Samsung washer error code · Ub / UE

Unbalanced or not spinning

This is a washing-machine fault guide. The code above comes from the washer display; it is not the model number. Separate a load problem from leveling or a likely internal fault.

Stop immediately for smoke, burning odor, sparking, violent movement, or water near electrical parts. Do not touch a wet plug.

Step 1 · Verify the appliance

Enter the complete model number

A brand and error code are not enough. Unsupported or mismatched models stop here.

Step 3 · Cost decision

Repair, claim warranty, or replace?

This transparent heuristic starts only after safe checks and a real repair estimate. It never identifies a failed part.

Washer age (years)Written repair estimate ($)Comparable replacement, delivered ($)Warranty covers this failure?Same failure happened before?

Published rule: warranty coverage wins first. Otherwise the tool compares repair cost with delivered replacement cost, then uses age and repeat failure only as tie-breakers. It does not include energy savings, financing, sentimental value, or local disposal incentives.

Parts note

We may later earn a commission from clearly labeled links. For now, no part is recommended from an error code alone. Match the full model number and confirm the failed component first.
