Common Causes of the OC/OE Error

  1. Kinked or clogged drain hose – Twists or obstructions can prevent water from draining.
  2. Clogged drain filter or sump – Food debris and grease buildup can block water flow.
  3. Drain pump issue – A faulty or obstructed pump impeller can stop water from draining.
  4. Defective water inlet valve – If stuck open, it may continuously let water into the tub.
  5. Faulty main PCB (control board) – Can send incorrect signals to components.
  6. Overfill sensor malfunction – May incorrectly detect excess water.

Step-by-Step Troubleshooting for Samsung Dishwasher OC or OE Error Code

  1. Inspect the drain hose
    • Look for kinks, twists, or blockages between the dishwasher and the sink/drain connection.
    • Ensure it’s installed with a proper high loop to prevent backflow.
  2. Check sink drain and garbage disposal
    • If connected to a disposal, make sure the knockout plug is removed.
    • Run water in the sink to confirm your home plumbing drains properly.
  3. Clean the filters and sump
    • Remove and wash the dishwasher’s drain filter.
    • Clean the sump area to remove trapped food particles and grease.
  4. Inspect the drain pump
    • With power off and water removed, check the pump impeller for blockages or damage.
  5. Test the water inlet valve
    • If water continues to enter the dishwasher even when powered off, the valve is defective and should be replaced.
  6. Advanced checks
    • Measure drain pump resistance and verify voltage supply from the PCB.
    • Inspect the case break for blockages that may restrict water flow.
