I have the Janome 6600 as well, and have had to replace the fuses twice in the past six months. My machine however is 7 yrs young. The last time I sent it in for the fuse to be changed, I asked the serviceman to try and figure out why it kept blowing fuses. When I got it back, he said it was the automatic thread cutter jammimg because apparently I wasn't waiting for the machine to stop before I hit the cutter button. Now it works fine, I just make sure I slow down alittle (LOL). Anyway, since your machine is less than a year old, I would be a little concerned as to why you are getting the ERROR codes and blowing fuses. I know it is a pain not to have a backup, but, you need to know what is the cause for the fuse blowing. Ask your service guy to really check out your machine to see if it is out of whack. Warranty should cover any expenses at this point. Good Luck and I hope you get your machine back soon.
