If you are running complex, pre-programmed patterns, ERR1 or ERR8 might appear.
Timeout between the display panel and the main control board. Check the connecting cables. Positioner Error
Turn the machine off, wait 30 seconds, and turn it back on. If the error continues, you may need to reset the control box parameters, which should only be done by a trained technician. 2021 Maintenance Tips for Siruba L818F
E3: Overvoltage ProtectionThis occurs when the input voltage is higher than the machine's rated capacity, often due to power surges or unstable electrical supply.Solution: Use a voltage stabilizer or regulator to ensure a consistent power flow to the machine.
Install a dedicated voltage stabilizer if your facility experiences frequent power fluctuations. E02 / Err-02: Undervoltage Protection
Errors usually indicate issues with the motor, position sensors, or the electronic control panel. Error Code Meaning / Potential Issue Troubleshooting Steps Pattern Read Error
Turn the power off, wait 60 seconds for the capacitors to discharge, and turn it back on.
| Code | Description | Probable Cause | Solution | | :--- | :--- | :--- | :--- | | | Thread Trim Solenoid Error | The thread trimmer is jammed, or the solenoid wire is broken/shorted. | 1. Check the thread trimmer mechanism for thread debris or mechanical jams. 2. Check the solenoid connection plug inside the machine head. 3. Measure the solenoid coil resistance; if open circuit, replace the solenoid. | | E06 | Needle Position Sensor Error | The machine cannot find the needle up/down position. | 1. Check the sensor located near the main shaft. 2. Clean the sensor eye (remove dust/lint). 3. Check the sensor cable for breaks. | | E07 | Pedal Sensor Error | The pedal signal is unstable or missing. | 1. Check the pedal cable connection. 2. The pedal potentiometer (variable resistor) may be worn out and needs replacement. | | E08 | Safety Device Error | Usually related to a safety switch being triggered. | 1. Ensure the belt cover or rear cover is closed properly (if equipped with a safety switch). |
To avoid triggering the ERR list, maintain the machine according to 2021 industrial guidelines:
If the error appears instantly upon powering up a cold machine, the internal circuit board or IPM module requires professional repair or replacement. E07 / Err-07: Communication Error
Turn off the machine and allow the control box to cool down for 15–20 minutes.
Inspect the power cord and wall socket for loose connections. [E004] Overheat Protection:
The feeding mechanism is stuck, overloaded, or exceeding its programmed limits.
