Samsung Washer code **SC** is associated with **drainage error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **SC**. Search normalization stores it as **SC** while preserving the characters a homeowner actually sees.

Quick answer
Drainage 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.
Plain language
What this code means
Samsung Washer code **SC** is associated with **drainage error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **SC**. Search normalization stores it as **SC** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
While SC is active, water or condensate can remain where the appliance expects it to be removed.
When the SC condition is present, a cycle can pause, extend, or stop during the drain stage.
On affected Samsung washing machine models, a pump may run longer than normal or sound different while the code is active.
On affected Samsung washing machine models, sC appears during the washer stage associated with drainage error.
A symptom that fits SC is that the cycle may pause, stop, retry, drain, or refuse to advance until the condition is cleared.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
As an external check for SC, check and clean only the user-accessible filter or drain area described in the model manual.
A safe owner-level check is to check the external drain hose for kinks, freezing, crushing, or an incorrect installation height.
With SC recorded, verify the household standpipe, sink, disposal connection, or condensate path is not restricted.
With SC recorded, record whether the pump runs and whether fluid actually leaves the appliance.
Before requesting service for SC, record the code and the cycle stage where it appears.
A safe owner-level check is to check owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. When working around a washing machine that shows SC, keep the checks external and non-invasive. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.

When to request repair service
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. A repeatable SC event is more useful diagnostically than repeated resets, because it shows when the drainage error check is failing.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **SC** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
The code alone is not enough to justify a part. **SC** 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 SC** separate from same-looking codes used by other Samsung appliance families.
