The washing machine collects water to the desired level, but does not turn the drum, most often due to burnt out thermal heat, wear of the engine brushes or malfunction of the control module. In such a situation, the device may simply hum, make clicks or completely shut up after filling the tank, ignoring the command to start washing. The user sees a full tank of water and expects to spin, but the electronics block the start of the motor to prevent flooding or further damage to the nodes.
This behavior is typical for models Indesit, Bosch and LGwhere the self-diagnosis system detects a critical failure in the heating or rotation circuit. If you ignore the first signs, such as humming or no rotation when the pump is running, you can bring the engine to a wedge or burn out the simistor on the board. It is important to determine whether the heating is working right away, as in many washing algorithms the motor will not start until the water reaches a predetermined temperature.
Some models can simulate washing, slightly swaying the linen, but full rotation does not occur. This indicates that the program is running, but the physical force on the engine shaft is absent or insufficient to turn the loaded linen. We will analyze the main technical causes, diagnostic methods and ways to eliminate malfunctions on our own.
Engine malfunctions and brush wear
The most common reason for stopping rotation is critical wear of the graphite brushes of the collector motor. When the brush length becomes less than the permissible value, contact with the collector is broken, and the motor ceases to receive current. The washing machine may draw water, try to start the motor, hear a lack of reaction and go into error or simply stop the cycle. A characteristic feature is sparking inside the body and a specific smell of burns.
In some cases, the brushes still have a residual resource, but they are βhungβ in the guides due to moisture or dust. The engine is humming, trying to turn the shaft, but the drum is standing still. If you gently tap the engine body during a start attempt, it can earn short-term, which confirms the problem with the contact group. For repair, it is required to replace brushes with original or high-quality analogues corresponding to the parameters. density and size.
The engine collector can also be contaminated with graphite dust, which causes a short circuit between the lamellae. In this case, even new brushes will not provide stable work. It is necessary to visually inspect the collector: it should be clean, without black soda and chips. If the lamellae are blackened, a professional duct or replacement of the anchor will be required.
- π No spark: when removed brushes it is clear that the spring does not press the graphite to the collector.
- π Blunt: The motor hums, but the drum does not even make a jerk, which indicates a wedge or a break in the winding.
- π Smell: The smell of scorched plastic or electrics appears when you try to start.
- π Tricks: The drum is twitching in different directions, but can not gain momentum for pressing.
How to check brushes without disassembly
Remove the back cover of the car (if the model allows). When you turn your pulley, listen to the sound. If you hear grinding or uneven noise, the brushes are probably worn out. You can also estimate their length through the hole in the engine casing using a flashlight.
Problems with water heating and TENG
The algorithm of many washing machines provides for mandatory heating of water before the drum starts rotation. If you choose washing mode at 40-60 degrees, and the TEH (ten) burned out or covered with a thick layer of scale, the machine will endlessly wait for the temperature to rise. As a result, the illusion of breakdown is created: there is water, the program is running, but the drum does not turn, since the control module does not give a command to start the engine.
Check the heating by running the washing mode at 90 degrees and opening the hatch after 20-30 minutes (carefully so as not to scald). If the water is cold and the car continues to hum or just stand, then the TEN is faulty. The scale on the heating element acts as a thermal insulator: the water does not warm, the temperature sensor does not work, and the washing cycle freezes. In some models Electrolux or Candy This results in the issuance of an error code related to heating.
β οΈ Attention: If the TEN is running on the body, it can trigger an ultrasound or knock out traffic jams in the apartment immediately at the beginning of heating. In this case, the operation of the machine is life-threatening.
Replacement of TEN is a simple procedure, but it requires compliance with safety precautions. Before dismantling, you need to completely drain the water and disconnect the device from the network. The new heater should have the same power and length as the old one. It is recommended to check. heat-sensorIt is often built into the heater, as it could fail at the same time as the heater.
Failures of the control module and the simistor
The electronic control module is the βbrainβ of the washing machine, which supplies voltage to the engine and the TEN. If the simistor responsible for the engine chain burns down, or a track on the board breaks through, the engine will not receive a command to rotate. Externally, it looks like this: the water has accumulated, the pump has turned off, but silence. The module may attempt to give a pulse, as evidenced by clicks of the relay, but rotation does not occur.
A common cause of failure of the symistor is moisture on the board or a power surge in the network. In the case of direct-drive models, such as LG Direct Drive, the role of the control board is performed by an inverter module fixed directly on the tank. Its repair is more complicated and requires special knowledge in electronics. If it burns. squirrel or its wiring, the module does not see the revolutions and blocks the further operation of the program.
Diagnostics of the board visually often does not give results, since chips can look whole even with an internal breakdown. Requires a multimeter vertebrae of elements. If you do not have the skills to work with a soldering iron and electronic circuits, it is better to contact a service center. Independent soldering of the symistor without eliminating the cause of the breakdown (for example, poor contact) will lead to repeated failure.
Breaking or stretching of the drive belt
In belt-driven machines, the transmission of rotation from the engine to the drum is through a rubber belt. Over time, it stretches, cracks or tears completely. If the belt is off or torn, the engine will run (buzz), but the drum will remain stationary. This is one of the easiest and cheapest to fix problems.
To check, you need to remove the back cover of the washing machine. If the belt lies at the bottom of the body or hangs on a pulley, it must be replaced. When installing a new belt, it is important to correctly combine the brooks of the pulley and the belt groove. The skew will cause rapid wear and tear. It is also worth checking the state of the pulley: if it is loose-headed or has a backlash, the belt will fly off constantly.
Sometimes the belt is intact, but it is very stretched and slips on the pulley when loaded. In this case, the machine can start spinning, but when you set speed, the belt will start to slip, emitting a characteristic whistle and rubber smell. The drum will turn in jerks or stop completely. The stretched belt is not subject to restoration and requires mandatory replacement.
When replacing a belt, always clean the pulley of the engine and drum from rubber dust and dirt. This will improve grip and extend the life of the new part.
Bearing locking and mechanical spelling
If the engine is working, the belt is stretched, but the drum does not rotate even manually, so there was a mechanical jamming. This is most often caused by the failure of the bearings of the tank. Water with detergent penetrates through the omentum, washes out the lubricant and causes corrosion of the bearing. The shaft rusts and the drum jams dead.
Signs of bearing failure:
1. A strong hum or roar when pressed (harbinger of breakdown).
2. The lumpen of the drum (if you take the upper edge and sway, it walks relative to the tank).
3. Rusty streams on the back wall of the tank or on the cross.
Jamming can also occur due to foreign objects between the tank and the drum. The bones from the bra, coin or button can block the spin. In this case, the engine will buzz trying to turn the shaft, but the drum will not move. It is necessary to remove the TEN and through the resulting hole to check the space around the drum for the presence of foreign bodies.
