This sounds exactly like what happened to me. It sounded like the bearing was going bad that would run the rod that spins the bobbin. couldn't locate it exactly. Turned out by going through it on the phone with a tech and he had me run about thirty drops of oil in the reservoir on the left side of the v-rail (don't remember what maintenance timer that on is) and after 5 minutes of soaking in the noise went away and had never returned. He explained that is why they changed the maintenance to reflect the extra oiling instead of the 9 or 10 we had been doing. Don't get me wrong we do our requested maintenance diligently but this still happened. So a little extra oil couldn't hurt. By the way, after the machine sat overnight or even a few hours the sound would go away or at least die way down, which even confused us more. until we realized that the oil that was there had a chance to lubricate the now non moving parts. Techs are great!!! Try it and let us know.

On mine, it turned out the nuts that hold the arms that hold the hoops were loose. I hope yours is as quick and easy! Judy
