The situation when LG washing machine begins to vibrate strongly, jump on the floor or make rumbling sounds during the spin cycle, familiar to many owners of household appliances. Instead of the usual hum of the motor, you hear noise that can wake up your neighbors, and the equipment itself risks “drifting” to the opposite corner of the bathroom. This is not just an irritating factor, but also a signal that centrifugal force inside the drum has become out of control, which can cause serious damage.
Before calling a technician or looking for a service center, it is necessary to carry out an initial diagnosis, since in most cases the problem lies in improper installation or simple overloading of laundry. Vibration can be caused by both external factors and internal mechanical faults, such as wear of bearings or shock absorbers. Understanding the nature of sound can help you save time and money by determining whether a complex repair is required or a simple adjustment is sufficient.
In this article we will analyze in detail all the possible reasons for the unstable operation of LG units, from simple operating errors to complex technical failures. You will learn how to correctly level equipment and check the condition counterweights and diagnose the condition of the bearing assembly without disassembling the housing. A competent approach to the problem will extend the life of your device.
Installation rules and initial diagnostics
The most common reason why washing machine jumping when spinning, this is an incorrect setting. If the body of the equipment is not strictly horizontal, the center of gravity shifts, and at high speeds the drum begins to hit the walls. The floor in the bathroom is often uneven, and slippery tiles only enhance the sliding effect. Therefore, the first step should always be to check the stability of the supports.
Pay attention to the shipping bolts. These are special clamps that hold the tank stationary during transport so that it does not damage the internal components. If they are not unscrewed before the first start, depreciation will not work, and the machine will shake with enormous amplitude. There are usually four bolts located on the back wall, and their presence is a critical error that can be easily corrected.
⚠️ Attention: Operating the washing machine with the transport bolts not removed is guaranteed to destroy the tank and damage the heating element within several wash cycles.
Use a building level to check the position of the housing. Place it on the top cover of the machine and check the readings along the front and sides. If the air bubbles are not strictly between the marks, you need to tighten the adjustable legs. Rotate them clockwise to raise the angle or counterclockwise to lower it, achieving a perfect horizontal position.
☑️ Installation diagnostics
After adjustment, be sure to tighten the locknuts on the legs to secure their position. If this is not done, the legs may spontaneously unscrew during vibration, and the machine will warp again. Make sure all four supports are firmly seated on the floor and do not wobble.
Operating errors and laundry distribution
Often the cause of excessive noise lies not in a breakdown, but in a violation of loading rules. LG washing machines are equipped with a balancing system, but it is not omnipotent. If you've loaded one heavy item, such as a wet blanket or jacket, it may clump together as you spin. This causes drum imbalance, which the machine tries to compensate for, but with a strong distortion, beating begins.
Overload also has a negative impact. Throwing more laundry into the drum than specified in the instructions will create excess pressure on the bearings and make it difficult for items to be distributed evenly. The wet fabric becomes heavy, and the centrifugal force presses it to one side, forcing washing machine vibrate. Underloading is also harmful: one single item cannot be distributed evenly over the walls of the drum.
To avoid problems, try to form a uniform ball of linen. If you wash large items, add a few small items to balance them out. Do not fill the drum to capacity - there should be a palm of free space between the laundry and the top of the drum. Compliance with the weight standards specified in the model passport is critical for the long life of the equipment.
Wash down jackets and bulky items in special bags or together with tennis balls - this will help distribute the load and improve the quality of the wash.
Damage system malfunctions
If the installation is done correctly and the laundry is distributed correctly, but the vibration continues, the problem may lie in the wear of the shock absorbers. These parts dampen the vibrations of the tank during spinning. Over time, the lubricant in them dries out, or they simply lose their properties, ceasing to resist movement. As a result, the tank begins to shake freely, hitting the body.
You can check the condition of the shock absorbers visually and tactilely. To do this, you will need to remove the top and front covers of the machine. Try pressing down on the tank and letting go. If it bounces like a ball and sways several times, the shock absorbers are faulty. Serviceable parts should firmly return the tank to its original position without inertia.
| Symptom | Probable Cause | Test method |
|---|---|---|
| The car jumps forward a lot | Wear of front shock absorbers | Pressing the tank from above |
| Clunking sound when turning | Bearing failure | Rotating the drum by hand |
| Vibration only at high speeds | Imbalance or counterbalances | Checking the download |
| Creak and friction | Foreign object entry | Inspection of the space between tanks |
Replacing shock absorbers is a simple procedure, but requires partial disassembly of the body. New parts will be returned suspension stiffness and eliminate the beating. Do not ignore this repair, as repeated impacts of the tank against the body can cause cracks in the plastic parts or damage to the wiring.
Problems with counterweights and their fastening
Counterweights are heavy concrete or cast iron blocks mounted on top and sometimes in front of the tank. Their task is to balance the weight of wet laundry and dampen vibrations. If the counterweights are loosened, they begin to knock on the tank or body, creating a characteristic rumble. This often happens after transportation or long-term use with constant overload.
To diagnose, you need to remove the top cover and inspect the upper unit. The bolts holding the counterweight must be firmly tightened. If you notice play or visible gaps, they need to be eliminated. Sometimes the concrete block itself may crack, which will require its replacement, since gluing in this case is ineffective and dangerous.
⚠️ Attention: Before tightening the counterweight bolts, make sure that there are no distortions between the concrete block and the tank, otherwise the plastic tank may be damaged when tightening.
It's also worth checking the bottom of the machine, where there may be an additional counterweight (depending on the LG model). Getting to it is more difficult; you often need to tilt the car or remove the bottom. Loosening of the lower fastening causes strong vibrations of the entire structure, especially at the beginning and end of the spin cycle.
How to distinguish the knock of a counterweight from the knock of a bearing?
The knock of the counterweight is usually louder and more rhythmic, coinciding with the rotation speed. The sound of the bearing is more of a hum, howl or grinding noise that increases with increasing speed and does not stop immediately after the motor stops.
Bearing wear
The most serious and costly problem is bearing failure. These elements ensure smooth rotation of the drum. When they wear out, play appears and the shaft begins to wobble. This causes severe vibration that cannot be eliminated by adjustment. A characteristic sign is an increasing hum or howl during the spin cycle, reminiscent of the sound of an airplane taking off.
You can check the bearing by opening the door and sharply turning the drum by hand. If you hear a metallic crunch, grinding sound, or feel roughness in rotation, the diagnosis is confirmed. Also pay attention to the hatch seal: if rusty water oozes from under it, it means that the oil seal is leaking water, and the bearing is already being destroyed by corrosion.
Replacing bearings in LG washing machines often requires replacing the entire tank assembly, since in many modern models it is non-separable. This is a labor-intensive process that requires complete disassembly of the machine. Ignoring bearing noise can cause the shaft to seize and burn out the motor.
Foreign objects and debris
Sometimes the source of vibration is ordinary debris caught between the inner and outer tank. Coins, buttons, bra wires, or small pieces of clothing may become stuck in the heating space or near the pump. They make noise as they rotate and can cause wobbling if they get stuck in the wrong place.
To remove the item, it is often enough to remove the drain filter or pipe. In more difficult cases, you will have to remove the heating element (heating element) through the hole where it is installed and try to remove the debris with your fingers or long-nose pliers. Be careful not to push the object further into the pump impeller.
Regular cleaning of the drain pump filter is a mandatory procedure that will help avoid not only vibration, but also problems with draining water. Do this every 3-4 months or whenever there are signs of difficulty draining.
A foreign object between tanks is a common cause of local knocking, which can be easily eliminated without replacing expensive components.
Frequently asked questions (FAQ)
Why does my new LG machine vibrate during the first wash?
Most likely the shipping bolts were not removed. Check the back wall: there should be 4 bolts that need to be removed and saved. Also make sure that the machine is level and the legs are secured with locknuts.
Is it possible to wash if the machine vibrates a little?
Short-term vibration when accelerating is acceptable. But if the machine constantly jumps, hits walls, or makes loud noises, you should stop using it. This will lead to the destruction of other components, such as bearings or shock absorbers.
How do you know when it's time to change bearings?
The main symptom is an increasing hum during the spin cycle and play in the drum. If you feel roughness or hear a metallic grinding sound when turning by hand, the bearing assembly requires replacement.
Does the bathroom floor affect vibration?
Yes, it has a significant impact. Wood floors can resonate and slippery tiles can allow the machine to move. Use an anti-vibration mat or foot pads if the floor cannot be leveled.
