Dealing with a Samsung washing machine not spinning but making noise can be a frustrating experience for any homeowner, interrupting your daily routine. This specific problem often indicates a mechanical failure or an obstruction that prevents the drum from rotating while the motor or pump continues to operate. Diagnosing the root cause requires checking several key components, from the drive system to the drainage assembly.
Below is a detailed technical guide to help you identify and resolve the issue, focusing on the specific parts that most commonly fail.

Why Is Your Samsung Washing Machine Not Spinning but Making Noise?
When your washer hums, grinds, or bangs without spinning the clothes dry, it usually points to one of two categories: a drive system failure or a drainage issue. The machine’s safety protocols may stop the spin cycle to prevent damage, but the noise suggests a component is struggling to work.
1. Drive Belt
In non-direct drive models, the drive belt connects the motor to the drum. Over time, this rubber belt can stretch, fray, or snap.
- Symptoms: You may hear the motor running (a humming sound), but the drum remains stationary. A squealing noise often indicates a loose belt slipping on the pulley.
- Solution: Remove the back panel to inspect the belt. If it is worn, cracked, or has fallen off, it must be replaced to restore the spin function.
2. Drain Pump
A washing machine will not enter the spin cycle if it cannot drain water first. The drain pump is responsible for expelling water, and it is a common source of noise.
- Symptoms: A loud grinding or buzzing noise coming from the bottom of the machine suggests the pump is jammed with debris (like coins or buttons) or the impeller is broken.
- Solution: Check the debris filter (usually on the front bottom right). Clean it out thoroughly. If the noise persists and the washer won’t drain or spin, the drain pump motor likely needs replacement.
3. Drum Bearings
The drum bearings support the inner tub and allow it to rotate smoothly. When the water seal fails, water enters the bearings, causing them to rust and degrade.
- Symptoms: This is characterized by a “roaring” or “jet engine” sound that gets louder as the spin speed increases. Eventually, the friction can become so great that the drum refuses to spin.
- Solution: This is a complex repair requiring the complete disassembly of the tub. If you confirm the bearings are shot (by lifting the drum rim to check for excessive play), a full bearing and seal replacement is necessary.
4. Motor Carbon Brushes
Older Samsung washing machines with universal motors rely on motor carbon brushes to conduct electricity to the armature.
- Symptoms: As brushes wear down, they lose contact with the motor, leading to a sputtering sound or intermittent power. The motor may hum but lack the torque to spin the heavy wet load.
- Solution: Remove the motor and inspect the brushes. If the carbon is worn down to less than a quarter-inch, install a new set of brushes.
5. Door Lock Assembly
Modern washers have a safety interlock that prevents high-speed spinning if the door is not securely latched.
- Symptoms: You might hear a clicking noise as the door lock assembly attempts to engage but fails. If the main control board does not receive a “locked” signal, it will not send power to the motor for spinning.
- Solution: Inspect the door latch for damage. If the lock mechanism is faulty, the entire assembly should be replaced.
6. Shock Absorbers
Shock absorbers are attached to the base frame and the outer tub to dampen vibrations.
- Symptoms: If these are worn out, the washer will make loud banging or thumping noises. The excessive vibration can trigger the unbalance sensor, causing the machine to stop spinning to protect itself.
- Solution: Press down on the drum; it should not bounce back repeatedly like a basketball. If it does, the shock absorbers are compromised and need replacing.
7. Drive Pulley
The drive pulley is a large wheel attached to the back of the drum (in belt-driven models) or the rotor housing (in direct-drive models).
- Symptoms: If the bolt securing the pulley loosens, it can wobble and grind against the back of the cabinet or the tub. This creates a distinct metal-on-metal noise and prevents effective spinning.
- Solution: Tighten the mounting bolt. If the splines on the pulley are stripped, the pulley itself must be replaced.
8. Suspension Springs
Suspension springs hold the tub assembly from the top of the cabinet.
- Symptoms: A broken suspension spring will cause the tub to lean to one side. This leads to severe banging noises and an immediate shut-off during the spin cycle due to load imbalance.
- Solution: Inspect the springs visually. If one is broken or stretched, replace it immediately to prevent damage to the tub.
9. Stator Assembly
In Samsung Direct Drive (DD) washers, the stator assembly creates the electromagnetic field that drives the rotor.

- Symptoms: Cracked magnets on the rotor or damaged coils on the stator can cause a buzzing or humming noise. The motor may “struggle” to turn the drum, resulting in a spin failure.
- Solution: Use a multimeter to test the stator windings for continuity. Inspect the plastic housing for cracks or damage.
10. Clutch Kit
Top-loading Samsung washers use a clutch kit to engage the tub during the spin cycle.
- Symptoms: If the clutch wears out, the motor will spin the agitator but not the basket, often accompanied by a loud scraping or “ratcheting” noise.
- Solution: A worn clutch assembly cannot simply be repaired; the entire kit usually requires replacement to restore proper spin functionality.
11. Drive Motor
The drive motor is the heart of the washing operation.
- Symptoms: If the motor has internal electrical faults, it may hum loudly (a magnetic hum) without turning. This often happens if a capacitor has failed (on older models) or if the motor windings are burnt.
- Solution: Professional diagnosis is recommended here. If the motor receives power but does not turn and is hot to the touch, it is likely defective.
12. Error Code UE
While not a physical part, the Error Code UE (Unbalanced Error) is critical in diagnosing spin issues.
- Context: This code appears when the washer detects that the load is unevenly distributed. The machine will try to rebalance the load by tumbling and adding water, often making “sloshing” and mechanical clicking noises.
- Solution: If redistributing the laundry doesn’t fix it, this error often points back to the physical support components mentioned above, such as shock absorbers or suspension springs.
Conclusion
A Samsung washing machine not spinning but making noise is rarely a phantom issue; it is almost always a symptom of a specific component failure. By systematically checking the drain pump for blockages, inspecting the drive belt for wear, and listening for the characteristic sounds of bad bearings or shocks, you can isolate the problem.
For complex repairs involving the drum bearings or stator assembly, consulting a professional technician is often the safest route. However, simpler fixes like clearing a drain pump filter or replacing a door lock assembly are well within the reach of a DIY approach.
Frequently Asked Questions
Why does my Samsung washer sound like a jet engine during the spin cycle?
A loud roaring or “jet engine” noise is a classic symptom of failing drum bearings. This usually occurs when the tub’s water seal degrades, allowing water to reach the bearings and cause rust. If you notice this sound getting louder over time or if the inner drum feels loose when you lift it, the bearings likely need to be replaced.
What should I check first if the motor hums but the drum doesn’t move?
The most common culprit for a humming motor without drum movement is a damaged or slipped drive belt. In belt-driven models, the belt connects the motor to the drum pulley; if it snaps or falls off, the motor will spin freely (making a humming or whirring sound) while the drum remains stationary. You should also inspect the motor carbon brushes, as worn brushes can prevent the motor from generating enough power to turn a heavy load.
Can a clogged drain pump prevent my washing machine from spinning?
Yes. Samsung washing machines are programmed to ensure all water is removed before entering a high-speed spin. If the drain pump is clogged with debris like coins, hairpins, or excessive lint, the machine will fail to drain and subsequently refuse to spin. A grinding or buzzing noise coming from the bottom of the unit often indicates that something is stuck in the pump or that the pump impeller is damaged.

What does the “UE” error code mean, and why is my machine banging?
The “UE” code stands for an “Unbalanced Error.” This happens when the machine detects that the load is not distributed evenly, which can cause severe vibration. If the machine makes loud banging or thumping noises even after you redistribute the laundry, your shock absorbers or suspension springs may be worn out or broken, leaving the tub unsupported during high speeds.
