We always offer the dead parts to the user and I am delighted for them to go back in somebody elses bin ::)
In the case of warranty claims, the parts go back to the importer- and usually then to the manufacturer.
As for what the appliance companies do, dunno, dun care....
As far as Im concerned, if youre paying, you can do what you like with the bits. If were paying, we repair the machine and you take it ;)
I am sure that all CS sponsors act with a whole heap more integrity than dodgy bros. inc. *;D
