The machine failed to stop at the correct needle position (up or down). | 1. Check the handwheel magnet and sensor alignment. 2. Inspect the 9-pin signal cable for loose connections. 3. If an external stop positioner is used, ensure it's properly connected. | | | Foot Pedal Signal Not Detected
Check the oil level in the oil pan; low oil can cause heat and mechanical issues that trigger motor errors.
| Error Code | Description / Cause | ✅ How to Fix & Work Instructions | | :--- | :--- | :--- | | | Emergency Stop switch is pressed. | Press the RESET key to eliminate the error. | | 11 | Pause switch is pressed. | Press RESET to clear the error. Move the presser foot to continue sewing. | | 12 | Pause switch is active. | Press RESET , then press the foot pedal to the 2nd gear position to perform the origin detection. | | 15 | Emergency Stop switch is faulty (contact failure) during power-on. | Turn off the power. Check the connection of the main board socket P9 . | | 16 | Emergency Stop switch contact failure during power-on. | Turn off the power. Check the main board socket P9 . | | 25 | Foot pedal switch in 1st gear position (presser foot switch) during power-on. | Turn off power. Check the foot pedal switch sensor. | | 35 | Foot pedal switch in 2nd gear position (start switch) during power-on. | Turn off power. Check the foot pedal switch. | | 50 | Sewing machine head tilt detected during power-on. | Turn off power. Lift the machine head back to vertical. Check main board socket P14 . | | 51 | Machine head tilt detected during sewing. | Turn off power. Check main board socket P14 for proper connection. | | 55 | Machine head tilt detected during power-on. | Turn off power. Upright the machine head. Check main board socket P14 . | | 65 | Key stuck or contact failure on control panel during power-on. | Turn off power. Inspect the control panel keys for mechanical sticking or debris. | | 100 | "GREASEUP" notification ignored (machine requires lubrication). | Add grease immediately. Perform the "clear work" or reset operation as described in your manual. | | 111 | Incorrect stopping position. | Turn off power. Check for abnormalities in the thread trimmer device or the sewing machine motor/sensor alignment. | | 121 | Trimming cannot be completed. | Turn off power. Check the fixed knife and movable knife blades for scratches, damage, or dullness. | | 130 | Main motor failure. | Main spindle motor or motor controller is faulty. This usually requires professional service . | | 131 | Synchronizer poor contact. | Turn off power. Inspect the motor main board socket P11 for a secure connection. | | 132 | Abnormal rotation of the main motor. | Turn off power. Check motor main board socket P11 connection. | | 133 | Main motor stop position failure. | Turn off power. Check motor main board socket P11 connection. | | 150 | Main motor abnormal temperature rise / sensor failure. | Turn off power. Check the motor condition. Note: This often occurs after repeatedly sewing very short stitch cycles (e.g., 15 stitches or less), causing the motor to overheat. | | 200 | X-direction origin not found. | X motor failure, or Y origin sensor failure. Professional repair likely needed . | | 201 | X pulse motor abnormal stop. | Turn off power. Check for physical obstruction or mechanical issues in the X fabric feeding direction. | | 203 | X motor over-current. | X motor failure, or X motor control board failure. | | 204 | X pulse motor abnormal stop during sewing. | Turn off power. Check for issues in the X fabric feeding direction (e.g., debris, binding). | | 205 | X pulse motor abnormal stop during movement to sewing start position. | Turn off power. Check the X fabric feeding direction for abnormalities. | | 206 | X pulse motor abnormal stop during inspection/transfer process. | Turn off power. Check the X fabric feeding direction for issues. | | 207 | X origin cannot be detected. | X origin sensor or motor feedback failure. |
The Siruba L818FM1 is a widely used industrial sewing machine; when it throws error codes or behaves unexpectedly, knowing quick diagnostics and fixes saves downtime. Below is a practical guide covering likely error types, probable causes, step-by-step checks, and recommended fixes and preventive measures. siruba l818fm1 error list work
1. Turn off power.2. Unplug and check pins inside the panel connector wire.3. Firmly reseat the data connection plug. Controller Overheating
Check if the motor's safety switches are engaged or if a fuse has blown. : Adjust the presser foot pressure using the top knob.
A2: This intermittent problem, where the machine's behavior changes after a power cycle, is often a sign of a failing component on the main control board. The most reliable fix is replacing the control board . The machine failed to stop at the correct
If the head is flat but the error remains, the switch may be broken or misaligned.
80% of "E" errors are solved by cleaning lint (E-01, E-02) and reseating connectors (E-04, E-06). Only 20% require parts replacement. Always start simple.
