Seeing **1 dC** on a Samsung washing machine narrows the problem to **door / door-lock error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **1 dC**. Search normalization stores it as **1DC** while preserving the characters a homeowner actually sees.

Door / door-lock error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 1DC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. If resolving 1 dC would require energized internal access, that is the point to hand the diagnosis to a qualified technician.
Request service if the door closes normally but the code returns, the latch will not release safely, or diagnosis requires testing the interlock, wiring, or control circuit. In a service visit for 1 dC, model-specific testing should follow the door / door-lock error circuit rather than treating the code as proof of one failed part.

Door / door-lock error.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **1 dC** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
Treat **1 dC** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Washer 1 dC** separate from same-looking codes used by other Samsung appliance families.
