Note: Always turn off the machine before conducting maintenance to ensure safety.
Turn off the machine and let it cool down for at least 15-20 minutes. Check for overheating signs. [E005] Pedal/Sensor Malfunction:
Triggered when the machine or motor is physically locked. This may be caused by a bird's nest of thread or an object stuck in the motor pulley. E7 (Communication Error):
Check that all safety guards are in place and that the needle position switch is not engaged, then turn the main power back on. 4. Memory and Software Errors (ERR1, ERR8) siruba+l818fm1+error+list+2021
Motor inertia is too high, or the sewing speed is unbalanced. Troubleshooting: Check if the power voltage is too high.
: A common error where the motor is physically locked or the sewing machine is jammed. Check for thread caught in the gears.
Clear the memory of the machine and re-synchronize the needle position if necessary. E8 - Position Detector Error Note: Always turn off the machine before conducting
The needle, trimmer, or feed mechanism has reached its limit switch unexpectedly. Check for mechanical jams. ROM/Memory Error
Below is a troubleshooting guide based on the 2021 error standards for the Siruba L818F-M1 series.
Hold down the (Program) or designated function key while turning on the main power switch. you are working with a single-needle
Check the position detector connector for loose wires. If the problem persists, the sensor may need replacement. E9 / ERR9 - Solenoid Defect / Short Circuit
Without access to specific data from 2021, I recommend checking:
Occurs when machine inertia is too high or the motor encoder signal is interrupted. Solutions include lengthening the deceleration time or checking the encoder connector. E3 (Motor/Machine Lock):
Based on the model number , you are working with a single-needle, flat-bed, lockstitch industrial sewing machine . This machine is part of Siruba’s heavy-duty direct-drive series, commonly used for medium to thick materials (jeans, bags, uniforms).
