What we can confirm
Code Underlined u, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
Underlined u
Drawn as a u with a line under it — the maker's own picture of a pan bottom sitting above a surface — and it appears only on induction. It means the cookware is the wrong size, the wrong material or in the wrong place on the element, and the zone will not heat. Left uncorrected the element switches itself off after a minute. It is the only code Samsung publishes for a cooking surface, and nine times in ten it is a pan rather than a repair.

What it narrows down to
the cookware, not the appliance
Diagnostic
From $95, credited to the repair
On the same appliance
What else belongs to the cooktops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
the door is not being seen as closed
the appliance is not properly connected to its supply
the code is real, and Samsung publishes no procedure for it

What Underlined u means on this make
Drawn as a u with a line under it — the maker's own picture of a pan bottom sitting above a surface — and it appears only on induction. It means the cookware is the wrong size, the wrong material or in the wrong place on the element, and the zone will not heat. Left uncorrected the element switches itself off after a minute.

The other ways Samsung prints this one
Underlined u · u
Samsung publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with. They mean the same thing and they are one page here, so whichever of them you searched for, this is the right page.
Where this appears, and why not to clear it
On the appliance's own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.
What to do about it
- Check the pan is magnetic — a fridge magnet that sticks firmly to its base will do.
- Center it on the element. A pan smaller than the ring often will not be seen at all.
- Try the same pan on a different zone; a pan that works on the large ring and not the small one is a size problem.
- If good cookware, properly centered, is refused on every zone, then the coil or its sensing needs looking at.
Where this goes next
The job this usually becomes is induction cooktop repair, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 506-1256 and describe what the panel is doing before booking anything.
