Open the rear panel and look for a broken or worn belt. If this is the problem you can replace it easily.
Good luck !

I have an Ariston Margherita AL128 and the same problem happened. After skimming through the manual, it occurred to me that it could be the pump that's causing not to drain or spin anymore. Dislodge the white covering infront (just located at the bottom). Once opened, unscrew the black button at the right hand side. Once open, check for blockages like coins, loose items, even lint. This worked for me and saved me $$$!!!! Now my Ariston is back to its superb performance. Do read the manual once in a while, it does help! I lost mine but was able to download a copy from the net.
