Samsung tumble dryer DC error code
What DC means on a Samsung tumble dryer
Door not recognised as closed.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When a Samsung tumble dryer shows the DC code, it means the dryer does not recognise that the door is closed. Because it thinks the door is open, it will usually refuse to start a programme, and some owners also notice the dryer being noisy when this code appears.
Engineers sometimes find that the door switch inside the dryer has failed, or that it has become dirty or worked loose so it no longer senses the door shutting. Engineers also sometimes find that the small pin on the door, which presses the switch when you close it, has snapped off. Some owners notice beforehand that the dryer only starts now and then, or only if they push on the door.
An engineer will usually check the door and its pin for damage and test whether the dryer runs when the switch is operated. Depending on what they find, they clean and reseat the switch, fit a new door switch, or replace the door itself when the pin is part of it. These parts often have to be ordered, so the repair may be finished at a second visit.

Before you check anything yourself
- Switch the tumble dryer off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the tumble dryer apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
