# Samsung cooktop error code Underlined u

### 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. It is the only code Samsung publishes for a cooking surface, and nine times in ten it is a pan rather than a repair.

### 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](/services/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](tel:+13055061256) and describe what the panel is doing before booking anything.
