I've got a similar problem.
The machine turns on, you can select prgramme, but when the drum goes to turn it makes an awful grinding noise and the drum does not turn.
No error codes displayed either.
Also the drum hasn't been 'contra-rotating' for a while now, it used to select, made the oblivious clicking sounds but wouldn't fully engage. Now its just packed up completely.
This Dyson machine has been nothing but trouble; door locks, switches, computer panel, hinges... :(
