Can I fix Samsung dishwasher error code OC myself?

Often, yes. Safe first checks: Close the water supply valve and switch the dishwasher off If the code returns, or water is sitting above the filter and not draining, request service from Samsung rather than running it again.

Samsung Dishwasher error code OC

Also shown as: 0C, oE

What it means

Over-level water error - there is more water in the dishwasher than there should be.

Likely causes

There is more water in the dishwasher than there should be

Safety first: switch the appliance off and unplug it (or turn it off at the circuit breaker) before you check anything. If water is involved, close the water supply valve too. Never open panels or touch internal wiring. Anything that involves gas lines, refrigerant or sealed systems, or mains-voltage wiring is a job for a professional - not a home fix.

When to call a pro

If the code returns, or water is sitting above the filter and not draining, request service from Samsung rather than running it again.

Repair or replace?

Try the safe checks first - many codes clear with a clean filter, a straight hose or a balanced load, and those cost nothing. If the code comes back, a service call typically costs $50-$150 for the visit and diagnosis (Angi puts an average service call at $50-$100; Sears lists a $90-$150 diagnostic fee). Get the full repair quote before you decide. If the machine is old and the quote is a large part of the price of a new one, replacing usually makes more sense than repairing.
