Hello,
When a Dyson DC07 roller brush does not spin, it can only be caused by one of two problems.
The Dyson DC07 uprights use a
clutch mechanism to control the brush spinning when you change the
floor / carpet switch. When the brush doesn't spin, it's caused either by the clutch or roller brush gone bad.
Most other uprights use a belt to spin the roller brush, and if
something is stuck in the roller brush it will cause the belt to break.
Dyson vacuums however will make that awful grinding noise rather then
breaking the belt.
I'll be happy to
walk you through step by step on how to diagnosis this problem and find
out which one of these two parts is bad on your vacuum.
Step 1.
Make sure the vacuum is unplugged. Then turn the vacuum upside down so
that the brushes are facing up. It's easiest if you put the head of the
vacuum
on top of a bench, or counter top. This is how the vacuum should look:
Step
2. You see on the bottom of the vacuum 3 plastic screws that are
usually
the same color as the vacuum cleaner. If you're vacuum is purple, the
screws
will also be purple. Use a flat head screwdriver, and turn each of the 3
screws
a half of a turn, counter clockwise to loosen then. After each screw has
been
turned (you don't need to remove the completely, just a half of a turn
is all),
simply pull upwards on the bottom plate to remove it. 
Step
3. You should now be able to see the roller brush exposed. You'll now
need
to remove the roller brush. This will take some patience, and some work
in order
to get this brush out of the vacuum. There is a special tool that has
been
designed to help you get the brush out easier. I would try getting the
brush out
first before buying this special tool. The easiest way is to use a flat
head
screw driver and pry the belt up while pulling up and out on the brush.
With
some patience and some maneuvering, you'll be able to get the brush out
of the
vacuum. Here's where you should put the flat head screw driver on the
brush:
Step 4. Once you get the brush out of the vacuum
cleaner, it's time to test it.
Use your finger tips to hold just the end caps on the very end of the
roller
brush. While holding just the end caps, use your thumbs to try and spin
the
roller brush. Does the brush spin freely? It should rotate completely
several
times on each spin. If the brush doesn't spin, or you feel some kind of
resistance to the brush spinning, then this indicates that your roller
brush has
gone bad. Here's a picture

If
the roller brush went bad, then you'll need to purchase a new one.
Here's a direct link to the roller brush your machine uses on our
website GoVacuum.com:

If
the brush however was able to spin
freely, and it spun multiple times on each spin, this indicates a little more
serious problem of the clutch itself has gone bad. The clutch
replacement repair
is a much longer, more challenging repair to do. There is a very helpful
video on
how to replace the clutch below so that you may follow step by step
instructions
on how to change it. It was really helpful for me the first time I did
this
repair.
If you need to replace the clutch, here's a direct link
to the clutch your Dyson DC07 uses on our website:

the video on how to replace the clutch:
When the brush stops spinning it can only
be one of these two problems. This clutch mechanism was so
problematic that Dyson removed it on the second series of the DC07
models. I hope that this repair was helpful in diagnosing your
problem. If you have any questions about the diagnosing, or the
clutch change, please feel free to use the Clarification Request form
here on the Fixya repair page. If this was helpful you, please be sure
