One also had the F15 fault on our Dyson CR02 flow check . A quick call to their office 0870 600 2701 and the engineer was at the door of our home the next day. You will never buy another machine, Dyson second to none, Dyson there is no other for after service. Worth every penny of purchase. I'll leave it at that. Yeovil, Somerset.
