Severe vibration and movement of the body of a Samsung washing machine during a high-speed spin often indicates that the shipping bolts were not removed after installation. If these retaining elements are left in place, the drum is rigidly attached to the rear wall of the tank, making normal shock absorption impossible and resulting in extreme vibrations of the entire structure. Ignoring this stage of preparing equipment for work is the most common mistake that can damage shock absorbers and damage the tank after just a few wash cycles.
The second most common cause of unstable behavior of the unit is the uneven distribution of laundry inside the drum or installation of the device on an uneven floor. When wet laundry bunches up on one side, a mass imbalance occurs, which the control system cannot always compensate for by changing the rotation speed. In such cases Samsung may try to spin the drum, but the physical distortion causes the body to make chaotic movements, hitting furniture or walls.
A critical factor is also the wear of suspension components, such as springs or dampers, which lose their properties over time. If your car is several years old and it suddenly starts “jumping” around the bathroom, the problem most likely lies in the mechanical wear of the elements that dampen vibrations. In this material we will analyze in detail all possible causes, from simple settings to complex repairs, so that you can diagnose the problem yourself.
Checking transport bolts and installation stability
The first step in diagnosis should always be to check for the presence of transportation bolts, since they are the ones blocking the movement of the drum. These metal rods are inserted through holes in the rear of the housing and hold the tank stationary for safe transport. If you see that the Samsung washing machine jumps during the spin cycle, immediately check the back wall: if the bolts are in place, they need to be unscrewed urgently using the wrench included in the kit.
⚠️ Attention: Operating the machine with the transport bolts installed leads to the destruction of the tank and bearing assembly in the shortest possible time.
Besides the bolts, proper installation on the floor is critical. The legs of the device must be unscrewed so that the body stands solidly and does not wobble when pressed on the diagonal corners. To adjust the height, use an adjustable wrench to tighten the supports until they make full contact with the surface, then be sure to tighten the locknuts. If the floor is slippery (for example, ceramic tiles), it is recommended to use a special anti-vibration mat or pads under the feet to increase traction.
- 🔧 Check the four shipping bolts on the back panel and remove them if installed.
- 📏 Make sure that all four legs fit tightly to the floor and the machine does not rock when pushed slightly.
- 🧱 Assess the strength of the flooring; weak wood floors may resonate with machine vibration.
- 🧺 Use a level to check that the housing is installed horizontally in two planes.
Linen imbalance and loading errors
A common reason why a Samsung washing machine vibrates a lot is a simple imbalance of the laundry inside the drum. Modern models are equipped with sensors that try to correct the rotation, but if the mass is distributed extremely unevenly, physics takes its toll. For example, washing one heavy terry towel or down jacket without other items often causes the wet fabric to stick to one side of the drum, creating a powerful centrifugal force.
The control system may try to fluff the laundry several times by turning the drum in different directions, but if this does not help, it either reduces the spin speed or stops with an error. The user should avoid washing single heavy items and try to fill the drum evenly, without exceeding or underestimating the recommended dry load weight. It is also important to check pockets before washing, as heavy metal objects can damage the drum and create additional noise.
Wash large items, such as blankets or jackets, in special bags or together with other items to ensure that the weight is evenly distributed throughout.
If you notice that the problem only occurs with certain types of fabrics, try changing the wash program to a more delicate one with a lower spin speed. Sometimes manually distributing the laundry before starting the spin cycle helps, if the model allows you to pause the process. Regularly cleaning the filter and checking the pipes will also help to avoid situations where residual water affects the weight and balance.
Wear of shock absorbers and suspension springs
When the washing machine jumps during the spin cycle and simple check methods do not help, you should pay attention to the condition of the shock-absorbing elements. Shock absorbers (dampers) dampen vibrations of the tank during rotation, and springs keep it suspended. Over time, the lubricant in the dampers dries out, and the rod begins to move with play, which is why the vibration damping stops and the rotational energy is transferred to the body.
Diagnostics of shock absorbers can be carried out manually: with the machine disconnected from the network, press on the top of the tank through the hatch or removed cover. If the tank moves easily, by leaps and bounds, and does not return smoothly to its original position, but begins to sway, it means dampers require replacement. The springs are checked for stretching or breakage; if they are stretched, the tank warps, which also leads to beating.
How to replace shock absorbers
Remove the top and rear covers of the machine. Disconnect the lower shock absorber mountings from the base. The top mounts are usually located on the tank and may require careful removal. Install new parts, observing the orientation, and check the movement of the tank.
Replacing these elements requires partial disassembly of the case, but is often the only way to return the equipment to smooth operation. It is important to buy spare parts that match your specific model Samsung, since the length and stiffness of shock absorbers may vary. Ignoring this problem will cause vibration to begin to destroy other components, including bearings and electrical contacts.
Problems with counterweights and tank
Counterweights are heavy concrete or cast iron blocks mounted on top and sometimes in front of the tub to compensate for the weight of the laundry and the motor. If your Samsung washing machine shakes during the spin cycle, the reason may be that the fastening bolts holding these weights are loose. During intense vibration, the bolts can spontaneously unscrew, which leads to play between the counterweight and the tank, causing rumble and a shift in the center of gravity.
An even more serious problem is a crack in the tank itself or its halves. If the plastic tank bursts, it loses its tightness and rigidity, which immediately affects the balancing. Water may leak, and vibration increases many times over. In such cases, it is often necessary to replace the tank assembly, since repairing plastic cracks under constant dynamic load conditions rarely produces a long-term effect.
☑️ Diagnostics of counterweights
| element | Problem Symptom | Test method | Solution |
|---|---|---|---|
| Counterweight | Rumble, the sound of metal hitting concrete | Visual inspection of bolt tightness | Tightening or replacing fasteners |
| Buck | Water leak, strong shaking | Inspection for chips and cracks | Replacing the tank assembly |
| Springs | Tank distortion, sagging | Comparison of coil lengths | Replacing a set of springs |
| Shock absorbers | Rocking, no resistance | Pressing the tank with your hand | Replacing dampers |
Bearing failure
A humming noise that increases with increasing rotation speed and strong vibration often indicate bearing wear. When bearing unit exhausts its service life, the drum shaft begins to play, which leads to beating at high speeds. This is one of the most difficult faults, requiring complete disassembly of the machine and pressing in new bearings or replacing the tank assembly if it is not dismountable.
Bearing wear can be determined by a characteristic sound, reminiscent of an airplane rumble, which intensifies during spinning. If, when rocking the drum by hand (with the belt removed), you feel a clear knock or free movement of the shaft, then the problem is in the rotation bearings. Operating the machine in this condition is dangerous, since bearing failure can lead to engine seizure or oil seal damage and water leakage.
Replacing bearings is a labor-intensive process that requires special tools and skills; it is often more economically feasible to replace the tank and drum assembly.
Electronics and engine malfunctions
In rare cases, the reason that a Samsung washing machine vibrates is not due to the mechanics, but to the electronics. A faulty Hall sensor or problems with the control module may cause the rotation speed to be read incorrectly. As a result, the motor receives incorrect commands and spins the drum jerkily or exceeding permissible speeds at stages where this is not provided for by the program.
It is also worth checking the condition of the motor brushes if it is a commutator motor. Worn brushes cause sparking and unstable operation of the motor, which can affect the smoothness of rotation. However, most often electronic errors are accompanied by a fault code displayed on the display, which greatly simplifies diagnosis. If the machine shows an error code related to the engine or speed, check the sensor circuit first.
Frequently Asked Questions
Why does the new Samsung washing machine jump when you first turn it on?
Most likely, the shipping bolts from the rear panel were not removed. This is a mandatory procedure before the first start. Also check that the protective tape has been removed and that the legs are level.
Can the machine be used if it vibrates a little?
Not recommended. Even slight vibration over time destroys the fastenings, leading to cracks in the tank and failure of the bearings. The cause must be found and eliminated.
How can you tell if your shock absorbers are worn out?
Press the tank from top to bottom. If it moves easily and does not return to its original position smoothly, but continues to oscillate, the shock absorbers have lost their properties and require replacement.
Does the floor in the bathroom affect the performance of the washing machine?
Yes, wood floors or hollow tiles can resonate with vibration. Using an anti-vibration mat or footrests often solves the problem.
What to do if the car moves a few centimeters?
The displacement indicates a strong imbalance or lack of adhesion of the legs to the floor. Check the load of laundry, the tightness of the locknuts on the legs and the condition of the floor.
