Check the position detector connector for loose wires. If the problem persists, the sensor may need replacement. E9 / ERR9 - Solenoid Defect / Short Circuit
Check the under-bed thread trimmer mechanics to ensure nothing is jammed or mechanically binding. Reset the power to allow the machine to re-home. 4. ERR 10 - Counter Set to 0
The automatic presser foot lifter sensor or the auto-lifter solenoid is drawing unusual current, or the analog pedal sensor is uncalibrated. Resolution: siruba+l818fm1+error+list+2021
: Inspect the motor wiring for damage and ensure the sewing machine head moves freely without being "locked" by a thread jam. E2: High Voltage or Inertia
| 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. | Check the position detector connector for loose wires
Triggered when the machine or motor is physically locked. This may be caused by a bird's nest of thread or an object stuck in the motor pulley. E7 (Communication Error):
The safety switch detects that the machine head has been tilted backward onto its rest pin for servicing or oiling. Resolution: Reset the power to allow the machine to re-home
A large percentage of errors, especially regarding trimming (E007) or motor strain (E001), are caused by lint or broken thread caught in the bobbin area.
: For computerized models, errors can range from simple settings issues to more complex motherboard or sensor problems.
The is a high-performance, single-needle direct-drive lockstitch sewing machine frequently used in industrial garment production. Known for its efficiency, it features an integrated control panel that displays specific error codes (often in an "ER-XX" format) when issues occur.
If the machine is functioning poorly but not showing a specific error code, the problem may be related to the direct-drive system setup.
