For the Samsung Washer families covered by the source set, **UC** means **power / voltage error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **UC**. Search normalization stores it as **UC** while preserving the characters a homeowner actually sees.

Power / voltage error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so UC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Important safety warning. When working around a washing machine that shows UC, keep the checks external and non-invasive. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.
If the owner-accessible checks do not clear UC, Persistent power/voltage codes need the household supply and appliance power/control circuits checked safely before parts are replaced. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Power / voltage error.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **UC** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **UC** should not be ignored if performance is deteriorating or the display keeps returning.
No. **UC** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Washer UC** separate from same-looking codes used by other Samsung appliance families.
