Samsung Washer code **OC** is associated with **overflow / excessive water 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 **OC**. Search normalization stores it as **OC** 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 OC 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 **OC** is associated with **overflow / excessive water 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.

Signs
Symptoms you may notice
OC can be accompanied by this pattern: the appliance may enter a protective drain or stop condition.
While OC is active, moisture can be present inside a base pan even when no puddle is visible outside.
When the OC condition is present, the code can return after a fill, drain, defrost, ice-making, or water-dispensing event.
The OC display becomes more meaningful if oC appears during the washer stage associated with overflow / excessive water error.
The OC display becomes more meaningful if 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.
For OC, start by doing this: stop use if water is near electrical parts or leaving the cabinet.
As an external check for OC, check only visible user-accessible hoses, filters, doors, gaskets, and water connections.
A safe owner-level check is to check for excess suds where detergent is involved.
The next non-invasive check is to do not defeat or dry out a leak sensor repeatedly without locating why moisture reached it.
The next non-invasive check is to record the code and the cycle stage where it appears.
The next non-invasive check is to check owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Safety takes priority over clearing OC. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.

When to request repair service
Once OC has returned after the safe checks, Persistent leak/overflow detection needs the moisture source corrected. Internal leak tracing, valves, sensors, pumps, or wiring may require service. Preserve any accompanying noise, water level, temperature, or operating-stage details for the technician.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Resetting can clear a temporary state, not a persistent issue. If **OC** comes back, preserve the code and move to the safe checks or model-specific service path.
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.
Treat **OC** 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 OC** separate from same-looking codes used by other Samsung appliance families.
