Samsung Dishwasher PC Error Code

Samsung’s PC guidance is one restart attempt, followed by service if the code remains. Keep the homeowner scope at the controls and do not open diverter, valve, pump, or wiring areas.

Applies to Samsung dishwasher with digital display

What the appliance detected

Detected condition

The Zone Wash function is not operating correctly.

What may contribute

Possible causes

  • The dishwasher detected that the Zone Wash function did not operate correctly.
  • An internal wash-distribution, sensing, control, or wiring condition may require qualified diagnosis if PC returns.

Start conservatively

Safe preliminary checks

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

  1. Confirm the model actually has Zone Wash

    • Record PC and confirm the full model number.
    • Use the exact Samsung manual to verify the Zone Wash feature and normal control operation.

  2. Try the Samsung-documented restart once

    • Turn the dishwasher off, then try to start the cycle again once.
    • If PC returns, stop troubleshooting at the user controls.

  3. Escalate a persistent PC code

    • Request Samsung service if the code remains or returns.
    • Leave internal wash-distribution, pump, valve, sensor, and wiring diagnosis to a technician.

Actions not recommended

  • Do not access or force internal diverter, pump, valve, or spray-system parts.
  • Do not run hidden service modes or bypass sensors.
  • Do not replace parts based on PC alone.

When to stop and request service

  • PC returns after the single documented restart.
  • Zone Wash does not operate normally or unusual noises/leaks accompany the code.
  • Any next step requires internal water-distribution, sensor, wiring, or control access.
