This repair was on a base model DC07 without the brush bar control. I will include a guide on a model with a brush bar as soon as i can.
With the exception of the solepale and brushbar removal both repairs are very similar and shouldnt pose too much of a challenge to technical minded people.

First job is to remove side filter

This filter is in two parts both are washable and may be blocked and quite dirty. Please allow at least 24 hours to dry fully.

The dust bin should now be removed from the body of the vacuum.

With the bin removed this screw needs unscrewing

With the screw removed the switch case needs unclipping from the vacuum, this sometimes requires a screwdriver blade for a little leverage but dont damage the trim.

Now disconnect the cable from the switch and the unclip the blue cable spades

Now unlatch the wand from the vacuum body

Push this little plasic button at the base of the vacuum, it is holding the hose cuff onto the machine.

Pull the hose cuff up and it should come away from the vacuum complete with the wand and hose.

Remove inspection tube at the base with the latch clip

Now remove this inspection elbow

Now pull out the cable from behind the switch housing and remove from the long cable groove running down the back of the vacuum.

This is where the cable enters the motor part of the vacuum

Now the baseplate need removing. To do this please use a large flat blade screwdriver on the yellow retainers, they turn a quarter turn.

The baseplate has been removed and the brushbar and belt are now visible
The belt needs unhooking off the motor shaft this can usually be done without any tools

With the belt off the motor shaft the brush bar and belt can now be removed

Next task is to remove the small suction hose by pulling it off its flange

And here it is unclipped

The cradle on the soleplate now needs unclipping on both sides and requires a bit of effort to unclip sometimes.

Two retainers that keep the soleplate attached to the vacuum now need unclipping, a screwdriver helps here.

The soleplate now can be removed from the vacuum by bending slightly at either side and sliding the soleplate off the vacuum

Here is the other side

Soleplate removed.

Now four screws need removing (T15) red circles show where they are inside the tubes.

Here are the other two

Now with the screws removed, the motor case can be lifted out

Pull the cable out through the body and you should have this

Unclip the filter lid, a screwdriver may help but is very likely to damage the lid.

Remove this cover

Now unclip the motor retainer carefully with a screwdriver.
It is held with four lugs and requires a steady hand

Motor retainer off and the rubber motor mount can now be seen

Now the motor has to be pushed out. This will require some effort and may even need a little help with soft blow hammer against the shaft. Please remember that hitting the shaft with metal hammer will damage it and unless you are replacing the motor for sure it should be avoided.

The motor has been removed.

Here it is complete with top and bottom mounts

Remove top mount(s) and transfer to new motor

Again remove lower mount and fit to new motor

Disconnect the two wires off the old motor and reconnect to new motor

This is now the trickiest part of the job (IMHO)
The top motor mount has to allign perfectly to the shape of the housing, it can be quite frustrating to get it right as the fitting is tight and tends to move out of place as the motor is travelling up the case.
It may go right first time, but this is the exception and i once spent about an hour just trying to get this correct
The requirement here is patience as the wires can sometimes come unclipped as well and this means removal again!
It can be done just take your time.

Once positioned ensure the cable grommit is pulled taut from the machine as in the red circle

Refit motor retainer, its marked "top" for reference

You should now have something like this

Refit this piece of trim ensuring its not snagging anywhere

Thread the cable through this slot on the vacuum base

Refit the four screws again ensuring there are no gaps or snags

Refit the cable at the back of the vacuum to its groove, it should be quite easy to tell where it fitted.

Top of the cable goes through here into the back of the switch housing

Refit wires to switch and wire terminal, unsure everything is clear of the screw mount and sides and tucked away etc

Refit switch housing and it should clip with a bit of effort. However if the switch cables are fouling it and preventing it from clipping remove and inspect wires again.

Screw it up.
Its at this stage some people test the motor, but pleased be aware that the shaft is exposed and if it touches anything or anyone it will cause serious injury/damage so please dont do it

Refit the soleplate

Refit soleplate retainers

It should look like this now

Refit the lower suction hose to it flange, check its fitted correctly

Refit cradle and clip onto soleplate

Refit brushbar and belt, push belt through this hole here

And pull onto the motor shaft.

Ensure the brushbar has located in the lugs correctly (red circle)

Refit baseplate ensuring it is snug along all edges with no gaps

Filter lid snaps in place

Nice clean and dry filter goes back into its housing

And clips into place

Now to refit the back suction hose.
This lug in the red circle

Goes into this part (red circle)

It slides down and clips in place, ensure its fitted correctly

Refit the inspection tubes

And again refit the inspection tubes

Clip the dust bin in place

It should now run like new!
Please remember to PAT test your appliance after repair and if in any doubt get a professional to do it.
