Hi, sorry I didn't get back to you sooner I have been having problems with my email.
the macnine is 5 years old. I have never had any problem with it previously. I was sewing with it then decided to change the cotton to do another job. I tried to wind the bobbin. it showed it winding on screen and then made the bleeps and then showed the ! sighn and stopped working.
Although it showed the bobbin winding it didn't even start to wind. I checked all the machine very thouroughly for dirt and cotton and then switched it on and off this suposed to cure it but it diddn't. it also said in the book the machine would be locked up if I got the ! message but it wasn't everything was free
