| Error Code | Meaning | Likely Cause & Solution | | :--- | :--- | :--- | | | Machine head locked / overload | Thread tangled in hook, foreign object in rotary hook, or mechanical seizure. Turn off power, clean hook area, and check for free rotation. | | E-02 | Motor position signal error | Faulty synchronizer or encoder. Check the position sensor near the handwheel. | | E-03 | Overvoltage (power supply) | AC input voltage too high. Use a voltage regulator. | | E-04 | Undervoltage | AC input voltage too low. Check power source and cables. | | E-05 | Overcurrent | Motor short circuit or driver board failure. Stop immediately; service required. | | E-06 | Motor overspeed | Control board failure. Turn off machine, restart. If persists, replace control box. | | E-07 | EEPROM (memory) error | Settings corrupted. Reset to factory defaults via panel (see manual). | | E-08 | Communication error (panel to control box) | Loose flat cable between panel and main box. Reconnect securely. | | E-09 | Needle up/down position not found | Magnet on handwheel missing or sensor faulty. | | E-10 | Presser foot lift motor error (if equipped) | Foot lift solenoid stuck or jammed. | | E-11 | Thread trimmer solenoid error | Trimmer stuck or solenoid coil open circuit. | | E-12 | Winding stop sensor error | Bobbin winder mechanism faulty or sensor disconnected. |

| Error Code | DIY Possible? | Tools Needed | |------------|--------------|---------------| | E-001, E-007, E-018, E-030 | Yes | Allen keys, brush, oil, multimeter | | E-005, E-040, E-099 | No (PCB level) | Oscilloscope, soldering station | | E-012, E-015, E-021 | Yes if electrical knowledge | Voltage stabilizer, screwdriver |

Confirm the reset, power down the machine, wait 10 seconds, and turn it back on. Preventive Maintenance Checklist Target Component Clean out lint and dust buildup Feed dogs, needle plate, and bobbin area Daily Check oil window indicators Main oil reservoir level Weekly Wipe external sensors and handwheel Synchronizer / encoder housing Monthly Inspect electrical cords and plugs Power connections and solenoid harnesses

: Ensure all connectors on the back of the control box are seated firmly. Electronic control parameter manual - SiRUBA Sewing Machine siruba+l818fm1+error+list+2021

In 2021, Siruba released a firmware update (v2.1.4) for the L818FM1 series, which introduced new error codes related to the digital tension control system and the servo motor encoder. While earlier models had simpler codes (e.g., Er01, Er02), the 2021 version includes more granular warnings for preventative maintenance. Therefore, if you own a machine manufactured or upgraded in 2021, this list is specifically tailored to your control panel’s logic.

) are workhorses, but electronic control boxes can sometimes stall your production with cryptic error codes. If your panel is flickering a code, use this quick-reference guide based on 2021 technical documentation to get back to sewing. Common Siruba Error Codes & Fixes

If the machine is functioning poorly but not showing a specific error code, the problem may be related to the direct-drive system setup. | Error Code | Meaning | Likely Cause

: Typically indicates a blown fuse for the +12V power supply. E14 : Specifically points to an encoder signal error. Quick Reset Steps

Clear the memory of the machine and re-synchronize the needle position if necessary. E8 - Position Detector Error

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 Check the position sensor near the handwheel

Which is currently flashing on your panel?

: The needle is not aligned properly after a jam, or there is a position detector error.
