Samsung Washing Machine: error code UB, not spinning properly
What is this symptom?
Is your Samsung washing machine displaying error code UB and failing to spin properly? This common issue typically arises from an unbalanced load, causing the machine to halt during the spin cycle. Understanding the causes and solutions can help you get your washer back to normal operation quickly.
Important Tips for Samsung Models
- Samsung official support identifies UB error as unbalanced load (same as UE) and recommends correct placement, load distribution, and leveling.
Possible Causes
Unbalanced laundry load
How to Identify: Error UB appears when clothes are unevenly distributed in the drum, often after heavy items clump on one side; washer vibrates or stops.
Part: Drum load distribution
Worn or damaged suspension system (rods/shocks/springs)
How to Identify: Persistent UB after correct loading/leveling, machine shakes loudly, drum sagging.
Part: Suspension rods/shock absorbers/springs
Faulty Hall sensor or wiring
How to Identify: UB persists without actual imbalance; sensor diagnostics may show errors.
Part: Hall sensor/drum speed sensor
Drive belt or internal mechanical wear
How to Identify: Continuous UB with unusual noises; drum doesn’t spin freely even with balanced load.
Part: Drive belt/bearings
DIY Solutions
Redistribute laundry load
- Pause washer and open door.
- Rearrange clothes by spreading heavier and lighter items evenly around the drum.
- Remove some items if overloaded or add small items if underloaded.
- Restart spin cycle.
Level the washing machine
- Unplug washer.
- Use level tool on top of washer to check balance.
- Adjust each leveling foot by turning to raise/lower until machine is stable.
- Ensure all four feet touch floor and tighten nuts.

Reset washer power (power cycle)
- Turn off washer and unplug from power.
- Wait 1–5 minutes.
- Reconnect power and run a test cycle.
