Samsung Washer error code Ub

Also shown as: UE

What it means

Spinning does not work - the load is unbalanced.

Likely causes

Laundry is bunched up or spread unevenly in the drum
The washing machine is not on a flat, stable surface
The load is a single item or very small

Safety first: switch the appliance off and unplug it (or turn it off at the circuit breaker) before you check anything. If water is involved, close the water supply valve too. Never open panels or touch internal wiring. Anything that involves gas lines, refrigerant or sealed systems, or mains-voltage wiring is a job for a professional - not a home fix.

Safe first checks

Pause the cycle and spread the laundry out evenly
Add one or two towels if you are washing a single heavy item
Make sure the washer sits on a flat, stable surface and does not rock

When to call a pro

If the code appears even with an empty drum or a balanced load, ask a service center to check it.

Repair or replace?

Try the safe checks first - many codes clear with a clean filter, a straight hose or a balanced load, and those cost nothing. If the code comes back, a service call typically costs $50-$150 for the visit and diagnosis (Angi puts an average service call at $50-$100; Sears lists a $90-$150 diagnostic fee). Get the full repair quote before you decide. If the machine is old and the quote is a large part of the price of a new one, replacing usually makes more sense than repairing.
