Samsung dishwasher OC error code
- Dishwasher
Samsung dishwasher OC (shown as 0C or oE on some displays) means the tub overfilled — more water entered than the control expected. A stuck-open inlet valve, failed float switch, or slow drain that backs water into the tub causes most OC codes. Turn off the water supply under the sink immediately if water is actively filling with the door closed.

How to fix OC
- Turn off the water supply valve under the sink if the tub is still filling.
- Unplug the dishwasher and bail standing water if the level is above the filter.
- Inspect the float switch in the tub bottom — it should move freely and click at the top of travel.
- Check the drain hose for clogs or a missing high loop that traps water in the tub.
- If OC returns, test the inlet valve — it may be stuck open and need replacement.
Call a pro when: Call a technician if water keeps entering with the valve closed or the float tests bad.
