A common problem after installing a washing machine is a strong buzzing sound and even “bouncing” during the spinning process. The most likely cause is an imbalanced drum. The malfunction must be promptly eliminated - we are talking here not only about discomfort due to noise and knocking, but also about increased wear of components. The washing machine is being balanced to restore normal operating conditions. You can do this yourself, but to get a guaranteed result, it is better to turn to specialists.
The risk of imbalance is high if the rules for transporting the unit are violated, if it is installed incorrectly, or if it is placed on an unsuitable surface. If a problem has already arisen and you need to re-balance the washing machine drum, the Remontano specialists will help you sort it out.

Balancing the washing machine drum: instructions
Have you noticed that your washing machine has started to make a loud noise and jump during the spin cycle?
Perhaps the reason is that the drum is unbalanced. If you have such a problem, you need to solve it, because excessive noise and vibration not only disturb you, but also lead to wear on the parts of the washing machine. In earlier models, the imbalance leads to strong vibrations during the spin cycle. And modern models can stop if the system fails to restore balance.
Spring hangers for washing machine tank
The washing machine tub actually hangs in the air on two (four) powerful springs that hold it on the sides. Over time, metal fatigue sets in and one of the springs may burst. After this, the tank is actually lowered onto one of the shock absorbers, so there can be no question of any vibration damping.
It is very easy to identify this malfunction. Pay attention to the drum and how it stands in relation to the sealing lip of the loading hatch. If the cuff is deformed and the drum moves to one side, then the spring has 100% burst. To make sure of this, remove the top cover and look at the side springs, they are not covered by anything, and you will immediately see them.
Replacing tank spring hangers
Replacing the spring is very simple, you just need to measure it correctly. To do this, you can remove the surviving one and use a tape measure to measure the length and diameter. To change it, place the car on the back wall, then you can set the tank in the desired position and put on a new spring without any problems.

How to balance a drum with your own hands
Washing machine drum balancing is automatically built into modern models from Samsung, LG, Bosch, and Ardo. This additional feature is called "Imbalance Control". In this case, the system will not allow the washing machine to spin until the problem is resolved. To do this, the drum rotates in different directions, sometimes slowing down, sometimes accelerating.
If you set the spin to maximum speed, but the imbalance is not corrected, then the machine will significantly reduce the spin speed so as not to harm its parts. Or the spin cycle will be stopped altogether. In any case, you will get almost wet laundry out of the drum.
How to do balancing yourself? Proceed sequentially:
Top-loading washers make it easier to center laundry because you don't have to drain the water to open the door. If, after distributing the items, the washer shakes again during the spin cycle, check the balancing stones. They are located behind the front and rear panels of the SMA and are attached to the drum. Sometimes their fastenings become loose, leading to imbalance.
How to avoid imbalance
Make sure that you load the drum according to the norm for your washing machine. If the washing machine is designed for three kilograms of laundry, this does not mean that you need to fill the drum to capacity. It should be 2/3 full. And:
If you are just going to buy a washing machine, choose the load capacity in accordance with the number of everyday items to wash. If, when choosing a drum volume of 7-8 kg, you cannot collect enough for a daily load, washing once a week will not always be convenient.

Causes
Manufacturers of washing machines, using innovative techniques, strive to produce high-quality products that are as silent and convenient for the consumer as possible.
But natural vibration and slight shaking are observed in all brands and models of household appliances without exception.
The practice of operating household appliances has revealed the main reasons for “mobility” and increased vibration during washing.
Availability of transportation bolts
When connecting and installing a new washing machine yourself, there may be situations where the transport fastener was not removed.
In this case, the drum is not completely blocked and the fixing bolts prevent the free rotation of the drum mechanism, which causes damage to many parts and components.
Therefore, the first thing you should do is inspect the unit body and remove the shipping bolts of the washing machine.
Purpose of this function
In short, imbalance control in a washing machine is a timely response of the system to an imbalance occurring inside the machine. A special sensor detects uneven distribution of things in the drum or other reasons for deviation from the norm and sends a threat signal to the control board. The unit tries to solve the problem on its own, and if unsuccessful, stops the wash to avoid damage. Otherwise, the laundry crumpled on one side will cause jumps, which will lead to strong vibration, shock and mechanical damage to internal parts. The result will be failure of the bearing assembly, shaft cross and drum surface.
With functioning imbalance control, this will not happen. The sensor will immediately detect a deviation from the norm, reduce the rotation speed, reduce vibration, stop the cycle and give a warning sound. Afterwards, the owner will have to independently eliminate the cause of the imbalance, for example, open the door and evenly distribute things in the drum.
All modern washing machines with a spin speed above 1000 rpm are necessarily equipped with an imbalance control function.
It is better to carefully read the factory instructions after purchasing the machine and before starting the first wash. It describes recommendations for eliminating imbalances on a specific model, and also provides basic rules for operating the washing machine. For example, the main nuance that provokes excessive vibration is failure to comply with the permissible load. Do not forget to take into account that the capacity in kg indicated on the marking refers to cotton fabrics. Synthetic materials and wool products are somewhat heavier, so we strictly monitor the weight of the laundry we wash.
At the end of the wash I’m shaking all over, I don’t understand why...
The wash ends with a spin cycle. Many old machines bounce and rattle at this stage of operation when, for example, laundry gets bunched up. But modern models use technologies to help avoid this. Representatives of the largest washing machine manufacturers talk about them and more.

The car must have brains!
Vladimir Rozhkov, ATLANT: “in this matter, the main thing is the “brains” of the machine...” Today, almost all machines (their electronic modules) determine the uniformity of the distribution of laundry over the surface of the drum and, depending on the level of imbalance, make the required number of attempts to lay out the laundry, achieving little imbalance. Ultimately, the modules select the maximum spin speed: the greater the imbalance, the lower the spin speed.
Dmitry Serditov, BSH: “all modern machines are equipped with a function to control and suppress imbalance during spinning.”
The washing machine is not a “good horse”, and it should not gallop! In the standard case, the imbalance is determined by the uneven rotation of the drum using a tachometer. Advanced Siemens washing machines have automatic stabilization with a 3D sensor.
The system, consisting of a sensor and a microprocessor, accurately determines the position of the tank (and, accordingly, the drum with loaded laundry) relative to the body.
The time to detect imbalance is significantly reduced, noise and vibration are reduced, and the service life of the machine is increased. Having determined the imbalance, the machine takes measures to eliminate it.
Evgenia Suzdaleva, Mabe: “excessive vibration not only creates annoying noise, but also adversely affects the life of the machine.”
At the household level, when loading laundry, in order to create the correct balance at each point of the drum, in order to avoid incorrect distribution of the laundry, it is advisable not to exceed the maximum load, and if the load is small, to reduce the spin speed.
Machines equipped with a balance control function automatically control the balance of the drum during the spin cycle. Such a machine makes several slow movements of the drum in the opposite direction, unraveling the laundry and distributing it evenly.
If the imbalance is not corrected, the machine spins at the lowest speed or does not spin at all. Mabe engineers in Spain have developed an innovative ABS (Advanced Balance System) system with an electronic control for uniform distribution of clothes inside the drum throughout the spin cycle.
Installation and download rules
Kirill Burmistrov, ARDO: “First of all, you don’t need to load too much laundry and you should level the machine on a horizontal plane.”
If the washing machine is designed for a load of 5 kg, then do not try to tamp 7 kg in there just because it fits. Also, do not forget that each type of fabric has its own loading limit. For cotton it is, as a rule, more, for synthetics it is less, for wool it is completely minimal.
All numbers are written in the instructions, and if you read them in advance, you can avoid most problems with using the washing machine.
I wouldn't say that all old washing machines bounce and rattle. Half the time, excessive vibration is due to the machine not being level, which is why there are adjustable feet.
The main technology to avoid unwanted noise and vibration is automatic balancing. Our washing machines themselves distribute the laundry evenly, which allows you to get rid of unwanted effects.
Anastasia Godina, VESTEL: “it is necessary to install the washing machine correctly, and only on a hard floor, that is, level it and firmly fix the legs with locknuts.”
You cannot place the machine on a smooth tile: place a thin but hard rubber mat under it, otherwise the machine will “run away” during the spin cycle.
Imbalance control systems not only serve to reduce the noise and vibration of the washing machine during spinning, but also to increase operational reliability. Safety comes first.
The most common technology for determining imbalance is special software; new products include 3D sensors and active imbalance control systems, for example, electromagnetic dampers.
Alina Myshkina, Candy: “to avoid the problem of imbalance, you need to follow just a few simple rules: wash bed linen separately from other things (since it is usually duvet covers and pillowcases that are the “culprits” for uneven distribution of linen), do not exceed the permissible load and wash “heavy” items fabrics separately."
In addition, electronics allow you to monitor how the laundry is distributed in the drum.
If the laundry is bunched up and there is a risk of reducing the washing efficiency, the machine will make several slow revolutions of the drum, trying to distribute the laundry more evenly.
And it was right about the legs: the Candy company made all four legs of its washing machines adjustable.
Ivan Lavrentiev, Hansa: “for these purposes, our models use the technology of mounting the car body on three shock absorbers.”
As we know from the laws of physics, any object will find balance better on three points of support than on two or four.
Correct distribution of counterweights and, of course, electronics that monitor the occurrence of vibrations will help solve the problem.
Special design reduces vibration
Alexander Uzhgintsev, Miele: “in Miele washing machines, the task of reducing vibration during spinning is solved through many design features.”
The tank counterweight is made of cast iron; it does not wear out at the attachment points with the tank and has no play, unlike concrete structures.
The machine itself is quite heavy (about 100 kg), so the likelihood of it becoming unbalanced is significantly reduced. The tank has reliable shock absorbers (the same ones found on small-class professional Miele machines).
If the imbalance sensor is triggered, the machine tries to redistribute the laundry in the tub. The attempt will be repeated a maximum of three times, and if this fails, the spin cycle will continue at lower speeds.
Thanks to the asynchronous motor, the required spin speed can be reached almost instantly. The machine, using special rocking movements of the drum, optimally distributes the laundry, then instantly picks up speed, and then it is held in the desired position by centrifugal force.
Yongbin Lim, Daewoo Electronics: “The intelligent direct drive dramatically reduces vibration and noise from drum rotation even when loading a large amount of laundry into the washing machine.”
Daewoo Electronics washing machines use a special “Intelligent Direct Drive Motor”, which provides direct drive to the drum. In this case, additional links are eliminated - a belt and a pulley, which ensure the transmission of torque from the motor to the drum shaft, that is, the belt and pulley are simply absent from the design.
Thus, the torque from the motor is transmitted directly to the drum shaft. With such kinematics, unwanted vibration and noise are minimized.
And, of course, our washing machines are equipped with imbalance sensors: when imbalance occurs, often due to mixed-up laundry, the machine begins to spin the drum in different directions, trying to distribute the laundry evenly across the drum. This function saves customers from unwanted consequences associated with breakdowns of the main components and assemblies of the washing machine.
Possible causes of imbalance
Most often, an imbalance appears due to exceeding the maximum permitted load and crumpled laundry. As a rule, this problem is easily solved by opening the hatch, pulling out the excess, or evenly moving the clothes along the walls of the drum. It is more difficult if the cause of the imbalance of the tank is an installation error or breakdown.
Cracks in a concrete counterweight can be easily repaired by covering the holes with cement mortar and PVA glue.
It’s not for nothing that imbalance control is called the “self-preservation instinct” of a washing machine. Only by being able to sense the approaching danger, the machine will be able to stop operation in a timely manner, minimize risks and last at least 5-7 years.

Simple reasons
There are many reasons why such a defect may occur. Any mechanism tends to wear out, and the parts included in the design of washing machines are also no stranger to this.
The human factor also plays a significant role: the owner’s attitude towards the equipment, how carefully he operates and cares for it. Quite often the causes of noise are very banal.
Incorrect installation
If even a new machine is installed incorrectly, owners will quickly realize that it is not working properly. This will be especially pronounced in the mode with the maximum number of drum revolutions.
Before you panic, you should check whether the washer is installed correctly. To do this, you can take a level and determine how level it is. If there is a skew in one direction, it must be eliminated by moving the machine to a more level surface.
Important! Many manufacturers of washing machines have already come up with a solution to this problem: the washing machines they produce have legs at the bottom that are adjustable in height, adjusting to uneven surfaces.
With the help of these legs, there will be no problems installing the washing machine on an uneven surface.

What to do if the washing machine makes noise when spinning clothes?
The washing machine has long taken its rightful place among essential household appliances. Like any other technical device, the machine is subject to various types of malfunctions and breakdowns. Due to the popularity of household appliances, the experimental base for self-repair continues to increase.
Why is the balance disrupted?
Typically, drum imbalance occurs when the automatic control system enters the spin phase. Linen bunched together leads to imbalance, and the equipment is subject to severe shaking. The imbalance problem occurs due to the following reasons:
In many modern models, the appearance of an imbalance can be recognized by displaying an error with the corresponding code. To prevent problems from occurring, do not load the machine more than specified in the instructions. Filling - up to 70 percent of the volume. If things are bulky, when wet they will become heavy and cause overload - this must be taken into account when loading the tank. It is advisable to wash items of different sizes together - this will distribute the load evenly.
Choosing an installation location
You can avoid discomfort, accelerated wear and related breakdowns if the machine is initially installed correctly. After purchase, all safety and fastening elements used during transportation must be removed. Next, you need to free the moving parts - rotating components are often clamped with bolts during transportation. Turning on without removing the bolted connection will inevitably lead to failure.
The optimal option for placing the unit is on a special pedestal, followed by leveling. If the position needs to be adjusted, a special design of the legs is provided for this - they are unscrewed to select the optimal height at each corner of the device. The appearance of even minor distortions will lead to vibration and increased noise.
Causes of strong vibration during the spin stage
If the machine vibrates too much, this factor clearly indicates the appearance of an imbalance. Our specialists will help you find out what exactly the problem is. Most often in our practice we encounter malfunctions of the following components:
Only specialists will be able to reliably determine the cause of the malfunction. The approach to servicing new and used machines has fundamental differences. In the first case, the most likely causes are improper transportation and installation; in the second, wear and tear of key functional units.
Balancing a washing machine drum - how to do it yourself
If your washing machine jumps and hums a lot during the spin process, then the balance of the drum is likely to be imbalanced. This type of malfunction must be corrected as quickly as possible. And the point here is not only the noise that the machine creates. When the drum is unbalanced, parts of the device wear out. In this article you will learn how to balance a machine drum.
For what reasons does the imbalance occur?
The imbalance occurs during the spin process. The laundry in the drum of the machine clumps into a lump, resulting in an imbalance. At the same time, the washing equipment begins to shake violently.
The following are the main reasons why imbalance may occur:
On some modern models of washing equipment, when an imbalance occurs, a corresponding error code appears on the display.
Where to look for a breakdown
As you can see, the reasons can be completely different. To correctly identify at least one of them, you need to approach this issue with all seriousness. Where to look for the cause of a machine malfunction , what to do when it starts jumping around a lot while the spin function is running? First of all, the simplest causes should be excluded.
If the problem is imbalance:
- You have exceeded the permissible drum loading volume - things should not fill the drum more than two-thirds;
- The permissible weight of the laundry has been exceeded;
- When wrung out, the laundry bunched up and small items of clothing got into the duvet cover.
If you purchased the equipment recently , and this is one of the first washes, the occurrence of strong vibration during the spin process indicates that the transport bolts, which are installed for safe transportation, have not been removed. Typically, four bolts are attached.
Another of the simplest reasons why a washing machine jumps during the spin cycle is violations in installation technology . While the equipment is turned on, try to shake it. If it moves at the same time, it means it was installed unstable. This fact provokes strong shaking of the machine. Also, to clarify the reason, use a level to clarify the distance errors when installing the machine.
To check the space between the drum and the tank for objects stuck there, shine a flashlight inside the drum. Rotate it, changing position; if there is a stuck object, you will easily find .
Having made an initial inspection to identify the reason why the washing machine jumps and moves during the spin cycle, and having not identified it, proceed to the search for more serious damage. If the operation of the flavors or the springs inside is disrupted, then along with the shaking you will hear the sound of the drum hitting the body of the machine. The same sound is caused by a weakened counterweight. If the reason is a worn bearing, then in this case you will hear a grinding sound of parts rubbing against each other.
How to fix the problem yourself?
It should be noted that modern models of washing equipment from LG, Samsung, Bosch or Ardo are equipped with automatic drum balancing. The name of this function is “Imbalance Control”.
If the balance is imbalanced, this system will not allow the washing machine to start spinning the laundry until the problem is corrected. The drum of the machine will spin in different directions with deceleration and acceleration.
If the user has set the spin of the laundry at the highest speed, and the imbalance has not been corrected, the washing machine will greatly reduce the rotation speed of the drum during spinning. In this way, the machine will prevent damage to parts. Also, the spinning of the laundry may stop completely. In both cases, the user will remove almost wet items from the drum.
Automatic load balancing
Automatic balancing is relevant when the user decides to wash a lot of clothes, resulting in an imbalance in the drum. That is, things accumulate in one area, and the mechanism is overloaded. This is fraught with rapid wear of the supporting elements, the engine and, in particular, the bearings. The owner himself cannot identify such a problem by eye, but with a modern Smeg washing machine this is not required. Automatic balancing starts if a special sensor is triggered. The washer stops the cycle and begins to slowly rotate the drum from side to side so that the laundry is distributed evenly.
Why does the washing machine stop while washing?
Overload or imbalance of the drum, blockage The most common reason for stopping the washing machine
machine during washing is incorrect loading of laundry into the drum.
... The amount of laundry placed by weight is greater than the maximum drum load of this type of washing
machine. Items are not placed in the drum correctly.
