Seeing **tC1** on a Samsung washing machine narrows the problem to **temperature sensor error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **tC1**. Search normalization stores it as **TC1** while preserving the characters a homeowner actually sees.

Temperature sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so TC1 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. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. For tC1, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.
Persistent temperature-sensor codes usually require resistance/connection checks at the sensor, harness, and control—work best done with the model-specific service procedure. In a service visit for tC1, model-specific testing should follow the temperature sensor error circuit rather than treating the code as proof of one failed part.

Temperature sensor error.
A single documented power reset can help after an external condition or power event is corrected. If **tC1** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Do not keep operating the appliance through a hazardous symptom just to see whether **tC1** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
Treat **tC1** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
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 tC1** separate from same-looking codes used by other Samsung appliance families.
