What UP reports
The cooktop is running outside its normal voltage, which Samsung puts at 220-240 V. That is the meaning of UP. It comes from Samsung’s Australian cooktop listing and refers to Australian models.
Samsung’s instruction
Check the power environment at home.
The listing goes no further, so anything past that check is for a technician.
Underlined u: a cookware problem on induction cooktops.
