Siruba L818fm1 Error List Work May 2026

Before diving into the error list, you must understand how the machine communicates. The L818F-M1 uses a digital display showing:

Pro Tip: If the machine beeps continuously or refuses to start, immediately check the display. Never force the handwheel—it can burn out the direct-drive motor.

Missing from the official list but common in forums:

Working with industrial machines like the Siruba L818F-M1 requires a quick understanding of its digital language. When your production stops and a code flashes on the LCD panel, knowing how to interpret it can save hours of downtime.

Below is a guide to the most common error codes and troubleshooting steps for the Siruba L818F-M1 series. Common Error Codes & Fixes

Most "ERR" or "E" codes on Siruba machines point toward power issues or mechanical obstructions. Error Code Potential Meaning Recommended Action ERR1 Pattern Read Error

Ensure the pattern is correctly selected or re-upload if using memory. ERR3 Needle Position Error

Check for a jammed needle bar or misaligned position sensor. ERR15 Motor Type Error siruba l818fm1 error list work

The control box cannot detect the motor type. Verify all cables are securely plugged in. ERR17 Emergency Stop

The emergency switch was triggered. Check the switch position to reset. ERR19 / 20 Voltage Irregularity

Voltage is too high (19) or too low (20). Check your power supply stability. E1 / E2 Overvoltage / Inertia

Often caused by the machine stopping too suddenly or power surges. E3 Motor Lock

The sewing machine or motor is physically jammed. Check for thread nests in the hook area. E8 Detector Signal

The machine has lost track of the needle's "Up/Down" position. Check the detector cable. Mechanical Troubleshooting

Sometimes the machine won't throw a code but still won't "work" correctly. In these cases, focus on these mechanical fundamentals: Solution:

Thread Breakage: Often caused by incorrect tension, poor quality thread, or a burred needle. Always ensure the thread is seated deeply between the tension discs.

Skipped Stitches: This is almost always a needle issue. Replace the needle regularly (every 8 hours of heavy use) and ensure the flat side faces the back when inserting.

Machine Not Starting: If the panel is on but nothing happens, ensure the safety switch (often near the tilt hinge) is disengaged and the foot pedal is properly connected. Pro Maintenance Tips

The "Reboot" Rule: For many minor electronic glitches, turning the machine off, waiting 30 seconds, and turning it back on can clear the temporary error buffer. Lint Control:

Build-up under the needle plate and in the bobbin case is the #1 cause of "E3" motor lock errors. Clean these areas daily.

Consult the Manuals: For specific part numbers or advanced parameter settings, you can find the official Instruction Books and Electronic Parameter Manuals directly on the Siruba/Kaulin website.
