I have a windsor vsp 14, it is making a bad grinding noise, when I take the top blue piece off it stops, the brush works fine and when I put the top back on it grinds really loud and gets hot. it still vacuums and the belt and brush are working fine, can't figure it out. and when the lid is on I cant see what its grinding on. It only makes a grinding noise when you pull handle back and engade to vacuum flor and stops when you put it upright.

Probably from underneath

Could very well be the belt. When cleaning the brush it is a good idea to add some WD40 at the ends where the plastic pieces are that hold the brush in the vacuum. The brush needs to be able to move freely around the plastic pieces. Add the WD40 and rotate the plastic pieces around the brush until they move freely. Reassemble making sure the belt is put in correctly so the brush moves in the right direction.
Please provide a Thumbs Up if this solution is of help to you. Paul

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 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:

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.

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:



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.



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:



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 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.

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.

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.

this sounds like the motor went out

hello, have you checked to make sure you have nothing wraped around the brushes ? also it sounds like your belt needs to be replaced.

Mine did the same thing. I'm going to send it back for a warranty repair.
