washer dryer proplems indesit widl 126?

hello i have an indesit widl126 washer dryer. it has been having a few random problems over last few months: stopping in middle of was cycle, then recently it has been filling drum with water at end of drying cycle and now it just doesn't heat up during drying cycle so is not drying anything. have been advised it might be programmer but can find no info about a programmer. have you any ideas? i'd be ever so grateful!
