Important Safety Note

Before attempting any troubleshooting or repair steps, always unplug your Samsung AirDresser from the power outlet. Exercise extreme caution when inspecting internal components. If you are uncomfortable performing any step, it’s best to contact a qualified technician.

General Troubleshooting Tips Before You Start

Sometimes an error code is triggered by a simple oversight. Before digging into specific codes, try these basic checks:

• Ensure the door is completely closed. Give it a firm push.
• Check the water tanks. Make sure the clean water tank has enough water and the drain tank is empty (or correctly seated if it’s an auto-drain model).
• Verify the unit is properly plugged in.
• Check your home’s power supply. Ensure there hasn’t been a recent power outage or tripped breaker affecting the outlet.
• Gently reset the unit. Unplug it for 5-10 minutes, then plug it back in and try operating it again.

Samsung AirDresser Error Codes Explained

Here is a breakdown of common error codes you might encounter, their likely meaning, and troubleshooting steps, starting with the simplest potential causes.

dc: Door Lock Error

• Meaning: The AirDresser detects that the door is open when you tried to start a cycle, or there’s an issue with the door latch or sensor.
• Troubleshooting:
  1. Ensure the door is fully and firmly closed. Try opening and closing it again.
  2. Check the door latch area for any obstructions preventing it from closing properly.
  3. Inspect the door sensor area (usually on the door frame and the door itself) for visible damage or obstructions.
  4. Check the wiring connection to the door sensor circuit (requires accessing internal components – if uncomfortable, call a technician). Look for loose or damaged wires.
  5. Inspect the door lock assembly itself.
  6. If basic checks fail, the issue may lie with the main control board (PCB), requiring professional diagnosis and repair.

Sensor Errors (tC series):

These codes generally indicate an issue with a specific temperature or level sensor not reporting correctly. Checking connections is a common first step. Note: Checking sensor resistance requires a multimeter and technical knowledge.

• tC5: Compressor Sensor Error

    3. The issue could be with the main control board (PBA) or the inverter PBA.
• AC: Communication Error
  • Meaning: The main control board (PBA) and the display control board (PBA) are not communicating properly.
  • Troubleshooting:
    1. Check the wire harness connection between the main PBA and the display PBA. Ensure it is secure and undamaged.
    2. The issue could be with either the main PBA or the display PBA.
    3. Replacing the display control or the main PBA may be necessary.
• AC6: Communication Failure (Main PCB & Inverter PCB)
