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:

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 whPlenty suction from wand, but when you tilt back t - 54cb5e5.jpge usually cracks:

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 fPlenty suction from wand, but when you tilt back t - 8b33cd4.jpgogs. Simply remove the suction port Plenty suction from wand, but when you tilt back t - be63721.jpgoth 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. ....

SOURCE: Dyson DC07 Original won't pick up at base

Hi,

Lie machine on its side pull back handle as if vacuuming & switch on (KEEP YOUR FINGERS & ANY LOOSE CLOTHING CLEAR OF BRUSH ROLLER)

Brush should spin if it doesnt ensure clutch control knob on side of machine is in drive position if it isnt rotate knob by hand to drive brush should now spin.

If it doesnt & your machine has A clutch either clutch will need replacing or belts will need replacing.

Manuals are available to replace belts & remove the clutch from this site http://dysonmanuals.llc.nu/index.htm

SOURCE: Belt on but brushes not turning

I had the same problem . The issue was with inner belt that might have sliped the main shaft. Well My model was Dc07 - You may have the same design for the belts. You need a Trox -15 long screw driver. Open the belt casing by unscrewing the 3 hex screws. You can slip the main belt back on. I hope this may fix your problem.

Did you dropped your vacumm ?

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.

SOURCE: hi my dyson dc18 has great suction from wand but

My Dyson dc18 had the same symptoms. The wand worked well and the floor bar had no suction. After removing pieces & shoving my fingers into the machine (no blockage) I found the suction pipe rotates between two positions (floor and wand). It looks like a piece of plastic broke on the outside housing, so it no longer rotates positions when the wheels are raised or lowered. My son found we can move the suction by sliding a finger into the mechanism behind the wheel cover, and rotating the plastic piece clock-wise or counter clock-wise until it locks into position. It's a big pain but it works for now. I wish I could find a replacement piece online. Patty

    Hi there, I'm sorry to hear you're having difficulties with your DC07. If it doesn't seem to be picking up as well as usual, it's possible that there's a blockage in the system - I'd also recommend giving the filter a wash. The easiest way to check for and remove any blockages is to follow the steps shown in our online support guide: http://www.dyson.com/support/help.asp?article=4&product=DC07-ANIMAL_US Under normal use, this should be done at least once every 3-6 months. Use cold water without detergent, and allow up to 24 hours for the filter to dry completely before replacing it. By clearing any obstructions and washing the filter, you should be able to resolve your issue without further assistance. However, if you've tried this and are still concerned, it's probably best if you get in touch with us directly. You can call us free on 08002980298 (UK), or 1866MYDYSON (US). One of our experts will be happy to run through some troubleshooting over the phone with you, and to recommend the best course of action. Kind regards, Jack Dyson Online Customer Support

    My dyson dc25 has reduced suction at the base, suction is fine at the wand


    This is a guess but I have experienced it on other vacuum cleaners I have owned.

    Check the hose that connects the at the base for breaks. Not just the easy to disconnect one connected to the wand, the one that goes into the head, if you are sure there are no blocks I can only imagine this being a possibility

    dyson does offer a 5 year warranty if you have not past this age it might be worth sending out.

    Dyson DC28 - when using this in "carpet mode", I can hear and feel tons of suction being pulled through the wand, even though the wand is properly stowed as the handle for "carpet mode". And when this...


    There's no switch per sey, but there is a clutch activation knob, on the right side of the base, as you're standing behind the unit. There should be a Carpet or Hard floor setting, just two. Twist it to change from one to the other. However, all this is meant to do, as far as I know, is to turn on the brush roll or turn it off, by means of a clutch system. I don't think it has anything to do with the wand assembly.

    No suction - Infinity Shark Vacuum NV31C


    You might try sucking the sose out with another vacum from the wrong way. You might be able to remove the hose and push a broom handle or stiff wire through. If you have compressed air available, you could try that, outside.

    Im sure you have a clog and if you remove it, you will be back in business.

    You probably have a blockage somewhere in the hose or in the base where the hose goes in. Remove the plastic tube at the base of the hose by simply unclicking it and remove the obstruction.

    We have the Eureka EZ Kleen upright. We have suction through the hoses but not the main vacuum. The brush turns fine but the vacume does not **** anything up.


    THE HOSE BETWEEN THE DETACHABLE WAND AND THE BRUSH ROLLER AREA MUST BE CLOGGED WITH CARPET FIBERS. CLEAN IT OUT AND IT SHOULD WORK.
