Sorry about the problem but it's time to contact Babylock. If a repair person doesn't know where a piece goes then it's time to reach to a higher level. I have a Husqvarna (Viking). Am completely happy with this brand. Have had two in almost fifteen years. Bought a Babylock during that time but sold on e-bay because it just did not feel right. Very expensive to-boot. Have a spare machine I purchased from Nancy's Notions and that was inexpensive and steps above the Babylock. Plus I can go into my local quilting store, since that's where I bought the Husquvarna and get service and questions answered right away. Good luck with machine. Hate being without mine for any length of time.
