Re: Broken transmission strap
Luca,
If your Ariston is as bad as ours, then its more liekly that the drum bearings may have gone which may in turn have thrown the belt off. Either way, you maybe need to get a local engineer out to it.
If it is a front loader, then turn the drum by hand, it should feel smooth and turn freely, especially if the belt is off. If its a top loader, then shut the flaps and spin it by hand and the same should apply. If its noisy or “lumpy” when turned this way then its the bearings are gone and will not be cheap to repair.
