The level of prevalence of dishwashers is less than washing machines, but every day more and more people buy this necessary helper for the kitchen. In general, these kitchen appliances are very reliable, but breakdowns are not ruled out. A common problem is that the dishwasher does not draw water. Let's try to understand the reasons for this and find out how to fix the breakdown.
Typical reasons
Regardless of the dishwasher model, the principle of operation is the same for all, although they differ in overall dimensions, power, capacity and other characteristics. The reasons why water does not enter the inside of the machine may 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, one can single out the incorrect connection of the inlet filter. Also, the cleaning element may fail. Often the internal water filters become clogged. 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 - the water level sensor. Often diagnose and malfunctions in control systems.
AquaStop
Models of cars may be different, but the causes of breakdowns for all are the same. 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 from the water supply is supplied to the dishwasher is covered with a special protective casing. In the event of an emergency, the system itself will shut off the fluid supply to the unit. This protective system can be activated in case of various faults. As a result, the dishwasher does not draw water. This option also does not need to be excluded when diagnosing a household unit.
Door failure
The door of any car 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 draw water.
To remedy the situation, it is necessary to repair or replace the blocking device. In service centers, this operation will cost a thousand rubles. If it is possible to purchase the necessary original spare part and have certain skills in repairing household appliances, then you can replace it yourself.
Failureinlet valve
Each dishwasher is equipped with a special water supply valve. When the unit starts to work, an electrical signal is applied to the valve. It should open and then water will begin to flow inside the machine. Due to voltage fluctuations or normal wear and tear, the valves can "burn out", as a result of which the dishwasher does not draw water.
To restore the normal operation of this useful unit 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 is this sensor? 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. Further, 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 applied at all, or they may not work correctly. This is another reason why the dishwasher does not draw water. Replacing the sensor with a new one will help to correct the situation. This operation in the service center will cost about one and a half thousand rubles.
Failure of the control module
If the dishwasher is not drawing water, the reason may be in the module. Without exception, all units are equipped with an electronic module. He isa software package that issues commands to other executive units. So, the inlet valve draws water on command, and the drain valve drains it. If the machine does something wrong, then the reason may be in the module. If the dishwasher does not draw water, what should I do? You can try resetting the module. How to do this is indicated in the instructions for the machine. If the module is completely out of order, then the situation will be corrected only by replacement or flashing. Neither one nor the other can be done independently - you need special equipment. In service centers, this operation will cost within 2.5 thousand rubles.
How to clean the filter?
Considering 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 often becomes clogged. The detail is a small thin mesh - it can be clogged.
Such a breakdown is easily fixed by hand. But this requires some experience. Having previously shut off the water, you need to unscrew the supply hose. Further, in the place where the hose should be connected to the machine, you need to find a protective mesh. 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.
Dials and drains
Users of this household appliances also turn to service centers with another, no less popular problem - the dishwasher is picking up anddrains the water without starting the program. This malfunction may be accompanied by a pump hum. At the same time, the tonic does not respond to pressing the keys, and the reboot does not help. Let's try to understand the reasons.
Tank leak
If the dishwasher fills with water and immediately drains, then most often the problem is due to a leak in the tank of the machine. When collecting liquid, the bulk of the aggregates controls that it does not flow out. The pallet of the machine is equipped with leakage sensors. As soon as water gets on the sensor, even in a minimal amount, the machine will stop working or will not start. Units equipped with displays may display error numbers.
You can fix such breakdowns yourself. If the cuff is worn out or the clamps on the nozzles are loosened, then this can be easily changed by hand. If the hoses and pipes are out of order, this is also fixed by hand.
Expert Tips
If pipes and hoses are being replaced, it is important to thoroughly clean the fitting seats from oxides and dirt. If dirt remains, water will seep from these places. If there is any doubt about the tightness, it is better to immediately use heat-resistant sealants.
Crack in the tank
Another reason why the machine fills and immediately drains water is damage to the tank. Cracks are quite common, especially in inexpensive cars.
Reducing the price for the consumer, the manufacturer is trying to save on everything, including the thickness of the metal for the tank. Wall thicknesssome tanks are very small. You can damage the tank even with a slight blow.
Leak sensor problems
If the dishwasher does not take on water, it buzzes, then this indicates that the water is draining. The pump is humming. The problem may be related to a faulty leak sensor. It simply sends incorrect data to the control unit.
If the sensor is definitely working, then it is worth checking the wiring. Often the cause is poor contacts in the connections. It is better to carefully clean them and compress them again.
Inlet valve
One of the reasons may be the failure of the filling or inlet valve. The last one, which works correctly, should open when voltage is applied to it. If the voltage is lost, the valve should close accordingly.
However, it also happens that in case of malfunctions or blockages, the valve opens, but then, when the voltage disappears, it does not close. In this situation, the water overflows and the machine is forced to pump out the water.
The valve cannot be cleaned - it cannot be disassembled. To eliminate the breakdown, it is necessary to replace the failed part.
Recommendations
Most often, these valves fail because a large amount of low-quality, dirty water passes through them. Deposits appear on the internal parts. As a result, it does not work properly. It is recommended to install a water filter.
This will help prolong the life of the valve and other parts of the machine. Priceof these cleaning systems may be different. But, as a rule, a quality plumbing system will cost at least ten thousand rubles.
Bosch dishwashers
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 draw water.
Among the reasons, the masters of service centers distinguish standard ones for dishwashers. So, the tap that supplies water to the machine can be closed. There is no pressure in the water supply. The reason may be various breakdowns of the sensors - for example, if the sensor of the Aquastop system breaks, the water supply will be blocked.
The solutions described above are also relevant for dishwashers of this brand. Their device is similar to other units, with the exception of some little things.
Electrolux
With these machines, despite the production (and they are made in Sweden), there are also interruptions. Often, owners complain that the Electrolux dishwasher does not draw water. Diagnosing this problem is very simple - without water, the washing process will not start, and the machine will not work.
If such a problem occurs, then you need to check the he alth of the machine itself. Next, you need to make sure that the valve that regulates the water supply is working. Then check if the machine door is tightly closed. Both seals and locks must be in perfect working order. The control unit receives a signal that the door is not closed and the water is notarrives.
It is also recommended to check the condition of the hose through which water enters the tank. If a hose malfunction is found, it should be replaced. Then the machine will work.
Conclusion
We've covered most of the reasons why your washing machine won't fill or drain water. Many of the breakdowns can be fixed on your own, but for some it is better to contact qualified specialists.
