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 Fig. 1. The main functions that the dishwasher performs after pressing the start button and closing the door are:
- Draining water (usually at the start of any selected program).
- Water filling.
- The beginning of the washing process.
- Adding detergent (included at the stage of loading the dishes).
- Heating water.
- Washing process (takes time depending on the selected washing program).
- Draining.
- Filling in rinsing water.
- Rinsing.
- Draining.
- 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 an 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:
- time (duration of execution).
- the degree of water heating (from 50 ° C to 75 ° C).
- 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 phased implementation of the washing program from start to its complete 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.

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 dishwasher repair instructions and this video will help you.
Despite the fact that imported washing machines serve flawlessly for more than 10-15 years, users often turn to service centers to repair Beko washing machines.
In most cases, the problems are of a minor nature, so we suggest considering cases when you can carry out repairs yourself without any problems.
Having entrusted the inspection of the machine to an experienced master, you can be sure that he will quickly and professionally find what the problem is. But because of the high prices for services, many home craftsmen are trying to save money and make repairs to the Beko washing machine with their own hands.
Almost any SMA model lends itself to home repair: ELB 57001 M, RKB 58801 MA, LNU 68801, etc.
This approach is quite justified - often repairs cost exorbitant prices, and sometimes the price is such that you can buy a new machine. At the same time, even the most "killed" car can serve for several more years after repair.
Don't want to throw away your Veko machine and buy a new one? Try to figure out the problem yourself and fix it yourself.
The design of the Beko washing machine also determines the nature of its breakdowns. Consider the typical malfunctions of this brand of washing machines:
- The water does not heat up to the set temperatures, the wash goes in cold water in any program. Or vice versa - the water overheats.
- Water is slowly drawn into the tank or not filled at all.
- The Beko washing machine does not start because the door does not close tightly enough.
- There is water in the tub at the end of the wash (this may be accompanied by a strong hum).
- The drum rotates with grinding, crashing, clanking and other uncharacteristic sounds.
- Not a single wash mode starts - all the lights on the machine blink.Or the program works, the indicator lights up, but the machine does not wash.
- The machine cannot be started with the power button (with the power cord plugged in).
- Models with an electronic scoreboard issue error codes H1, H2, H3, H4, H5, H6 and H7. The machine does not work.
Important! There may be other signs of failure. We have considered the most frequently encountered among users of SM Beko in Russia.
As mentioned earlier, all malfunctions are accompanied by certain symptoms - from minor malfunctions to complete failure. The problem of a home craftsman always lies in one thing - how to connect the existing signs of a breakdown with its causes. Here you just need the knowledge and advice of narrow specialists.
Below we will briefly summarize information about the main breakdowns.
If you know how to use a Beko washing machine, then you know that the water used up after washing is never clear and clean - this is the specificity of washing. To prevent dirt, threads, hair, etc. from clogging the pump, there is a special drain filter on the way to it, which mainly suffers from blockages.
Your task is to find this filter, which is usually located at the bottom of the washer, under a small hatch or behind a panel. How to proceed next:
- Before removing the filter, do not forget to substitute a basin or place a rag under the machine, as the remaining waste water will surely pour out of the hole.
In a number of Beko models, along with the filter, an emergency drain hose is also included - with its help it is much more convenient to drain water into any container.
- To remove the filter, simply turn it to the right.
- Next, clean the filter by hand and rinse under the tap.
- Armed with a screwdriver, you can also clean the pipe at the same time - it is usually also clogged with debris from the waste water.
- Once you have tools at hand, do not rush to put them away - for prevention, clean the filter that is on the water supply (it is located at the point where the hose is attached to the back panel). Sand and rust from the piping slowly collects in this filter and eventually interferes with the normal flow of water into the drum.
- After cleaning the filler filter, do not rush to put it back in place - also check the drain pump. Often, Beko's washing machines, during self-diagnosis, find a pump breakdown and signal this using the H5 fault code. But with some breakdowns, the controller may not see minor violations - such as a loose impeller (can be recognized by hearing a hum).
- To check the pump, start the drain mode and look through the hole in the filter plug to see how the impeller behaves. If it rotates, then everything is in order, and if not, then you need to clean or even replace the pump.
To eliminate such a problem, you will also need at least partial disassembly of the Beko washing machine, but more on that below.
First, let's say that one of the most vulnerable nodes in the SM is a thermoelectric heater, simply a heating element. The mineral salts present in the water crystallize under the influence of hot water and settle on the heater in the form of a familiar scale - like in a kettle. Plaque does not allow heat to pass through, so the heating element does not give it to water and burns out.
If there is no scale, you have soft water, or you use special products, this does not mean that the heater could not burn out. The heating element has its own resource of production, and, perhaps, its time has just come.
If the heating element fails, you will learn about it by errors H2 and H3. To be 100% sure what happened to him, first get to the heater. In some Beko models it is at the back, in others at the front.
So, how to disassemble a Beko washing machine, find a heating element, check and replace it, read on:
- If the heating element is in front, then in order to remove the front panel, you need to remove the hatch cuff. To remove it, proceed carefully - if something goes wrong, then your activity is fraught with damage to the cuff and leaks.
- You will not see the heating element in its entirety - only its shank with two contacts and wires going to them.
- Disconnect all wires.
- Take a tester and measure the resistance. Typically 25-30 ohms are normal. If the indicators are different (for example, infinity), then the breakdown is obvious.
- Remove the heating element by unscrewing the nut from the bolt that holds it under the drum.
- Clean the installation site of debris and deposits.
- Install the new heating element in the reverse order, reconnecting all the wiring.
This video shows, in strict sequence, how to remove, check and replace the heating element:
If the heating element turned out to be Spanish, then you need to check the temperature sensor (thermistor). You will find it under the top cover. How to get and check the sensor:
- Remove the top cover by unscrewing the screws.
- Dismantling of the sensor is carried out with the removal of the cuvette for detergents and the control panel - all this interferes with getting to the element. Once you reach the sensor, free it from the wires.
- The resistance measured by the tester should be 4.7 kOhm in room conditions.
- Heat the sensor in a glass of warm water - after that the readings should drop. If this does not happen, the sensor needs to be changed.
- The installation of a new sensor is carried out in the same way as removal, only proceed in the reverse order.
If you have the knowledge and experience in repairing electrical devices, then you will quickly eliminate breaks in contacts or their oxidation. You only need a diagram of the Beko washing machine - you will find it in the manual or on the manufacturer's website, indicating the model of your CM.
As for electronics, everything is ambiguous here.
Repair or replacement of an electronic controller (control board) requires specialized knowledge and rich experience.
Considering that an electronic module can cost as much as a third of your washing machine, it is not profitable to engage in amateur activities. Especially if the board needed minor repairs, which any master will perform for little money. If you "condemn" the module, then you will have to buy a new one, and an innocent breakdown will result in complex and expensive repairs.
Remember that it doesn't matter what characteristics your machine is designed for - they break in exactly the same way. If you received a 5 kg Beko washing machine, the faults will be the same as in a similar 3 kg model. To prevent the Beko washing machine from breaking, we advise you to use the operating instructions and follow the rules prescribed there.
At one time, a British magazine conducted a survey of readers about the quality of household appliances. There was only one unequivocal conclusion - there is no problem-free household appliances. Moreover, the models of the elite - class, after 5 - 6 years, begin to malfunction. Noteworthy is their conclusion about the degree of reliability of dishwashers of leading brands. This is how the British named Ariston, Bosch and Electrolux the leaders in durability among the brands.
But, as mentioned, even the most reliable home assistant starts to malfunction. And when this happens there are two ways out: roll up your sleeves and undertake repairs yourself, or call for help from a specialist from the service center. Statistics speaks in favor of the first option, namely, most dishwasher malfunctions are eliminated at home. And in the statistics of service centers the leading place is occupied by “no drain”.
Therefore, minor and not very complex malfunctions can be completely eliminated by yourself, but for this you need to get acquainted with the device of the dishwasher and consider possible options for repairing dishwashers. Which is the purpose of this article.
The body, as in any household appliances, serves as a base on the basis of which all the main components and assemblies of the machine are located. The main elements of a dishwasher are:
- Control panel, which is always located on the front side of the machine. It consists of a digital microcontroller (timer), control buttons and an indicator display (which can be used as an indicator beam, which is projected onto the floor surface).
- Spray blocks or impeller. This is a dishwashing water supply system. Consists of a system of pipes and nozzles (there are two of them: upper and lower). Due to the special design, water and detergent are supplied under high pressure, which ensures high quality dishwashing.
- A float switch is a means of protection against water leakage. A hollow plastic cylinder floats up at a certain volume of water and thereby closes the contacts. Depending on the design, these contacts close the pump activation circuit for pumping out water or perform emergency closing of the water supply valve to the machine.
- The drainage unit consists of a drainage pipe, which is connected to a common sewage network and a sump pump. The principle of operation is identical with the drain in washing machines, who knows.
- Water inlet with built-in inlet valve controlled by a digital microcontroller.
- The water pump is used to supply water to the spray guns and, on some models, to drain the water. As a rule, it is located together with an electric motor, which starts the pump.
- Filters are designed to "catch" food debris and other objects.
These are actually all the most important and most common elements of dishwashers in case of malfunctions. Of course, different manufacturers can add other blocks that expand the functionality of the unit. But all of the above is the base, having dealt with it, you can easily deal with the individual structural elements of your car.
