I had my Brother 9 years before I had anyting done to it. It started acting funny with the emb. unit on it. I described the problem to the repairman, he knew right away what it was. he had it for about a week. His only comment was-you use this machine hard, you might want to bring it in a bit more often.
Really? between the kids and myself the poor thing never had a day off. Now it's just me and one DD so it does get a bit of rest.
