How to fix error ER0. 4 on Siruba C007K Sewing Machine?
- HharrisondanielleAug 3, 2025
Error ER0. 4 on your Siruba Sewing Machine indicates a high voltage issue. Check the AC power supply. If the control box is an AC 220V system, do not use AC 380V power, as this will cause the error. Continuing to supply 380V power can damage the electrolytic capacitors (C3, C4) on the main board and cause the fuses (F1, F2) to open.
