The situation when a washing machine begins to vibrate excessively or, as people say, “walk” on the floor during a spin cycle, is familiar to many owners of household appliances. This is not just an annoying noise that interferes with rest, but also a serious signal that balancing system drum is broken. If you ignore the first signs of displacement, you can end up with more expensive repairs, including tank destruction or engine failure.
Most often, the problem lies in improper installation or natural wear of parts responsible for damping vibrations. However, before calling a specialist, it is worth conducting an independent diagnosis, since in many cases the cause is eliminated in a few minutes without special tools. It is important to understand that centrifugal force, which occurs when the drum rotates at high speeds, requires ideal stability of the entire structure.
In this article we will analyze in detail all possible causes, from basic installation errors to complex mechanical breakdowns. You will learn to distinguish between normal vibration and dangerous beating, and also understand when you can handle it yourself and when it is better not to take risks. The correct reaction to the symptom of a “walking” machine will extend the life of your unit and will keep the flooring intact.
Checking the correct installation and transit bolts
The most common but common cause of extreme vibration is forgotten transport bolts. These are special fasteners that secure the tank inside the housing during transportation, preventing it from damage. If they are not unscrewed before the first start, the machine will not just jump, but literally jump around the bathroom with a deafening roar.
Check the back of the unit: there should be 3 to 4 bolts (sometimes with plastic washers) that hold the shock absorber in a compressed state. They must be completely unscrewed and the holes closed with plastic plugs included in the kit. Operating the machine with the transport bolts in place, even during one spin cycle, can cause permanent damage to the bearing assembly.
The second important aspect of installation is the horizontality of the housing. If the legs are not adjusted correctly, the center of gravity shifts, and when accelerating, the car begins to tilt to one side. Use a building level to check the position of the equipment in all axes. The height of the legs is adjusted by rotating them: by twisting or unscrewing the supports, achieve perfect contact with the floor.
It is also worth considering the type of flooring. On slippery tiles or laminate floors, even a perfectly adjusted machine can move due to inertia. In such cases, it is recommended to use a special anti-vibration mat or pads under the legs, which will increase friction and absorb some of the vibrations.
⚠️ Attention: Never leave removed shipping bolts just lying next to the machine “just in case.” They are easy to lose when moving, and without them, repeated transportation without fixing the tank is impossible. It is better to immediately put them in the box with the documentation.
Diagnostics of wear of shock absorbers and suspension springs
If everything is fine with the installation, but the car still jumps, most likely the problem lies in shock absorbers. These parts work on the principle of car racks: they dampen the vibrations of the tank during the spin cycle. Over time, the oil inside them leaks out, or the seals wear out, causing them to stop performing their function.
To check shock absorbers, it is not always necessary to completely disassemble the car. Open the hatch and press the top of the drum with your hand, simulating a load, and then quickly release it. If the tank swung and immediately stopped, the depreciation is normal. If it continues to shake like a pendulum, it means the shock absorbers are “dead” and require replacement.
The suspension springs that hold the tank on top also play an important role. They must be intact and have the same length when at rest. If one of the springs is stretched or bursts, the tank warps, causing strong beating when rotating. Replacing these elements requires removing the top cover and partially disassembling the housing.
Often, along with shock absorbers, they also change damper pads, if they are provided for by the design of your model. Ignoring the wear of these parts causes all the vibration to be transferred to the body and floor, and also accelerates the destruction of other components, such as bearings.
How to replace shock absorbers yourself?
Replacing shock absorbers usually requires removing the rear or front wall of the housing (depending on the model). Shock absorber bolts may be tight, use WD-40. It is important to buy original spare parts or high-quality analogues, since cheap shock absorbers can leak after a month of active washing.
Problems with counterweights: concrete or metal?
Counterweights are heavy blocks attached to the front and back of the tub that balance the weight of the wet laundry. They can be made of cast iron or concrete. If the washing machine vibrates a lot, check that these elements are securely fastened. Loose bolts allow the counterweight to “walk” with the tank, creating dangerous resonance.
Particular attention should be paid to concrete counterweights. Over time, concrete may begin to crumble or crack, especially if the machine has been subjected to overload or shock during transportation. A crack in the counterweight changes its weight and geometry, making balancing impossible. Visual inspection and tapping will help identify hidden defects.
In some cases, owners are faced with a problem when the counterweight mounting bolts spontaneously unscrew due to constant vibration. This can cause a heavy block to simply fall off and go through the bottom of the car or damage the floor. Regular tightening of fasteners (once a year) will help avoid this situation.
If you find a crack in a concrete block, repair it using epoxy resin, but this is a temporary solution. It is safer to replace a damaged element with a new one to guarantee stable operation centrifugation systems.

Wear of the bearing unit and drum shaft
One of the biggest causes of vibration is bearing wear. When the bearing unit reaches the end of its service life, play appears in it, and the shaft begins to rotate not strictly along the axis, but with runout. This leads to the fact that the drum begins to “chatter” from side to side, especially at high speeds.
The main symptom of worn bearings is a characteristic hum or roar when the drum rotates, which intensifies during spin cycles. If you hear this sound and see that the machine is shaking on the floor, most likely the bearings have already been destroyed. Operation in this condition is dangerous: the shaft may rust and jam, or even break.
Replacing bearings is a complex repair that requires complete disassembly of the tank. In modern models, tanks are often sealed, which makes replacing bearings economically impractical - you have to replace the entire tank. Therefore, it is so important to monitor the condition of the seal, which protects the bearing from water.
To extend the life of bearings, try not to overload the machine and use high-quality detergents. Excess foam and aggressive chemicals destroy the seal, water enters the bearing, washes out the lubricant and causes corrosion. Tightness node is the key to quiet operation.
| Symptom | Probable Cause | Difficulty of repair | Urgency |
|---|---|---|---|
| Hum and vibration | Bearing wear | High | High |
| Jumping during push-ups | Shock absorbers | Average | Average |
| Offset by floor | Floor/Legs | Low | Low |
| Knock and clang | Counterweights | Low | Average |
Violation of the rules for loading laundry
Sometimes the reason for a “dancing” machine is trivial - incorrect loading. If you wash one heavy item (like a wet blanket or bath mat) without other items to balance it out, the laundry will clump together. During spinning, this lump shifts the center of gravity, and the machine cannot evenly distribute the load.
Modern models automatic washing machines equipped with imbalance sensors. If the machine senses a misalignment, it may slow down, try to fluff the laundry, or stop the program altogether. However, older models or machines without this feature will try to spin the laundry at all costs, which will result in strong shocks.
To avoid this, try to load things evenly throughout the entire volume of the drum. Don't fill the machine to capacity, but don't wash too few things either. The optimal load is when there is a palm-sized space between the laundry and the wall of the drum.
It is also important to sort items by fabric type. It is better to wash heavy jeans and light T-shirts separately or mix them thoroughly. Mixing fluffy fabrics with smooth ones can lead to the laundry forming a ball that is difficult to fluff up even with the “light ironing” function.
If the machine stops due to imbalance, do not immediately try to start the spin cycle again. Open the hatch, straighten the laundry manually, add a couple of items for weight (if there are not enough) or remove the excess, and only then start the cycle again.
Rare causes: heating element, motor and electronics
In rare cases, vibration may be caused by the displacement of the heating element (heater). If a thick layer of scale has formed on the heating element, when squeezing, pieces of lime may fall off and get between the tank and the drum. This causes a characteristic knocking and beating sound. In addition, if the heating element itself is poorly secured, it can dangle and create noise.
Engine problems can also cause vibration. Worn brushes in brushed motors or faulty motor bearings cause uneven rotation. In machines with Direct Drive, wear of the motor bearings is also possible, although it happens less frequently.
In rare cases, the electronic control module may fail, sending incorrect commands to the engine, resulting in jerking and chaotic rotation. However, this is usually accompanied by other symptoms: errors on the display, spontaneous stops or the inability to select a program.
If you have checked all the mechanical parts and the problem persists, it may be due to a hidden defect or a combination of several factors. In such cases, it is better to turn to professional diagnostics so as not to guess and not waste money on unnecessary spare parts.
⚠️ Attention: Before any disassembly of the machine, even to check the heating element or shock absorbers, be sure to disconnect the device from the power supply! Water and electricity are a deadly combination.
FAQ: Frequently asked questions
Why does the new washing machine vibrate more than the old one?
Modern machines often have a lighter body and an efficient but harsh spin cycle. If the floor is uneven or slippery, they will feel less stable. It is also possible that you simply forgot to unscrew the shipping bolts.
Can I use the washing machine if it bounces a little?
Short-term - possible, but not recommended. Constant vibration destroys connections, leading to leaks and bearing failure. It is better to eliminate the cause immediately so as not to pay for major repairs.
Does an anti-vibration mat help with strong jumps?
The mat helps with minor vibration and slipping on smooth floors. If the car is bouncing due to broken shock absorbers or forgotten bolts, a mat will not help the situation and may even make the instability worse.
How often should shock absorbers be replaced?
The service life of shock absorbers depends on the intensity of washing. On average, they walk for 5-7 years. If you wash large volumes every day, the resource may be exhausted faster, after 3-4 years.
90% of problems with a “walking” washing machine are solved by checking the transport bolts, adjusting the legs or replacing shock absorbers. Don’t rush to throw away your equipment or buy a new one; repairs are often inexpensive.
