Error code UP
Appliance Cooktop
Quick answer

UP flags a cooktop outside its normal 220-240 V. Samsung's step is to check the home power environment.

Model compatibility: Samsung can reuse or reformat codes across series and model years, so UP may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
