Water sensor malfunctions in the automatic washing machine | What are the causes and solutions?

When will this washing machine stop and get my clothes clean effortlessly? The question remains the most frequently asked question in the minds of its users, especially with the frequent suffering of water sensor malfunctions in the automatic washing machine, which mainly controls the water reaching the drum, but some have never been exposed to such malfunctions, and they do not know the importance of the water sensor. Introducing it, and about possible malfunctions on washing machines because of it. 
Water sensor function
It is an important component of automatic washing machines, as it controls the level of water that reaches the washing machine drum, according to the program chosen by the user, and water is of great importance in the laundry cycle, and therefore the sprayer - as it is sometimes called - plays an important role in This process, and the water sensor malfunctions in the automatic washing machine vary according to the extent of damage and damage to which it has been exposed, so it is one of the important tools that must be maintained. The water sensor is called by many names, such as the water balance, the water level switch, or the water pressure switch in the washing machine, but the name by which it is often known is Al-Bercher, and is often located at the top of the washing machine, specifically under the drum cover, and there are many types And it varies from one washing machine to another. 
Water sensor types
There are two main types in terms of general classification, and almost no automatic washing machine is devoid of one of them. The first type is the normal one with a mechanical timer, which is found in many models of washing machines, and the second type is the electronic sprayer, which is found in digital washing machines, which is considered more accurate. And efficiency than its predecessor, and controls the water in a way that allows several levels of it, and provides the opportunity for the washing machine drum to obtain it during the washing cycle.
How the normal water sensor works
Al-Burcher is originally a switch that allows electricity to pass or not, and thus allows it to control the water level in the drum. Its design consists of three connection points, they can be given numbers 11 - 12 - 13, in the normal situation, point 11 is connected to point 12, and when Choosing the appropriate program for the washing machine, the two previous points are separated, and point 11 is connected to point 13. In the event that the washing machine needs water, the electronic timer starts sending electricity, and the sprayer allows it to pass so that the water enters the drum, and when the appropriate amount of water is obtained to complete the washing cycle, he Al-Brusher disconnects the electricity from the water inlet valve, and allows the operation of the heater and the washing machine motor, by separating the communication between points 11 and 12, and reconnecting point 11 to point 13. The other two links. 
Water sensor malfunctions in the automatic washing machine
It is customary when the washing machine finishes the washing cycle, the pump expels the water outside the washing machine, until the spinning phase begins, and the sprayer supervises the expulsion of water, and therefore any malfunction in it makes the washing machine lose its ability to finish the washing cycle, and even causes many other malfunctions that The washing machine is damaged, which will be covered in detail in the following lines, and includes the following: 
The washing machine draws water constantly
The washing machine loses its ability to control the amount of water it needs, in other words, it continues to receive water continuously without interruption, which is contrary to normal for the people to cut the connection between points 11 and 12, to connect points 11 and 13, until it starts leaking from The door of the washing machine, or the soap drawer, or even the lower or rear parts of the washing machine, through the different connection hoses, in case it has cracks or cuts. It is possible that the cause of the malfunction is a rupture of the hose or bloating of the hose, meaning that there are holes in it that allow it to drain air, and therefore the air pressure in the key will not rise, which will lead to the continued passage of electricity to the water inlet valve, and not reaching the engine, and this explains the continued filling Washing machine drum with water. 
The washing machine failed to spin
The spinning stage is the last stage in the washing cycle, and it begins after the washing machine gets rid of the water inside the drum, through the ejection pump, which disposes of the water through the drain hoses into the drain stream, but when the sprayer malfunctions, points 11 and 13 remain in contact, which It means that there is water in the washing machine drum, even if it is disposed of, and therefore it will not be able to reach the spinning stage, in light of the fact that the timer did not send electricity to the motor based on the human signal to it that there is water in the washing machine drum.
The washing machine does not draw water
This malfunction is related in its meaning to the malfunction of the water sensor that was mentioned in the first lines, the pressure switch has been suspended on the connection of the two ends to each other 11 and 13, and therefore the washing machine will not need water after the drum is full, so it will start spinning and working normally according to the program that was chosen This means that the washing machine will not draw any other water due to this malfunction that occurs in old washing machines, which depend on the mechanical timer. As for the newer models, the error code appears on the electronic front washing machine screen, and refrains from working until the malfunction is fixed. 
/> The washing machine draws water abnormally during the wash cycle
Sometimes the washing machine continues to work without an increase in the water level, so it is likely that the clothes have absorbed large amounts of water, which helped the level to drop, and thus the sensor was affected and points 11 and 12 returned to the connection, and therefore the washing machine needs to draw more water to complete The washing cycle, however, with an excessively high level, this means that there is a slight air leak inside the water sensor, due to the lack of tightness of the hose in the burr hole, or the presence of a hole or a simple crack in it. The importance of the water sensor cannot be overlooked.
