Having trouble with the tension and breaking thread

Had the same problem here. Took it apart and found that several tracks in the ribbon cable from the keypad to the circuit board on which the LCD display is mounted were broken hence keypad needs to be replaced. Its part number is XA4331002 and available online from Sewing World. Have just finished fitting the replacement and keypad and sewing machine are working A1 OK.

I think White sewing machines are part of the Singer group.
There is a free manual download available for the W955 (the W is for White) on the Sinnger website.
