Seeing **dL** 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 recorded display form is **dL**. Search normalization stores it as **DL** 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 DL 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 dL 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. A repeatable dL event is more useful diagnostically than repeated resets, because it shows when the door / door-lock error check is failing.

Door / door-lock error.
Resetting can clear a temporary state, not a persistent issue. If **dL** comes back, preserve the code and move to the safe checks or model-specific service path.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **dL**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
The code alone is not enough to justify a part. **dL** 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 dL** separate from same-looking codes used by other Samsung appliance families.
