Samsung Dishwasher OC / 0C / oE Error Code

OC/0C/oE is an over-level water condition. Treat it as a water-safety issue and avoid repeated cycles until drainage, supply, or service context is addressed.

Applies to Samsung dishwasher with digital display

What the appliance detected

Detected condition

Samsung identifies OC, 0C, and oE as over-level water errors: there is more water in the dishwasher than there should be.

What may contribute

Possible causes

  • The dishwasher has more water than expected.
  • Drainage or overflow handling may not be working correctly.
  • A water-level or fill condition may require service if the code returns.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the exact display

    • Photograph or write down whether the display shows OC, 0C, oE, or a similar-looking OE.
    • Confirm the exact model and owner manual before taking action.

  2. Stop for leaks or overflow risk

    • Stop use if water is leaking, rising, or pooling near electrical parts.
    • Shut off the water supply if safe and avoid starting another cycle until the condition is understood.

  3. Use drain-related checks only within the manual

    • Check accessible filter and visible drain conditions if the owner manual supports those steps.
    • Request service if the code returns or if water level, fill, or drain behavior seems abnormal.

Actions not recommended

  • Do not keep running cycles with an over-level water code.
  • Do not remove panels, access water-level sensors, replace valves, or test electrical parts.
  • Do not ignore water near flooring or electrical areas.

When to stop and request service

  • Request Samsung service if OC, 0C, or oE returns after accessible checks.
  • Use qualified help for suspected fill, drain, overflow, or installation issues.
  • Stop immediately for active leaking, water near electrical components, or any internal access requirement.
