Samsung Dryer Error Codes
Samsung dryers report tE, hE, dC, and vent blockage codes. Steam models add extra sensors at the drum and duct.
General troubleshooting
Try these checks before opening a specific error code page—they resolve many Samsung dryer faults without parts.
- 1Clean lint filter and sensor bars inside the drum
- 2Inspect flexible vent behind the dryer for crushing or disconnection
- 3On gas models DV45K6500GV and similar, confirm LP or natural gas orifice is correct
- 4Run a Time Dry cycle to bypass moisture sensors during testing
- 5Verify the dryer cord matches the outlet type (3-wire vs 4-wire)
Common symptoms
Owners often search for a code after noticing one of these issues on their Samsung dryer:
- tE or hE heating element or gas ignition faults
- Clothes damp with vent restriction warnings
- dC door open codes when the latch switch fails
- 9C1 or 9E power supply errors after installation
- Sensor Dry ends early leaving items damp
All Samsung dryer error codes
| Code | What it means | Guide |
|---|---|---|
| 3C | Drive motor position sensor fault3C on Samsung dryers indicates the drive motor hall sensor did not report valid rotor position at startup. The drum will not turn until the inverter receives position feedback from the motor. | View fix → |
| 9C1 | Abnormal supply voltage detected9C1 (9E, 2E, 9E1 family) logs when incoming voltage is too low, too high, or one leg of 240 V is missing. Electric dryers need both hot lines for heat and motor—single-leg supply triggers 9C1 within seconds of start. | View fix → |
| 9C2 | Secondary voltage irregularity fault9C2 (9E2, 19C2) is the companion voltage error to 9C1—often logged when voltage recovers briefly then drops again during motor inrush. Samsung protects the inverter by locking out until supply stabilizes. | View fix → |
| AC | Electronic control communication faultAC (1 AC, AE3 variants) indicates the main PCB cannot exchange data with a sub-module—display, motor driver, or moisture sensor board. The dryer may beep and halt with time frozen on the LED. | View fix → |
| AE | Internal board communication failureAE (Et, EEE, E3 variants) is a Communication Error between the display, main control, and motor driver. Cycles may freeze mid-dry or show garbled remaining time until the link restores. | View fix → |
| BE | Jammed touch key on control panelbE displays with capital E on many Samsung dryer panels when a capacitive key reads continuously pressed. Functionally identical to the jammed-button bE family—Samsung uses mixed casing on different firmware builds. | View fix → |
| CE | Compressor or heat-pump cooling faultCE on Samsung heat-pump and hybrid dryers indicates a cooling error—the refrigerant loop or auxiliary fan cannot shed heat fast enough. Vented electric models rarely show CE; verify your dryer type in the manual. | View fix → |
| CL9 | Exhaust vent restriction at ninety percentCL9 (C9 variant) reports roughly ninety percent exhaust airflow restriction on Samsung vent-sense models. The dryer measures blower strain; at this level heat cycles shorten and CL9 warns before a full block triggers shutdown. | View fix → |
| D90 | Vent airflow blocked about ninety percentD90 is Samsung's vent blockage warning at roughly ninety percent restriction. Heat may cycle off early and drying times stretch far beyond normal until airflow is restored. | View fix → |
| DC | Door circuit open at cycle startDC on Samsung dryers means the door switch circuit read open when the control expected closed. Heat and drum motion are blocked until the latch confirms the door is sealed—distinct from washer DC imbalance code. | View fix → |
| DE | Door switch not confirming closeddE stops the drum and heat because the door switch never reads closed at cycle start. Samsung dryers require a confirmed latch before the motor and heater energize—distinct from washer dE but same door-lock logic. | View fix → |
| EE | Control EEPROM memory errorEE signals EEPROM failure on the main control—the stored cycle profiles and calibration data read invalid. The display may show random characters or refuse every cycle until the board passes memory check. | View fix → |
| FC | Power frequency out of specificationFC groups with FE as a Frequency Error on Samsung laundry electronics. The inverter or main board detects AC frequency outside the narrow band expected for motor and heat control—common after generator use or bad breaker contacts. | View fix → |
| FE | AC line frequency sensing faultFE is grouped with FC as a Frequency Error—the control detects mains frequency outside tolerance or the sensing circuit failed. Electric dryers on unstable supply or import models on wrong grids see FE at startup. | View fix → |
| H01 | Gas supply not detected on gas modelsH01 appears on Samsung gas dryers when the control does not detect gas supply pressure or the gas valve failed to open during a heat request. Electric models never show H01—confirm your unit is gas before troubleshooting fuel. | View fix → |
| HC | Heating circuit overheat—exhaust or internal thermal limit trippedSamsung HC indicates a heating circuit overheat condition—the control detected exhaust or cabinet temperature above safe limits and shut down heat to prevent fire hazard. On electric models DV45K6500EV and DVE45R6100C, HC most often follows restricted vent airflow that traps heat in the drum and duct, but can also mean a failed thermistor, blown thermal fuse DC47-00016A, or heating element short to ground. HC is distinct from tE (thermistor fault code) and dC (door open)—address vent hygiene before replacing electrical parts. | View fix → |
| HE | Heating system not reaching target exhaust tempHE (hE on some displays) logs when exhaust temperature fails to climb during a heat cycle. Samsung disables the element or gas valve as protection—restricted vent airflow is the most common trigger before any part failure. | View fix → |
| NF | Steam water supply not detectednF (Not Filling) on Samsung steam dryers appears when the steam generator valve opens but no water arrives—similar to washer 4E but for the auxiliary steam line. Non-steam models may show nF for other fill-related faults; confirm steam kit installation. | View fix → |
| TE | Exhaust thermistor signal out of rangetE appears when the thermistor on the blower housing reports resistance the board considers impossible—open, shorted, or stuck. Heat cycles abort because Samsung cannot safely regulate exhaust temperature without valid feedback. | View fix → |
