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

Overflow 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.

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. If resolving OC would require energized internal access, that is the point to hand the diagnosis to a qualified technician.
Persistent leak/overflow detection needs the moisture source corrected. Internal leak tracing, valves, sensors, pumps, or wiring may require service. If OC keeps returning, record the stage at which it reappears so the technician can test the overflow error path instead of replacing parts by guesswork.

Overflow error.
You can try the one reset Samsung documents for the model, but **OC** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
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.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **OC** 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 OC** separate from same-looking codes used by other Samsung appliance families.
