Unplug the machine.
With plenty of light, look to see where the part that moves would be stuck. Dirt, hair, grime, and dust get caught, causing just what you are describing. Without seeing it, I will guess a simple cleaning of this will address and deliver a solution. Hair that gets stuck in turning brushes can be pried away with a stiff brush (old toothbrush).

Makes a ratchetting noise due to hair caught in brush; cleaned the brush and replaced the brush cover but still makes noise. what is the problem?


You have to take it to a vacuum shop and have a new clutch put in. The DC-7 and DC-14 have a clutch that needs replacing usually every year to year and a half.

Screeching noise


Hello,

When a Dyson DC07 makes this horrible grinding noise, it can only mean one of two 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 vacuums however will make that awful grinding noise rather then breaking the belt.

When you hear this noise on a Dyson, it can only be 1 of 2 things. Either your clutch mechanism itself has gone bad, or the roller 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.com:
http://www.govacuum.com/dysondc07.html


If the brush however was able to spin freely, and it spun multiple times, 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:

Here's the video on how to replace the clutch:


When you hear that grinding noise, 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.

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.

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:

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.

I have a dyson dc07 with a malfuncitoning clutch diagnosed here on fixya. I've replaced the clutch and the grinding noise when the clutch is engaged for carpet and non rotating brush problem presists. This...


Greetings from GoVacuum,

If you have replaced the clutch already, then this can really only be one other problem, and that is the roller brush. If the roller brush's bearing have locked up, and the brush is no longer spinning, this is going to cause the clutch to make that horrible grinding noise, and a lot of people incorrectly think automatically that the clutch needs to be replaced.

Here's a very easy way that you can test the roller brush on your Dyson to see if it may have gone bad. In 10 years of fixing and selling vacuum cleaners, I have never seen such a cheap roller brush that's in the Dyson DC07 models with clutches, unfortunately this is notorious problem we see on this particular model.

Ok, so to test out the brush, make sure the vacuum is unplugged, and turn it upside down. Remove the 3 plastic screws on the bottom plate, and remove the bottom plate to expose the brush completely.

You may then simply pull upwards on the roller brush, and take the brush out of the belt that is wrapped around it. After the brush has been completely removed from the vacuum cleaner, hold the brush with only your pointer fingers in each hand, and only put your pointer fingers on the outside of the bearing caps on each side of the roller brush.

While holding only the bearing caps with your fingers, try to spin the brush with your thumbs. The brush should spin freely in your fingers, and you should get a good 5 or 6 rotations with each spin.

If the brush doesn't spin, then your roller brush has gone bad. Espcecially with home that have long haired pets, or females, the hair gets between the bearing cap and the bearing inside and causes the plastic caps that are covering the bearings to heat up, ultimately causing the bearing caps to melt, and finally the bearings sieze, and the brush will no longer spin freely which is why the clutch makes that awful noise.

Good news is that the roller brush is not as expensive or as difficult to replace as the clutch was. You may purchase the DC07 roller brush here;
Genuine Dyson DC-07 Roller Brush for Models That Use a Clutch Part # 904174-01

If your roller brush does spin, then I'm baffled as to what could be causing the clutch to make noise, but I'd like to try and help you figure this out.

Please send me an email to chris.jones@govacuum.com, or just request a clarification request here on Fixya, and I'd be more then happy to try and diagnosis this Dyson further for you.

My dyson dc14 has a strong burning smell


A DC 14 has two belts - one that connects the motor ourput to the clutch mechanism (the dial that lets you turn off the brush rotation completely is part of the clutch mechanism), and another that connects the clutch to the brush bar.
Unfortuneatley, the one that connects the motor to the clutch is hidden under a plastic cover so is very difficult to check.
With the machine running, and NOT in the upright position (i.e. as if you were vacuuming a floor), make sure the brush bar is actually rotating. If it isnt, you need to check both belts and the clutch. Due to the cover being held by three "Torx" screws, one of which is very difficult to get at, this isnt easy.

If the brush bar is rotating, then the burning is an indication the motor is about to fail. Motor replacement is possible depending how good your DIY skills are, and again you'll need "Torx" drivers to dismantle it. Website www.dysonmedic.com has some very good info.

My dyson D17 is making an incredibly loud noise, like grinding, when the bottom brush rotates.


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.

The rattly sound means the drive belt has snapped or the protective clutch has slipped. This needs repair by someone who knows how to repair Dysons officially. Sadly its the kind of model that can't be done by the owner.

Dc 14 no suction/noise


Hi,

The sound you can hear is the clutch slipping the machine is designed to do this if the brush roller is jammed or foriegn object obstructing brush roller.

Remove the sole plate by turning the 3 plastic screws to unlock pull off sole plate now look for anything that is stopping brush from easily turning. If nothing obviouse but roller hard to turn by hand remove the brush roller & check the bearings at either end of the roller if they are siezed up A new roller will sort this out.

If brush roller is turning freely then your problem will be warn out clutch this will need replacing.

Its A lot to explain so try this site it has clutch removing manual for Dc14. http://dysonmanuals.llc.nu/

Belt


Hi.

Your Dyson will probably have A clutch unit this engages the brush roller when you pull the handle back to vacuum.

Check the clutch control knob which is at the bottom left front side of machine looking from the front & rotates to drive position when handle is pulled back.

If it doesnt turn the knob by hand to drive.

If you still have no brush rotation after doing all this then either the clutch is faulty or the second belt which goes clutch to motor has snapped & will need replacing.

There are service manuals available for these repairs at this site
