Hi, thanks for that information.
Make sure the foot pedal is securely in place.
If it is, unfortunately you will need to bring your machine to any local sewing machine repair shot as there would be a problem on the main board with an electronic component.
Many local vacuum repair shops also fix sewing machines ;-)
I wish I had better news for you, I really do.
One other thing you can try, is to unplug your machine for 1 full hour, it May reset.
In any case, I will stick with you until this is complete please rate my service kindly.
Also it is the only way I am credited for my time and expertise with you.
Once you rate, I will be notified and will add your question to my priority list so you can reach me anytime until this problem is solved.
Then you can reach me by simply replying to this message anytime.
Thank you and have a Wonderful day!
No additional cost to rate kind;-)
