The best way to "work" on error lists is to never see them. Follow these maintenance schedules:
| Time Interval | Action | Errors Prevented | |---------------|--------|------------------| | Daily | Remove lint from hook area and fan inlet | E-05 (overheat) | | Weekly | Clean pedal optocoupler with compressed air | E-04 (pedal error) | | Monthly | Check all cable connectors (CN1 to CN10) | E-06, E-02 | | Every 6 months | Update firmware | E-10 (corruption) | | Annually | Replace main capacitor in control box | E-03 (voltage ripple) |
Sometimes, the machine behaves like it has an error, but it's a misconfiguration. Here are parameters that work like errors:
To reset all parameters to factory defaults:
Note: exact codes and meanings vary by control module version. Always check your machine’s service manual for definitive code definitions.
(If your unit shows other codes, treat them as controller-specified — power-cycle first, then consult manual.)
Missing from the official list but common in forums:

If you’re a home sewer: this error list will scare you at first, but each code has a simple fix (clean, reset, reboot).
If you’re a small factory owner: the error list saves troubleshooting time – you’ll love E-02 preventing blown motors.
Final score: 8/10
Deducted 2 points because the manual lists errors like a robot wrote it, and the machine refuses to sew when E-01 appears – even if you’re sure the pedal is fine. A “force override” mode would be gold.
But honestly? The Siruba L818F-M1 is one of the few machines where reading the error list feels like having a conversation with a grumpy but brilliant tailor. Respect it, and it’ll sew faster than you can feed fabric.
Would you like the actual numbered error list from the service manual in a clean table format too?
Siruba L818-FM1 is an industrial lockstitch sewing machine typically equipped with an electronic control system. If your machine displays an error code, it usually indicates a motor, sensor, or power supply issue.
Below is a consolidated list of error codes and troubleshooting steps based on Siruba electronic control standards. SiRUBA Sewing Machine Common Error Codes & Solutions Error Code Description Recommended Action High Load / Torque
Check if the machine is jammed or the material is too thick. Ensure the motor is not overloaded. Over Voltage / Inertia The best way to "work" on error lists is to never see them
Check the power supply voltage. If the machine inertia is too high, you may need to lengthen the deceleration time in settings. Motor / Machine Locked
The motor cannot turn. Check for mechanical jams in the handwheel, hook, or needle bar. Ensure the motor connector is securely inserted. Motor Signal Error
Check the motor connector pins and wiring. Ensure no "extraordinary" or noise-heavy signals are interfering with the input. Needle Position Error
The synchronizer cannot find the needle position. Check the needle positioner (synchronizer) on the handwheel. Ensure the cable is plugged in. Position Detector Error
Check if the detector (synchronizer) connector is loose. Verify if the UP/DOWN signal is broken. Solenoid Fault
A short circuit in the solenoid wiring or a defective solenoid coil. Inspect the trimmer or back-tack solenoid. 12V Power Failure
Check the internal fuse for the +12V power supply on the control board. Encoder Signal Error Sometimes, the machine behaves like it has an
Turn off power and check the motor encoder connector. It may be loose or have fallen off. Restart the system after securing it. Over-Current Protection
Power module abnormality. Turn the machine off for a few minutes and restart. If persistent, the power board may need repair. Safety Switch Error
The machine head may be tilted back or the safety switch is damaged/misaligned. Ensure the machine head is properly seated in the table. General Troubleshooting Steps
: Most electronic errors (like E15 or E2) can be cleared by turning off the power for 30 seconds and restarting. Check Connections
: Ensure all cables from the motor to the control box and from the synchronizer to the motor are tight. Mechanical Check
: Manually turn the handwheel to ensure the machine is not physically jammed. Voltage Check
: Ensure your local power supply matches the motor nameplate requirements.
