Samsung Dryer Error Code dF
Unlike a simple door-open warning, this code means the control is getting an invalid door signal even when the door looks shut. A worn door switch or a loose connection in its circuit is the usual reason, so it tends to need a part rather than just a firmer close.
Also shown as: 1 dF
Common causes
- Door switch has failed
- Loose or open wiring in the door switch circuit
- Door not latching consistently, so the switch signal drops in and out
- Main control board fault
What to check, in order
- Open the door and firmly reclose it, then restart the cycle.
- Check that the latch engages positively every time and the door does not spring back open.
- Unplug the dryer for a couple of minutes, plug it back in, and try again.
- If the code returns with the door latching properly, book a repair for the door switch and its wiring.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code dF, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
