Ariston Margherita 2000 is a generic for a range of machines, the specific model number would be a help - right lower corner of control panel ie A14..
Most of these machines have a removable cross piece on the rear of the tub. If it's aluminium, there is a bearing kit available. If it's cast iron, you're supposed to replace the cross piece. Expensive.
The bad news bit is that the stainless tank is a sealed unit. If the drum support has broken an arm, you will need to replace the whole sheebang.
Or, as you have suspected, the whole machine............ :roll:
Luck and regards,
Which bit of "Unplug it" is causing the problem?
