This troubleshooting guide details the complete , explains why each error occurs, and steps through how to resolve them to get your machine back to work. Siruba L818FM1 Error List & Fixes Error Code Issue Description Common Cause Quick Solution E01 / E02 Overvoltage / Power Surge High supply voltage or high machine inertia. Check wall outlet voltage; lengthen deceleration time. E03 Motor or Machine Locked Thread jammed in hook; mechanical binding. Clean the rotary hook; check for bound gears. E04 Communication / Signal Error Loose connection on the motor plug. Securely re-insert the motor control connector. E06 Signal Interference / Noise High-frequency outside electrical noise. Remove external noise sources; check shielding. E08 / E09 Needle Positioner / Signal Error Disconnected encoder or broken UP/DOWN signals. Tighten encoder; check synchronizer plug. E11 Solenoid / Fuse Defect Blown 12V fuse or short-circuited thread trimmer coil. Replace the solenoid valve or control box fuse. E14 Encoder Signal Failure Loose motor encoder plug or broken sensor. Check data cable; replace motor if sensor failed. E15 Overcurrent Protection Module overload or bound motor drive. Power down system, wait 10 seconds, and restart. E17 Safety Switch Triggered Machine head tilted back during operation. Lower the machine head fully; check safety switch. Step-by-Step Troubleshooting for Common Errors 1. Fixing Motor and Head Locks (E03)
Check if the machine is physically locked. Rotate the handwheel manually to ensure the mechanism moves freely. siruba l818fm1 error list work
