An update is running
dn tells you the washer is downloading an update. For the duration no control responds, the dial included. The update takes about 15 minutes, and dn goes away once it ends.
What Samsung advises
Keep the washer powered on until the download finishes.
Request service if dn has been showing for more than 30 minutes while the washer stayed on and Wi-Fi had no connection problems.
If dn outlasts the half hour, call (415) 969-6153 for Samsung washer help around San Francisco. Samsung washer repair is on the linked page. Tell us how long it has been showing and that Wi-Fi works.
Model compatibility: Samsung reuses codes across series and model years, so dn may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
