Quick answer
tC8 is a temperature sensor error on Samsung heat-pump dryers.
Model compatibility: Samsung reuses codes across series and model years, so tC8 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Temperature sensor error.
Samsung heat-pump dryers can display tC8 to report a temperature sensor error. The Russian Samsung table gives the reason as incorrect operation of that sensor.
Your next step
No checks for the owner are listed with tC8. Request service and keep the dryer unplugged until then if you prefer.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
