The **0C** display on a Samsung washing machine points to **overflow / excessive water error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **0C**. Search normalization stores it as **0C** while preserving the characters a homeowner actually sees.

Quick answer
Overflow / excessive water error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 0C 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
The **0C** display on a Samsung washing machine points to **overflow / excessive water error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **0C**. Search normalization stores it as **0C** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
While 0C is active, the appliance may enter a protective drain or stop condition.
When the 0C condition is present, moisture can be present inside a base pan even when no puddle is visible outside.
While 0C is active, the code may return after a fill, drain, defrost, ice-making, or water-dispensing event.
When the 0C condition is present, 0C appears during the washer stage associated with overflow / excessive water error.
On affected Samsung washing machine models, the cycle can 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 0C, stop use if water is near electrical parts or leaving the cabinet.
A safe owner-level check is to verify only visible user-accessible hoses, filters, doors, gaskets, and water connections.
As an external check for 0C, check for excess suds where detergent is involved.
A safe owner-level check is to do not defeat or dry out a leak sensor repeatedly without locating why moisture reached it.
With 0C recorded, 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. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. For 0C, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.
Get help
When to request repair service
For 0C, the service threshold is straightforward: Persistent leak/overflow detection needs the moisture source corrected. Internal leak tracing, valves, sensors, pumps, or wiring may require service. Bring the exact model number and a photo of the display so the diagnosis stays tied to the documented Samsung code.

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 **0C** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **0C** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **0C** 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 0C** separate from same-looking codes used by other Samsung appliance families.
