The situation when the washing machine LG vibrates strongly during spinning, familiar to many owners of this equipment. Instead of calmly completing the cycle, the device begins to “jump” across the floor, make a frightening hum, and even move from its place. This is not just an irritating factor, but also a signal of possible technical malfunctions or operational errors.
Ignoring the problem can lead to more serious consequences, such as damage to the floor covering, breakdown of neighboring furniture, or failure of the internal components of the machine itself. Vibration is destructive to mountings and electronics. Therefore, it is important to quickly identify the source of the problem and eliminate it.
In this article, we will examine in detail the main causes of excessive shaking, ranging from simple installation errors to complex component repairs. You will learn how to carry out primary diagnostics yourself and in what cases you should call a specialist. Understanding the nature of noise can save you time and money.
Initial diagnostics: installation and transportation bolts
The first thing you need to check if your washing machine vibrates a lot, is the presence of transportation bolts. These elements fix the tank inside the case during transportation so that it does not dangle. If they are not unscrewed before the first use, the drum will become rigidly locked, causing extreme shaking and possibly breaking the mechanism.
There are usually four of these bolts, and they are located on the rear wall of the case. To remove them, you will need a wrench, which comes with the equipment. After unscrewing, the holes are closed with plastic plugs. If the machine has already been used before, you can skip this point, but it won’t hurt to double-check.
⚠️ Attention: Operating the washing machine with the transport bolts screwed in can lead to rupture of the tank or breakdown of the motor in the first minutes of operation.
The second important aspect is level installation. Even a slight misalignment causes the drum to beat at high speeds. Check that all four legs are firmly seated on the floor. Adjust their height by rotating counterclockwise or clockwise until the body is stable.
After adjustment, be sure to tighten the locknuts so that the legs do not become loose during operation. Try rocking the machine diagonally: if it stands solidly, then everything is in order with the installation. An unstable foundation is a common reason why equipment “leave” from its place.
☑️ Check before launch
Influence of gender and quality of laundry load
Excessive vibration often occurs due to the nature of the floor covering. If the washing machine is installed on slippery tiles or linoleum, it may move during the spin cycle. In such cases, it is recommended to use special anti-slip mats or footrests that dampen vibrations.
However, proper loading of laundry is equally important. Washing machine LG equipped with a balancing system, but it is not omnipotent. If you load too few items (such as one heavy jacket), the drum will not be able to distribute the weight evenly, causing an imbalance.
On the other hand, overload is also dangerous. Exceeding the maximum weight of dry laundry specified in the instructions leads to the fact that the wet fabric creates excess pressure on the bearings and shock absorbers. As a result, the machine begins to jump and rumble.
Distribute things evenly throughout the drum. If you're washing larger items, like bedding, add a few towels to balance out the lump. This will help shock absorbers effectively dampen vibration.
Depreciation system malfunctions
If everything is fine with installation and loading, the reason lies inside the case. The main unit responsible for damping vibrations is shock absorbers. They connect the tank to the lower part of the body and wear out over time, losing their damping properties.
You can check their status manually (after disconnecting the machine from the network). Open the hatch, push the top of the tank through the loading hatch and release. If the tank bounces like a ball and does not calm down for a long time, the shock absorbers require replacement. In good condition, the tank should return to its original position immediately, without inertia.
⚠️ Attention: When replacing shock absorbers, replace them in pairs, even if one of them appears intact. Different degrees of wear will cause the tank to misalign and cause repeated vibration.
It is also worth inspecting the springs on which the tank is suspended. They may stretch or come off their fastenings. Weak springs allow the tank to dangle too much, which is especially noticeable when spinning at high speeds. Replacing these elements usually returns the equipment to its former silence.
How to replace shock absorbers?
To replace shock absorbers, you need to remove the top and rear housing covers, disconnect the clamps and cuff to gain access to the tank. Then the shock absorber fastenings are unscrewed from the bottom and top. Installation of new parts is carried out in the reverse order. It is important to use original spare parts or high-quality analogues.
Bearing and bushing problems
The most serious mechanical problem is bearing wear. If you hear not only a knock, but also a characteristic hum, similar to the sound of an airplane taking off, which intensifies as it picks up speed, most likely the problem is the bearings. They ensure smooth rotation of the drum.
Bearing failure is often accompanied by drum play. You can check this by opening the door and shaking the drum up and down. If noticeable free play is felt or a knocking noise is heard, the bearings or bushing (on models with a one-piece tank) have failed. This requires complex repairs involving disassembling the tank.
In modern models LG Often a non-separable tank is used, where the bearings are pressed. In such cases, the tank assembly is changed or a complex procedure is performed to press out and press in new bearings with the installation of an oil seal. Ignoring the problem will cause the rotor shaft to begin to rust and may break.
| Symptom | Probable Cause | Difficulty of repair |
|---|---|---|
| Noise when spinning, vibration | Bearing wear | High |
| Car jumping, knocking | Shock absorber malfunction | Average |
| Moving from place | Legs slipping | Low |
| Metal clang | Foreign object entry | Average |
Worn counterweights and foreign objects
The concrete blocks attached to the front and back of the tank are called counterweights. They are necessary to weight the structure and compensate for centrifugal force. Over time, the fastenings may become loose and the concrete will begin to bang against the body or the tank itself, causing a lot of noise.
Check the tightness of the bolts holding the counterweights. If the concrete is cracked (as happens with impacts or defects), it must be replaced, as pieces can break off and damage other components. A crack in the counterweight changes the center of gravity, causing imbalance.
Another common but common reason is small objects getting into the space between the tank and the drum. Coins, bra wires, and buttons can get stuck and create wobble when rotated. Try shining a flashlight through the holes in the tank or removing the heating element to visually inspect the cavity.
Use a magnet with a long string to try to remove metal objects from under the drum without completely disassembling the machine.
Electronics failure and calibration
Sometimes the problem lies not in the mechanics, but in the “brains” of the device. Washing machine LG may not correctly determine the weight of the laundry or the position of the tub due to sensor failure. In this case, the calibration procedure helps, which resets the settings and teaches the module to work again with the current parameters.
To start calibration, you usually need to press a certain combination of buttons (depending on the model, often this means holding down the “Spin” and “Temperature” buttons when the machine is turned off). After activating the mode, the machine draws water and spins the drum, reading the data.
If the problem persists after calibration, the rotor position (Hall) sensor or the control module itself may be faulty. In such cases, diagnosis requires professional equipment. Replacing electronics yourself without experience can make the situation worse.
A soft reset and calibration is the first step if there is no obvious mechanical damage and after the installation has been checked.
When you need to call a specialist
Not all problems can be fixed by yourself. If you have checked the bolts, legs, shock absorbers and counterweights, but the washing machine continues to vibrateThe problem is probably deeper. Replacing bearings in a permanent tank or repairing a control module requires special skills and tools.
It is also worth contacting a specialist if the machine is under warranty. Opening the seal yourself and violating the integrity of the case will void the manufacturer’s warranty. It is better to entrust repairs to an authorized service center.
⚠️ Attention: If you are not confident in your abilities when disassembling equipment, stop at the diagnostic stage. Improper assembly may result in leaks or short circuits.
Timely repairs extend the life of household appliances. Don't let things get to the point where you have to throw away the machine. Regular maintenance and proper operation are the key to the long service life of your LG.
Is it possible to operate the machine if it vibrates a little?
Short-term vibration when picking up speed is acceptable, but constant shaking during spinning is unacceptable. This will lead to the destruction of the case, broken fasteners and failure of the electronics. Operation in this mode reduces the service life of the device significantly.
How often should shock absorbers be replaced?
The average service life of shock absorbers is 5-7 years with active use (2-3 washes per week). However, when overloading or washing heavy items (carpets, shoes), they can wear out faster, after 3-4 years.
Why does the machine vibrate only during the spin cycle?
During the spin cycle, the drum rotates at maximum speed (800-1200 rpm). Any imbalance, wear of parts or poor installation is manifested precisely under the influence of centrifugal force, which is unnoticeable at low speeds.
Does water hardness affect vibration?
Water hardness itself does not cause vibration. However, scale that forms on the heating element can break off and get between the tank and the drum, causing imbalance and knocking. Therefore, regular descaling is beneficial.
