Hi, I have an upright DC03, brilliant machine. Mine wouldn't **** and had the following symptoms;
- it sucked ok from the top hole where the canister joins the unit - with the canister the dust didn't spin aroun inside the canister like it normally does and there was no **** at the hose end or brush end. - with the top of the canister attached (the cyclone) but not the bottom it sucked through the cyclone - the small valve on top of the cyclone unit was sucking heaps
this indicated to me the machine was sucking through the cyclone unit but when the canister was put on it was blocked - hence the tremendous sucking through the valve on the top of the cyclone. As far as I could see the cyclone wasn't blocked so I poked some wire down the tube inside the machine that runs from the bottom of the unit (where the hose sits) up to the bottom hole where the canister joins. 
The DC03 has 2 holes where the canister attaches, it seems like it sucks air through the top hole, through the cyclone and through the lower hole sucks the dust up this inner tube into the canister. Check that tube, shine a torch from the top hole and you should be able to see the light at the bottom. Make sure you clear it completely. 
Mine was very very blocked. I kept poking and removing dust until I could see light at through the tube. Works fine now.
Hopefully this helps someone as it took me awhile to work it out. 
Good luck

My Dyson 41 has just started only sucking through the tube


We've had our DC41 for 4 months now and suddenly noticed no suction at the base as well. Base motor works fine.Thought I'd take one last look before sending in for repair. At the base of the attachment hose near the motor is a small red tab. I depressed it and pulled the entire hose off the motor. Sure enough inside was a eyeliner pencil our daughter had unknowingly vacuumed up. I couldn't see it just peering the length of the hose. Even with a flashlight. You don't see mention of the small red tab but it allows you to see close up rather than peering down the hose if something is lodged near the motor. Apparently this pencil prevented the internal hardware to switch from wand to base suction when the handle is reclined in floor vacuum mode. These vacuums have strong suction and they will pull up the oddest things! Hope this helps!!

Dyson DC07 bagless - upright mode v poor suction, wand mode ok


Hi its Darran at Dyson.

From your description of the problem, it sounds as though the bleed valve is activating which only happens when there is a blockage.

We would recommend following the full blockage through as outlined in your user guide or in the Support section on our website at www.dyson.com.

Kind regards

No suction on wand of Dyson DC14 Animal


Hi its Darran at Dyson.

It sounds as though the wand handle is blocked. To check this, remove the wand/hose from the machine as if you were going to use it to vacuum the stairs. Switch the machine on and test the suction at the top of the wand handle with your hand. If the suction from the wand is poor, remove the wand from the hose and test the suction again from the top of the hose. If the suction here is good, then you know the wand handle is blocked. If the suction is poor at the hose, you can remove the hose from the machine and clear any blockages here.

For the full blockage procedure please visit the support section on our website at www.dyson.com.

Kind regards

I have a dyson dc 17 what is the best way to thourghly cleaning , so I can get better suction , also do you have a instruction manul to. I seem to have misplaced mine thanks


The first step towards improving the suction is to clean the circular HEPA filter. The filter also houses a circular sponge which should be rinsed and dried before putting it back. Check the HEPA filter to see if it needs replacement -- will look muddy! Another quick check is to remove the HEPA filter, run the vacuum cleaner momentarily in upright position to check if suction is restored at the hose end.

After doing this if suction is still poor or non existent, you should detach the transparent canister - a bit tricky since the release rod for the flap has to be aligned when you want to reassemble the unit.
Once the canister is removed, you should check and clean the center tube/shaft for any clogged dust (use a wire coat hanger if needed to pry out the dust). This tube gets clogged if the vacuum cleaner was used to pick up damp/wet spills etc.

Dyson DC 14 lost suction to beater bar/ suction to hose/stick


My Dyson DC14 had no suction...see if this works...turn the Dyson upside down...there is a length of hose that connects the bottom of the vacuum to the top, careful remove one end of the hose and check for debris...mine was clogged. Removed the clog and voila...it works. Thanks for the above info on checking the hose for cracks.
