This is a copy of the post on your premium solution thread.
According to Singer guidelines , if there is only red blinking light,
then there is an fault inside the machine, unless it reset
disconnecting from power.
If there is an error code with format EM-01 - EM-09 tell me which error you get and I should find a fix.
Here is a complete user guide, check pages 90-92 for common errors.
If you have no error message, and light does not go out with power disconnect then it may be a faulty control board.
In this case I suggest doing a last attempt removing all threads, and reset design unplug from power 10/15 mins.
Let me know if you still have the problem.
Regards
