Control water risk first
Leak warnings should be treated as water-risk checks. Stop restart attempts until visible water and the door or hose area are reviewed.
At-a-glance diagnosis
OC usually points to an over-level or overflow condition. Samsung dishwasher OC may also be searched as 0C or oE on some displays.
Cancel the cycle if safe, watch whether water keeps entering, and inspect for visible leaking around the door and under the sink.
Stop if water continues entering after cancellation, if water reaches the floor, or if OC returns immediately.
