The prevalence of dishwashers is less than that of washing machines, but every day more and more people acquire this necessary assistant for the kitchen. In general, this kitchen equipment is very reliable, but breakdowns are not excluded. A popular problem is the dishwasher is not picking up water. Let's try to understand the reasons for this and find out how to fix the breakdown.
Typical reasons
Regardless of the model of the dishwasher, the principle of operation is the same for everyone, although they differ in overall dimensions, power, capacity and other characteristics. The reasons why water does not enter the machine can be as follows. I must say that they are the same for most units.
Among the most popular reasons why the dishwasher does not draw water, it is possible to highlight the wrong connection of the inlet filter. Also, the cleaning element may fail. Often clogged internal water filters. Such a malfunction may occur due to a faulty door. Sometimes the machine does not want to draw water due to problems with the pressure switch - a water level sensor. Often diagnosed and malfunctions in control systems.
AquaStop
Models of cars can be different, but the causes of breakdowns are the same for everyone. But in some more modern models there is an AquaStop system. What it is? This is a kind of protection against unauthorized leaks. The hose through which liquid is supplied from the water supply to the dishwasher is covered with a special protective cover. In the event of an emergency, the system itself will shut off the fluid supply to the unit. This protective system can be triggered by various faults. As a result, the dishwasher does not pick up water. This option also does not need to be excluded when diagnosing a household unit.
Door malfunction
The door of any machine is always equipped with a special locking mechanism. It serves to protect against possible leaks. If the blocking unit fails, the machine will not be able to start the wash cycle and a malfunction will occur when the unit is unable to collect water.
To correct the situation, it is necessary to repair or replace the locking device. In service centers, this operation will cost a thousand rubles. If there is an opportunity to purchase the necessary original spare part and there are certain skills for repairing household appliances, then you can perform the replacement yourself.
Intake valve failure
Each dishwasher is equipped with a special valve for supplying water. When the unit starts to work, an electrical signal is applied to the valve. It should open and then water will begin to flow into the machine. Due to voltage surges or natural wear and tear, the valves may “burn out”, as a result of which the dishwasher does not collect water.
To restore the normal operation of this unit useful in everyday life, you need to purchase and replace this valve. After that, the machine should work properly and please the owner.
Water level sensor
What kind of sensor is this? Experts call it a pressure switch. This is an electronic sensor that measures the level of water pressure and transmits information to the control module. Then, after analyzing the information received, the module decides how much water is needed for each cycle of a particular dishwasher program.
If this sensor fails or does not work correctly, then the signals to the control module may either not be supplied at all, or they may arrive incorrectly. This is another reason the dishwasher does not pick up water. Replacing the sensor will help to replace the sensor with a new one. This operation in the service center will cost about one and a half thousand rubles.
Control Module Failure
If the dishwasher is not collecting water, the reason may be in the module. Without exception, all units are equipped with an electronic module. It is a software package that issues commands to other executive units. So, the inlet valve collects water on command, and the drain valve drains. If the machine does something wrong, then the reason may be in the module. If the dishwasher is not collecting water, what should I do? You can try to reset the module. How to do this is indicated in the instructions for the typewriter. If the module is completely out of order, then only a replacement or a flashing will fix the situation. Neither one nor the other will not succeed on its own - you need special equipment. In service centers, this operation will cost around 2.5 thousand rubles.
How to clean the filter?
If we take into account the quality of the water that flows in our taps, the situation when the dishwasher does not draw water is quite predictable. Among the first causes were problems with the filter. Due to the hardness of the water, the filter is often clogged. The detail is a small thin mesh - it can clog it.
Such a breakdown can be easily repaired by hand. But this requires some experience. Having previously blocked the water, unscrew the supply hose. Further, in the place where the hose should be connected to the machine, you need to find a protective net. It must be cleaned with a needle, or immersed in a solution of citric acid for half an hour or an hour. In service centers for servicing household appliances, craftsmen will take 600 rubles for this work.
Picks up and merges
Users of this household appliance also turn to service centers with another, no less popular problem - the dishwasher draws and drains water without starting the program. This malfunction may be accompanied by a humming pump. At the same time, the tonic does not respond to keystrokes, and rebooting does not help. Let's try to figure out the reasons.
Tank leak
If the dishwasher draws water and immediately drains, then most often the problem is with the leakage of the tank of the machine. When collecting fluid, the bulk of the units controls so that it does not leak. The pallet of the machine is equipped with leakage sensors. As soon as water gets to the sensor even in a minimal amount, the machine will stop working or will not start. Units equipped with displays can display error numbers.
You can fix such damage yourself. If the cuff is worn out or the clamps on the pipes are loosened, then this can easily be changed with your own hands. If the hoses and fittings are out of order, this is also eliminated by one's own hands.
Expert Advice
If you are replacing pipes and hoses, it is important to clean the seats of the fittings well from oxides and dirt. If dirt remains, water will seep from precisely these places. If there are doubts about the tightness, it is better to immediately use heat-resistant sealants.
Tank crack
Another reason why the machine picks up and immediately drains water is damage to the tank. Cracks are a fairly common occurrence, especially in inexpensive cars.
By reducing the price for the consumer, the manufacturer tries to save on everything, including the thickness of the metal for the tank. The wall thickness of some tanks is very small. Damage to the tank is possible even with a slight blow.
Leak Sensor Problems
If the dishwasher is not picking up water, buzzing, then this indicates that the water is draining. The pump is buzzing. The problem may be due to a faulty leakage sensor. It simply sends incorrect data to the control unit.
If the sensor is exactly working, then it is worth checking the wiring. Often the cause is poor connections in the connections. It is better to clean and crimp them again.
Inlet valve
One of the reasons may be the failure of the filler or intake valve. The last one, which works correctly, should open when voltage is applied to it. If the voltage disappears, the valve should close accordingly.
However, it also happens that in the event of malfunctions or blockages, the valve opens, but then, when the voltage disappears, it does not close. In this situation, water overflows, and the machine is forced to pump out water.
Cleaning the valve is not possible - it does not disassemble. To eliminate the breakdown, it is necessary to replace the failed part.
Recommendations
Most often, these valves fail because a large amount of poor-quality, dirty water passes through them. Deposits appear on the inside. As a result, it does not work correctly. It is recommended to install the filter on the water supply.
This will help extend the life of the valve and other machine components. The cost of these cleaning systems can be different. But, as a rule, a high-quality system for cleaning a water supply system will cost at least ten thousand rubles.
Dishwashers "Bosch"
This German brand produces very high-quality equipment, although troubles happen with the products of this company. Despite the high quality, it happens that the Bosch dishwasher does not pick up water.
Among the reasons, the masters of service centers distinguish standard for dishwashers. So, the tap supplying water to the machine may be closed. There is no pressure in the water supply. The cause may be various sensor failures - for example, if the Aquastop sensor breaks, then the water supply will be blocked.
Remedies described above are also relevant for dishwashers of this brand. The device they have is similar to other units with the exception of some small things.
Electrolux
With these machines, despite the production (and they are made in Sweden), interruptions also occur. Often, owners complain that the Electrolux dishwasher is not picking up water. Diagnosing this problem is very simple - the washing process will not start without water, and the machine will not work.
If such a problem occurs, then you need to check the health of the machine itself. Next, you need to make sure that the valve that regulates the water supply is in good condition. Then check whether the door of the machine is tightly closed. Both gaskets and locks must be in good condition. The control unit receives a signal that the door is not closed and water is not flowing.
It is also recommended to check the condition of the hose through which water enters the tank. If it was possible to find out malfunctions of a hose, it should be replaced. Then the machine will work.
Conclusion
We examined most of the reasons why the washing machine does not draw water or drains it. Many of the breakdowns can be fixed on their own, but for the solution of some it is better to contact qualified specialists.
