We all own one or another range of household appliances. She helps us with the housework quite well, clearly fulfilling her assigned role. Many believe that the factors of using an automatic dishwasher are not fully justified - not only water is consumed, but also electricity, and the device itself is not in the cheapest category. Isn’t it easier to leave everything as is and wash the dishes the old fashioned way by hand, “enjoying” the monotonous routine process?
Approaching the issue from a radically opposite angle, it is undoubtedly necessary to highlight the obvious advantages of dishwashers, which free us from routine manual washing of dishes. Household appliances came into mass use to save people from tedious, monotonous work. Electrical appliances are constantly being improved and modernized by manufacturers, and dishwashers are no exception.
So, now it’s worth talking about the advantages of household automatic dishwashers, of which, as it would seem at first glance, there are not so few.
- Reaction tap water in combination with detergents, it is reflected in the healthy appearance of the skin of the hands and nails. With a dishwasher, you can safely not worry about excessive dry skin and unsightly appearance of your nails, and you should completely forget about a ruined manicure.
- A dishwasher frees up a lot of additional free time for its owner, which he can devote to more important matters or simply relax with his family. Loading dirty dishes into the machine takes no more than 5-10 minutes, the rest is a matter of technique. The main thing is to set the desired washing mode. At first glance, it will seem to many that washing dishes by machine takes too long, but this is a highly subjective assessment; you just need to remember the time spent independently wiping the washed dishes with a towel before putting them back in their proper place.
- Excess consumption electrical energy fully compensated by water savings. As a rule, the difference in water spent on a machine wash is 3-4 times lower than that of a hand wash. By converting the results into a monetary equivalent, you will be convinced that you are significantly saving your family budget.
- The quality of dishes washed in a dishwasher greatly dominates the quality after hand washing. Such a colossal difference is achieved by using water at a temperature of 65-70 degrees in the machine. In addition, automatic correction of the entire washing process and subsequent disinfection of dishes is possible only at the hardware level. Obviously, the sensitivity of human hands cannot compete in this matter.
- The use of special rinse aids in dishwashers gives a special shine to clean dishes, even the most capricious cutlery and fine crystal wine glasses.
Finally, everyone, sooner or later, wants to feel at the crest of technological progress and lead a personal army of irreplaceable household mechanical assistants. After all, your free time is their considerable merit. However, you should not neglect the simplest rules for caring for household appliances. Otherwise, unscheduled
Today I want to share with you a topic in which I will tell you, what is a dishwasher, And what to look for when choosing a dishwasher. So…
Dishwasher ( English dishwashing machine) - electromechanical installation for automatic dishwashing.
Most people, in conversation, use another word to define this - "dishwasher".
Applications and types of dishwashers
The dishwasher is used both at home and in catering establishments, and depending on these conditions, it is classified into 2 types - "home" And "industrial" dishwashers.
- Industrial dishwashers. The main characteristics are the dimensions, which are larger than those at home. Number of programs. Power, thanks to which it can work under heavy and frequent loads.
- Home dishwashers. There are 3 types of home dishwashers:
— Narrow. Width 45 cm. Designed for 9-13 sets of dishes.
— Full-length. Width - 60 cm. Designed for 7-16 sets of dishes.
— Compact. As a rule, due to their small size, they fit on the table and can accommodate up to 7 sets of dishes. The big disadvantage is that it is not always possible to accommodate even large plates.
How the dishwasher works
Preparation. Cleaned of large food residues, the dishes are placed in baskets and trays intended for dishes different types. The washing program is selected. Special containers are loaded with (powdered or tablet) detergent designed specifically for dishwashers.
Soak. As with hand washing, soaking works well to remove dried or burnt-on food fragments. The dishes are splashed cold water with (or without) a small amount of detergent and left for a while. Subsequently, when washing, the soaked residues are removed much more easily.
Washing. Water at the required temperature (depending on the selected washing program) with detergent under pressure is sprayed in thin streams by rotating sprayers onto the dishes from different sides, depending on the model of the machine, washing away food residues and grease.
Rinsing. At the end of the washing procedure, several rinsing cycles occur with clean water with the addition of rinse aid, thanks to which no traces of dried drops of water remain on the dishes after drying.
Drying. Then, if the machine has a drying function, the dishes are dried. This happens either with the help of a stream of hot air (less common) or by moisture condensation. The last method is implemented as follows. During the last rinse of the dishes, the water (and, as a result, the dishes themselves) heats up. Then the water is removed, and the cooling walls of the machine condense the moisture evaporating from the hot dishes on their internal surfaces. The latter flows down the walls into a common drain.
hot water, but it would be fair to note that it is impossible to wash dishes with bare hands at this temperature. But this is possible with a dishwasher, which washes and rinses dishes at high water temperatures (≈55-65°C). In addition, at this temperature, detergents are also easily washed off from dishes, which cannot be said about manual washing.
Saving. Water consumption is much lower compared to manual washing (9 - 20 liters versus 60 liters for 12 sets of dishes). Savings of 3-6 times, which is achieved through repeated use of the same water at each stage of washing.
Savings are also achieved due to unnecessary costs, with constant purchases of a wide range of detergents and abrasives, sponges, brushes and the like, which, although they cost a little, but if you count the costs for these products purchased per year... For a dishwasher, a special salt to soften the water and one type of detergent are enough.
Versatility. Hot water supply is not required. In fact, the dishwasher can be used at any time, as long as water and light are available. In addition, it also saves your money, because... When washing by hand, both cold and hot water are used, which is more expensive.
Saving your time. The role of a person in washing dishes comes down to loading dirty dishes into the machine and unloading clean ones. The process itself does not require participation or observation and can occur at any time, even when you are not at home.
Disadvantages of a dishwasher
1. Inability to wash certain types of dishes or other kitchen utensils:
— non-heat-resistant plastic items;
— wooden planks;
- tin or copper items;
— aluminum cookware;
- crystal dishes with lead impurities;
— cutlery made of rusting steel;
- cutlery with wooden, horn, or mother-of-pearl handles;
- antique dishes, the coating of which is not heat-resistant;
- glued dishes.
2. The machine takes up additional space; in addition, the installation location must provide access to the door for loading and unloading dishes.
3. The machine requires an electrical connection designed for a power of about 2 kilowatts.
Now let's take a look main characteristics that you need to pay attention to when choosing a dishwasher, designed to significantly simplify our 
everyday life.
Capacity
As we have already said, dishwashers are standard (floor-standing), divided into two types according to the width of the machine - 45 cm and 60 cm, and compact (tabletop), the size of which (HxWxD) is approximately 45x55x50 cm.
A device with a width of 45 cm can accommodate 8-13 sets, and a machine with a width of 60 cm can hold up to 16 sets of dishes. In addition, there are compact models designed for 4 sets, but such models are less efficient and cannot accommodate large dishes.
Built-in or free-standing
Based on the type of installation, dishwashers, like other ones, are divided into built-in and freestanding. Built-in, in turn, are divided into partially built-in and fully built-in. The difference is that in partially built-in machines the control panel remains visible, while the control panel in fully built-in machines is located on the upper edge of the door.
To let you know when the wash is complete, a beam of light is projected onto the floor next to the machine during the wash, the so-called “floor beam”, which disappears when the wash program ends.
Energy efficiency/washing/drying class
There are three important indicators in dishwashers: energy consumption class, washing class and drying class. The energy consumption class is a characteristic of energy efficiency, the washing class is an indicator of the quality of washing, the drying class is a characteristic of the quality of drying dishes.
European standards provide for 7 classes of energy consumption and 7 classes of washing efficiency, designated by the letters of the Latin alphabet from A to G. The higher the class, the lower the energy consumption, the better the quality of washing and the higher the price of the machine.
Washing and rinsing
Dishwashers can have from 3 to 20 washing programs. The most used ones are:
— "very dirty"— provides additional washing;
— "intensive"- for pots and pans;
— "soak"- for very dirty dishes;
— "daily wash"— standard washing at 50-60°C;
— "economy mode"— easy shortened cycle at 45-55°C for washing plates, mugs, thin glass;
— "quick wash (Express)"— for lightly soiled dishes (saves 20% of water and electricity).
There is also a delicate wash for fragile dishes (30°C), washing of crystal and porcelain, bio-programs using detergents, containing enzymes, which allows you to wash dishes at low temperatures.
The machines themselves can select a washing program depending on the number of dishes. This is done in two ways.
— The more dishes, the fewer drops reach the bottom and the less water in relation to that loaded from the water supply will return to the recirculation system.
— A sensor is installed on the pump that determines the amount of water drained from the dishes. Based on these indicators, the number of dishes is determined (after pre-rinsing) and the washing program is selected.
Drying
There are also post-wash drying settings, such as condensation drying and warm air drying. Condensation or energy-saving drying saves energy, but may leave small stains on the dishes from dried drops.
Filters and removal of product residues
There are models with self-cleaning functions, filtration systems, and a waste crusher that allow you to load dishes into the dishwasher without cleaning them first. Filters and food waste crushers remove food particles and ideally eliminate them without clogging drainage system dishwasher.
Noise insulation
Since the dishwasher can be one of the loudest appliances in the home, when choosing a dishwasher, look for models with enhanced sound insulation. Each manufacturer may call the noise insulation function differently, but you need to pay attention to the noise level in the product characteristics - in the quietest models the noise level ranges from 47 to 57 decibels.
Display
New dishwasher models are equipped with a digital display so you can imagine how long a particular washing, rinsing or drying program will take. Additionally, some models include controls on the top of the door to smooth out the outside surface.
Dish baskets and interior surface
Dishwashers are equipped with several baskets, the height of which can be adjusted depending on the size of the loaded dishes. As a rule, the upper basket contains special holders for cups and compartments for small plates, which, thanks to their durable design, can guarantee the safety of breakable dishes. Cutlery is placed in a special container, which guarantees safety when loading and removing sharp and cutting objects. The lower basket is provided for larger dishes. All racks are made of durable and flexible material, and dishwasher interiors are often made of stainless steel.
Dishwasher modes and functions
- System "Water Sensor", "Aqua Sensor", "Sensor system" determine the purity of the water after preliminary rinsing. The machine compares these indicators with the maximum permissible values and determines whether it is necessary to change the water or continue washing with the old one. This allows you to save water and electricity.
— Half load mode It also saves water and energy, reduces the load on the machine, which helps extend its service life.
— Most dishwasher models are equipped with delayed start function, in case you want the washing of pre-loaded dishes to begin during the period of least load on the electrical network, or after you have left home.
— Program phase indicator will allow you to determine at what stage of operation the machine is. The remaining time indicator shows how much time is left until the end of the machine's operation.
Function "Duo Wash" allows you to simultaneously wash both delicate and heavily soiled dishes. The principle of operation is this: in the upper basket the pressure and temperature are lower, in the lower basket (pans, pots) - higher.
— Pulsating pressure change water due to the two-speed motor in the feed pump allows you to wash dishes perfectly, because under low pressure the dirt becomes soft, under strong pressure it is completely washed off.
- System "Rack Matic" allows you to stick out the top box as much as possible and reach all its corners. It is easy to load dishes, the height of the upper box is adjustable.
- Lock "Easy-lock" will close the door itself if you have not closed it tightly and it remains ajar less than 10 degrees.
— "OptoSensor" or "water hardness sensor"- a sensor that automatically regulates water hardness, maintaining its optimal value. Thanks to infrared rays recognizes scale and automatically adds salt to soften the water, and if the salt supply needs to be replenished, the salt replenishment indicator lights up.
- Many dishwashers require Possibility of mid-cycle stops.
— Elite dishwashers allow you to create own dishwashing programs and record them in memory.
- Mode "Heating dishes" turns on after the main wash program has finished, so that the dishes you remove are pleasant to your hands.
— All manufacturers recommend adding rinse aid to the machine. It helps wash away any remaining detergents and adds shine and a pleasant smell to dishes. Therefore, it is good if there is rinse aid level indicator. It lights up when the rinse aid needs to be replenished.
— System automatic detection malfunctions(service diagnostics of faults) signals errors.
— User-friendly presence of an acoustic signal.
- Cars can have removable containers for long cutlery, baskets for cups, forks and spoons, lighting.
Dishwasher Safety
— During installation, the dishwasher must not be connected to the network.
— Dishwashers are manufactured according to the first class of protection with grounding and a three-pole plug. Therefore, the electrical wiring in the apartment must be grounded, and the power supply must correspond to the data given in the instructions for the dishwasher.
- To protect against damage electric shock There is a device that automatically turns off the power to the machine if the door is opened during operation. The locking lock on the door serves as reliable protection against curious children.
— Dishwashers have stable protection against voltage surges, which is typical for our network.
— The “Aqua Stop” safety system prevents water leakage, regardless of the nature of the leak: depressurization, damage to the hose or drain. This system protects the machine from backflow of water. It protects the apartment from flooding.
— Dishwashers have a built-in pump that pumps water out of the chamber if the water reaches a dangerous level and threatens to leak.
— The machine has a sensor that regulates the water level and turns off the heating of the heating element if there is not enough water in the machine. High quality pipes also protect against leaks. The bottom plate is waterproofed, the drain pump has an anti-blocking system.
— Many dishwashers have an integrated control panel. If the machine detects a malfunction that has arisen during operation, a signal is immediately given, the warning lights come on, and the consumer himself can determine the type of malfunction.
— If the dishwasher is not built-in and access to the side door is possible, a special lid should be used to close the side hinge.
— Special baskets and holders protect against mechanical injuries when using sharp objects.
Dishwasher connection
Connect the dishwasher only to qualified specialists!
Usually it is connected to cold water. And then the machine heats the water to the desired temperature.
— Firstly, during emergency and scheduled work with hot water supply, you will be left without a reliable assistant.
— Secondly, cold water is cleaner than hot water.
— Thirdly, the temperature of the water in the tap sometimes exceeds 70 degrees, and a dishwasher that is not designed for this temperature may fail.
You can install a mixer that will allow you to use both hot and cold water. But it has one significant drawback - its high price.
How much does a dishwasher cost?
All dishwashers can be divided into several groups:
Economy class models costing $200 - 400
functional class models costing $450 - 550
comfort class models costing $600 - 750
elite class models costing from $800 and above.
Within each class, the cost of dishwashers varies depending on the functionality, size and, to a lesser extent, the design of the model.
Built-in models are usually more expensive than free-standing (solo) models.
Prices are approximate, because... also depend on the country and place where the dishwasher was purchased.
Dishwasher care. Dishwasher detergents
Special products must be used in dishwashers:
- powder;
- rinse aid;
- salt.
One kilogram of powder is enough for 70-80 washing cycles. Sometimes detergents come in tablets. They are consumed more slowly than powder, but may not dissolve until the end of the wash.
Rinse aid is used to remove detergent residue and add shine to dishes.
Be sure to add regenerating salt to the machine ($4-6). It softens the water, removes the dull tint from the dishes and the appearance of white spots, and restores the working condition of the ion exchanger. It forces water through the resin it contains. Salt restores the properties of the resin. An indicator in the machine shows the presence of salt and the need to replenish it. The local sanitary and epidemiological station (SES) can provide information about the hardness of the water in your water supply.
Sometimes, in order to save money, table salt is used instead of special salt. But it must be clean and large. In order to check whether table salt is suitable for the dishwasher, you need to dissolve 1 teaspoon of salt in a glass of water. If the water remains clear, the salt is dishwasher safe.
Every housewife knows that those appliances that we look after and keep clean last a long time. Therefore, to extend its service life, you need to take care of the machine. After washing, it is recommended to wipe the dishwasher with a dry cloth, and if necessary, clean the filter. It is recommended to repeat cleaning every 3-6 months. It is better to wipe the internal parts with a soft cloth soaked in warm water. Rinse the spray nozzles carefully under running water. For washing exterior and internal parts Only special detergents should be used.
— degreaser — removes grease from the internal parts of the dishwasher;
- anti-scale - guarantees optimal operation of your machine and is used after a degreaser;
- deodorant - eliminates unwanted odors in the dishwasher.
Washing dishes is an unpleasant task; fortunately, special machines have taken over the functions of cleaning dishes from dirt for quite some time now. All that remains is to do right choice dishwasher - and you can forget about washing dishes by hand forever.
Advantages of dishwashers
- Significant reduction in water consumption (up to 8000 liters per year).
- Possibility to use only cold water, which is especially important in the absence of hot water supply.
- Contact of the skin of the hands with washing reagents is completely eliminated, which allows the use of stronger compounds than with manual washing.
- All types of dishwashers provide significantly more efficient rinsing than is possible when washing dishes by hand, due to the use hot water.
- Finally, the biggest plus is the reduction in time spent washing dishes; in fact, you only have to load dirty dishes into it, select a program, and then take out clean ones - the machine will do the rest itself.
There are many factors to consider when choosing a dishwasher. Not only the sizes, but also the functions and modes of dishwashers.
The main parameter by which dishwashers are compared is the number of “dish sets” that the machine washes in one cycle. The concept of “set” includes three plates, the same number of spoons, a knife, a fork and a cup and saucer. Of course, this concept is conditional, and is used precisely so that the performance of different dishwashers can be compared.
According to dimensions, the division is carried out into:
- desktop;
- narrow;
- full-size
The first type is the most compact. The width and length of such a machine do not exceed 55 cm, height - 45 cm. It can be placed on the table, or it can be hidden under the sink if there is not enough space to install a large dishwasher. This option is suitable for a small family, since it cleans no more than five sets of dishes in one cycle.
The second type has a standard height and depth (85 and 60 cm), but a reduced width - 45 cm. Finding a place for such a machine is easier; it is suitable for a family of three to five people.
The third type is the largest, 85x60x60 - these are the dimensions of a full-size dishwasher that processes up to 15 sets of dishes at a time. It makes sense to buy such a machine if you have a really big family and you really like to cook.
When choosing a dishwasher, you also need to immediately understand whether it will stand alone or can be built into kitchen set. Based on how these units are installed, they are divided into two types, one of which, in turn, is divided into two more:
- free standing,
- built-in (fully or partially).
Full embedding will ensure “invisibility” of the car in the interior, and partial embedding will allow easy access to the control panel.
How efficiently a dishwasher works is judged by its class.
Work quality class.
Seven classes mean seven levels of work quality and are designated in Latin letters from A to G. A corresponds to the highest quality, and as a result, the maximum price.
— wooden planks;
- tin or copper items;
— aluminum cookware;
- crystal dishes with lead impurities;
— cutlery made of rusting steel;
- cutlery with wooden, horn, or mother-of-pearl handles;
- antique dishes, the coating of which is not heat-resistant;
- glued dishes.
everyday life.— "very dirty"— provides additional washing;
— "intensive"- for pots and pans;
— "soak"- for very dirty dishes;
— "daily wash"— standard washing at 50-60°C;
— "economy mode"— easy shortened cycle at 45-55°C for washing plates, mugs, thin glass;
— "quick wash (Express)"— for lightly soiled dishes (saves 20% of water and electricity).
— A sensor is installed on the pump that determines the amount of water drained from the dishes. Based on these indicators, the number of dishes is determined (after pre-rinsing) and the washing program is selected.
Function "Duo Wash" allows you to simultaneously wash both delicate and heavily soiled dishes. The principle of operation is this: in the upper basket the pressure and temperature are lower, in the lower basket (pans, pots) - higher.
— Secondly, cold water is cleaner than hot water.
— Thirdly, the temperature of the water in the tap sometimes exceeds 70 degrees, and a dishwasher that is not designed for this temperature may fail.
functional class models costing $450 - 550
comfort class models costing $600 - 750
elite class models costing from $800 and above.
- rinse aid;
- salt.
- anti-scale - guarantees optimal operation of your machine and is used after a degreaser;
- deodorant - eliminates unwanted odors in the dishwasher.
A-class machines use less water to wash dishes than representatives of lower classes. Accordingly, they need less detergent and special salts for rehydration. Thus, each work cycle requires less cost for Consumables, and the operation of the machine is generally cheaper. For comparison, here are the numbers: in class A, 15 liters of water are consumed per working cycle, in class E - up to 25.
Energy class. A dishwasher's ability to save energy is also assessed by classes, which are as many as efficiency classes, and they are designated the same way.
Drying class.
- Types of dishwashers are also distinguished by drying class, which can be carried out in different ways:
- condensation;
ventilation.
And in this case, class is determined by Latin letters from the beginning of the alphabet, and decreases towards its end. The most productive drying method is ventilation using heated air. After the process is completed, you take out the dishes not only dry, but also warm.
Noise level. A very important characteristic of any household appliance is the noise it produces during operation. The body of any household appliance usually indicates the average noise level in decibels, which is what you need to focus on. A quiet dishwasher is one that makes noise between 47 and 57 dB.
Dishwasher functions
- Among the many different functions of dishwashers, it is not so easy to determine what is really needed and what is a marketing ploy to improve sales. Let's try to figure this out to understand what you should pay special attention to when choosing a model.
- Injectors.
- Water is supplied through these devices, and the greater their number and the smaller their diameter, the more efficient the washing. Filters. Typically, filters are used to purify water before washing.
- best solution
- - three degrees of purification. Using pre-purified water will extend the life of your machine."Stop". Among the dishwasher modes, there are necessary ones, there are additional ones, and also those that you can do without. Among the additional ones, pay attention to such a function as “stop” - the ability to pause the operation of the machine at any time, it will be very useful if the machine suddenly breaks down or a leak occurs.
- Programming. Dishwashers have not only standard modes, but also a manual programming function - you can set the conditions for washing dishes that suit you best in each specific case. Supplements
Appearance
The quality of dishes often depends on how they are rinsed after washing. For example, acidifying additives will make the crystal shine. Some machines have the ability to add rinse aids; the indicator will show their level. Rinse aids help remove detergent completely, give dishes a pleasant smell and maintain their attractive appearance for a long time. The choice of dishwasher is also influenced by the convenience of the control system, the presence of a timer, a signal about the end of work, a notification system about the end of the next cycle, as well as a display that helps control functions. The minimum number of operating modes, or programs, is four. Maximum may vary depending on
different manufacturers
- , and reach eighteen. As a rule, no more than four of the most convenient modes are constantly used.
- All types of dishwashers have modes such as:
- Daily. Standard dishwashing mode, water temperature - about 55 degrees, average consumption of detergents and water.
- Fast. Suitable for minimal soiling of dishes. This mode uses 20% less electricity, detergents and water than the standard mode. Economical. Typically, coffee and tea cups and other small and not very dirty dishes are washed in this mode. Water temperature 40-45 degrees, minimal consumption of detergents and water.
Heavy pollution.
- Soak. It is used to wash away dried dirt on dishes, as well as in cases where something is burnt to the bottom of the dishes.
- Delicate.
- Special function for washing fine porcelain, crystal, and gold-plated dishes.
Allows you to save money if you don’t have a full load of dirty dishes, but what you do have needs to be washed urgently. Whether these functions are needed in your case is up to you to decide. Some manufacturers also offer “sensor” functions to extend the life of the machine. It may also be useful additional function
“double wash”, or Duo Wash - by placing fragile and delicate dishes in the upper part of the basket, and very dirty ones in the lower part, you can wash them in one pass, without the risk of damage or failure to wash.
Additional dishwasher modes can reduce the cost of the washing process, help save electricity and water, and control the process, for example, the Easy-lock function will control the closing of the door and protect against leaks by tightly closing the door, even if you forgot to press it tightly before turning it on. There is even a function for monitoring the layer of scale on the metal parts of the machine, and automatically adding a softener.
Separately, it is necessary to say about machines equipped with a self-cleaning system. You can load dishes with food residues into them - they will be washed away, crushed and filtered, so there is no risk of clogging your communications. This is really convenient, but will require additional costs. IN developed countries dishwasher is classified as household appliances essentials, along with the refrigerator and stove. A dishwasher is considered a more necessary thing than a vacuum cleaner and washing machine
. Cleaning and washing can be postponed for a short period of time, or entrusted to a housekeeper. You need to wash the dishes yourself and as often as you eat. Scientists have found that A family of four spends more than 200 hours washing dishes by hand each year.
A dishwasher helps improve the psychological situation in the family by reducing problems in the distribution of dishwashing work. It will allow you to postpone washing until a time convenient for you and will be able to do its job without your participation, for example, at night, when the lowest electricity tariffs apply. Variable electricity tariffs have long been established in the West. In Russia, the number of people wishing to install cold and hot water flow meters is increasing. A dishwasher for a family of 4 will save about 7,800 liters of water per year compared to washing by hand. In order to wash 12-14 sets in a machine, you need 14-18 liters of water, and when washing by hand, about 60 liters. It takes no more than 15 minutes to load and remove 12 place settings. For example, the popular Electrolux dishwasher for 12 place settings uses 18 liters of water with an intensive program for heavily soiled dishes.
Modern dishwashers make it possible to wash not only all types of cutlery and dishes, but also baking trays, crystal vases, removable parts of refrigerators and stoves, and large pots. For washing fragile objects (crystal glasses) and heavy grilles, special baskets, holders and trays, nozzles and removable shelves are provided.
But we must not forget that the dishwasher cannot wash items that are saturated with water (sponges and napkins) or cannot withstand high temperatures (plastics warp when heated). Products made of bone, wood, brass, mother-of-pearl, silver and tin should not be washed in the dishwasher. Detergents can damage their surfaces. The wood will become rough, and silver will tarnish when it comes into contact with metal parts in the car.
Main characteristics of dishwashers
Electromechanical control of the machine is carried out using buttons or on/off keys on the panel and regulators for washing programs and other functions.
The consumption of electricity and water determines the efficiency of the machine. The less water is spent on washing, the less electricity and detergents are consumed. Most of the machines on the market consume 17-20 liters per wash cycle with a temperature of 60-65 °C, highly economical brands consume 14-16 liters, low-economical brands consume up to 26 liters. The value of this indicator depends on the size of your wallet and water payment systems.
After choosing the type of dishwasher, you need to familiarize yourself with the main characteristics: maximum load of dishes, energy and water consumption, efficiency and economy classes of drying and washing, noise level.
The maximum load of dishes indicates the maximum performance of the dishwasher with the lowest consumption of detergents and water and the lowest energy consumption. An incomplete load will lead to an increase in consumption for the set of dishes. If there is an urgent need to wash a small amount of dishes, it is necessary to have a half-load function. If there is no such mode, then when the machine is 2/3 loaded with dishes, it consumes the same amount of detergent, water and electricity as at maximum load.
