Repair a Dyson V11 Absolute soft brush head?

Mine has stopped working. Took it apart and there's nothing jamming it. The motor spindle turns freely. Just over 3 years old. Not high usage.

Checked for continuity across the terminals - nothing. Checked continuity on another good head and and it bleeps continuity for about 3 seconds, then reverse the tester leads and get another 3 second bleep - some capacitance going on there.

A new head will cost around £80.

Anyone tried fixing one of these - can you buy the motors?

Tanks.

Well, it turns out I was able to mend it. I had a good look at the construction and saw that it had quite a few screws, mostly torx head, so I though I'd at least try taking it apart.

As soon as I removed the end plate, which users can do to remove the roller and unclog it, a piece of curved plastic fell out. At that point I could see that the motor is a long cylindrical thing, held in place with a large screw through one end, that sits inside the roller.

I could see that the piece of plastic had come off a sort of circular collar that sits between the motor and the side that it was screwed to. I undid the motor retaining screw and the motor just fell out - the two wires supplying power to it had been neatly sheared off.

It seems a jam must have caused the collar and motor to rotate, shearing the wires. The collar has a small slot that fits around a locating 'spud' to lock it in place but when the roller jammed, the force of the motor was too much for it and it just tore the plastic off.

I reconnected the wires, using a small extension to each to make it easier, put it back together and added a small screw through the collar to lock it in place, then epoxied the broken off plastic piece back again for good measure (although the screw will take the strain in future and will be stronger than the slot/spud arrangement).

Saved me £80.

I presume the motor must have some sort of internal clutch so this shouldn't have happened - jams are a fact of life for vacuums surely?
