Samsung Washer tC Error Code: Causes and Fixes

Quick answer: On a Samsung Washer, the tC error code means the thermistor (temperature sensor) has detected an abnormal temperature reading. Samsung Washer tC is a temperature control fault — the thermistor is reading a temperature that is outside the expected operating range. This could mean the thermistor itself has failed and is reading incorrectly, or that the actual water temperature is genuinely abnormal (extremely cold or hot inlet water). tC is closely related to the tE thermistor fault code.

Quick Fix for Samsung Washer tC

• Run a power reset: unplug the washer for 5 minutes.
• Check that inlet water temperature is normal — very cold water (near-freezing) can trigger tC on some models.
• Reconnect and retry the cycle.
• If tC persists, the thermistor wiring should be checked for looseness.
• If the thermistor is reading incorrectly (use a multimeter to test resistance at room temperature), replace the thermistor.

Common Causes of Samsung Washer tC

• Faulty thermistor: The NTC thermistor has failed and reads outside the normal resistance range.
• Disconnected thermistor wiring: The thermistor connector has come loose during a cycle.
• Extremely cold inlet water: Water temperature below the minimum sensing range on some models.
• Thermistor wiring short: A wire shorted to the tub or machine frame sends incorrect readings.
• Control board fault: The board cannot process the thermistor signal correctly.
