It's new - a Janome 7025 that I bought in John Lewis about 4 months ago. I've used it a fair amount, never done any maintenance of any sort and it makes a huge racket when I sew. Always has done. I assumed it was normal until I went to a friend's house yesterday and saw her using her one which was almost entirely silent. It was a computerised John Lewis model (but made by Janome, I think).
What do you reckon? Should I haul it back to John Lewis to be checked out, or is it normal? If it is a problem, I'd like to fix it because I can't use it when dh is trying to watch tv in the evening because he can't hear anything over the noise.
