If the washing machine stops spinning clothes, and after the end of the cycle the clothes remain wet and heavy, the problem most often lies in a clogged drain system or worn-out motor brushes. In such situations, the unit usually stops with water in the tank or goes into an endless drain mode, trying to remove the liquid before starting high speeds. Ignoring these symptoms can lead to failure of more expensive components, for example, a control module or heating element, so initial diagnostics should be carried out immediately after a failure is detected.
Some models automatically block the spin function if the imbalance sensor detects a strong shift of the laundry to one side of the drum. This is a safety mechanism to prevent the bearing assembly from beating and breaking, but if the machine refuses to spin even with a light load, the problem is not in the distribution of things. It is necessary to analyze at what stage the cycle stops: whether there is water in the hatch, whether the device makes humming sounds, or simply freezes without signs of life.
The first thing you should check is the drain filter, located at the bottom of the case behind the decorative panel. It is here that small objects, lint, buttons and coins most often accumulate, which impede the free passage of water. If the filter is clogged, drain pump is not able to quickly pump out water, and the automation does not give the command to spin the drum, since the liquid level inside is still high. To check, you need to place a flat container, unscrew the plug counterclockwise and clear the cavity of debris, then check the pump impeller for free movement.
If mechanical cleaning does not help and the water drains slowly or does not drain at all, the water itself may be faulty. drain pump. The cause may be a burnt-out motor winding or a jammed shaft by a foreign object that has passed deeper than the filter. In some cases, the impeller is intact, but the motor hum is completely absent, which indicates a lack of voltage or an open circuit. In such a situation it is required continuity test with a multimeter contacts suitable for the pump to rule out a problem in the wiring or control module.
Users often forget to check the drain hose, which may be pinched by the equipment body or clogged at the connection to the sewer. Even if the filter is clean, the water will not be able to escape if the corrugated hose is pinched or the sink siphon to which the unit is connected is clogged. It is necessary to disconnect the hose from the sewer pipe and lower it into a bucket, starting the drain mode: if the water flows freely, the problem is in the home sewer, and not in the machine.
⚠️ Attention: Before any manipulations with electrical components and the drainage system, be sure to disconnect the washing machine from the power supply. Water and electricity are a dangerous combination that can cause serious electric shock.
Motor malfunctions and brush wear
When a washing machine fills with water, washes, but does not enter the spin phase, wear and tear is often the culprit. graphite brushes commutator motor. These elements transmit current to the rotor, and over time they wear out, losing contact with the lamellas. At low speeds typical for washing, the engine can still work, but spinning requires high power, which worn brushes cannot provide, which is why the drum either does not spin or rotates jerkily.
To diagnose, you need to get to the engine by removing the back cover or disassembling the housing, depending on the model LG, Bosch or Indesit. A visual inspection will show the length of the brushes: if it is less than 1.5 cm, they need to be replaced. It is also worth checking the tightness of the brushes to the commutator and the condition of the springs, which may weaken and not provide the required pressure.
In some cases, the problem lies not in the brushes, but in an interturn short circuit in the motor winding or a malfunction of the tachometer. Tachometer controls the speed of rotation of the shaft, and if it transmits incorrect data to the control module, the electronics blocks the spin to avoid damage. The integrity of the windings and the resistance of the tachometer coil is checked using a tester, and if deviations from the norm are detected, the unit must be replaced.
How to check the tachometer
Remove the connector from the tachometer coil and measure the resistance. It should be within 60-70 Ohms. If it shows an open or short circuit, the part is faulty.
Drive belt and pulley problems
In belt-driven models, a common cause of lack of spinning is a stretched or slipped drive belt. If the belt has simply slipped off, it can be put back in place, but if it is stretched, it will slip on the engine pulley when trying to reach high speeds. As a result, the drum either stands still or rotates too slowly to create centrifugal force to remove moisture from the fabric.
Inspect the belt for cracks, abrasions, and rubber dust around the assembly. The tension should be such that when pressed with a finger, the belt bends by 1-1.5 cm. Excessive tension leads to rapid wear of the engine bearings, and weak tension leads to slippage and lack of effective spinning clothes.
It is also worth paying attention to the condition of the pulley, especially if it is plastic. In older models or with aggressive chemicals, the plastic may crack and the pulley will begin to rotate on the motor shaft. Metal pulleys are more reliable, but they can also become deformed if there is a strong imbalance. If the pulley is loose or has visible damage, it must be replaced along with the belt.
☑️ Belt drive diagnostics
Control module and sensors failure
Modern washing machines are controlled by sophisticated electronics, and if control module fails, it may not send a signal to start the spin cycle. The cause may be burnt triacs that control the motor, or broken contacts in the connectors. This is often indicated by a flashing spin indicator or a complete lack of response to buttons when the mode is on.
Water level sensor (pressure switch) also plays a key role: if it is “stuck” and shows that there is still water in the tank, although it has already been drained, the machine will not start spinning. Conversely, if the sensor does not see water, the cycle may not proceed correctly. The test is carried out by blowing through the pressure switch tube and testing its contacts when the pressure changes.
The table below shows common error codes associated with spin problems for popular brands. Deciphering the code helps to narrow down the troubleshooting and understand which particular unit requires attention.
| Brand | Error code | Description of the problem |
|---|---|---|
| Samsung | E5 / 5E | Problem with water drainage (clogging, pump) |
| LG | OE | Water drain time exceeded |
| Bosch | E18 / F18 | There is a problem with the drain or the hatch is open |
| Indesit | F05 | Water level sensor detected water |
| Electrolux | E20 | Water drainage problem |
⚠️ Attention: Repairing the control module yourself requires in-depth knowledge of electronics. If you are not confident in your abilities, it is better to contact a professional so as not to aggravate the situation and burn serviceable parts.
Mechanical damage and bearing wear
If, when you try to spin the machine, it makes a strong hum, similar to the roar of an airplane, and vibrates strongly, it is most likely out of order. tank bearings. Wear of the bearing assembly leads to play in the drum shaft, which causes it to warp and cannot rotate normally at high speeds. In this condition, the automation often emergency stops the program to prevent destruction of the tank.
You can check the condition of the bearings by opening the hatch and shaking the drum up and down. If free movement is felt or a metallic knock is heard, and rusty stains are visible from under the cuff, the bearings require replacement. This is a labor-intensive procedure, often requiring complete disassembly of the machine and replacement of the entire tank assembly if it is not dismountable.
Another mechanical cause could be a breakdown shock absorbers or weakening of counterweights. If the tank is not firmly secured, strong vibration occurs during the spin cycle, the imbalance sensor is triggered, and the machine slows down or stops. Check the integrity of the springs on which the tank is suspended and the tightness of the counterweight bolts.
Tip: To extend the life of the bearings, try not to overload the machine and evenly distribute the laundry before starting the spin cycle. Use descaling products regularly.
Software failure and improper operation
Sometimes a technically sound machine does not spin due to a simple glitch in the program or an incorrect choice of mode. For example, in the Delicate, Wool, or Hand wash modes, the spin function may be disabled or reduced to minimum by default. Check the settings of the selected program and, if necessary, add a manual spin option.
The electronic brain of the machine may freeze due to a power surge. In this case, rebooting helps: unplug the device from the outlet for 15-20 minutes, then turn it on again and start the “Drain and Spin” mode. If the problem was a software glitch, it should go away.
It is also worth mentioning the “Child Lock” function, which can block program changes, including adding a spin. If the corresponding icon is lit on the display, unlock the control panel according to the instructions for your model Samsung, LG or another brand.
Main conclusion: In 80% of cases, the reason for the lack of spinning lies in a clogged filter, wear on the motor brushes or a stretched belt. You can fix these problems yourself.
Frequently asked questions (FAQ)
Why does the machine hum during the spin cycle, but does not spin the drum?
A humming noise usually indicates that the engine is trying to start, but something is preventing it. Most often this is a stuck bearing, a foreign object between the tank and the drum, or a faulty starting capacitor (in asynchronous motors). It is also possible that the pump may become jammed.
Is it possible to operate the machine if it stops spinning?
It can be used, but it is not advisable. Things will have to be taken out wet and dried by hand or in a dryer. However, if the cause is a leaking bearing, further washing will lead to destruction of the shaft and tank, which will make repairs economically impractical.
What should I do if, after cleaning the filter, the machine still does not spin?
If the filter is clean and the water drains slowly, the problem may be in the sewer pipe or the pump itself (the winding is burned out or the impeller is broken). If the water drains quickly but there is no spin, check the belt, motor brushes and sensors.
Why does the machine spin only at low speeds?
This may be due to worn motor brushes that do not provide the required power, or a faulty control module. Also check if the “No spin” or “Easy iron” mode is selected.
How can you tell if the control module has burned out?
Signs: the machine does not respond to buttons, changes modes chaotically, knocks out traffic jams when turned on, or displays complex error codes related to the communication of nodes. Only a technician can make an accurate diagnosis after checking the board.
