If a Samsung washing machine shows **1dC4**, the verified Samsung meaning in this research set is **door / door-lock error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **1dC4**. Search normalization stores it as **1DC4** 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 1DC4 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 1dC4 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 1dC4 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 **1dC4** 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 **1dC4**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
Treat **1dC4** 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 1dC4** separate from same-looking codes used by other Samsung appliance families.
