Almost always this is not a malfunction at all: the two supply hoses are on the wrong taps. It is the single most common installation mistake in a laundry room, it survives for years in houses where nobody runs a cold-only cycle, and it turns up the day somebody does. Samsung says outright that this code does not mean service is needed, and in our experience they are right about it more often than about any other code they publish. ### The other ways Samsung prints this one 4C2 · 4E2 · CE · 14C2 · nF1 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 - Look at the two hoses at the back. Blue to blue, red to red — the connections are marked. - If they are already correct, check whether a plumber has crossed them at the wall rather than at the machine, which happens more often than it should. - Run a cold cycle after correcting them and confirm the code is gone. - If the hoses are right and the code stays, the temperature sensing is what to look at, and that is a visit rather than a five-minute check. ### Where this goes next The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), 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.
