"brush bar spins erratically"

The hose has plenty of suction . The base has some suction but not much and the brush bar spins erratically. It will start to spin quickly and then slow way down, then quickly etc. The motor is strong and steady so I don't think they are related. There don't appear to be any clogs and the belt seems alright, it is a few years old now.

Belt needs to be replaced, it has stretched to the point that under load, it won't turn the brush roll like it should, so I would advise replacing the belt. And while you are doing that, check the brush roll and make sure the ends turn freely, if not, then replace it also. Then check the dirt inlet while you have the brush roll out.

Plenty suction from wand, but when you tilt back to vacum no suction at base but brushes are turning


Hello,

There could be a few things that would cause your Dyson to have no suction. I will give you detailed step by step instructions along with pictures on how you can diagnose this.

Possible Problem #1. The first problem is extremely common. In fact, we probably see between 2-3 of these problems every week. It mostly happens after people take the bottom plate off the vacuum in order to clean the roller brush. What happens is when they reinstall the bottom plate, they put it on on incorrectly. It's actually very easy to do. When the bottom plate (soleplate) is installed wrong, there will be a gap between the bottom plate, and the agitator housing, or the purple tray the roller brush sits in. This will cause the soleplate to be a few inches higher off the ground then it should be, preventing the brushes from even hitting the carpet. This makes it seem to the user that vacuum has lost suction power because without the brushes hitting the carpet, the machine will not pick up very well on floors, but when they use the attachment hose there's plenty of suction power.

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:


8b953d0.jpg
I would say probably 6 times out of 10 this is the problem with the customers machine. If you checked the soleplate and it is installed correctly, move on to the second possible problem.

Possible Problem # 2. Turn the vacuum cleaner upside down so the brush roller is facing upwards. I found the easiest way to work on it is to put it on a counter top or work bench. On the left hand side behind the roller brush you should see a flexible transparent hose that goes from the motor to the agitator housing. This hose actually has a lot of strain on it when the vacuum cleaner is in the reclined position. When the first few series of Dyson DC07 models came out, they didn't make this hose long enough, so when the vacuum was in the reclined position, it would put too much stress on the hose, and cause the hose to actually crack, usually right where the end of the hose that goes into the agitator housing. Examine your hose and see if you have any visible cracks in this hose. If you need to you may just remove the entire hose assembly by pulling on it. It will easily come right out of the machine so you can inspect it better. Here's a picture of where the hose usually cracks:


54cb5e5.jpg
This would also explain why the vacuum works fine when using the attachments, but not on the floors. The attachment hose uses a different suction channel, and when the machine is in the upright position, no suction goes through this hose. If you do find a crack in this hose, the this hose needs to be replaced. Here's a direct link to that hose on our GoVacuum website.

Possible Problem #3. I would suspect that this may not be the problem, but if neither of the solutions above worked, then try this one. Dyson's in general are prone to clogging. There are a few clog ports throughout the vacuum cleaner that were added there due to Dyson prototypes becoming clogged at these points. Here are pictures of how and where to check for these clogs. Simply remove the suction port covers at both of these locations:


8b33cd4.jpg

be63721.jpg

Possible Problem #4. If none of the above solutions worked for you, try this last one. The Dyson DC07 models use a clutch mechanism that stops the roller brush from spinning when changed from carpet mode to bare floor mode. This clutch mechanism is a notorious problem with all Dyson models, in fact they were such a problem that Dyson had to redesign the DC07 model to a non-clutch system. Even if yours is one of the newer ones that don't use a clutch, yours still has a belt inside. You can tell if your model uses a clutch or not by the shape of the roller brush. If your brush is a perfect cylinder shape, yours does NOT have a clutch. To check and see if the clutch or the belt have gone bad, first release the handle on the vacuum as if you were vacuuming carpets. Make sure the machine is set to carpet mode. Now while the handle has been released, turn the machine upside down and see if the brushes are spinning. If the brushes are spinning then turn the vacuum right side up and put the brushes on the floor. Can you still hear the brushes spinning when they are hitting the carpet? If yes, then this is not the problem. If the brushes however are NOT spinning, this indicates either your brush roll, clutch, or belt have gone bad. ....

Hi my dc07 has lost suction on the roller, but not on the hose there are no blockages cyclone still strong any ideas thanks


Are the brushes in the base of the vacuum spinning? You wont get much suction from the base of the hoover if the brush bar isn't working?

Lie the vacuum on it's side and turn it on. If the brushes aren't spinning then your belt has either come off or broken. I suspect this is the cause of your problem.

My dyson dc17 animal will pick up via the hose attachment but there is no suction when you use the regular vaccuum on the floor - you can hear the difference in the suction once you put the floor part down...


Hi its Darran at Dyson.

Check that the brush control dial is in the centre position when upright and then moves forward when the head is released. If the brush bar is still not spinning when switched on in the vacuuming position, check the base for blockages and remove any threads or hairs from the brush bar as outlined in your user guide or on our website.

If you are still having difficulties, please contact our Helpline on 0800 298 0298 (UK) or 1866MYDYSON (US).

Kind regards

With the DC14 in its upright position, and looking from the back, there is an access hatch just to the right and bottom of the dust canister. Remove this and check for any obstruction. With the hatch still removed, tilt the handle back (as if vacuuming a floor), and you should spot that the mechanism in to which the access hatch fits changes over from one hole to another. This is how suction is transfreered from the telescopic arm to the brush bar when the unit is taken out of the upright position.
With the handle tilted back, the hole you can see is one end of a flexible pipe that leads to the brush bar. Check for any blockage and/or foriegn objects. If there is no obvious problem, you'll need to check the other end of the pipe. You can do this by removing the toe plate on the bottom of the brush bar area. The plate is held by 3 or 4 half turn fasterners - a 5 pence piece is ideal for undoing these.

If still no joy, the only other thing it might be is that the brush bar isnt spinning - this isnt actually lack of suction, but without brush rotation any upright hoover is far less effieicnt at picking up bits from the floor. Brushes not spinning on a DC14 is quiet a difficult thing to fix on a DC14 as there are two separate rubber belts, one of which is hidden under a plastic cover. There is also a clutch mechanism between the belts that can cause problems some times.

The machine will not suction - it will spray and spin the brushes but will not suction - the power is going to the machine, but it will not suction.


Disconnect the suction hose. While running, check the suction port if it works, by putting a piece of paper. If the paper is taken in, then it is oK. Now, check the suction Hose for breaks or opening before the suction head. Breaks or opening breaks the suction power at the suction head. Loose connection between the suction pipe and the suction port also must be check as this will also cause the same
problem. You may need to replace the suction hose

Check to see if the brushes are spinning, if not, undo the four screws on the plate over the brushes and the belt is easy to get at. Replacement should be available in any spares store.

as the hose fits into the base (if i am correct) the power at the base should be fine, make sure the base is clean and free from blockage, you say the brush doesn't spin, has the belt broken, if so replace it, (very cheap) and only a couple of screws to undo, the roller not rotating will effect the power of suction dramatically, start from there and see how you go if i have helped please rate me
