Samsung washer OC: Excess water detected

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

Excess water detected.

OC is an overfill warning. If water continues entering, close the supply valves and arrange service.

First safe check

Check from outside the machine whether filling continues unexpectedly.

Applies to

THE DETAILS MATTER

Scope & troubleshooting notes

How to interpret this result

OC should not be treated as permission to open a water-filled front door. A high-water report is a condition, not proof that the inlet valve or water-level sensor must be replaced.
