Hi there, it's Jack at Dyson.
Our aim throughout the recent voluntary recall has been to retrieve, fix, clean and return all affected AM04 and AM05 heaters. This is free of charge to affected Dyson owners. Our engineers have developed a fix, and we're also reissuing the 2-year warranty as a mark of our confidence in our technology.
If you have additional concerns you're welcome to get in touch: http://www.dysonrecall.com
