Why does the lower thread break on my Bernina 790 Sewing Machine?
Lower thread breakage could be due to a damaged bobbin case, which would require replacement. Alternatively, the stitch hole in the stitch plate might be damaged, in which case you should contact the nearest specialized BERNINA dealer to have the damages repaired. A blunt or bent needle can also cause this issue, so replace the needle.
What to do if the display is inactive on my Bernina Sewing Machine?
If the display is inactive, it may be due to incorrect calibrating data. To resolve this, switch the machine off, then switch it back on while simultaneously pushing and holding the «Needle left/right» button to re-calibrate the display. Alternatively, the eco-function might be active; touch the «eco» icon to deactivate it.
Why is the sewing speed too low on my Bernina 790?
A low sewing speed can result from unfavorable room temperature; try placing the machine in a warm room one hour before use. It can also be due to settings in the Setup Program; adjust the sewing speed and the slide within the Setup Program.
What to do if stitch width is not adjustable on my Bernina Sewing Machine?
If the stitch width is not adjustable, it may be because the selected needle and stitch plate cannot be used in combination. Try replacing the needle and/or the stitch plate.
