Quick answer
Samsung dishwasher tC1 and tC2: wash completes, drying fails or ends early.
Model compatibility: Samsung reuses codes across series and model years, so tC1, tC2 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
Washing completes but the cycle fails during drying or ends early.
On a Samsung dishwasher, tC1 and tC2 mean washing finishes but the cycle fails during drying or ends early.
