Dishwasher is a worthwhile, attractive business that removes unnecessary worries about caring for dishes. However, there is no such technique that functions flawlessly throughout its operational life. Often, a dishwasher tank creates problems. The owner should know what to do in such a situation. Do you agree?
We will talk about what kind of breakdowns can be fixed on your own without any problems. We will show you in which cases it is better to entrust the repair to the representative of the service workshop. Based on our advice, in any situation you can quickly restore the machine’s efficiency with your own hands or fix everything with the help of a master.
Briefly about the design of the dishwasher
Despite the kind of magic that a housewife awards in a kitchen dishwasher, this technique, from a technical point of view, is quite simple.
In fact, it is a waterproof box-shaped bathtub, inside which hot water is sprayed.
The external image of the machine does not tell the user that in front of him is a unique technically perfect unit. An ordinary cupboard where dirty dishes are placed, and removed completely clean at the end of the work cycle
As a rule, an aqueous soap solution is used, which contributes to a better dishwashing. This solution, passed through the nozzles, watered cleaning objects. Dirty water is collected in the bottom of the tank, absorbed by the pump and removed. Then the drying process starts.
One of the many options for the implementation of the automated control panel dishwasher. Just a few function keys in the neighborhood of the LCD. This kit is enough for complete control.
The system is controlled by automation, the level of complexity of which depends on the manufacturer and model design. An article on this interesting issue will familiarize you in detail with the general principle of operation of dishwashers of various brands.
Automatic controls include various functions as needed:
- spraying water;
- loading detergent from the dispenser;
- water extraction from the tank;
- pumping water;
- filling with water and its removal;
- inclusion of a heating element.
Hot water is poured into the dishwasher through a supply hose, which is connected through a shut-off tap to supply water to a centralized water supply.
Additionally, the water supply is controlled by the inlet valve of the dishwasher installed inside - under its body. The inlet valve is electronically controlled and connected to the basic components of the structure.
One of the often breaking parts looks like this - the inlet valve, which regulates the water supply. Often due to wear of their own components (gaskets, rods), this part becomes defective
The valve opens and closes, for example, as needed to supply water to the rotating nozzles. The spray system contains nozzles, typically located at the top and bottom of the tank.
Due to the nozzles and the water pump inside the tank of the dishwasher, high water pressure is created, so that the dishes are washed clean.
Tank in plastic design - such components, as a rule, have cars from the range of budget models. Meanwhile, during operation, savings on the working chamber result in extremely unpleasant consequences
The dishwasher tank actually acts as the main structural element, since all other elements are schematically lined up around it. Therefore, it is logical to consider first of all the malfunctions associated with the tank, and the possible causes of their occurrence.
Tank breakdowns and their elimination
It is technically correct to call this part not a tank, but a working chamber or bath. Given the need to seal the working chamber, it becomes clear that one of the primary malfunctions that may occur during operation is depressurization.
Problem # 1 - the appearance of water on the floor
The working chamber of the machine has a loading hatch. When the washer is loaded with utensils, the hatch should be closed tightly by the door. Sealing is provided by a special sealing gasket.
But over time, it may lose its properties. If the gasket is worn, the leakproofness of the hatch-to-door module is impaired. The consequences of such a defect are obvious. Water in the washing process seeps through the disturbed areas, drains onto the kitchen floor.
The gasket is the reason why the dishwasher often becomes defective. In particular, the breakdown consists in the depressurization of the tableware loading channel. The loading module seal usually has to be changed
Detecting such a malfunction is easy. If water appears on the floor under the dishwasher, carefully inspect the perimeter of the loading hatch to determine where the dishwasher needs repair and where the tightness is not broken.
And it is better to take a piece of toilet paper, wrinkle it in the palm of your hand and smoothly walk along the perimeter of the loading door with the resulting “crumb”. In places of leaks, the paper will certainly get wet - it will show the depressurization points.
In the photo, an attempt to adjust the door strips on which the sealing plait sits. Sometimes, thanks to such an operation, it is possible to get rid of water leakage due to depressurization of the doorway
To eliminate the defect associated with depressurization of the loading hatch is possible only by replacing the sealing material. Attempts to apply some kind of pads will not lead to anything.
Moreover, such repair options will only aggravate the situation. True, sometimes the tightness is restored after careful adjustment of the door pressure to the hatch window.
The process of completely changing the sealing harness. In principle, the operation takes a little time and is free to do with one's own hands. The main thing is to have a replacement kit, as well as a standard tool
Defects associated with the depressurization of the tank of a dishwashing machine can occur in other places. For example, at the point of accession of water supply or in the nodes of the supply to the spray arms.
As a rule, the feed unit with filters is located under the bottom of the tank and is connected to the working chamber through a passage, also equipped with a sealant. If it is damaged, a leak is inevitable.
Problem # 2 - lack of water collection / drainage
To start the washing process, a certain water level must be present inside the tank of the machine, which is determined by the level sensor. If the tank is not filled up to this level, the automation will not start the dishwasher.
The dishwasher filter, which is installed on the water supply line from a centralized water supply system, looks like this. However, depending on the model of the machine, the performance of the filters may vary.
A traditional reason for the lack of water is a clogged filter. To solve this problem is not difficult. It is only necessary to open the filter and clean or replace its elements. If everything is normal with a set of working water level in the tank, but the automation still does not give the go-ahead to start, most likely the cause is a malfunction in the water pump.
The fluid collected to the required tank level must be pumped to the nozzles. If this does not happen, then you should pay attention to the pump and to the nozzle openings. Perhaps spray devices are simply clogged with dirt.
The spray device, the design of which contains several nozzles. It rotates at the moment of operation of the machine, thereby achieving a uniform distribution of water in the tank area. But nozzles are often clogged with dirt
Another defect, which can also be attributed to the working chamber and which is associated with the circulation of water, is the lack of discharge of the spent liquid or, on the contrary, its overflow. The pallet design is also equipped with a level sensor (float).
If it is working, then when a certain level is reached, the drain (drain) pump is turned on and removes the waste water. In the case of poor-quality discharge or complete absence, for example, due to a faulty pump, an overflow effect is formed. The sensor is triggered and turns on the automation of the warning function.
Circuitry of the pallet of the machine where the float sensor is located. In this part of the washing machine there are several points - potential objects for the appearance of defects. This can be either the sensor itself or seals on the eyeliners
So, damage to the float sensor is not ruled out, and such cases are not unique in practice. The result is the same: a non-working machine or water leakage to the floor.

Problem # 3 - physical defects of the working chamber
This type of failure is a rare occurrence. Nevertheless, such incidents happen. Typically, physical damage to the dishwasher tank occurs during the long-term operation phase. That is, time does its job - the materials wear out.
The lion's share of cases with physical deterioration of the tank account for structures made of now popular plastic. It is a plastic working chamber, having worked for an average of 3-5 years, is capable of cracking from frequent changes in temperature and exposure to chemicals added during washing.

With such a defect, the dishwasher technically acts as usual. The washing process is not disturbed.
But on the floor near the unit, water always accumulates. The more cracks on the tank body, the larger the puddle and the more often the network feed is turned on. The only way to get rid of such a malfunction is to completely replace the working chamber.
Doing it yourself is difficult to do with your own hands, since you have to disassemble the car almost completely. Therefore, the replacement of the washing bath is most often carried out through the after-sales service.
A complete disassembly of the dishwasher unit will be required in case of replacement of a faulty tank. This operation is quite difficult to perform on your own in an apartment.
You can completely eliminate the problem with a physical defect in the working chamber in a simple way - when buying, choose a model that uses a working washing bath made of stainless steel.
Problem # 4 - poor-quality dishwashing
How to explain poor-quality dishwashing machine? The working chamber in such cases, as if, with nothing. At first glance, this is so, if you do not take into account that the electric heater (TEN) is nevertheless built into the tank body and not another part of the dishwasher.
An electric heater is a component that you often have to deal with. In particular, replace due to failure. In practice, it is noted: the quality of the heating element directly depends on the brand of the manufacturer
So, if the temperature of the water during washing the dishes does not reach 60 ° C, then there is every reason to see dirty plates / cups / glasses at the end of the washing cycle.
The inability to set the optimum temperature is evidence of a failed heater. Such a malfunction can only be determined by using a special power tool - a tester.
In addition, trying to determine the integrity of the electric heater for people who are not friends with electricity is strongly discouraged. This is the work of the service center masters. The electric heater should be called by the tester to make sure that it is completely malfunctioning. Then the heater must be replaced with a new one.
Most of the cars produced today are equipped with breakdown warning systems. You will learn how to understand the codes, for example, the Ariston Hotpoinnt dishwasher by reading the very useful information we have proposed.
How to replace the heating elements of a Bosch brand dishwasher is described in detail in the next article, the contents of which we recommend to familiarize yourself with. The selection tips and technological details presented in it will help to cope with the problem with your own hands.
Dishwasher diffuser in the upper horizon of the tank. Common causes of breakdown (malfunction) of this element - clogging of nozzle holes with small debris
Poor washing of sets and other table accessories loaded into the machine is also possible due to partial clogging of nozzle openings. With such a defect, the dishes also come out of the tank with food debris, since in the process of washing the jets of water simply do not capture the entire dishes.
The solution here is to disassemble the sprinklers and clean the clogged holes. This work can be done independently.
