwasher. The principle of operation, however, depends on different software modes and can assume a particular frequency and speed of the actions. At the next stage, the rinsing procedure begins. The dishes are disposed of not only from the remnants of dirt, but also from detergent. The final stage is drying. Different machines differ in the principles of doing this operation, but its result is always the same - giving the user clean and dry dishes.

Types of machines

Basically, such equipment is distinguished by the type of installation and the form factor. So, on the market you can find built-in and detached models. The first option is integrated into the working kitchen cabinet and practically does not take up excess space. This type of machine is good in compact dimensions, but installation problems may occur. In addition, the infrastructure with water supply is more likely to be hidden, which is not the best option in terms of operational safety. However, modern programs of the dishwasher can detect the disturbances in the water supply processes by sending appropriate signals through the indicators. As for stand-alone machines, they have large dimensions, although not always. This unit practically does not require the execution of dirty work during the installation and allows one to serve large volumes of dishes in one approach.

User's manual

In order for the machine to last as long as possible, care must be taken to meet the performance requirements. First of all, it is important to load only those volumes that correspond to the capabilities of a specific model. The way to install dishes is also important. For example, it is advisable to place the dish dirty side to the sprinklers, which are most often located in the central part above the engine. Separate rules are devoted to the choice of materials, since not every dish can be served in such a machine. Modern instructions for operating the dishwasher recommend not using silver and steel products in one session, as a result of which corrosion damage can be obtained. Particular attention should be paid to porcelain, glass, crystal and plastic. Utensils from these materials are generally sensitive to high temperatures, and to certain chemical components in detergents. Products with woody parts and at all to subject such contacts to water it is impossible.

Rinse aid for dishwasher

If you perform washing cycles only with the addition of detergent, then after a certain time, the stains of the original chemical burns will become noticeable on the dishes. This phenomenon is due to the fact that after the procedure, the chemicals are not completely washed away. Eliminate this problem will help the rinse aid for the dishwasher, which is added to a special compartment in parallel with the base detergent composition. The main task of this additive is that its components help to efficiently wash dishes surfaces not from dirt, but from used washing solution. In choosing a conditioner, it is important to consider its conformity and the type of the machine itself, and, of course, the dishes. Also, manufacturers produce different compounds for soft and hard water.

Repair and spare parts

On the internal state of the machine can be recognized by various signs, including the quality of the performance of the detergent function. Frequent faults include irregularities in the operation of the intake valve, damage to the filters, clogging of the drain valve and the unit with the sprayer. These problems can be solved independently by replacing the element - the main thing is to stock up spare parts for a specific model. For example, spare parts for dishwashers Bosch can be purchased at the dealer center. Usually users of machines of this brand order filters and heating elements. By the way, the consumables and spare parts of this German manufacturer in some models coincide with the analogues from Siemens.

Manufacturers

Almost every manufacturer of kitchen appliances is engaged in the manufacture of dishwashing equipment. For example, the dishwasher "Electrolux" refers to the budget segment, although some of its modifications cost 15-17 thousand rubles. Can not be called representatives of the lower class. The basis of the same family of this company are inexpensive models designed to perform basic operations. Usually these are machines with a low level of manufacturability and the quality of the element base.

Nevertheless, the same German companies can rightly be referred to premium products. Another thing is that spare parts for dishwashers Bosch or Siemens in the form of valves, seals and filters, too, may be required if the technique is used in harsh conditions. That is, the premium brand does not guarantee an absolute level of reliability.

How to choose the best model?

Counting before buying should be such parameters as the amount of downloads, modes of operation, support for certain programs, controls, etc. If there are no specific requirements for functionality, then you can confine yourself to an inexpensive model from the line of the same brand "Electrolux" worth 7- 8 thousand However, the really high quality of dishwashers starts at the level of 13-15 thousand. In the same segment you can find attractive technology options. For example, in the last series, manufacturers already provide for wireless control of machines.

Conclusion

Cleaning and washing equipment in recent years has made a huge breakthrough, offering the user new levels of performance. But still there are common problems with such equipment. This is a high level of energy consumption, and noise with vibrations, as well as considerable size. All these problems include a dishwasher, the principle of which involves the use of chemicals for the effectiveness of operations. Manufacturers seek to minimize these shortcomings, but so far they have not been eliminated. More promising areas of the company consider the increase in structural reliability, increase in the speed of work, and the development of new principles of cleaning and drying.
