SOURCE: Brush roller won't turn
On my Dyson, there is a brush reset button on the top right hand side (if you are looking at the front) that you can press to reset the brush. I was vacuuming and too lazy to move a toy and this worked for me once I freed the rope from the brush.

SOURCE: roller does not turn
When a Dyson DC07 makes this horrible grinding noise, it can only mean one of three things.
The Dyson DC07 uprights use a clutch mechanism to control the brush spinning when you change the floor / carpet switch. When you hear this grinding noise, it's actually the clutch slipping because it can not spin the roller brush. 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's however will make that awful grinding noise rather then breaking the belt, and will only make that noise if the roller brush can not spin.
When you hear this noise on a Dyson, it can only be 1 of 3 things. Either your clutch mechanism itself has gone bad, or the roller brush itself was not properly put back into the vacuum, or the brush itself has gone bad.
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 belt 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 of how to test the brush:
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:
If the brush however was able to spin freely, and it spun multiple times, this indicates that most likely the brush was not put back in properly, or it could be a little more serious of problem in 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.
I think more likely however it's probably that the brush was not put back in properly, and this caused the brushes not to be able to spin, which would cause the clutch to make that horrible noise. Make sure that the roller brush is pictured like the brush above, you may also want to make sure that the bottom plate is put on correctly, this could also prevent the brush from spinning:
Here's a picture of the WRONG way to install the bottom plate. Notice the gap in between the two housings:
Here's another picture, that is the RIGHT way to install the soleplate:
If you need to replace the clutch, here's a direct link to the clutch your Dyson DC07 uses on our website:
Here's the video on how to replace the clutch:
When you hear that grinding noise, it can only be one of these three 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.
