Samsung Dishwasher Error Code OC: Over-level water error
Applies to Samsung dishwashers that show OC or OE, 0C on the display.
There is too much water in the dishwasher. Samsung classifies this as a functional error.
What this code means
Samsung's manual classifies over-level as a functional error, not a user-fixable one: the prescribed response is to cut water and power and call service.
The manufacturer's checks, in order
- Close the water supply valve.
- Switch the dishwasher's circuit breaker off.
Close the water supply valve, switch the break off, and contact a Samsung service center — do not keep running the machine.
