A washing machine is a sophisticated electronic appliance. And as is often the case with all household appliances, it is also prone to breakdowns. Sometimes a washing machine may malfunction for no apparent reason. And then what to do? Call the wizard? But, as experience shows, in some cases, you can do without the help of a specialist. If, for example, your washing machine constantly drains water, then some practical tips and tricks may come in handy. Following them, you can correct the situation without the help of a wizard.
Symptoms of breakdowns of automatic washing machines
To determine that the washing machine is constantly collecting and draining water can be quite easy. First of all, it will immediately become noticeable that the washing time has increased dramatically. Sometimes the machine suddenly freezes, as if pondering the situation. At this moment, you just need to listen to the sounds coming from her womb. Having waited a little, it will be heard how, after the abstraction of water, its discharge into the sewers will follow. What is behind this breakdown and how to eliminate it?
The main causes of failure
Several reasons why the washing machine may not drain water correctly:
- incorrect connection of the drain to the sewer;
- blockage of the sewer itself;
- damage to the drain valve;
- malfunction of the water control level;
- crash or breakdown of the software module;
- program malfunction;
- oxidation of the contacts of the sensors.
Drain the machine incorrectly connected to the sewer
One of the reasons why the washing machine is constantly draining water is the incorrect drain connection. A specialist should be involved in connecting the washing machine, but often in order to save money, the owner himself performs this work. Well, if he follows the advice of the instructions, and if not, then this can turn into sad consequences. The height at which the drain hose should be at least 80 centimeters from the floor. If the hose is thrown vertically downward, then due to the pressure of the water, a self-suction effect may occur, and it will constantly drain into the sewer. To avoid this, read the installation instructions carefully before connecting the machine.
Sewer riser clogging
This effect may occur if you live on the lower floors of a multi-storey building. Residents living on floors above throw everything into the sewer, clogging the drain riser. Then, a vacuum is created from the bottom of the blockage, which sucks water from the washing machine with force. Especially this problem is the Indesit washing machine, constantly draining the water and adding it back.
To avoid such an effect and such a problem, you need to disconnect the drain hose from the sewer, try to fix its end on the sink or toilet. Then, together with water, air will enter the system and there will be no vacuum in the sewer. If the hose is short and does not reach the sink or toilet bowl, then you can simply throw it in a bucket or tank, which, when filled, pour into the same sink.
Damage to the drain valve
All modern washing machines have a drain valve. It prevents spontaneous discharge of water. As befits all electromechanical devices, the valve may break. There can be several reasons: burnout burnout, moisture ingress, aging of the membrane and deterioration of its properties. In such cases, it is customary to call a wizard to replace the valve. However, this can cost you a pretty penny, so every self-respecting man should be able to cope with such a problem.
To change the drain valve, you need to remove the front panel of the washing machine. Usually it is mounted on two or three self-tapping screws, which are located under the powder tray and under the pump cover. Next, you need to remove the valve by disconnecting it from the line and from the wires. Sometimes the drain valve and the pump are one, then you need to replace the entire pump. In the shops you can find any valve for your washing machine, and the prices there are lower. Now it remains only to install a new valve in place.
Broken water level tracking sensor
One of the reasons that the washing machine constantly drains water is the failure of the water level sensor. Water only reaches a certain level. The water level sensor monitors this. And if this sensor fails, then having reached a certain threshold, excess water will automatically be discharged to the outside. Unfortunately, such sensors are not repairable. It must be replaced by a native or similar. You can also find and purchase a sensor for controlling the water level in the store, and you can replace it yourself.
Broken software module
A software module is a complex electronic device. It includes a microcontroller, which controls the modes of the washing machine. The microcontroller may fail completely or partially if a high voltage is applied to it. If it burns out, then the machine will simply stop working. If partly failed, then this is fraught with malfunctions in the machine. Know, if the Zanussi washing machine constantly drains water in all modes, this may be one of the reasons. In this case, the module must be replaced.
Software module malfunctioning
Such a breakdown is also common. Defining it is quite easy, just look at the operation of the machine. It is necessary to turn on the machine in turn in each of the modes. If the washing machine constantly drains water only in one of the modes, and in the rest it works normally, then this is a malfunction in the microcontroller. In this case, you need to replace the entire module.
There are craftsmen who can restore the module by simply reflashing it. You can do it yourself, since there are a lot of instructions on this topic. Then you have to purchase a programmer, install special programs on your computer, which is also not very profitable. It is best to contact a specialist or service center for help.
Oxidation of sensor contacts
If the washing machine is constantly draining water, the cause may also be in the oxidation of the sensor contacts. Naturally, a washing machine is a source of high humidity. And the terminals at the ends of the wires that connect to the sensors are made of copper or aluminum. Moisture getting on these terminals leads to metal oxidation. As a result, contact disappears at the junction. Weak contact leads to a malfunction of the machine, including, may be one of the reasons why the washing machine constantly drains water. It is treated simply: you need to remove the terminal blocks from all sensors, a pump, a software module, just clean them with an emery cloth or file. Having collected everything back, you can enjoy the good work of the machine.
Conclusion
This article lists only some of the important breakdowns of washing machines. There can be much more: a strainer, a low voltage in the network, and so on. It is much more important that almost all kinds of malfunctions can be dealt with yourself, without calling the master at home or contacting a service center. You can save a lot by doing home repairs yourself. The main thing is that a person understands what he is doing and the tool is suitable. All you need is desire. But, there is a downside to self-repair. If the machine is under warranty, then you do not need to try to repair it yourself. This will invalidate the warranty, even if the damage is serious, you will be denied a free repair.
