The hose is blocked, so you have very little suction at the end. The vacuum in the hose is pulling the hose shorter. With the vacuum turned off, push a broom handle through the hose to dislodge the blockage.

Hi Marin, it's Jack at Dyson.

DC40 is a powerful mid-size Dyson upright vacuums, and we wouldn't expect you to have any concerns about performance on hard flooring or carpet. As long as the machine is used and maintained as described in the User guide we would not anticipate a change in performance, and we're on hand to help if Dyson owners need assistance.

It's important to note that for effective pickup, the cleaner head needs to form a close seal with the floor surface. Simply placing a hand under the cleaner head does not give an accurate idea of suction as you're not creating a seal, as you would be when you place your hand right across the end of the wand or hose. If you turn on and recline the vacuum, turn off the brush bar then lower the cleaner head onto something like a sheet of newspaper, you should see the newspaper held tightly against the soleplate by the vacuum's powerful suction.

We're keen to discuss this with you, and to help ensure your DC40 is working as well as it should be. Please email your full contact details to my colleagues at [email protected], and one of our experts will be in touch as soon as possible to provide further assistance.

Hi there, it's Jack at Dyson.

I'm sorry to hear you feel your DC40 has too much suction. This sounds unusual, and in order to help you resolve things we would need to take some further details about your machine, and the particular flooring type you're having difficulty with.

When you have your machine to hand, please call us directly so we can talk you through some simple troubleshooting checks to make sure everything is correct with your DC40. You can reach us on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

We'll look forward to speaking with you.

On this model dyson there is a flapper valve that opens when the handle release is engaged. It switches the air flow from the hose to the floor nozzle. They break there all the time, and you have to take it to a dyson repair shop.

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 where the hose 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 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. ....

Hello,

There are several things that this could be. Probably the most common problem that we see when customers come in with this problem is actually a fairly simple problem to fix. Here are just a few things that this could be.

The fist possible problem is a VERY common problem actually.

If you are getting suction power from the hose, but the vacuum still doesn't pick up on the floors, I think that these solutions should fix your problem. If you just replaced the clutch mechanism, the roller brush should be fine, but turn the vacuum over on it's side and make sure that the roller brush is actually spinning while it's on carpet mode. If none of these problems fixed your Dyson, please use the Clarification Request, or leave another comment here on the Fixya repair page, and I'll be happy to further diagnosis the vacuum cleaner with you.
