I have the same machine. I took it to be cleaned and they did not do it. Listed things they were suppose to have done, just to make money off of me. I won't go back, never liked any of them for years, no one else in the area. Since then I have someone to take my machines to. I have not had that machine cleaned. I sew for hours at a time on the weekends, only about 3 hours or so each evening. Clean visible areas and oil it. When they quit working I will have them serviced. I have three back up machines.
