Below is the exhaustive error table for the Siruba L818FM1. Each entry includes the error code, display message, probable cause, and recommended solution.
| Error Code | Display Message | Probable Cause | Recommended Solution | |------------|----------------|----------------|----------------------| | E-001 | Motor Overload | Servo motor current exceeds 150% of rated value; fabric jamming under presser foot. | Remove fabric jam. Reset the machine. Check for thread entanglement in the hook area. | | E-005 | Encoder Signal Loss | Loose connection between motor encoder and main PCB (Printed Circuit Board). | Inspect encoder cable (CN7 connector). Re-seat the connector. Replace encoder if damaged. | | E-007 | Needle Up/Down Position Error | Needle positioning sensor (magnetic or photoelectric) is dirty or misaligned after 2021 firmware update. | Clean sensor area with compressed air. Run the “Needle Position Auto-Tuning” from the hidden service menu (Press and hold P + S for 5 sec). | | E-010 | Communication Error (Panel to CPU) | Loose ribbon cable between control panel and main control box. Common after vibration. | Turn off power. Remove and reattach the flat ribbon cable. Check for bent pins. | | E-012 | Low Voltage (Under-voltage) | AC input voltage drops below 180V. Brownout condition. | Use a voltage stabilizer. Check wall outlet (should be 200-240V). Do not share circuit with heavy machinery. | | E-015 | Over-voltage | AC input exceeds 260V or regenerative voltage from motor braking is too high. | Install a line reactor or surge protector. Check for faulty brake resistor (40-50 ohms). | | E-018 | Thread Trimmer Solenoid Jam | Solenoid for automatic thread trimmer fails to retract within 0.3 seconds. | Lubricate trimmer mechanism with silicone oil. Check solenoid coil resistance (should be 25-30 ohms). | | E-021 | Presser Foot Lift Solenoid Error | Presser foot lifter solenoid stuck or open circuit. | Manually lift presser foot to check mechanical binding. Test solenoid voltage (24VDC). Replace solenoid. | | E-030 | Digital Tension Motor Limit Error (2021 specific) | The tension control stepper motor over-rotated or hit a physical stop due to thread dust buildup. | Clean thread tension disks. Run “Tension Calibration” from panel: Parameter P-65->1, then confirm. | | E-033 | Main PCB Overheat | Internal temperature of control box exceeds 85°C (185°F). | Clean ventilation fan filter. Move machine away from heat source (steam iron stations). Allow 30 min cool down. | | E-040 | Synchronizer Signal Fault | Timing belt between upper shaft and synchronizer has slipped or broken. | Remove top cover. Check synchronizer belt tension. Replace belt (Part# SIR-818-BT). | | E-045 | Safety Switch Activated | Looper cover or front safety door is open while machine is running. | Close all safety covers. Check magnetic reed switch continuity. Bypass only for testing. | | E-050 | EEPROM Data Corruption | Factory settings lost due to electrical spike or firmware glitch. | Reset to factory defaults: Power off, then press and hold “RESET” + “S” while turning on. Re-enter all P-values. | | E-099 | General System Fault | Multiple conflicting errors. Often a dying main capacitor on the power board. | Call certified Siruba technician. Replace main filter capacitor (450V, 220µF). |
