	Error Code E7 The motor has locked. (The motor fails to rotate) Check whether the sewing machine head has locked. (Is it possible to turn the pulley lightly by hand?) Check whether the tread has been tangled in the pulley of the sewing machine. Check whether the thread has been tangled in the motor pulley shaft. Check whether the thread has been caught in the hook. Check whether the proper amount of oil is supplied to the hook. My guess is your hook and cutter are stuffed with thread and thread dust. Remove the cover plate (2 screws) and the feed dog (2 screws) and carefully clean the junk out. You also likely have thread wrapped around the shaft behind the bobbin assembly. Use a seam ripper to get that thread out. REMEMBER TO UNPLUG THE MACHINE BEFORE YOU CHECK ANY OF THESE ISSUES!! You could try going to www.fixya.com __________________ CARPE CRUSTULORUM!

	Hi, A technician had a look at it, he believed it is one of the electronic board that suppose to supply a high voltage to the motor , that had failed and it is very expensive to replace. He was quite generous, he did not charge me for the troubleshoot. I had look myself afterwards, and there are 4 larger circuit boards and a few small ones so not sure which one is the high volt one. Any advice.

	Before you toss out the machine or pay too much money to have it repaired take a close look at the areas suggested above. Believe it or not some "technicians" will not tell you the whole truth just to get your cash. He may come in and clear out a jam or tangle of thread then charge you for a new circuit board. If you decide to throw it away and replace it send it to me, I can always make use of another one Good luck. __________________ CARPE CRUSTULORUM!
