Quick answer
ddC and dC3 mean the Add Door on a Samsung washer is not detected as closed and locked.
Model compatibility: Samsung reuses codes across series and model years, so ddC / dC3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Add Door error: the Add Door is not detected as closed and locked.
ddC or dC3 on a Samsung washer means the Add Door is not detected as closed and locked. It applies to washers that have an Add Door.
What to check
Look at the latch first: it should be fixed firmly. Then see that no clothing or other item is trapped in the Add Door and that the Add Door sits shut and secured. Damage to the Add Door or latch, or a code you cannot clear, means requesting service.
Call (310) 896-4231 about a damaged latch on a Samsung washer in Los Angeles. Read washer repair for more. Keep the code, model number and what you tried ready.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
