Question about Dyson DC27 Bagless Upright Vacuum

1 Answer

My Dyson is not working properly. It work to vacuum with the hose, but not in the upright position. When I start is sounds normal for a second and then becomes loud and doesn't pick up anything. The noise is coming from what look like an air valve(?) It is circular and foam like circle piece that pushes inward. This is being sucked in and creating the noise and loss of suction. Please help!

Hi there,

I'm sorry to hear you're having difficulties with your DC27. The part you're describing is the suction relief valve, which protects the motor if the machine is used when blocked.

For guidance in locating and removing any blockages, please follow the steps shown in our online support guide:

http://www.dyson.com/support/help.asp?article=1344&product=DC27-TC

I'd also recommend giving the filter a wash. Under normal use, this should be done at least once every 3 months. Use cold water without detergent, and allow up to 24 hours for the filter to dry completely before replacing it. For assistance, please refer to the video linked below:

http://www.dyson.com/support/help.asp?article=1466&product=DC27-TC

Following these steps should enable you to resolve the issue without further assistance. However, if you're unable to resolve the issue, or if you'd prefer to speak to someone in person, please get in touch with us directly so we can provide the help you need as quickly as possible. You can call us free on 08002980298 (UK), or 1866MYDYSON (US).

Dyson no suction in upholstery wand


Hi there, it's Jack at Dyson.

Like most Dyson upright vacuums, DC18 is engineered to divert suction to the hose and wand automatically when it's standing in the upright position. If your DC18 doesn't seem to have suction from the wand when standing upright, you may have a blockage in the hose or wand. Please follow the steps shown in our online Support guide to check for this: http://www.dyson.co.uk/support/dc18/dc18-all-floors/my-machine-is-not-working/machine-not-sucking-picking-up-as-well-as-usual/how-to-wash-filters/no/remove-the-wand-from-hose

It's also a good idea to give the filter a wash - in normal use, this should be done at least once every 3 months as shown in the video below. Use cold water without detergent, and allow at least 24 horus for the filter to dry completely before replacing it.

I'm confident following these steps will resolve the issue. However if you'd like any further guidance from our experts after you've given this a try, please give us a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Air escaping from top of handle


Hi there, it's Jack at Dyson.
It's part of the design of our upright vacuums that when the machine is standing upright, the suction is diverted to the wand, ready for above-floor cleaning. You can find out more about how the hose, wand and tools work on our Support page:

http://content.dyson.com/support/help.asp?article=1255&product=DC28-ANIMAL

It sounds like your machine is working normally, but if you'd like any further assistance please email us at askdysonUS@dyson.com and we'll be in touch as soon as possible.

I have a dyson 07. Vacuum works fine, great suction using the hose. How do I switch to using the carpet vacuum. (I lost my instruction book) Thanks


If this unit has a suction hose built in to the handle, the carpet vacuum should start working after you return the handle hose to the proper position.

Dyson DC 14 animal bagless--unable to use wand


Hi.

Try these tests & tell me the results.

Remove the hose & wand completely from the machine it unclips at the bottom of the back.

Leave handle in full upright position & switch on do you still get the sound of something blocked ?

If yes remove the (U) shaped inspection port again at bottom back of machine now repeat last test what happens ?

Please reply with your answers.

Can't get it to ****!!!


Worked on one with your same problem of poor suction and won't stand up. On the left side of the handle, near the bottom, the port cover isn't on correctly. Take it off, put the handle in the upright position then reinstall the cover.
