What OC usually means
OC usually points to an over-level or overflow condition.
Codes can vary by exact Samsung dishwasher model number, production year, and regional design. Use this as first-pass guidance, then confirm the model-specific manual or manufacturer support page before opening panels or replacing parts.
First checks
Cancel the cycle if safe, watch whether water keeps entering, and inspect for visible leaking around the door and under the sink.
Overflow warnings can be tied to inlet flow, drain restrictions, suds, or sensing behavior, so repeated cycles are not useful.
- Shut off water if filling does not stop.
- Check for foam or detergent overdose.
- Inspect the sink drain path.
- Keep power and standing water separated.
When to stop
Stop if water continues entering after cancellation, if water reaches the floor, or if OC returns immediately.
Keep the full model number, exact OC display text, cycle name, and timing ready before contacting Samsung support or a qualified technician.
Model numbers affected
Commonly searched model families include built-in dishwashers, front-control dishwashers, top-control dishwashers, and compact dishwashers.
This is not a confirmed model-number list. Match the exact code to the full model number on the appliance tag before ordering parts, opening panels, or booking service.
