If you have the specific showing on your L818FM1 display, share it – I can give precise diagnostic steps.
The presser foot safety switch did not return to the correct position or is disconnected. Troubleshooting:
The programmable control board acts as the machine's central nervous system, managing everything from motor speed and needle positioning to automatic thread trimming and reverse stitching. When the system detects an anomaly—such as a mechanical jam, electrical fault, or sensor failure—it halts operation and displays a specific error code on the panel.
While Siruba does not typically release a public PDF specifically titled "Error List 2021" for this model, the machine operates on a standard error code system used across the Siruba/Lockstitch direct-drive lineup.

Since error codes vary by control system version, the best source is always the . Recommended sources:
Issue with the motor encoder connector or data cannot be read. Needle Position Error Needle bar is not in the correct position. ERR17 Emergency Switch The emergency stop switch has been pressed. ERR34 Power Off System has detected a power-down state. Key Features of the L818-M1
The machine does not know where the needle is positioned. If you have the specific showing on your
Excessive current is flowing, usually caused by severe mechanical resistance or an electrical short within the motor. Troubleshooting:
Ensure the needle is not stuck in the fabric. Use the handwheel to position the needle at the highest point and turn the machine off and on. 3. Safety Switch / Emergency Stop (ERR17)
The is a high-performance, single-needle industrial lockstitch sewing machine, widely recognized for its durability, speed, and precision. It is designed for volume production, featuring a programmable control panel (often the L-600 series) that allows for stitch programming and process automation.
Does the error appear or when you start sewing ? What is the exact error code (e.g., ERR3 or E003)? When the system detects an anomaly—such as a
The motor is struggling to turn, usually because the machine is locked, jammed, or too heavy for the current settings. Troubleshooting:
Turn the machine off and on to reset the drive system. Check that the needle is in the upper position, and check the power supply (220V/110V).
The is a highly reliable, high-speed single-needle industrial lockstitch sewing machine. Equipped with an integrated direct-drive servo motor and an electronic control box, it delivers precision stitching for thin to medium-heavy fabrics. However, when technical faults interrupt your workflow, the machine displays specific error codes on its programming panel.
