Seeing **DC3** on a Samsung washing machine narrows the problem to **addwash / add door error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. 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 display variants retained for this lookup are **dC3, DC3**. They are grouped under normalized key **DC3** so spacing, case, and separator differences do not create duplicate repair meanings.

AddWash / Add Door error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 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.

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 DC3 disappears.
Once DC3 has returned after the safe checks, 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. Preserve any accompanying noise, water level, temperature, or operating-stage details for the technician.

Resetting can clear a temporary state, not a persistent issue. If **DC3** comes back, preserve the code and move to the safe checks or model-specific service path.
Do not keep operating the appliance through a hazardous symptom just to see whether **DC3** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
No. **DC3** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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 DC3** separate from same-looking codes used by other Samsung appliance families.
