Question about Dyson DC39 Multi floor canister vacuum cleaner

Open Question

The brush roller no longer stays on. I turn the vacuum on, the roller is spinning and then also immediately after it gets to full speed (seconds after starting) it stops spinning. I owned this for only a few months and during this time I used it regularly and it worked perfectly on all my floor surfaces. The brush roller performed well on all the carpeted surfaces and on the linoleum I used it without the roller on. The roller is clean and free from anything entangling it, the canister is clean. Do you have any suggestions. Thank you

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

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.

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 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:

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:

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.

    Why does blinking light come on and vacuum shuts off


    If this is happening right after you turn the vacuum on, you probably have a belt issue or a brush roller issue. I would start with checking your brush roller to see if it spins freely. If it spins real freely, your belt is probably broken. If it spins freely but with some resistance, you still might need to replace the belt. I just worked on one last week that had that problem and a new belt fixed it. Worse case scenario, you might have a bad sensor. That sensor looks for the brush to spin at a certain speed and if it does not sense the right speed, it shuts the vacuum down and the light flashes. Hope this helps!

    The belt for the maain vaccume broke off and now with the new belt the roller will not work.


    It sounds like your roller brush itself might be bad. Try holding the roller brush holding just the end caps with your finger tips, and spinning the roller. Does the roller spin freely? If no, this indicates that your roller brush's bearings have melted together. This is a common problem for Bissell vacuums, as they use cheaper plastic bearing caps. The roller brush is not covered under the warranty either.

    When this part goes bad, this causes the belt to break almost immediately. If you tried replacing the belt, and it broke immediately, your roller brush has gone bad.

    Here's a link to the Bissell LiftOff Revolution rollerbrush on our site;

    Eats belts immediately


    HI There,

    Usually when the belt breaks immediately, this indicates that your roller brush has gone bad and needs to be replaced. I have never seen the motor shaft being damaged and causing belts to break before. When the roller brush can't spin because it's bearings have worn out, the motor shaft continues to try and turn the belt, but since the belt can't spin the motor shaft at that point burns right through the belt.

    To make sure that it's your roller brush, remove the brush from the vacuum cleaner, and hold it using just your two pointer finger tips, holding just the bearings caps at the end of the bar, and not the bar itself.

    Try to spin the brush using your thumbs. Does the brush spin freely without resistance? It should spin completely around 3-4 times on each spin. If it doesn't spin, then your bar is bad.

    If the brush doesn spin, and it continues to break belts, this means that the belt is being installed incorrectly, and is being pinched by the roller brush. Pull the belt forwards after installing to make sure the brush spins freely.

    Hope this helped you,

    Vaccum not turning or sucking


    Hello,

    It definitely sounds like your belt is broken. If something gets vacuumed up into the brushes, and prevents the brushes from spinning, the motor will continue to try and spin the belt and the brush, but since the brushes can't spin, this will burn right through most belts.

    Especially since you mentioned a sock being sucked up, and the roller brush not spinning, this is a tell tale sign of your belt needing replacing.

    Here's what you'll need to complete this repair:

    - Phillips Head Screw Driver
    - Hoover Windtunnel Replacement Belt, Non-Self Propelled, Hoover Part # 38528033
    - Depending on how long the sock was stuck in the brush, you may need a new roller brush as well. The roller brush for your model is Hoover Part # 48414110. Here's a direct link for the roller brush for your vacuum on our website:
    http://www.govacuum.com/generic-hoover-windtunnel-tempo-fusion-upright-12-inch-replacement-roller-brush-hoover-part-number-4.html

    If you have the Hoover Tempo Widepath vacuum that you listed the repair under, then here's a direct link back to our website, govacuum dot com, to the exact belt for your Hoover Tempo:
    http://www.govacuum.com/agbelhoovpar9.html

    Now, once you have a new belt, this repair is pretty straight forward. I'll explain step by step what you'll need to do to change the belt.

    Step 1. Make sure your vacuum cleaner is unplugged. The easiest way to change the belt in your vacuum is to turn the machine upside down, so the handle is on the ground holding it up, then lean the vacuum over a counter top or work bench.

    Step 2. Remove the bottom plate of your vacuum cleaner. You'll see on the bottom of the vacuum 4 screws that are located on each corner of the brush, remove all 4 screws, and lift up on the bottom plate that covers the roller brush.

    Step 3. After removing the bottom plate, you should now be able to access the roller brush completely, and you'll probably also notice that the belt on the right side of the roller brush is broken. You may just remove the broken belt completely and throw it away. Lift straight up on the roller brush itself to remove it from the vacuum.

    Step 4. Test the roller brush. After something gets stuck in the brushes, and it causes the belt to burn, there's also a good possibility that your roller brush may need replacing as well. Also the roller brush will wear down over time, and the brushes will wear down as well, greatly reducing the cleaning ability of your vacuum. You'll want to test your roller brush, to ensure that it spins freely. If it doesn't, then as you install the new belt, it's possible it could also break immediately. To test the roller brush, remove it completely from the vacuum. Holding just the end caps of the bar with your fingertips, try to spin the brush in your hands using your thumbs. This is how it should look when you test your brush (the roller brush is to a different machine, but testing it will work the same):

    3a76171.jpg
    The roller brush should spin at least 3 or 4 times in your hands on each spin. If the brush will not spin at all, or you feel some resistance when spinning it, then you'll probably want to go ahead and replace the roller brush as well at this point.

    Step 5. Once you have your new belt, and new roller brush (if needed), it's time to install them. First wrap one side of the belt over the metal motor pulley in the back of the vacuum, opposite the roller brush. Now after you have one side of the belt wrapped around this metal pin, put the roller brush through the other end of the belt. Using the roller brush as leverage, stretch the belt with the roller brush inside of it back into the roller brush tray. You'll notice that on the left bearing cap on the end of the roller brush, there's a little rectangular shaped notch. Make sure that the rectangular notch is vertical, and slide this end into the agitator housing first, then fit the other side (circular notch) into the housing. With a little bit of elbow grease, you'll be able to stretch the brush with the belt back into place.

    Step 6. Test the belt and the brush before putting the bottom plate back on. To make sure that belt and brush are properly installed, pull the belt forward towards the brush, and make sure that the brush spins while you're pulling the belt. If the brush does not spin, then either the belt is pinched underneath of the roller brush, or the brush is bad / installed incorrectly. Make sure that the brush spins freely before reinstalling the bottom the plate, otherwise the belt will burn and break again as soon as you turn on the vacuum.

    Step 7. Reinstall the bottom plate, and screw down the four screws. Now you can turn the vacuum on, and make sure that the brush is spinning. If the brush is not spinning, repeat the steps above to make sure that the belt and brush were put in correctly.

    That should fix your problem. Ideally you should change your belt at least once a year. Even if the belt doesn't break, it will stretch out. When the belt is stretched out, it will not pick up as well as a new belt will.

    If you have any problems, or questions about how to do it, please feel free to use the Clarification Request here on the Fixya repair page, and I'll be more then happy to answer any follow questions for you.

    Change the belt


    Hi There,

    Here's how you can replace the belt on your Eureka SmartVac 4870. I have taken pictures of the repair to help you better with this.

    Here's what you'll need in order to complete this repair:

    - Eureka Style R Extended Life Replacement Belt, Part 61110
    - Eureka SmartVac Model 4870 Roller Brush Assembly, Part 61520 (Only if the brush no longer spins, or the brushes are worn out)
    - Phillips head screw driver

    Step 1. Turn the vacuum upside down so that the brush roller is facing upwards. Unscrew the three screws that I've highlighted in red.

    56134d4.jpg


    Step 2. Remove the bottom plate after unscrew the three red highlighted screws. Once you remove the bottom plate, you'll have full access to the roller brush and belt area. Remove the roller brush by pulling straight up on the roller brush itself. Discard old belt, and test roller brush to ensure that it spins freely by holding the very end of each side, also called the bearing caps with just your finger tips. Try spinning the brush with your thumbs. The brush should spin several times around with each spin. If you notice the brush doesn't spin at all, or if you feel some resistance when you spin the brush, this means that your bearings are either gone, or will be soon. It may be time to consider a new roller brush at this time.

    16ceeba.jpg

    Step 3. Remove the new Eureka Style R belt from the packaging, and wrap one end around the the metal pin, on the opposite side of the roller brush. This pin is actually the motor shaft that spins the belt, which spins the brush.

    81c4db4.jpg

    Step 4. Wrap the other end of the belt through the side of the roller brush that has the pulley, and use the roller brush to stretch the brush roll back into the agitator housing. Make sure the end caps fit in the housing correctly by making sure there are no gaps between the roller brush housing and the end caps of the roller brush.

    010b671.jpg

    Step 5. After reinstalling the roller brush back into the housing with the belt attached, pull the belt forwards towards the brush. The brush should spin when you do this. Make sure that the belt is not pinched underneath of the roller brush or this will cause the belt to break immediately when you turn the vacuum back on.

    Step 6. Reinstall the bottom plate, making sure that the little notches on the front end of the bottom plate tucked underneath of the reverse notches on the bottom housing of the vacuum cleaner. Tighten all 3 screws back into the bottom plate. Make sure the vacuum is set to carpet mode, and turn the vacuum on.

    If you have any questions about this repair, or if you notice that the roller brush stops when the brushes hit the carpeting, please just use the clarification request form here on the Fixya repair page. I will then be happy to walk you through a little more advanced repair of replacing the clutch in the Eureka SmartVac that controls the rug/floor switch. Most of the time though the belt will be all the vacuum needs.

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:

    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:

    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.

    I replaced the belt with part# 40201 on my Hoover model# U5473-900; to only have it break again in 5 seconds! Is there something missing that holds it on that little bar?


    Greetings,

    When a brand new belt breaks in 5 seconds, this can only mean 1 of 2 things.

    1. The roller brush itself may be bad and need replacing. If the roller brush's bearings lock up, and the brush can no longer spin freely, this will cause the belt to burn up immediately after you turn the vacuum on. You may test your roller brush by taking it out of the vacuum, and hold it on the very ends of the brush with your fingertips. Make sure you are only holding the bearing caps and not the brush itself. While holding the two bearing caps with your pointer fingers, try to spin the brush with your thumbs. Does the brush spin freely? If no, then you'll need to buy a new roller bush for your vacuum, unfortunately the bearings are not sold separately on Hoover vacuums. If the brush did spin freely (you should get at least 7 rotations out of one spin) then see reason number 2 below.

    Your model uses Hoover Agitator Brush Part 48414132.

    2. The belt was installed incorrectly. When a belt breaks immediately like this it can also be a result of it not being installed properly. When installing the next belt, after you have put the roller brush back into place, pull forward on the belt to make sure that the brush spins when you're pulling forward. Sometimes I pinch the belt underneath of the brush roller, and it will not spin freely, and will burn immediately if the belt is pinched.

    It really can only be one of these two problems. I hope that this repair solution was helpful to you. If you need me to clarify something, please just request clarification here. If it did help, please be sure to rate my repair Helpful. Thank you so much!
