Why Is My Samsung Washing Machine Vibrating So Much?
Check that all four levelling feet are firmly in contact with the floor and adjust them until the machine sits completely stable — a machine that rocks even slightly will vibrate badly at spin speed (takes about 5 minutes).
Fault description
Excessive vibration during a wash or spin cycle is one of the most common complaints from Samsung washing machine owners. You might notice the machine rocking back and forth, banging against the wall, or even walking across the floor. In some cases the noise is loud enough to be heard throughout the house. While it can feel alarming, the cause is usually straightforward.
The spin system — which includes the drum, bearings, suspension rods, and motor — relies on the load being balanced and the machine being level. When either of those conditions isn't met, the forces generated at high spin speeds become very difficult to control. Most cases of excessive vibration can be resolved without any tools or spare parts at all.
Samsung machines across a wide range of models can display this behaviour, and there are no specific error codes associated with vibration alone. If you also see codes such as UE or UB on the display, those indicate an unbalanced load, which is directly related to this symptom.
Causes
- Unbalanced laundry load — A single heavy item like a duvet or jeans can clump to one side of the drum, creating an uneven weight distribution. At spin speeds of 1000 RPM or more, even a small imbalance generates significant vibration.
- Machine not level or feet not adjusted correctly — If one or more of the four adjustable feet are not making firm contact with the floor, the machine will rock during the spin cycle. This is the single most common cause of excessive vibration and is very easy to fix.
- Transit bolts still fitted — Samsung washing machines are shipped with transit bolts at the back that lock the drum in place for transport. If these were never removed before first use, the drum cannot move freely and the machine will vibrate violently. Check the back of the machine for any remaining bolts or plastic spacers.
- Worn or failed suspension rods — The drum is held in place by four suspension rods with damper pads. Over time these wear out and lose their ability to absorb movement, causing the drum to swing excessively during spin. This is more common on machines that are several years old.
- Worn drum bearings — Bearings allow the drum to spin smoothly on its shaft. When they wear out, the drum develops play and wobbles during rotation, producing a loud rumbling or grinding noise alongside the vibration.
- Machine positioned on an uneven or soft floor — Even a perfectly levelled machine will vibrate excessively if it is sitting on a soft wooden floor or a surface that flexes under load. The floor itself amplifies the movement rather than absorbing it.
Step-by-Step Fix
- 1
Check for and remove transit bolts
Look at the back of the machine for three or four large bolts, usually with coloured plastic spacers. These must be removed before the machine is used. Unscrew them by hand or with a spanner and keep them somewhere safe in case you move house. If they are still fitted, this is almost certainly the cause of your problem.
- 2
Redistribute the laundry load
Open the door and manually spread the laundry evenly around the drum. Avoid washing a single heavy item on its own — add a couple of towels to balance the load. Restart the spin cycle and see if the vibration reduces. If your machine shows a UE or UB error code, this step is the direct fix.
- 3
Level the machine using the adjustable feet
Place a spirit level on top of the machine and check it in both directions. Each foot can be turned clockwise to lower it or anticlockwise to raise it — you may need to loosen the lock nut first. Once all four feet are firmly on the floor and the machine is level, tighten the lock nuts to hold the position. Give the machine a firm push at each corner to confirm it does not rock.
- 4
Place an anti-vibration mat under the machine
Rubber anti-vibration mats are inexpensive and sit under all four feet. They are particularly effective on hard floors or slightly uneven surfaces. Make sure the mat is the correct size for your machine and that all feet are sitting on it fully.
- 5
Check the floor surface
If the machine is on a suspended wooden floor, the floor itself may be flexing and amplifying vibration. Try moving the machine to a solid concrete or tiled floor if possible. If moving it is not an option, a thick piece of plywood under the machine can help spread the load and reduce movement.
- 6
Inspect the suspension rods
With the machine unplugged, remove the top panel (usually held by two screws at the back). Look down inside the cabinet at the four suspension rods connecting the outer drum to the cabinet frame. If any rod is detached, bent, or if the damper pad at the top is visibly worn or missing, the rod needs replacing. This is a straightforward part swap that most homeowners can manage.

Listen for bearing noise
Spin the drum by hand with the machine empty and unplugged. A healthy drum spins smoothly and quietly. If you hear a rumbling, grinding, or scraping sound, or if the drum feels rough to turn, the bearings are likely worn. Bearing replacement is a more involved repair — see the section below on when to call a service technician.
When to call a service technician
If you have worked through all the steps above and the machine is still vibrating excessively, or if you can hear a loud rumbling or grinding noise when you spin the drum by hand, the drum bearings are most likely worn out. Bearing replacement requires significant disassembly of the machine and, on many Samsung models, the outer drum must be split apart — this is not a straightforward DIY job.
You should also contact a service technician if you notice the drum visibly dropping or sitting unevenly inside the cabinet, if the machine is leaking water alongside the vibration, or if any electrical burning smell is present. These signs point to more serious structural or mechanical failure that needs professional assessment.
Prevention
The parts most commonly replaced when dealing with excessive vibration on Samsung washing machines are the suspension rods (also called damper rods or shock absorbers), the drum bearings, and anti-vibration feet or foot lock nuts. Suspension rods are a straightforward DIY replacement and are worth inspecting every few years on older machines. Bearings last longer but will eventually wear on any machine that is used heavily.
To keep vibration to a minimum long-term, always load the machine with a balanced mix of items, avoid overloading, and check the levelling feet every six to twelve months as they can work loose over time — especially on hard floors where the machine vibrates more freely.

Frequently Asked Questions
Why does my Samsung washing machine only vibrate on the spin cycle?
Vibration is almost always worst during spin because the drum reaches its highest speed — sometimes over 1200 RPM. At those speeds, even a small imbalance or a slightly loose foot creates a large amount of movement. The wash and rinse cycles run much more slowly, so the same underlying problem may not be noticeable until spin begins.
What does the UE or UB error code mean on a Samsung washing machine?
UE and UB both indicate that the machine has detected an unbalanced load. The machine will usually try to redistribute the laundry by adding water and tumbling slowly before attempting spin again. If it cannot balance the load, it will stop and display the code. Opening the door and spreading the laundry by hand, then restarting, resolves this in most cases.
Is it safe to keep using a washing machine that vibrates a lot?
Mild vibration from an unbalanced load or slightly uneven feet is unlikely to cause immediate damage, but it should be corrected as soon as possible. Persistent heavy vibration puts stress on the suspension rods, bearings, drum spider, and internal hoses, and can shorten the life of the machine significantly. It can also cause the machine to move and damage flooring or nearby cabinetry.
Can overloading cause a Samsung washing machine to vibrate?
Yes. Overloading prevents the laundry from moving freely inside the drum, which makes it almost impossible for the machine to balance the load during spin. As a general rule, the drum should be no more than three-quarters full for a normal mixed load. Heavy items like towels and bedding should be loaded even more loosely.
How do I know if my washing machine suspension rods need replacing?
With the machine unplugged, open the lid or top panel and gently push down on the drum. It should bounce back smoothly and settle quickly. If it bounces several times, feels loose, or drops heavily to one side, one or more suspension rods have lost their damping ability and should be replaced. Visible damage to the rods or worn-out plastic cups at the attachment points are also clear signs.
