I had this too with a embrodery machine. 5700 I think. I broguht it in they did nothing about it and charged me $100 for cleaning a near new machine that I did not bring in to be cleaned. DG went in there and cut some thing down. Now about 6 yrs later the machine bleongs to my DD and the foot totally died. DH bought a replacement off the internet but got a pedal that also fits the 6500. I new it would fit bcause DD had been borrowing mine for a bout 1/2 yr. I have never had a problemw tih the 65oo pedal. Obviously it is a deffect but they did not replace or fix my pedal when I went in. Good luck! If you want I can ask DH where he ordered it. It was way less.
