What Underlined u
actually means.
The underlined u means the zone does not detect suitable cookware: nothing is there, the pan is not magnetic, or it is too small. After 30 seconds the zone turns off.

What to do when Underlined u shows on the cooktopKind of codeMode, not a failure
A state the cooktop was put in, or one it picked deliberately — a child lock, a demo mode that lights the keys but heats nothing, a residual-heat letter over a zone that is still warm, a prompt that no pan has been found. Nothing has broken and no part is called for.
Usually leads toNo repair
Use a magnetic pan that matches the zone size.

Printed in the information code tables of Samsung's manuals for the NZ30A3060UK and NZ30K7880US induction cooktops (both carry a U.S.A. warranty page). Samsung's support article on cooktop codes names it the pan detection error.
Before you book,
in this order.
Each step comes from Samsung's own guidance for Underlined u on its cooktops. Follow it to the end: the last card says whether this is a visit.
Use a magnetic pan that matches the zone size.
Hold a magnet to the pan base; if it does not stick, that pan will not work on this induction zone.
If the symbol appears with a known-good pan, book a visit.
Cleared?
The cooktop came right without a new part. If the same message returns while a zone or burner is on, or the top shuts itself down again mid-meal, treat it as a fresh problem and book it.
What not to do
The underlined u is not a failed coil. It also does not mean the glass is damaged; the zone simply found no cookware it can heat.
What you may
