Remove the bottom cover plate and rotate the brush by hand. Look for things that make noise like stones caught in the brush path, bad brush bearings, bad drive belt.

Noise


Hi there, it's Jack at Dyson.
I'm sorry to hear you're having difficulty with your Dyson vacuum. From your description, it sounds like the model number you've supplied may not be correct, as DC08 is a cylinder vacuum which doesn't use a belt-driven brush bar. So we can confirm exactly which model you own and take you through some quick diagnostic checks, I'd encourage you to contact us directly. You can reach our experts by calling 0800 298 0298 (UK), or 1-866-693-9766 (US).
We'll look forward to hearing from you.
Best wishes,

DC07 grinding noise


I had the same problem with mine, I took it to a repair shop. The problem is where the belt passes through from the brush and goes inside the machine. Move the belt over a bit and you will see that a plastic guide has been bent over and is pressing onto the brush, which causes the noise. Just bend it straight again and it stops.

My Dyson Animal has good suction and works fine for actually picking up dirt, but when I use the vacuum with the roller, I hear a grinding/rumbling noise. Its only when I use the vacuum with the brush...


Trace the path of the suction into the tank and see if there is anything loose or ingested. Also, remove the brush and clean as best you can. Perhaps there is something caught in it. Lubricate where it makes sense with some WD40.

Roller does not turn


Hello,

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 vacuum2_bing.gif.

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:

b45ef25.jpg
Step 2. You see on the bottom of the vacuum 3 plastic screws that are usually the same color as the vacuum cleaner2_bing.gif. 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:
http://www.govacuum.com/dysondc07.html


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:
http://www.govacuum.com/dydcclasfore.html

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. 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.

Beaterbar will not turn and very loud grinding


Greetings,

When the Dyson DC07 makes that horrible grinding noise, there's really only one of two things that can be wrong. I have taken a few pictures to help you try and diagnosis the problem.

The grinding noise is made by the machines clutch mechanism. The clutch is what stops the roller brush from spinning when you change the vacuum from carpets to bare floors. The grinding noise is the clutch slipping, and not being to able to turn the belt. In most vacuums when the belt can not spin freely it will cause the belt to burn or to break. On Dyson's, the clutch mechanism prevents the belt from burning or breaking if you were to get something stuck in the brushes such as a towel underneath of a bad, or tassles on an oriental rug.

So when you hear this grinding noise, only two parts could be bad, the actual clutch mechanism itself, or the roller brush. I'll gladly help you diagnosis, and give you instructions on how to fix your Dyson.

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:


b45ef25.jpg
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 comletely, just a half of a turn is all), simply pull upwards on the bottom plate to remove it.


13bda0c.jpg
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 manuvering, 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:


9665ae3.jpg
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:


3a76171.jpg
If the roller brush went bad, then you'll need to purchase Genuine Dyson DC-07 Roller Brush for Models That Use a Clutch Part # 904174, then reinstall the new roller brush into the vacuum when you get it.

If the brush however was able to spin freely, and it span 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. I posted a 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 hope that this was able to at least diagnose the problem for you. That horrible grinding noise can only be one of those two problems.

When I tilt back handel and turn dial to carpet It makes a loud grinding noise


On a Dyson this engages the brush bar. Two possible faults: Debris (hair etc) caught in brush bar - cut out with knife. Or - damaged drive belt - pieces of belt striking casing. Last, but unlikely cause, debris in bearings of brush bar - replace brush bar.

My dyson is making a loud horrible noise


Hi.

Check the brush roller can be moved by hand & that it is not snagging on something.
If it is difficult to rotate remove sole plate by turning the 3 plastic screws to unlock position lift plate off & clean brush roller & check you can turn it after this.
If brush roller is free to rotate the chances are the clutch is faulty & will need to be replaced.
Go to this site http://dysonmanuals.llc.nu/
It has manuals that cover clutch replacing on all Dyson models.
