The **SC** display on a Samsung dishwasher points to **drain error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. 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 **SC**. Search normalization stores it as **SC** while preserving the characters a homeowner actually sees.

Drain error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so SC 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. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. For SC, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.
If the accessible drain path is clear but the code returns, the pump, internal hose, water-level sensing, wiring, or control may need model-specific testing. If SC keeps returning, record the stage at which it reappears so the technician can test the drain error path instead of replacing parts by guesswork.

Drain error.
Resetting can clear a temporary state, not a persistent issue. If **SC** 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 **SC**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **SC** before replacing anything.
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 **Dishwasher SC** separate from same-looking codes used by other Samsung appliance families.
