The ‘fluffy’ direct drive head on our just out of guarantee Dyson DCv6 has just stopped working. The other motorised heads work file so I presume it’s not an issue with the main unit. I’ve had it apart, thoroughly cleaned it, checked the wiring to the motor in the head and even applied 5v DC to the pins where it connects to the main unit and sure enough the motor spins slowly.
There’s obviously something else going on as far as interaction between the motor and the main unit goes but I’ve no idea what to try next.
Any advice much appreciated
Thanks
SimonRe: Dyson DCv6 direct drive head failure
if as you say all other tools are ok you can assume the power socket is ok on the cleaner but is it ok on the tool head.
i dont think there is any logic circuitry involved but cant be certain as i have never seen one it too new

Re: Dyson DCv6 direct drive head failure
it seems to be as when I connect 5v DC to the two exposed pins the motor turns round. However when I pull the trigger to activate I don’t see the expected 16v across the pins which implies there is something going on.
Re: Dyson DCv6 direct drive head failure
There’s no circuitry in the head but there must be something in the body to cut power. I’ve had the whole thing apart, including the motor, there was a lot of fluff which I cleaned out and when I could get it to spin for maybe quarter of a turn (before cut out) I would see a puff of smoke.
Cleaning the brushes and around the coil assembly recovered lots of oily grime but yielded no results. I then connected a Dyson Battery directly to the motor and it span quickly, sparked and smoked a little but appeared to burn off any remaining muck.
The motor is now operating correctly again and I’ve reassembled the head.
Next time I’ll just try running directly with the battery to see if that resolves it without disassembly however there is obviously a risk there of burning out something permanently.
Hope this helps someone in the future
Cheers
Simon
