It is 30 years old that model so hardly worth the effort of fixing. Parts are no longer available from F&P. You could try doing a hot wash with very hot water. Even add a jug or two of boiling water. These machines had problems with soap build up through continuous cold water washes. This would stop them from spinning. Fill the machine let it agitate for 5 minutes. Stop it and let it soak for another 5 minutes then let it continue and finish the wash cycle. When it drains, advance it to the final spin and see if it worked.
