Question about Vacuums

No suction, brushes move

You asked the previous person for the model. When in full upright and locked position it works. When reclined it doesn't provide suction, and the brushes move nicely. When using the tools, hose etc., it works. Any idea.

Well you did not provide make and model either. If a Hoover, there is a valve on some that depending which position the handle is in, will be open or closed. It may not be working, so when in the upright, there is suction for the hose, but when you tip the handle back, the valve doesn't move and blocks suction from below. You will have to remove the top cover to check it out.

Brushbar not turning


Hi there, it's Jack at Dyson.

DC03 doesn't use a traditional user-replaceable belt. Instead it has a brush control clutch mechanism which allows you to turn off the brush bar when cleaning hard floors and delicate rugs.

If the brush bar doesn't seem to be rotating, it's worth double-checking you have the brush control set correctly. When the machine is reclined into the normal vacuuming position, the brush control should move to the Drive/On position:

Please note, as a safety feature the brush bar will never rotate when the vacuum is standing upright.

If you're confident the brush control is in the correct position, but the brush bar still won't rotate, please give our freephone UK Helpline a call on 0800 298 0298. We're available from 8am-8pm from Monday to Friday, and 8am-6pm on weekends. Calls are free from UK landlines.

No power to cleaning head


It'll help if you clarify if this is no power at all - the motor makes no sound, motor is on but no suction, and/or suction but the brush isn't spinning. If the latter, then there are a couple of possibilities. The bar should stop spinning when full upright, where the system will route suction to the handle for accessories. Try reclining the handle. there is also a switch for the brush clutch to engage (see the manual
http://www.dyson.com/medialibrary/files/dyson/support/downloads/uk/floorcare/manuals/DC25_Manual.pdf ), including page 8. The brush will also stop if there is a blockage.The checklist for clearing obstructions and resetting the brush bar (!) are shown on page 5 - there's a switch on the back to press twice, probably re-engaging a breaker.

Good Luck!

Dyson DC 25 power shuts off in upright position


To clarify, do you mean the suction and brush motion shut off in the upright position, or that the entire unit shuts off?

If the latter, most Dyson uprights shut off the brush unit in the full upright position and shunt the suction into the handle for use with the accessories. There is also an on/off for the brush, next to the main power button for the DC25. If it's off ( or stuck that way), no brush motion. The manual also notes, 'for use, turn on power and click the foot pedal in back to recline the unit.' (Link to manual here:
http://www.dyson.com/medialibrary/files/dyson/support/downloads/uk/floorcare/manuals/DC25_Manual.pdf See Page 8). The
'High Reach Cleaning' section also notes that the brush bar won't rotate when the vacuum is in the full upright position.

If you are completely losing power, the manual notes that the unit will shut off if the bar is jammed, or if there is a significant line blockage that makes the motor overheat. If this is happening, check the accessory line in the handle for blockage.

Good Luck :-)

My vac cleaner doesn't pick up.


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:

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, i have a panasonic eco max, the brush has stopped going round, the belt is as new and brushes clean.suction good from hose. Any ideas please? thank you


The brush on this model is controlled by the on/carpet/floor switch and will only work in the carpet position. If the suction motor is running then it could be the roller brush motor, but it's more likely to be the microswitch which stops the brush motor when the handle is returned to the upright position.

Brand new machine red button doesn't depress- it feels springy but doesn't click therefore brush not working


Hi Moya,

I'm sorry to hear you're having difficulties with your DC24. If the brushbar won't rotate, it may simply need resetting. Please follow the steps shown in the video below to reset it - make sure you have the cleaner reclined into the vacuuming position before testing it, as the brushbar will never run when the cleaner is standing upright.

However, if this doesn't restart the brushbar, it's best if you get in touch with us directly so we can help. You can call us free on 0800 298 0298 (UK), or 1866MYDYSON (US).

Kind regards,

X1.1 model has plenty of suction through the nozzle, but doesn't 'pull' across the floor anymore or pickup dirt when using upright


Assuming that the automatic height adjuster is working properly, most likely your Sebo needs a new brush roll because the bristles on the old one are worn to the limit. To test the height adjuster, put the machine in the normal operating position (with the handle not upright) then switch on - the green "down" light may come on briefly (or may stay on if the brush is worn). Then, leaving the machine switched on, move the handle to the locked upright position - the green "up" light should come on, and you may be able to see the whole machine tilt backwards slightly as it lifts the brush off the floor. If that happens, the adjuster is working properly and you definitely need a new brush roll.
I hope this helps. If you need more guidance, just post a reply here and I'll get back to you soon. Please remember to rate this answer as I do value feedback. Good luck!
