Take it for service. It could be a simple problem but it probably isn't good for the motor to be activated constantly. Also, it could be a possible fire hazard.

Also, make sure the needles are brand new.

Another possibility is that some of the threads are not seated completely in the tension disks or the machine is not threaded correctly. When threading the machine, make sure the presser foot is ALWAYS RAISED so the tension disks are released. Also, be sure to give each thread an extra little tug when threading the tension disk. Sometimes, they will actually make a little popping noise when they seat.

Looking for Bernina overlocker 1100d manual

Unfortunately, BerninaUSA used to have a lot of out-of-print manuals available on their web site (under Support). However, it appears that just recently they eliminated a lot of the manuals including the Serger 1100 series manuals. You can find them for sale on the internet (try eBay or, or you can try downloading a similar model's manual from the Bernina web site:, select Support, then Out of Print Manuals.

Got bernina 1015 sport sewing machinewith one foot want to buy zip,buttonhole &overlock foot is ther a special number or do all bernina feet fit al types of bernina machines

This machine uses 'New style' snap on feet. The reason it is 'new' is because old style Bernina feet are the complete foot, whereas new style you just 'snap on' the foot base.

Ebay is the best place to find original Bernina feet at very reasonable prices. I recently purchased a solid steel 'old style' foot from UK for U.S. $28.

When purchasing zipper feet, decide if you want regular zipper foot or invisible zipper foot. Often it is cheaper to order both at the same time, due to S&H fees.
