Samsung Washer Error Code 1DC
Door error on the upper washer
What the 1DC error code actually means
Your Samsung washer tried to open the upper drum door but could not confirm the door actually opened, so it stopped and displayed this error to prevent any unsafe situation. This is usually caused by a faulty door sensor, a broken connection in the door locking system, or a door latch that is stuck or not working correctly. A technician will need to check the door lock components to get the washer running again safely.
