During the washing process, the washing machine drains water at least twice. The first time — during the washing itself and again — when rinsing the washed clothes. There are modes in which the washing machine collects and drains water more than twice. If the washing machine constantly pumps water and drains, then something has happened to it and it must be turned off immediately and the cause of the malfunction must be found out.
This problem can occur if your washing machine is not connected correctly or if there is a breakdown. This article will help you find out the reason why the washing machine constantly draws water into the tank and immediately drains it.
Possible causes of malfunction
If your washing machine continuously draws water, this is a bad sign and this problem needs to be addressed immediately if you plan to use your appliance in the future. There are many reasons why a machine stops working properly. It is necessary to understand all possible reasons, and cutting off irrelevant ones, to identify the real reason that the washing machine does not stop pumping water.
Here are the main reasons for the inoperability of the machine:
- Mistakes were made when connecting the washing machine to the water supply and drainage system.
- During operation, the tank of the washing machine lost its tightness and began to leak water.
- The sensor, which determines the water level in the tank, is out of order.
- The inlet valve that regulates the water supply has stopped working normally
- the control unit has ceased to function normally.
If you just bought a car, then the presence of a problem may indicate a factory defect. Maybe in a new washing machine, there is a defective part, or problems with the electronics.

The washer is not connected correctly
If you have just bought a washing machine and are sure that it is in perfect working order, but for some reason it constantly draws water, it means that the drain hose is most likely connected incorrectly.
If the connection of the washing machine is carried out by a non-professional who is not familiar with the elementary laws of physics, then the so-called “siphon effect” may appear. This leads to the fact that the used water from the sewer will begin to flow into the switched off washing machine. And when the washing machine is running, it will pump clean water all the time, which will also constantly pour into the sewer.
You will immediately feel that your water consumption will increase dramatically, the washing machine will either wash poorly or not wash clothes at all.
To fix this problem, it is necessary to properly organize the drain system by raising the drain hose 50–60 cm from the floor level or installing an anti-siphon valve on the hose. It is preferable not to install a siphon valve, which requires periodic cleaning, but to properly organize the drain system.
Leaky washing machine tank
If the tank is leaking in your washing machine, then it will be immediately noticeable in the puddles on the floor. The electronic unit will give a constant signal for pumping, but the tightness of the tank will not allow the machine to work normally and its pump will constantly supply new water to the leaky tank.
Modern machines have special “aqua-stop” systems that block the supply and discharge of water in the event of a leak in the tank. Usually in this case, it is necessary to replace the tank. Welding or brazing of modern tanks is often impossible due to the material from which they are made.

The pressure switch is out of order
Another reason why the washing machine continuously fills with water is the failure of the water level sensor. The water level sensor is a device by which the electronic unit evaluates how much water is in the tank. If the command from the sensor is incorrect, then the electronics considers that there is not enough water in the machine and gives the command to fill the tank. This problem is solved by replacing the pressure switch or repairing it. This device has the following problems:
- The rubber of the membrane loses its tightness. During operation, all rubber parts gradually lose their properties and require replacement.
- The sensor contacts are oxidized. They need to be cleaned up. If the contacts are severely rusted, they must be replaced.
- The appearance of cracks on the sensor tube. In this case, it is necessary to completely change the block. It is very difficult to correct such a problem qualitatively.
It is worth considering that the pressure switch is not a very expensive device, even for new modern cars. Therefore, if there are problems with it, the easiest way is to buy a new one and put it in the washing machine.
Inlet valve failure
If the inlet valve in the washer has stopped functioning correctly, this may also be the reason that the machine is constantly pouring cold water. If the valve has lost its technical characteristics, then water will continuously flow into the washing machine. It doesn’t even matter if the machine is on or off. This will greatly increase the consumption of cold water. The inlet valve cannot be repaired. You need to purchase a new one from the store and install it in the system.
Control unit failure
If the washing machine constantly draws water and the reason for this is the electronic control unit, then it is necessary to consult with a professional. Don’t bother checking and repairing it yourself. You can permanently break electronics if you do not have the necessary knowledge and skills. If there is a breakdown in the control unit, then most often it is not repaired, but a new one is installed.
If your washing machine constantly pumps water into the tank, then this is a serious breakdown in which it is impossible to use household appliances. If you do not figure out in a timely manner what is causing the incorrect operation, then you can wait until the washing machine fails completely, and its repair will become very costly, or even impossible. Therefore, at the first “call”, immediately start looking for the cause of the breakdown and ways to eliminate it.
