I wonder if they sell parts to the end user. This is from one of the Ariston/Splendide manuals:
Spare Parts
This dryer is a complex machine. Repairing it yourself or having a non-authorized person try to repair it could cause
harm to one or more persons and to the machine, and could invalidate the spare parts warranty.
Call an authorized service center if you experience problems while using the machine.
