No spin dry on Ariston model AL 1250 CT

Hi, really appreciate if anyone could help me out.
The machine works fine excepting spin dry only.
I had previously had problems with melted solder connections on the "REMCO" circuit board relay assembly, which gave me the identical problem to I have now, but I was able to solve it simply by running some solder over the melted sections.
Unfortunately it doesn't appear to be so simple this time though I am still very suspicious of this unit seeing that it has over heated before, but to test it I'd need more basic information;- does anyone have wiring diagrams or even better any ideas as to what this may be?
Thanking you for your time, regards Brian.
