Self-diagnosis of washing machine faults

In the event of a breakdown of household appliances, it is easy to call a competent specialist. But can he always deal with problems with skill, and will he not deceive you into paying for expensive repairs? That is why it is better to know how self-diagnosis of the washing machine is carried out: this will help save your time and money.

Sources of problems

In a situation where your home appliance signals any error or malfunction in operation, you need to refer to instructions. It briefly summarizes the most common breakage for this model and parts subject to wear.

In addition, among the current models, the function of self-diagnostics is widespread. For example, in devices from the company LG integrated system Smart Diagnosis, allowing to determine the malfunction without any special technical knowledge. If your machine is not equipped with such know-how, then it is possible to conduct a visual inspection and identify problems. Some of them do not require professional repair, but are caused by the banal non-observance of the device operation rules.

Before you start inspection or repair, make sure that the machine is disconnected from the network and plumbing.

The machine does not start

One of the most popular problems that can happen to your machine during operation. But do not panic, the reason for the failure to start can be not only the malfunction of the system. So, for example, the program may not start for the following reasons:

1. Lack of electricity - make sure that the outlet for connection to the power supply is working, check the operation of the switchboard and the integrity of the wire of the washing machine.
2. Start Button Problem - possibly, oxidation of contacts or critical failure of the button itself occurred. Check for damage.
3. Lid tightly closed or not locked hatch - make sure that the loading door is tight. The washing program will not be started if the special sensor does not receive a signal to close the lid.
4. Interference Filter Malfunction - in most machines, a device for filtering electrical noise is installed right behind the power cord. When it fails, it simply blocks access to electricity, preventing the device from turning on. Check how functional it is.
5. Electronic control module damaged - the so-called "brain" of the household appliance. If it fails, then you can not do without professional repair, in this case you will have to call a specialist.

Causes of drum problems

The problems with the drum of the machine can be very diverse, from the failure of the main engine to the failure of seemingly minor details.

Full stop drum

Motor crash - at the same time absolutely no sounds will be heard. Such a drum stop may indicate engine combustion. Check its windings, make sure they are not damaged.

TEN failed - The failure of the heating element may also be the cause of the failure.Usually, with this breakdown, the car issues a special signal to the control panel.

Problems in electronic control module - the main controlling element, without which no program will be launched. The machine will not respond to button presses. To fix your module, you will need to contact a specialist.

Breakage TENA

The drum stands still, but you can hear the hum of the motor.

In the space between the drum and the tank could get foreign object: the little thing forgotten in pockets can jam the work of rotating elements. You can solve this situation by removing the heating element and removing unnecessary items.

Motor failure - rupture or winding burnout motor leads to a loss of power, and he simply can not move the loaded drum. Check their integrity.

Brush wear in the motor - a typical problem of household appliances. The most wear part of the engine - brushes - require periodic replacement.

Seizure of bearing system - similar happens with worn bearings. This problem can only be resolved with the complete disassembly of a household appliance.

Broken electronic control module - One of the most serious damage.You can fix it only by reprogramming the module or replacing it with a new one. This type of repair is best left to professionals. Since the procedure requires special knowledge.

Single motor operation without drum rotation

Torn drive belt - In machines with indirect drive, there are often problems with belts. It is worth making sure of his condition. This can be done by removing the back panel.

Loose wheel - This is a part attached to the drum and connecting it to the belt. After a long use of the machine, the pulley begins to roll in place without rotating the drum.

The rotation of the drum in one direction only.

Here the problem lies in electronic control module. Malfunctions can knock his work and disrupt the rotation algorithm. In some machines, this function takes on a special board. They can also fail or burn out. Check their performance, and replace with new ones if necessary.

Unpleasant noise

After some time from the date of purchase, the machine may start making strange sounds. There are several reasons for this.

1. Foreign bodies, garbage, coins, forgotten in the pockets of clothes - all this can create strange sounds. Check the distance from the tank to the drum: there may have been foreign objects.
2. Malfunctions in the water discharge system or pump malfunction. Inspect the pump.
3. Out of order bearing system. Carefully inspect the bearings and check their wear.
4. Invalid location cars. Read the installation and adjustment instructions for the machine. Try to unscrew the legs to different heights.

All these problems require careful study of the internal parts of the machine, and sometimes call the wizard.

Bearing replacement

Not performing the spin function

Spin laundry can not be done for a variety of reasons, ranging from software failures and ending with mechanical damage. Consider the most common ones.

1. Wrong program running. Check which program you run, not all washing algorithms include spin. Study the instructions and enable the correct algorithm.
2. Drum congestion. If you have not calculated the weight of the laundry and loaded more into the drum than the design provides, then the spin mode will not start until the overload is eliminated.Also in modern models can be installed balance sensor. Unevenly distributed laundry creates an imbalance in the drum and prevents the spin from starting.
3. Breakdown in the drain system. The spin system will start only after removing the dirty water from the drum. Check the drain pump and nozzles for blockages and kinks.
4. Malfunctions in the tachometer. This is a special device that controls the number of revolutions of the drum. It is installed on the shaft of the washing machine, and fails with frequent use of a household appliance at the limit of possibilities. Check the mounting and wiring of the tachometer. Verify the integrity of the contacts.

As you can see, the diagnosis of a washing machine with your own hands is not something frightening and difficult, everyone can learn it. With proper care and timely replacement of parts, the household appliance will never let you down.
