Don't hesitate to call a professional. Addressing problems sooner rather than later helps to extend the life of the system and avoid contact with raw sewage. Most problems can be corrected with minor repairs. If a major repair or redesign of the system is required, King County will coordinate with the septic professional on permitting.
