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
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
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 siruba l818fm1 error list work
: Manually turn the handwheel to ensure the machine is not physically jammed. Voltage Check
: Ensure your local power supply matches the motor nameplate requirements.

The Siruba L818F-M1 is a high-speed, single-needle lockstitch machine known for its reliability. However, when the integrated motor or controller encounters a conflict, it will display an error code on the digital panel.
Understanding these codes is essential to minimize downtime and prevent unnecessary technician calls. Below is a comprehensive guide to troubleshooting the most common errors for this model. E1: Power Overvoltage
This occurs when the input voltage is higher than the machine's rated capacity (typically above 260V).
The Fix: Check your wall outlet with a multimeter. Use a voltage stabilizer if your local power grid is inconsistent. E2: Low Voltage
The machine is receiving insufficient power (usually below 180V).
The Fix: Ensure the machine is not sharing a circuit with other heavy machinery. Unplug the machine for 30 seconds and restart. E3: Motor Stalling (Locked Rotor)
The motor is trying to turn but cannot. This is often a mechanical blockage rather than an electrical one. The Fix: Check if thread is jammed in the hook or bobbin area. Turn the handwheel manually to feel for resistance. Ensure the belt tension (if applicable) isn't too tight. E4: Communication Error
The control box and the operation panel are not "talking" to each other.
The Fix: Check the data cable connecting the panel to the control box. Unplug it, check for bent pins, and firmly reseat the connection. E5: Overcurrent Protection Siruba L818-FM1 is an industrial lockstitch sewing machine
The motor is drawing too much amperage, often due to high friction or a short circuit.
The Fix: Lubricate the machine thoroughly. If the machine has been sitting idle, the oil may have gummed up the internal bearings. E7: Positioner (Encoder) Error The machine doesn't know where the needle is (up or down).
The Fix: Inspect the synchronizer/sensor located behind the handwheel. Ensure the plug is secure and that no dust or lint is blocking the optical sensor. E8: Brake Error
The electronic braking system failed to stop the motor at the designated time.
The Fix: This usually indicates a fault in the controller circuit board. Try a factory reset (refer to your specific sub-model manual for the key combination). Maintenance Tips to Prevent Errors
Clean Weekly: Remove the needle plate and blow out lint from the feed dogs.
Oil Levels: Ensure the oil pan is filled to the "High" mark with clear, stainless sewing oil.
Voltage: Always use a surge protector to shield the sensitive PCB from spikes.

Troubleshooting Siruba L818F-M1: Comprehensive Error Code & Maintenance Guide
Navigating the technical issues of industrial sewing machines can be challenging. For the Siruba L818F-M1 (and its variants like the L818F-BM1/DM1), keeping operations running smoothly requires understanding its specific digital signals and mechanical feedback. Common Siruba L818F-M1 Error Codes
Electronic control systems for Siruba lockstitch machines often display error codes to signal protection modes or component failures. Error Code Potential Cause Recommended Solution E05 Abnormal speed control unit connection Preventive maintenance (keeps errors away)
Check if the speed unit connector is loose or dirty. Restart the machine; if it persists, replace the speed control unit. E07 Motor locked rotor
Inspect the machine for thread jams in the hook area or check if the belt is too tight. E09 / E11 Positioning signal error
Ensure the encoder is properly connected and not loose. Clean the sensor disc if accessible. E14 Encoder signal error
Turn off the system and check the motor encoder connector. If the connection is secure but the error persists, the motor may need service. E15 Abnormal over-current
This is a power module protection. Check the main power board for signs of damage or short circuits. E17 Tip-over protection switch
Triggered when the machine head is tilted. Ensure the machine is in the correct upright position. ERR3 Needle bar position error
Often related to the synchronizer. Calibrate the needle stop position. Essential Troubleshooting Procedures
When your machine isn't functioning correctly but hasn't thrown a specific code, follow these standard diagnostic steps recommended in the Siruba L818F Instruction Manual: DL720 Series
This guide provides a comprehensive breakdown of the error codes, their causes, and troubleshooting steps for the Siruba L818FM1 sewing machine.
The Siruba L818FM1 is a high-speed, single-needle, lockstitch machine with an automatic thread trimmer. Its error system is designed to alert operators of mechanical jams, electrical faults, or parameter issues.
Sometimes, the display shows an obscure code like "Er-12" (not officially documented). Use this step-by-step diagnostic workflow:
E-12, Er07), share it with me and I'll try to interpret it based on known industrial sewing machine error patterns.However, without more specific context about what "error list work" entails, it's challenging to provide a detailed response. Generally, an error list or troubleshooting guide for a piece of equipment like the Siruba L818FM1 would include common issues, error codes, and steps to resolve or troubleshoot these problems.
