how to fix my servis m3022/m washing machine?

The belt has snapped but im worried that the machine does not drain or fill anymore. I cant see that the belt going would affect the drain pump or the fill pump and surely the motor would still turn, just not spinning the drum. The belt had wrapped itself around the motor though probably preventing it from spining. Im wondering if there is a reset button or something im missing. Basically im worried that if i get a new belt it still wont work. Help please!!
