What does this error code mean?
Samsung dishwasher error code OC usually indicates an overfill, water-level, or drainage condition. It can overlap with leak warnings if water, foam, or drainage backup is affecting the base or level detection.

- Clean the accessible filter and check the drain hose is not kinked.
- Stop if water is visible under the appliance or OC returns.

Safety boundary: Disconnect power before checks. Do not run the appliance if water may be reaching electrical parts.
What not to do
- Do not add more detergent to clear the code.
- Do not keep running the dishwasher if foam or water is escaping.
- Do not remove panels to inspect sensors.
Reset steps
- Only restart after foam has cleared, filters are refitted, and the area is dry.
- Run one short test if there is no leak and the appliance drains normally.
- Stop if OC returns.
Intermittent vs persistent faults
A one-off OC after detergent misuse may clear, but repeated OC should be diagnosed.

Call an appliance engineer if OC returns after detergent, filter, and drain checks, or if water-level, inlet, or control diagnosis may be needed.
Safety warning
