Error Code — With Known Triggering Event
This guide assists in diagnosing error codes that appeared immediately following a specific action, such as a product selection attempt or a power fluctuation.
- Error codes persist after addressing the identified physical cause and clearing the error memory: Do not replace the control board. Re-inspect harness connections and sensor states. Escalate if codes persist after second inspection.
- If error codes persist after addressing the identified physical cause and clearing the error memory, escalate to a qualified technician for advanced board diagnostics.
