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

    Press CANCEL to clear the display. Set time of day. Refer to the Owner's Manual for more detailed information. If you would like to download or view product literature for your appliance, please visit our Manuals and Literature page.

    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.

Escalation point

Stop and arrange service when

  • The code returns after the cited user-accessible checks or the official source directs professional service.
  • The equipment leaks, smells burned or of gas, smokes, sparks, overheats, or trips a breaker.
