I was given my aunts Combi DX model 502, the past weekend. It is a combination sewing machine and serger machine. The bobbin thread is coming up through the fabric. I have been trying to get the tension to work, I have moved the tension knob higher and lower and nothing seems to work. What else can I do???
You have been answered in another post. I think that your machine is in desperate need of a good service. If you force it to work, you may have a very expensive repair. The $89.99 that you mentioned before is NOT to much to pay. A new machine is much more that that.
