Samsung Dryer Error Codes — Complete List

Samsung dryers report problems with the same short letter codes as the brand's washers — dC when the door won't register as shut, HC when the drum overheats, tS for a temperature reading it doesn't trust. One quirk to know up front: on the display an upside-down 'F' is actually a 't', so a code that looks like 'FS' belongs with the temperature group. Each verified guide below opens with the checks Samsung itself lists, which almost always start at the lint filter and exhaust vent.

• dC (dE, dF, do, d0, 1 DC, 1 dF) Your Samsung dryer shows dC when it can't confirm the door is shut and latched, so the drum won't turn — usually a door caught on laundry, a misaligned strike, or a tired latch switch rather than anything deep inside the machine.
• HC (hE, HC4, 1 HC) HC is Samsung's overheating warning: the dryer sensed the drum getting hotter than it should and cut the heat to stay safe — nine times out of ten because a clogged lint filter or blocked exhaust vent is trapping heat inside.
• tS (tE, tC, tO, t0, t5, tE3, tC5, 1 tC) tS on a Samsung dryer flags a problem with the temperature reading itself — the sensor is reporting a value the control doesn't trust — and the most common trigger is a clogged lint filter or vent throwing readings off rather than a dead part.
• 9C1 (9E, 2E, 9E1) 9C1 tells you the Samsung dryer is seeing abnormal electrical supply — too high, too low, or unstable — most often from an extension cord, a shared or miswired outlet, or a power cord that isn't fully seated.
• bE (bE2, bC2, 6E, 6E2, 6C2) bE means the Samsung dryer thinks one of its panel buttons is stuck down or being held — often just a sticky or debris-blocked button that frees up once you power off and work each one back and forth.
• AC (Et, AE, EEE, AE4, AE3, AE5, E3, 1 AC) AC means the Samsung dryer's internal boards have lost reliable communication with each other — frequently a one-off glitch that a full power-down clears, but a persistent AC points to a wiring or control-board fault.
• FC (FE, 1 FC) FC on a Samsung dryer signals an invalid power-source frequency — the incoming AC isn't the steady frequency the dryer expects — which usually clears on a restart but can point to a generator, converter, or supply problem if it sticks.
• Cg (Clg, C80, C8, C90, C9, C8o, C9o) Cg (and the C80 and C90 variants) is the result of Samsung's Vent Blockage self-test telling you the exhaust duct is clogged — the number roughly indicates how restricted it is — so the fix is to clean the lint filter and the entire vent line.
• 3C 3C is Samsung's motor error: the dryer isn't getting the drum motor to start, run, or report back correctly, so it stops the cycle — worth one power reset, but a repeat almost always means a motor or control fault for a technician.
• HC2 HC2 appears on gas Samsung dryers when the burner fails to ignite, so the drum turns but the clothes stay cold — and because every remaining cause is a gas component, this one goes to a licensed technician after a couple of safe checks.
• CL CL isn't a malfunction — it means Child Lock is switched on, which disables the Samsung dryer's control panel (and on some models locks the door) so buttons don't respond until you turn it back off.

Don't see your code?

A theme runs through these codes: several of them — HC, tS, and the Cg/C80/C90 vent-blockage test results — trace back to restricted airflow, so cleaning the lint screen and the full vent run is the first fix for all of them. HC2 is the exception we send straight to a technician, because it's a gas-ignition fault. And if your dryer flashes lights instead of showing a letter code, count the pattern against your model's manual rather than mapping it here.
