Decision path

Safe checks, in order

  1. 1

    Confirm code and model scope

    Compare the complete display and full model number with the cited manufacturer page or manual before applying any troubleshooting instruction.

    Expected: The official source explicitly covers the displayed code and product family.

    If not resolved: Contact manufacturer support with the full model and serial number.

  2. 2

    Follow the official owner checks

    Touch start and then cancel/reset. Tap on the float cover (plastic cover like an upside-down cup in the front left corner of the dishwasher floor) to un-stick the float. Check the sump area at the back bottom of the tub (looks like an upside-down silverware basket) for debris.

    Expected: Only the user-accessible condition identified by the official source is corrected.

    If not resolved: Stop repeated resets and arrange qualified service if the code returns or the source directs service.

Reset and test

Important: A reset may clear the display but cannot repair the underlying condition; follow only the exact model-specific manufacturer procedure.
