Samsung washer ddC: Add Door closure warning

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

Add Door closure warning.

ddC concerns the small AddWash door rather than the main drum door. Close that opening securely before resuming.

First safe check

Check the Add Door and its visible latch for trapped clothing.

Applies to

Samsung washer families covered by the cited US guidance. Match the full model number and exact display; this is not an exact-model compatibility claim.

Before you start

Keep hands clear of a moving drum. Do not force a locked door or work on live wiring. Stop if water reaches an electrical connection.

THE DETAILS MATTER

Scope & troubleshooting notes

How to interpret this result

Opening the main door is not a substitute for checking the Add Door. A damaged mini-door latch needs repair; do not tape it shut or defeat its switch.
