Seeing **DC1** 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 useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The display variants retained for this lookup are **dC1, DC1**. They are grouped under normalized key **DC1** so spacing, case, and separator differences do not create duplicate repair meanings.

Door / door-lock error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so DC1 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. Do not bypass a safety device merely to see whether DC1 disappears.
If the owner-accessible checks do not clear DC1, 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. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Door / door-lock error.
Resetting can clear a temporary state, not a persistent issue. If **DC1** comes back, preserve the code and move to the safe checks or model-specific service path.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **DC1** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **DC1** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
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 DC1** separate from same-looking codes used by other Samsung appliance families.
