Quick answer
tC1, tC2 and tC3 belong to the temperature sensor error group. Samsung's step is a 1 minute reset at the mains.
Model compatibility: Samsung reuses codes across series and model years, so tC1, tC2, tC3 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 UK groups tE, tE1-tE3 and tC1-tC3).
tC1, tC2 and tC3 are temperature sensor errors on a Samsung washer. Samsung’s UK page lists them in one group with tE, tE1, tE2 and tE3, and the instruction is the same for the whole group.
What Samsung says to do
Switch the appliance off at the mains and wait 1 minute. Switch it back on and start a new programme.

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.
