If your brushroller isn't spinning it will make the loud sound. Try removing the brushroll and reinstalling it. If this doesn't work, you may need a new brushroller.You can find one here...

SOURCE: 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.

Samsung vcu366 making loud noise but picks up


what does the really loud noise sound like? Is it a loud, whining sound? if so, the motor may be getting ready to go out. Also check that the belt isn't stuck-though you would smell burning rubber if that were the case.

My vacuum cleaner start up fine, then quickly


Hi There,

This is a telltale sign that your vacuum cleaner is clogged. When the motor makes the higher pitched louder noise, your motor is not able to pull air through it, and has to strain harder because it's not able to breath.

Because you have already narrowed it down, that the noise only happens when you put the wand back into the vacuum, this means that you clog is definitely in the bottom section of the vacuum cleaner. Most clogs on upright vacuum cleaner occur right at the suction port behind the roller brushes on the bottom of the machine. Turn the vacuum upside down so that the brushes are facing upwards. Unscrew the bottom plate of the machine so that you may access the roller brush and belt. Look behind the brush roller for the opening of the vacuum where the suction port it. Look inside here and see if you can visibly see anything lodged inside. Sometimes just pushing a long screw driver into this hole can dislodge the obstruction.

If you aren't able to see anything in this port, and the screw driver doesn't dislodge it, look inside the small section of how that the wand connects into, and try pushing your screw driver down this hose to see if you can dislodge it from this part.

Sometimes a metal hanger can also effectively unclog hoses on vacuum cleaners, but just be careful that the hanger doesn't tear the lower hose section while you're pushing it through.

Also if you have another vacuum in the home, using the hose from the other vacuum and putting it inside the lower hose, or the suction port behind the brushes while you're pushing with the screw driver will also many times dislodge the obstruction easier.

Please let me know if this was able to unclog the vacuum cleaner, and I'd be more then happy to try and do some more advanced diagnosing with you for your vacuum cleaner.

If this was helpful to you, please help other Fixya users find this repair by rating helpful. This is greatly appreciated, and is what keeps Fixya repair experts continue giving free advice on the site.

Thanks so much,

Doesnt ****


Hello,

If the vacuum sounds like it usually does and still doesn’t pick up, you probably need to replace the belt. To check this, turn the vacuum on and lay it down sideways. Check to see if the roller is spinning. If it's spinning, turn the vacuum off. Stand it up and turn it back on. Do you hear the roller spinning. Some belts stretch over time. If the roller was spinning when the vacuum was on it’s side and stops when the roller has some pressure on it (your carpet), change the belt.
A clogged vacuum cleaner usually sounds "clogged". The noise the vacuum normally makes will seem muffled. First, Unplug Your Vacuum. Then change the vacuum bag or empty the dirt cup. If the bag is filled up more than halfway, this could reduce your suction. Throw out the bag. Look at the area that holds the dirt cup or vacuum bag. Remove any debris. Look for a filter in this area. If you find a filter make sure it's relatively clean. A clogged filter will shorten the life span of your vacuum. Make sure your filter is back in place or replaced, and reinstall the vacuum bag or dirt cup.
A lot of the current style upright vacuum cleaners have attachments and a hose on board. If you have a vacuum hose on your upright, pull it out like your going to vacuum with it. Look at the area you removed the hose from. Remove any debris. I recommend wearing gloves, and try not to use any sharp tools like a needle nose pliers that might puncture your vacuum hose.
For the final step in this vacuum cleaner repair, place the vacuum in a position where you have a birds eye view of the bottom plate. You can usually see if there is any debris that requires removal.
Here is a link that will take you to a site that shows how to access your machine to change belt or look for clogs.

I have a kirby g4 vacuum that is 12 years old. it sounds like


About once a month as I have German Shep dogs and cuz of the hair I check all the hoses to make sure they are free of dust bunnies. I also take the bottom plate off the roller, turn the lever to losen the belt and take the roller off. Clean/cut all the strings, hair etc off the roller , check the belt for cracks and burns and replace if need be. Put the roller cover back on, and reconnect the belt.

Then on the side of the machine where the bag attaches, this also slides out to clean. Sometimes heavier items will get stuck in there so that dog hair and larger items cannot pass to the bag and it clogs. This will make your suction very low.

Also a good check inside the bag compartment and clean with the attachment hose if need be, helps a great deal with ordor and dust when turned on. Especially if you have dogs/dander and hair. Ive also put carpet fresh inside my bag to keep the doggy ordor down.

Loud Noise


This sounds like something is caught in the brush roller. It is not uncommon for something like a pin, or nail or something of that nature to get caught in the roller chamber and when the roller spins, it will rub on the roller producing that sound. Sort of like putting a playing card in the spokes of your bike when you were a kid. Take the bottom plate off and remove the roller. Inspect the area around the roller for any foreign objects. While your there, check the belt for wear and tension and also check the roller bearings for any material that would interfere with it's smooth rotation. You should also check the hose intake for blockage.

Vacuum Roller making a loud noise


Your roller brush is starting to fail. If you unscrew the ends, you will find a lot of hair wound around the stem. You probably have a warped plastic end the holds the bearing. This is my problem now.... I am looking for a new roller brush as I write this. I found one for $30. Good Luck.
