The situation when in washing equipment, after selecting a washing program, the drum is filled with water and its drainage is activated, and the loaded laundry remains wet and poorly washed, it is necessary to study in detail, since there are several reasons for such a failure. If the washing machine fills with water and immediately drains, it is necessary to diagnose its main components, since the cause of this could be any malfunction. Let's look at a number of breakdowns of washing machine units that cause it to not work correctly.
Reasons why the washing machine takes in water and immediately drains it
Let's describe the most common problems:
- sewer clogged;
- problems with the control system;
- the drain valve is faulty;
- problems with the performance of the water level sensor.
All breakdowns that cause the washing machine to begin draining the collected water, deviating from the specified washing program, must be eliminated, since they can provoke other serious malfunctions of equipment elements or cause liquid leaks.
What happens if this problem is not corrected in time?
Sooner or later, any washing machine begins to function incorrectly. In our case, the process of washing clothes will simply be impossible.
It is worth noting that the machine may not function correctly, disrupting the washing process, either once or repeatedly. If the reason for such operation of washing equipment is not established in time, the consequences can be unpredictable: from banal breakdowns and deterioration in the quality of washing, ending with a short circuit or flooding of the apartment.
Causes of malfunction
Why does the washing machine start to work incorrectly and drain the collected water? Let's describe the most common reasons for this.
Incorrect installation of the washing unit and its connection to the communication line
First of all, there is no need to panic, since the reason that the washing machine drains water after turning on the washing mode may turn out to be very banal and self-removable. It is quite possible that the washing equipment was simply installed incorrectly. In order to correctly adjust its position, you need to become a little familiar with the water supply process.
Water is supplied directly to the tank and pumped out of it using a special pump. For example, water may leave the washer drum if there is no plug on the drain hose or does not hold well.To prevent water from flowing out by gravity, the drain hose of the washing machine should be located at a height of 600-700 mm from the floor level.
If the washing machine is incorrectly connected to the communications, the described problem may occur, so we recommend that you pay attention to this first.
There is a blockage in the sewer
Another possible reason why the washing machine begins to fill and drain water after selecting a wash program is a clogged drain. This can be eliminated after a complete and high-quality cleaning of the sewer system.
But there is another method. To do this, simply disconnect the washing machine drain hose from the sewer pipe and place it in the bathtub or washbasin to more effectively drain dirty water during the washing process.
The pressure switch has failed
If the washing does not start, while an insufficient amount of water enters the machine tank and the draining process immediately starts, it can be judged that the water level sensor (pressostat) has failed. This element is necessary to control the water level in the washing machine tank. Usually it fails after a voltage drop or moisture. The following signs indicate a malfunction during operation of the washing machine:
- continuous supply of water to the washing drum;
- insufficient water level;
- a large amount of water in the drum;
- The spin function does not work well, the laundry remains quite wet after washing;
- presence of a small amount of water in the drum after completion of work.
If the washing machine gives an error immediately after starting the washing process, this may also indicate a failure of the pressure switch.
The following positions are provided for the water level sensor:
- empty drum;
- full drum;
- overflow of water.
When the washing program starts, water is supplied to the drum; if the sensor is faulty, the electronic control unit detects this as an overflow, the inlet valve closes, and the process of draining liquid from the tank starts. If the malfunction is not corrected, the washing machine will continue to malfunction whenever it is turned on. There is only one solution: replacing the water level sensor. This element is not that expensive, so there is no point in trying to restore its functionality.
Important: each washing machine model has its own type of water level control sensors. This suggests that the pressure switch for Bosch will not fit on Samsung. It is imperative to take this point into account when purchasing a part.
The drain valve is broken
If the drain valve fails, water will constantly flow into the drum. This problem can be corrected only by completely replacing the part.
Before you begin troubleshooting, you must turn off the power to the washing machine. If the equipment has horizontal loading, the drain valve is located under the top cover. To get to it, you need to remove it. On top-loading washing machines, the valve is located at the bottom, so the side panel must be removed to allow full access to it. You should select an identical part to avoid problems with its installation in the future. In addition, you need to purchase several clamps to connect the hoses.
Replacing a failed drain valve is carried out in the following sequence:
- Remove all wires and hoses from the inoperative valve.
- The valve can be secured using latches that need to be bent, or self-tapping screws (they need to be unscrewed).
- Remove the non-functioning drain valve.
- In reverse order, install the new part and connect hoses and wires to it.
- We put the panel back.
After replacing the valve, the washing process should occur in accordance with the program specified by the user and without any failures.
Control module malfunction
If the control module is faulty, then when the wash starts, the process of draining water from the machine tank starts. This occurs due to a malfunction of the ECU, which generates incorrect commands. If the washing machine has a display, it may display error codes that can be deciphered by having the instruction manual at hand.
In case of such a problem, you should turn off and turn on the washing machine again. If the water continues to drain, you should contact a specialized service center to diagnose the control module and eliminate all problems. We do not recommend trying to disassemble the washing machine yourself to fix this problem, since such actions can only aggravate the breakdown. Only a highly qualified specialist can restore the control module’s functionality.
Self-removal of the causes of the malfunction
You can correctly determine the cause of the malfunction by performing a full diagnostic of all units and components of the washing machine. To eliminate most problems, you will need the help of a qualified technician, since independent intervention can only cause harm.
Any incorrect operation of the washing machine is evidence of the presence of certain malfunctions of its components and assemblies, which must be eliminated. If the washing machine starts to fill with water and immediately drains, you need to stop its operation so as not to waste electricity, water and washing powder. In this case, the washing will turn out to be of poor quality, so there is no point in continuing it further. A reasonable option would be to eliminate existing faults and restore the functionality of washing equipment. In addition, there is a risk of flooding of the apartment and damage to property as a result, since the drum of the machine may be overfilled with water due to its improper supply. This malfunction requires mandatory elimination.
You can independently reconnect the washing machine if it was installed incorrectly, clear a clogged drain, and carry out minor repairs that do not require special equipment and tools.
What is not recommended to do on your own?
In most cases, even when the breakdown has been identified correctly, experienced technicians do not recommend fixing it themselves, since this can only aggravate the situation, which will lead to an increase in the cost of repairs. Let's list those breakdowns that you should not try to fix yourself:
- Restore the integrity of the drum.
- Replace the drive belt.
- Restore the functionality of the intake or exhaust valves, change them.
- Change the water level sensor (pressure switch).
- Perform any work related to electronics.
- Replace or repair the control module.
- Try to restore the integrity of the hoses.
- Replace the pump or repair it.
Conclusion
We do not recommend seeking help from random craftsmen whose qualifications and work experience are unknown. In addition, such a specialist will not provide adequate guarantee of the quality of his work, and in the process of troubleshooting, he may cause more damage to the washing machine.
Each manufacturer of household appliances gives certain recommendations regarding its maintenance and repair. There are certain regulations for carrying out measures to restore operability, which provide for the replacement of failed parts only with original ones suitable for this model. This means that the washing machine can be equipped with those elements that the manufacturer specifies in the list. Otherwise, its normal functioning after repair remains in doubt.
The cost of all repairs will depend on their complexity, volume and prices for replacement parts. It can be correctly determined only after diagnostics are carried out, during which the malfunction is identified.
