Hi-
I had the same problem with the needle plate, but I was getting an E4 error. Just got word from the shop it is ready to pick up- they had to replace the main board, which is the SECOND time this has happened- the first time it was in November and I was getting a F7 error message then. I really love working with this machine, but the little (and not so little!) problems are starting to get on my nerves!
