Quick answer
3CP signals an electronic control issue. Restart the cycle first; contact Samsung if it stays on the display.
Model compatibility: Samsung reuses codes across series and model years, so 3CP may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
