poured many glasses of water into the bunker and. it worked.

noticed earlier when on, there was a noise of pumped water, now pumping was idle, I remembered when they bought it and moved it around the room (turned over a couple of times) there was water inside.

I can't explain, but the open door and the heat in our absence> + 45C apparently all evaporated inside. in general, experts comment if this is possible.

Krona dishwashers were among the first to appear on the household appliance market. The attitude towards dishwashers of this model among consumers is different: someone speaks positively about their work, and someone does not like them. Still, the Krona dishwasher does not disappear from the shelves, finding its customers.

Dishwasher Krona

Krona manufactures dishwashers in two versions, differing in size, weight and load volume:

• dishwasher Krona BDE 4507 EU;
• assembly model BDE 6007 EU.

Both options have similar performance characteristics.

The Krona BDE 4507 dishwasher will be a good purchase for a small kitchen. The dimensions of the BDE 4507 EU unit are 44.5x55x82.5 cm, the weight is 33 kg, which significantly saves the usable area of ​​a small kitchen. The dimensions of the BDE 4507 EU dishwasher allow you to simultaneously load 8 full dish sets into it, which is quite enough for a small family.

Due to its relatively large size, it is worth installing the Krona BDE 6007 EU dishwasher in kitchens where there is enough free space. The dimensions of the BDE 6007 EU unit are: 59.5x53.5x82.5 cm, weight 39 kg. At the same time, it is possible to wash a set of dishes for 12 persons.

Dishwashers of the Krona model are easy to install by yourself, following the attached instructions, they are highly efficient, easy to operate, but not very economical. Electricity consumption is 1760 W for the entire dishwashing cycle.

In order for the Krona dishwasher to work for a long time and efficiently, the instructions for using the appliance recommend:

• Position the kitchen utensils so that they do not move under the running water.
• Place sharp objects (knives, forks) away from the rubber seals of the machine.
• Plastic, in order to avoid melting, do not place near heating elements.
• Monitor the power cord for good condition. If damage is suspected, do not use the device, but contact the service center for repair.

It happens that the machine stops working correctly, the self-diagnosis system displays an error code. Depending on the code, the Krona dishwashers may need to be repaired at a service center, and some problems can be rectified by yourself. The instructions for the dishwasher tell in detail what errors in the operation of the Krona unit occur most often, and indicate how to solve the problem.

The most common Krona dishwasher error codes are:

• E1 indicates that the dishwasher is not getting water well. This can occur due to insufficient water pressure, problems with the filter or water filling valve. If the E1 error is caused by a malfunction of the kapan or filter, it is not necessary to contact the service center - such minor repairs can be done on your own by clearing the clogged places or installing a new spare part, as indicated in the instructions.
• E2 - slow drainage of water after washing dishes, the causes of the problem and the methods of elimination are similar to those of E1.

• E3 - insufficient water heating to start the program. An error in the operation of E3 can be caused by power surges or a malfunction in the heating elements. Do-it-yourself repairs with the E3 code are undesirable; it is better to contact the service center to diagnose the problem.
• E4 is caused by the Krona being overflowing with water. The solution to the problem will be to check the water level sensors and the outlet valve with the subsequent installation of a spare part instead of the damaged one.
• E5-E7 are associated with a disruption in the supply of electricity to heating systems. Repair of such damage is possible only in specialized workshops, where they will carry out a full diagnosis and install new parts to replace the damaged ones.

Despite the fact that many modern, economical dishwashers have appeared on the home appliance market, Krona kitchen units are still in demand due to their robustness and ease of use.

Thanks to the electronic control board, the dishwashers have a self-diagnosis system. When a malfunction occurs, the module transmits a malfunction code to the PMM display. If you notice that the Krona dishwasher displays an E1 error on the display, then water does not enter the bunker.

Error code E 1 in Krona models indicates that the waiting time for water intake has expired - it has not been drawn into the tank. For what reasons this happens:

• Blockage in the inlet hose, filter, valve.
• Intake valve defective.

• Actuation of protection against leaks "Aquastop" (in such cases, the code E15 may appear).
• Open circuit.

First, rule out a possible network outage, try to reset the error:

• Unplug the machine.
• Wait 15-20 minutes.
• Try starting again. Are the icons on the screen? You need to look for a problem.

You have loaded the dishes, started the washing cycle. Water began to flow through the pipes, but did not get inside, or a very small amount accumulated. What to do, how to fix the problem?

Small debris and rust penetrate from the sewer into the system, which clog the parts. Start by checking the hose:

• Shut off the water supply.
• Unscrew the hose from the PMM body.
• Take a look inside. If there is a blockage, flush it under pressure from the tap.
• Then inspect the mesh filter. Wash it too, and in case of stubborn dirt, soak it in a citric acid solution.

If no blockage is found, proceed to check the functionality of the element.

Additionally, you need to check its wiring. The control board sends a signal to the valve about water intake, its membrane opens and allows the flow. But if the wiring is broken, then the signal will not reach its destination. How to fix the situation? The train needs to be replaced.

To test the valve, apply an operating voltage of 220 volts to its coil. Does the membrane open? This means that the element is working.

The electronic part can be checked with a multimeter. Apply the test leads to the pins of the part. The working element should show from 2 to 4 kΩ. If broken, install a new part.

The inlet hoses are often equipped with a mechanical Aquastop. Inside there is an absorbent sponge, which, if it leaks, absorbs water and shuts off the supply. In this case, only the replacement of the part will help.

Now you know why the Krona dishwasher can show the E1 icons on the screen. Use our instructions, do it yourself.

We made a renovation about two years ago, then we immediately installed a new kitchen with a built-in dishwasher. Previously, I somehow always managed without her, it was not difficult for me to wash the plates and spoons with handles. But my husband decided that we needed a dishwasher. OK. Decided, chose, installed.

We chose the Krona BDE 4507EU dishwasher. It is built-in, 45 cm - which was very suitable for us, it can accommodate a set of dishes for 8 persons. Intuitive control panel.

There are a total of 7 dish washing programs in it, from Intensive for very dirty dishes (pots, plates with dried food, etc., washing time 2 hours 35 minutes) to Fast for slightly dirty dishes (glasses, crystal, washing time 30 minutes) ...

Looking ahead, I use the Economy program, which runs for about 1.5 hours. This is enough for me to wash both cups and pans.

A lot of dishes fit into the machine, sometimes we have to “save” it for a couple of days, because our family of three does not have time to stain so many dishes to load the machine completely. In total, the machine spends about 13 liters of cold water on one wash.

Now a few words about the characteristics of the car. Its dimensions (WxDxH) - 450x540x925 cm. Mains voltage 220-230 V, Power consumption - 1760 W. Machine weight 33 kg.

To wash the dishes, you first need to pour salt into the lower container, which is located under the lower rack (pictured on the left). If there is not enough salt in the car or there is not enough salt, then a light on the dashboard will light up - Salt. It is also possible to adjust the salt intake to optimize its intake.

Add detergents and rinse aid - on the dishwasher door.

I chose a special powder for washing dishes in the dishwasher, I didn't like the tablets, they leave some stains. But more on that in the following reviews. So, fill in the powder, rinse aid, set the desired program, and close the machine. After a few seconds, it starts working. If you look through the crack between the table top and the car door, you can see a flashing blue light - while it is flashing, it means that the washing program is running. At the end of the wash, the machine will beep 8 times, which means that you can open it, turn it off and take out almost dry dishes.

The washing process in the machine itself is carried out by special moving nozzles sprinkling in all directions. They are located under the upper and lower grilles (in the photo above, where the salt compartment is visible, you can also see the nozzles).

The baskets themselves are removable; to clean the filter (below, to the right of the salt compartment), it is easy to remove the lower basket.

And now a little history. The story is like this. As I said, we made repairs a long time ago, and for about a year the apartment was not living. Well, that is, repairs were being completed in places, furniture was bought, chic and shine were induced. When we stopped by, they didn't use the dishwasher for the first time either. And just recently I decided to try it at last. Of course, hands are more familiar, but why do you need equipment in the house if you don't use it? The dishwasher still served as a cabinet for me 🙂 Having taken the instructions, I carefully studied everything, and decided to do a test run. The car rumbled, you can hear that water was pouring, then everything was quiet. For a long time. And after a while there was a strong smell of plastic. Heated plastic! And I was alone at home with a child, and I became scared. The car was silent, and the smell intensified. I turned off the car, ventilated the apartment, and waited for my husband.My husband came, but could not help with anything - he understands dishwashers as well as I do 🙂 They called the master. He arrived, and from half a kick began to pull out my built-in typewriter from under the table top. Then I watched with curiosity his bold actions.

He twisted and twisted something, knocked, checked, opened, started and turned off the car. So why didn't the machine work? It turned out that everything is simple. When we installed the equipment, but a test run of the dishwasher was carried out, it worked. But after a certain amount of time, the dishwasher was not used, and something happened to the motor: either it stalled, or it got stuck, or something else. The master poked around with it and the machine started working.

At the same time, the master, after listening to my complaints about the car, said for the future: at least once a month drive the car, even if it is empty, otherwise the engine will again refuse to work. And of course, periodically clean the entire car. And when you have to leave for some time, you should not only turn off the water supply tap, but also open the door in order to preserve the seals and prevent the appearance of unpleasant odors. Who knows, that fellow 😉

After my dishwasher was cured, we began to actively use it. Well, very convenient! While she washes, I can go about my business, deal with the child, etc. We turn it on mainly in the evening, but not at night - the car makes a noise. Of course, when the doors are closed, the noise is not so audible, but still. In addition, after the end of the wash, the car needs to be opened, and somehow you don't want to get up specially for this at night. The car makes a noise constantly during washing, becoming silent only when it heats up the water. 8x squeak is heard everywhere - don't miss it! Washes perfectly. Again, depending on what to use. The pills leave streaks.

I would definitely recommend the dishwasher to anyone who doesn't like to wash the dishes by hand! It saves both time and water, saves both hands and nerves 🙂

Understand the structure of the dishwasher, familiarize yourself with the main units of dishwashers in Fig. 1, their purpose and principle of operation.

LET'S CONSIDER DETAILED DESIGN AND OPERATING PRINCIPLE OF THE DISHWASHER:

Rice. 1 Dishwasher device

The device of dishwashers, regardless of the manufacturer and its model, can be represented by a single diagram in Figure 1. The main functions that the dishwasher performs after pressing the start button and closing the door are:

1. Draining water (usually at the start of any selected program).
2. Water filling.
3. The beginning of the washing process.
4. Adding detergent (included at the stage of loading the dishes).
5. Heating water.
6. Washing process (takes time depending on the selected washing program).
7. Draining.
8. Filling in rinsing water.
9. Rinsing.
10. Draining.
11. Drying.

Eleven main functions are responsible for high-quality dishwashing. Eleven main functions are performed by functional units (parts, devices, peripherals) of dishwashers. The sequence of turning on / off the peripheral devices of the dishwasher is controlled by the electronic control module (hereinafter referred to as the processor) similar to that shown in Fig. 0.

Washing program - the sequence of instructions executed by the processor. Washing programs differ:

1. time (duration of execution).
2. the degree of water heating (from 50 ° C to 75 ° C).
3. the presence or absence of the pre-soak function.

Let's consider the main units of dishwashers and their functional purpose using the example of the step-by-step execution of the washing program from start to its full completion.

You have selected a washing program, added detergent, added rinse aid (optional), pressed the start (start) button and slammed the dishwasher door. What happens next?

1. THE PROCESSOR CHECKS THE DOOR CLOSING AND GIVES THE COMMAND "TO WASH AFTER THE PREVIOUS WASH OPERATION":

The lock in Figure 2 is responsible for closing the door (in Figure 1, see number 15). If the door is properly closed, the lock closes the contacts.This is a “door closed” signal to the processor. Having received the "door closed" signal, the processor sends a command to the drain pump Fig. 3, (in Fig. 1, see number 8) "drain the water". The drain pump begins to perform its function.

At the same time, the processor with a frequency of 5-6 seconds, within 2-3 minutes, gives the command "water fill". The water inlet valve Fig. 4 (in Figure 1, see number 17) opens, water enters the dishwasher. The drain pump runs continuously, pumping out water. After a certain period of time, the drain pump stops working. The rinsing operation from the previous dishwash has been completed.

2. THE PROCESSOR GIVES THE WATER SUPPLY COMMAND:

The water inlet valve opens. The dishwasher is drawing up water. The level (amount) of water collection is controlled by the water level sensor Fig. 5 (in Fig. 1, see number 7). The sensor is set to be triggered at a certain amount of water (sufficient for high-quality dishwashing). When a sufficient amount of water has been collected, the sensor sends a signal to the processor. The processor, having received a signal from the water level sensor, closes the water intake valve.

3.4. THE PROCESSOR GIVES THE COMMAND "START WASHING":

Do-it-yourself dishwasher repair, do-it-yourself dishwasher repair. The circulation pump rice 6 starts to work (see figure 1 under number 12). The circulating pump creates enough pressure in the dishwasher to circulate water. Water enters the impellers (sprinklers) Fig. 7 (in Fig. 1, see number 3), then into the holes of the impellers. From the holes of the impellers, water with a certain pressure force washes the dishes loaded into the baskets of rice 8 (see figure 1 under number 1). The impellers begin to rotate, which facilitates the dishwashing process. The dispenser (dispenser) Fig. 9 (in Fig. 1, see number 16) with detergent is opened. Detergent gets into the dishwasher.

5. THE PROCESSOR GIVES THE "WATER HEATING" COMMAND:

The mains voltage is supplied to the heating element Fig. 10 (in Fig. 1, see number 20). The water is heated up to the value corresponding to the selected washing program. The value of the water heating temperature is controlled by the water heating temperature sensor Fig. 11 (see figure 1 under number 4). When the water temperature reaches the required value, the sensor informs the processor about it. The processor disconnects the heating element from the mains, thereby stopping heating. The dishes will continue to be washed for some time. The washing time is controlled by the processor according to the selected dishwashing program.

THE PROCESSOR GIVES THE "DRAIN WATER" COMMAND:

The dishes are washed. The drain pump Fig. 3 starts to work (see figure 1 under number 8), pumping out the water. The water has been pumped out. The processor informs about the lack of water by the water level sensor Fig. 5 (in Fig. 1, see number 7). The next operation is the rinsing operation.

THE PROCESSOR GIVES THE "FILL WATER" COMMAND FOR RINSING:

The mains voltage is supplied to the water inlet valve. The valve opens to allow water to flow into the dishwasher. The water level sensor monitors the supply of sufficient water. When the amount of water in the dishwasher reaches the required value, the water level sensor informs the processor "water is filled".

The processor disconnects the water inlet valve from the mains, thereby stopping the flow of water into the dishwasher. The processor turns on the circulation pump. Water under a certain pressure enters the rocker arms (sprinklers), the process of rinsing the dishes begins. The processor gives a command to turn on water heating. The water heating level is controlled by a temperature sensor. When the water temperature reaches the required value (the processor informs the temperature sensor about this), the heating process stops. The rinsing process itself continues for some time. The rinsing time is written in the program that the processor reads from the external or internal memory.

10. THE PROCESSOR GIVES THE "DRAIN WATER" COMMAND AFTER RINSING:

At the end of the rinsing phase, the drain pump is activated. The water draining phase begins.

THE PROCESSOR GIVES THE "DRYING" COMMAND:

The drying process starts. To dry the dishes, cold tap water is automatically poured into the heat exchanger. All moisture quickly condenses on the cold left side of the wash cabinet and flows into the drain. After the drying process (15-20 minutes), the drain pump is turned on in order to drain off the remaining water after drying. Then the signal of the end of the washing process is heard.

That's all. This is the basic scheme by which almost all dishwashers work. After examining the structure of the dishwasher, you can repair the dishwasher yourself. Additions and deviations from the functions of the main modes are nothing more than an additional service from the manufacturer.

AQUASTOP SYSTEM:

Most dishwasher models are leak-proof. Most budget dishwashers have a tray with a float switch that stops operation when a leak is detected. The middle and top class models are equipped with an emergency valve that blocks the water supply to the machine. See the pictures below (aquastop hose and float fig 12). The aquastop hose is attached directly to the water supply pipe, the float is in the dishwasher pan.

In other words, the AquaStop system consists of a sump with a float and a microswitch, a heavy-duty flexible hose and a solenoid valve module, which is attached directly to the water supply. Figure 12. Water from a hose leak or depressurization of the machine enters the sump. When a certain amount of water is collected in the sump, the float floats up and closes the contacts of the microswitch. The supply of electricity to the safety valve is immediately cut off, the valve closes and shuts off the water supply. At the same time, water is pumped out of the base of the machine.

If the dishwasher refuses to work, analyze the information above, analyze the list of possible malfunctions below and perhaps you will receive an answer to the question "what happened?" and troubleshoot the dishwasher yourself.

Below is a list of common dishwasher malfunctions and how to fix them. This information was accumulated over the years of practice, and acquired structural forms. The information will be useful to both novice craftsmen and those who are used to repairing everything with their own hands. Below is a list of fourteen points characterizing the malfunction of the dishwasher. Knowing the contents of the items will make it easier to learn the secrets of the repair. Each item contains a detailed description of the logical troubleshooting paths of the item name. Knowledge will help fulfill DIY dishwasher repair... Repair the dishwasher yourself

Do-it-yourself dishwasher repair is the ultimate dream of every man. You really want to be indispensable in the eyes of a woman.

There are many helpers on the home appliance market today - dishwashers are among them. Anyone can afford such a car now. Finding a car according to your financial capabilities is not a problem now. Units that serve as dishwashers in your kitchens are made by many manufacturers and have different prices. Manufacturers Siemens, Electrolux, Bosh have developed such models that you will never have problems with. But any equipment breaks down sooner or later, and even if it is an assembly of well-known manufacturers, you will not be 100% insured against it.

Self-repair of dishwashers is possible when three qualities are combined: the desire to save money, learn how to independently make minor repairs of technical equipment and basic knowledge of technical disciplines in order to read the diagrams on your own.

Self-repair of dishwashers is the dream of every housewife

“How to repair a dishwasher” is a frequent question of housewives.Everyone can do a dishwasher repair on their own, you just need to learn a little. For this, a special forum has been created + dishwasher repair can be a simple task if there are people who can give good advice and good advice.

Here you can get acquainted with detailed instructions for repairing do-it-yourself dishwashing machines, useful tips for diagnosing machines of various brands. Here you can learn how to connect and install the machine, disassemble the main components in case of emergency. In fact, self-repairing a dishwasher, that is, with your own hands, is a simple and interesting task.

How to repair a dishwasher? Learn to read diagrams!

Your dishwasher is not working. What to do?

Experts will tell you that when the dishwasher, for some reason, is out of order, then you need to call the masters who will not only carry out diagnostics, but also repair the dishwashers + a forum where there are a lot of arguments that minor repairs are possible do it yourself. First of all, the instructions for repairing the dishwasher and this video will help you.

A dishwasher (PMM, dishwasher) is a good help in the household, eliminating the exhausting and unpleasant labor of washing dishes by hand.

Therefore, a breakdown or malfunction of this kitchen equipment forces the owners to immediately contact a service center or call a master for repair.

You can contact a specialized service center for the repair of washing machines RemonTechnik. The center operates in Moscow and the Moscow region. The master will arrive on the day of the application.

Although most dishwasher breakdowns can be repaired by DIYers do it yourself.

Even the most reliable dishwashers of such world leaders as BOSCH (among the common people Bosch), Electrolux, Hansa, Ariston, Siemens are subject to wear and tear. Malfunctions can be caused by:

• Poor quality electricity (voltage surges);
• "Hard water" (a large percentage of mineral salts and small particles);
• Bad or unsuitable chemicals for dishwashers;
• Improper operation of the dishwasher and poor quality care for it;
• Incorrect dishwasher installation.

The video below details the correct connection and installation of the dishwasher.

Practice shows that most of the cases when the dishwasher does not turn on, or cannot continue to work, does not come from a breakdown of mechanisms or electronics, but from clogging filters and nozzles, contamination of various surfaces, scale build-up in valves, or failure to comply with various external conditions - network voltage, water pressure, pressure in the sewer drain.

Therefore, it is important to carefully read the instructions and study the display of the dishwasher, which in some cases can itself diagnose the cause of the stoppage of work. For example, if the lock symbol is displayed, it means that the door is not closed tightly, and the “smart” dishwasher will not draw water so as not to flood the kitchen.

Dishwasher control panel

Various sensors allow the dishwasher to react to changes in internal and external parameters: temperature (thermostat), water level (pressure switch), fluid purity, pressure, engine controllers, and so on. It should be understood that failure of the sensor will affect the operation or may cause a complete stop of the wash cycle. It is obvious that the sensors operate in a dirty, aggressive environment, and may also be susceptible to contamination, which will affect their performance.

The result of the correct interaction of all components of the dishwasher - sparkling clean dishes

In order to repair dishwashers of such brands as BOSCH (in common people Bosch), Electrolux, Hansa, Ariston, Siemens with your own hands, you need to understand the interaction of sensors and the principle of automated dishwashing, and you also need to consider the internal structure of the dishwasher.There is an expression: "water wears away the stone" (destroys, washes away), and this happens especially quickly if the liquid is hot, supplied under pressure, and enriched with detergent.

In industrial machine tools, a jet of water, escaping under high pressure, cuts metal, rocks, and other hard materials. Therefore, the high pressure of water is the main reason why in high-quality dishwashers (for example, Bosch, Electrolux) there is no trace of dirt on the dishes.
