If you encounter a specific error code not covered in this guide, or if you need help finding a particular parameter number to adjust your deceleration time, let me know. I can provide the or wiring adjustments needed for your specific control box model. Share public link
If you have a specific error code in mind for the Siruba L818FM1, providing that code could help in giving a more precise solution or guidance.
Turn off the system and check the motor encoder connector. If the connection is secure but the error persists, the motor may need service. Abnormal over-current siruba l818fm1 error list work
Remove the needle plate and blow out lint from the feed dogs.
The following codes are sorted by their numeric sequence for easy reference. Most minor errors can be cleared by pressing the RESET key on the control panel.
If the machine runs but does not function correctly, check these specific areas:
