What Underlined u
actually means.
The underlined u is Samsung's pan detection signal on induction models. Something about the pan, its size, its metal or where it sits, keeps the zone from heating, and after a minute without a fix the zone gives up and switches off.

What to do when Underlined u shows on the stoveKind of codeStovetop elements
A burner on an electric or induction stovetop did not heat the way the knob or key asked, heated with nothing set, or ran hotter than the setting. The pan, a lock left on and the switch behind the knob are checked before the element under the glass, its limiter or an induction board is changed. If a burner keeps heating after it has been switched off, turn the stove's breaker off before anything else.

Before you book,
in this order.
Each step comes from Samsung's own guidance for Underlined u on its stoves. Follow it to the end: the last card says whether this is a visit.
Slide the pan so it sits in the middle of the printed circle.
Check the pan with a magnet: if the magnet does not cling to the base, it will not work on induction.
Pick a pan whose base suits the size of the zone and try again.
Book a visit if a pan that works on the other zones still shows the underlined u.
What not to do
The underlined u is not a broken zone in most cases. It is the stove telling you about the pan.
