This brochure talks about a 2 yr. warranty for commercial users with the possibility of an extension to 5 years by subscribing a professional service scheme (I don't know that that means). It doesn't address the warranty for a home user. I think I would contact the company & get something in writing if your paperwork doesn't indicate what type of warranty it has.
