Samsung Dryer Error Codes

Samsung dryers are built with self-diagnostic systems that flash error codes when something goes wrong. These codes are your first clue to pinpoint and solve the problem, whether it’s a clogged vent or a control board issue. Learning what each code means and how to address it can save time, money, and frustration.

Below you’ll find clear explanations for the most common Samsung dryer error codes, along with practical troubleshooting steps for each. If your dryer is flashing an unfamiliar message, this guide will help you decode and fix it.

Understanding Samsung Dryer Error Codes

Samsung dryers display error codes on the control panel when they detect a fault. Each code corresponds to a specific problem: electrical, mechanical, or related to airflow. You'll usually see these codes as a combination of letters and numbers, like "HE" or "tE". Recognizing these codes is critical for safe and effective repairs.

Most codes appear after the dryer beeps or when it fails to start or finish a cycle. Some are temporary and clear after power cycling, while others signal deeper issues. Keep your model’s user manual handy, as certain codes vary by model. However, many codes are standardized across Samsung's lineup, especially in models produced after 2016.

Heating Error Codes: HE, HE1, HE2

Heating-related codes are among the most common on Samsung dryers. "HE" (or "HE1/HE2" on some models) points to a problem with the heating element or related circuits. If the dryer runs but doesn’t heat, or stops mid-cycle, this code often pops up.

• HE: General heating error. Likely causes include a faulty heating element, blown thermal fuse, or loose wiring. Unplug the dryer, check the back panel, and look for burnt wires or a broken element coil.
• HE1: The dryer overheated. Clean the lint filter, check for a clogged vent, and ensure proper airflow. Overheating can also trip the thermal cutoff, which might need replacement.
• HE2: The drying temperature is too low, suggesting the element isn’t heating up. Test continuity on the element with a multimeter and replace if needed.

Temperature Sensor and Thermistor Codes: tE, tE1, tE2, tE3

Codes starting with "tE" refer to temperature sensor or thermistor faults. The dryer relies on temperature readings to regulate heat. If the sensor fails, you’ll see these codes and the dryer might stop working or dry clothes poorly.

• tE: General temperature sensor error. Unplug the dryer and inspect wiring to the thermistor. Disconnect and test the thermistor with a multimeter (expect about 10k ohms at room temperature). Replace if readings are off.
• tE1/tE2/tE3: Specific variants for inlet, outlet, or drum temperature sensors. Follow the same steps: check for loose connectors, broken wires, or replace the faulty sensor.

Always replace with genuine Samsung parts to avoid further error codes.

Moisture Sensor and Drying Issues: dE, dC, dF

Dryers use moisture sensors to judge when clothes are dry. Error codes like "dE" or "dC" often mean there’s a problem with the door switch or moisture detection circuit.

• dE: Door error. The door switch might not be engaging, or the latch is misaligned. Press firmly on the door, listen for the click, and try starting the cycle again. Inspect the latch for debris or damage.
• dC/dF: Sensor or circuit failure. The wiring to the moisture sensor bars (inside the drum, often silver strips) may be dirty or disconnected. Clean the sensor bars with rubbing alcohol to remove any buildup, and check for loose connectors in the control panel.

Ventilation and Airflow Errors: FE, 9C1, 9E, C80, C90

Blocked airflow is a leading cause of drying problems. Samsung dryers track airflow and show codes like "FE", "C80", or "C90" if they sense poor ventilation.

• FE: Too much lint or debris restricts the vent. Pull the dryer out, disconnect the vent hose, and clear out any lint with a vent brush. Don’t forget to check the outside vent cap for blockages.
• C80/C90: Indicates 80% or 90% vent blockage, respectively. Even a partial clog can trip these codes and cause long dry times or overheating. Clean both the duct inside the wall and the hose. Replace crushed or kinked hoses.
• 9C1/9E: Electrical supply issues, often relating to unstable power or a weak plug connection. Make sure the dryer’s outlet is delivering a consistent 240V. Poor wiring can cause the dryer to run erratically and trigger airflow sensors falsely.

Motor and Drum Issues: bE, bE2, bE3, 3E

If your Samsung dryer gives a "bE" or "3E" code, it’s often related to the motor or the start switch. These errors tend to show up when the drum fails to spin or the dryer hums but doesn’t start.

• bE: Button error. One of the control panel buttons may be stuck or registering continuous input. Tap each button several times to free it. If the code persists, unplug the dryer for 5 minutes and retry.
• bE2/bE3: More specific button faults or motor relay problems. If you’ve ruled out the panel, the control board may need inspection or replacement.
• 3E: Motor error. Listen for a humming sound or check if the drum is hard to turn by hand. If so, the motor or the belt may be jammed, worn, or broken. Access the drum, check the belt for cracks, and ensure the motor pulley spins freely.

Communication and Control Board Errors: CE, AC, AE

Codes like "CE" or "AE" suggest the dryer’s main control board is having trouble communicating with sensors or sub-boards. These errors are less common but can be tricky to resolve without professional help.

• CE: Communication error between boards. Try unplugging the dryer and waiting 10 minutes before restarting. Inspect wiring harnesses for loose or damaged connectors. If the code returns, the main PCB may be failing.
• AC/AE: Internal control problem, usually requiring a new main board. Surges or moisture damage inside the control panel are sometimes to blame. If your dryer is under warranty, this is a good time to call Samsung support.
