I have removed the hose and it is clear but noticed that at the base where the hose connects, a white tube is blocking the opening. How to position it correctly? Any help would be apprieciated. Thanks

SOURCE: have a dyson vacuum -

Hi combe,

Its either that(you had it right the first, time, run a snakewire thru it) that or Dyson's ads are lying "Dyson's never lose suction", lol. It just kills me when I watch him and Orek talk about vacuums like its the second coming of christ. All you should need is a phillips head screwdriver.

SOURCE: HELP!!dyson vacuum only 2 years old model DC18

its the ball cradle assembly. There is a little clip that changes the direction of the suction. that clip breaks all the time and causes the internal direction valve to stay in one position. unfortunately dyson doesnt sell these parts separate, you will have to purchase a new cradle assy. let me know if you need a part #

SOURCE: i have a dyson DC18 slim all floors i have no

I realize this questioned was posted >1 year ago, but in the event you still have the poor suction/wheezing or if anyone else has this issue, here's what worked for us.
Use a plumbers sink snake to unclog the "pipe". I thought it was the pipe on the right hand side (when you're looking at it) which needed to be unplugged. There was a little in that size, however we retrieved the nastiest "hairball" out of the left hand side (when you're looking at it) and after removing that, and re-testing, the suction was incredible. In addition, the "wheezing" noise was no longer there.
Good luck

Cannot reconect hose at base dyson dc8

Hi Joei, it's Jack at Dyson.

DC18's hose should clip back onto the machine without difficulty. It just pushes into place, and you should hear and feel a click as it locks securely. You might find the tips in our Support guide useful:

If you'd like further guidance on reattaching it, please give the Dyson customer Helpline a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA), or 1800 239 766 (AU).

No suction no blockages was working fine

Hi there,

I'm sorry to hear you've had difficulty with your DC18. If your machine isn't picking up as well as it should be, there may be a blockage in the machine.

The vaccum works fine but when I use the hose the brushes don't rotate and neither does the hose have any suction

Hi there,

I'm sorry to hear you're having difficulties with your DC18. The brushbar is designed not to rotate when the machine is standing upright, so this is nothing to be concerned about.

However, if there is no suction from the hose, there may be a blockage in the machine. To resolve this, please follow the steps shown in our online Support guide:

You may also want to give the filter a wash - in normal use, this should be done at least once every 3-6 months, as shown in the video below. Use cold water without detergent, and allow at least 12 hours for the filter to dry completely somewhere warm before replacing it.

If you'd like any further assistance or advice, please call us on 0800 298 0298 (UK), or 1-866-693-9766 (US).

Best wishes,

Hose lost suction

Hi Aaron,

I'm sorry to hear you're having difficulties with your DC18. If your machine picks up through the cleaner head, but not through the wand, it's likely that there's a blockage somewhere in the wand or hose. The easiest way to check for this is to follow the steps shown in our online support guide:

This should resolve your issue, but if you'd like any further assistance, please give us a call free on 0800 298 0298 (UK), or 1866MYDYSON (US).

Kind regards,

On my DC18 there is no suction at the wand.I took it apart to make sure there was no clog. What switches the suction from the bottom to the wand? Thanks John

  • I actually answered a question just like this the other day. On the DC18 the switch is automatic. When the vacuum is upright the suction is automatically to the hose.
  • When you tilt the handle back the suction is automatically to the floor.
  • If you took things apart and cleaned them and have no suction through the hose when the vacuum in the upright position then this is a manufacturers defect.
  • The way I know this is for the other persons issue I called Dyson directly because I wanted to see why I could not see a switch and they told me there was none, it was automatic.
  • Here is the good news. Dyson offers a full 5 year warranty and the DC18 has only been out for 4 years. So every DC18 on the market is still under a full warranty.
  • What Dyson told me is this. Contact Dyson and they will see if their is a repair center near you and if so then you can drop it off there for a 100% free warranty repair.
  • If there is no repair shop in your area then they will ship it both ways and repair it 100% free on Dyson.

  • Here is there contact information.
  • Here is the link to choose the country should you be outside the USA. If you choose that link the when the page loads got to the lower right of the screen to the fine print and click on "contact us" and the information will show up.
  • Here is the USA information
  • Dyson Inc.

  • I would just give them a call. They seemed friendly enough to me. For the record the lady I helped before confirmed to me they did perform a warranty repair free for her.
  • Hope this helps and thank you for using Fix Ya

Hi my dyson dc18 has great suction from wand but when you got to use the vac for floors little suction but wand still got suction even while vacuming floors is it suposed to stop suction from wand

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
