A wide belt that failed due to dust would be out of character for Butferring. They had a series they got from Taiwan, not sure if they still do.
I find most Euro companies are either really good about warranty, or terrible.
Felder for example replaced a switch on my RL-160 3 or 4 years after I bought it. Martin only makes their planer with fancy electronics.. I would be shocked if there where a bunch of dead ones out there with failed electronics .. Martin seems to be like Felder, they're still interested after the cheque clears..
