Samsung Dryer Error Code Displayed — Troubleshooting Guide
When your Samsung dryer shows an error code on the digital display, it is communicating a specific diagnostic fault detected by the control board's monitoring circuits. Samsung dryers across the DV, DVE, DVG, and DVH series use alphanumeric error codes that identify both the affected system and the nature of the failure.
Samsung Dryer Error Code System
Samsung uses a consistent coding scheme across all dryer models. Each code consists of letters indicating the system followed by numbers indicating the specific fault. Unlike Whirlpool's F#E# format, Samsung combines both into shorter codes.
Complete Samsung Dryer Error Code Reference
| Code | System | Meaning | Severity |
|---|---|---|---|
| HE / HE1 | Heater | Heating element failure or overheating | High |
| HE2 | Heater | Heater relay stuck on | Critical — unplug immediately |
| tS / tO | Temperature | Temperature sensor open/short circuit | Medium |
| tE / tE1 / tE2 | Temperature | Thermistor failure | Medium |
| dC | Door | Door switch not confirming closed | Low |
| dE | Door | Door opened during cycle | Low |
| bE / bE2 | Button | Control panel button stuck | Low |
| AE / AE4 | Communication | Board-to-board communication failure | Medium |
| Et | Ventilation | Exhaust temperature too high (vent blocked) | High — fire risk |
| FE | Frequency | Power supply frequency abnormal | Low |
| 9C1 / 9E1 | Voltage | Low voltage detected | Low |
| Clg | Ventilation | Vent clogging indicator (preventive) | Maintenance |
| HC / HC4 | Gas | Gas ignition failure (gas models only) | High |

Entering Samsung Diagnostic Mode
- Power the dryer on (standby mode).
- Press and hold Dry Level + Time simultaneously for 3 seconds.
- Display shows "d" or "tSt" confirming diagnostic mode.
- The unit cycles through component tests: door switch, thermistor (displays temperature), heater relay (listen for click), motor, and moisture sensor.
- Press Power to exit.
Smart Care alternative: Open SmartThings app, select dryer, tap Support then Smart Care. The app reads diagnostic data via NFC or audio tones.
Troubleshooting Key Error Codes
HE / HE1 — Heating Element Failure
The control board energized the heater relay but does not detect expected temperature rise. Samsung electric dryers (DVE series) use a coiled Nichrome element, part DC47-00019A. Access from rear panel — 4 Phillips screws.
Testing: Disconnect element leads. Multimeter on resistance — normal: 7-20 ohms. OL = burned through. Also test each terminal to housing (ground) — any reading indicates fire-risk short. Replace immediately.
Parts Cost: $30-$80 | Professional Cost: $150-$280
tS / tE — Temperature Sensor/Thermistor Error
The thermistor (DC32-00007A) is an NTC resistor on the blower housing. At room temperature: approximately 10,000 ohms. If reading outside expected range, the board cannot regulate temperature.
Parts Cost: $8-$25 | Professional Cost: $120-$180
Et — Exhaust Temperature High
A fire safety warning — exhaust temperatures exceed approximately 200 degrees F. Samsung's Vent Sensor system (DVE45T6000+) provides preventive "Clg" code before reaching the "Et" shutdown threshold.
Immediate action: Stop using the dryer. Clean the entire exhaust path from dryer to exterior cap. Check for crushed duct, bird nests, or excessive duct length.
dC — Door Communication Error
The board is not receiving "door closed" signal from switch DC64-01538A. Causes: worn switch contacts, pinched wiring, or board input circuit damage from power surges.
9C1 / 9E1 — Low Voltage
Power supply dropped below 216V threshold. Check both breaker poles, look for corroded outlet connections or utility voltage issues. Samsung dryers require 240V within 10% tolerance.
AE — Communication Error
Main board and display board cannot communicate via ribbon cable. Reseat the ZIF connector. Models without VRT Plus vibration reduction are more susceptible to vibration-loosened connections.
Safety First — Know the Risks
Gas dryers carry carbon monoxide and explosion risk. Even electric dryers involve 240V circuits that can deliver a fatal shock. Our techs are licensed and insured — let them handle the risk.

Error Code Reset Procedure
- Unplug for 5 minutes (Samsung capacitors need full discharge time).
- Reconnect power.
- If code returns within first cycle, the fault still exists.
Some codes (HE2, Et) have a lockout feature — the dryer refuses to operate until the specific fault is resolved. This is a safety feature.

Error Code Priority Guide
Address multiple codes in this order:
- HE2 (relay stuck) — immediate safety hazard
- Et (vent blocked) — fire risk
- HE/HE1 (heater failure)
- tS/tE (thermistor)
- AE (communication)
- dC (door)
- bE (button stuck)
- 9C1 (voltage — external issue)

FAQ
Q: How do I clear a Samsung dryer error code?
Unplug for 5 full minutes, then reconnect. Samsung diagnostic memory stores the last 3-5 error events even through power cycles on newer models. Clearing does not fix the underlying problem.
Q: My Samsung dryer shows HE but still heats — should I worry?
Yes. An intermittent HE code with functional heating may indicate a partial element failure or arcing to ground. This is a fire hazard. Have it inspected promptly.
Q: What does Clg mean on my Samsung dryer?
Clg is the preventive vent-clogging indicator. The dryer still operates, but airflow has degraded. Clean your vent duct soon to prevent progression to the Et shutdown code.
Q: Can I run diagnostic mode without the display working?
Partially. Entering diagnostic mode still activates relay clicks and motor tests you can hear. A clicking pattern during the heater test without actual heating confirms element or relay failure even without visual display.
