What to check, in order
- Close the door firmly
Check no laundry is caught in it, and that it closes and latches properly.
- Check the latch
Make sure it's securely fixed and not damaged.
- Check the Child Lock
Samsung UK says an active Child Lock can bring up dC or dE when you open the door, even if the dryer isn't running.
- Reset it
Unplug for at least 30 seconds and try again.
When to call an engineer
If it comes back, or for dF. Samsung UK says dF means checking the door lock or switch wiring for loose or damaged connections, and Samsung Australia says the whole door lock and switch may need replacing.
Parts people end up buying
Only if the checks above point to a part. Match it to your model number first: it's on a label inside the door, around the door frame or on the back.
