What OC / OE means
Samsung identifies OC, 0C, and OE as an over-level water error: the machine senses excess water.
What you may notice

- 03A blocked disposer or air gap

Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Stop active filling
Close the supply valve if water keeps entering.
Clean the filter
Remove food debris from the user-accessible filter.
Inspect the drain path
Check the sink, disposer, air gap, and accessible hose.
Restart once
After normal drainage is restored, cycle power for 30 seconds.
Know where to stop
Shut off water for uncontrolled filling. Do not remove a hardwired dishwasher while energized.
When to call a technician or support
Request Samsung service if the code returns after the safe checks above or if leaking, overheating, electrical odor, or abnormal mechanical noise is present.
When you call, have the exact product or vehicle model, model year where relevant, the complete code or symbol, and when it appeared.
