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.
Always utilize high-quality, water-clear industrial sewing oil. Yellowed or contaminated oil thickens over time, increasing mechanical friction, raising power draw, and triggering critical E15 overcurrent codes .
If errors persist after troubleshooting, refer to a qualified technician for further electronic repairs.
If your machine is not producing stitches or is experiencing physical failures, check these common manual adjustments: siruba l818fm1 error list work
Inspect solenoid wiring under the machine bed for pinch points. Safety Switch Active The machine head is tilted back onto its safety rest.
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
When the electronic control system detects abnormal operating conditions, it immediately halts operation and flashes an alphanumeric error code on the control display. The table below lists the most common errors encountered during industrial production shifts, what they mean, and the exact steps required to resolve them.

: The control panel has lost tracking of whether the needle bar is up or down. The machine halts sewing operations to prevent breaking the needle or damaging the needle plate. Step-by-Step Fix : Power off the system completely.
1. Shut off the system power supply.2. Inspect the motor encoder connection cable for fraying, pin damage, or disconnection.3. Clean out accumulated fabric dust from the connector.4. Reconnect and restart. If error persists, the encoder board or motor requires replacement. Power Module Abnormal Overcurrent Safety Switch Active The machine head is tilted
The motor is trying to turn but cannot. This is often a mechanical blockage rather than an electrical one. 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
Thread clumping (bird-nesting) or the "E2" error (common on some generic boxes).
