Hello, Im assuming that your unit has no suction. If this is the case, it is still plugged. Run a stiff wire through all the hoses, starting at the on behind the bristle brush. Make sure all the bagless filters are completely cleaned.
It automatically switches over when you disconnect the hose from the power nozzle. No suction it getting to the power nozzle, so the suction is only through the attachments. If there is no suction through the hose, check for clogs in the hose and in the tank where the hose plugs in. Also, check the screen at the bottom of the tank. If there is a clog in the hose or tank, then there also will be no suction to the power nozzle.
Remove all clogs and you should get suction.
- Check the dirt cup to make sure it is empty. - Your vacuum has 3 filters. Dirty filters will restrict air flow. The filters may be hand washed in cold water with mild detergent. Allow them to completely dry prior to reinstalling them. The white HEPA media post-motor filter is not washable.
- Lift the upholstery hose from the bottom holder. Check for suction at the end of the hose.
If there IS good suction at the end of the hose, please unplug your machine from the outlet and try the following:
- Ensure the hose is firmly pressed into the lower hose outlet on the back of the vacuum. - Check to ensure the brush is rotating. If it is not, remove the plate on the bottom of the vacuum. Check the belt and clean the roller of dirt and debris. - Check the lower hose for clogs by removing the screw which attaches it and lifting the hose up to clean it out. Also, remove the larger hose by twisting it off and using a broomstick handle, push any dirt and debris through the hose.
Remove the machine side of the hose--is there suction at the machine? If so, run a broom handle or similar through the hose to dislodge the clog. If no suction at the machine, you may need to fish out debris with a hooked stiff wire from the port. Remove the bag and examine the port area underneath for similar clogging. Finally, check the brush area underneath the machine bottom plate for more obstruction. Also, check the brush assembly for debris accumulation. Remove the drive belt and check for free turning of the brush. If turns hard, remove the brush, clean the bearings and roller pins, then apply a small quantity of light oil like 3-1 or sewing machine oil. Hope this helps!
From your description of the problem, it sounds as though the wand/hose is blocked. To test this, please remove the wand from the machine and switch on, testing the suction from the top of the wand handle. If the suction is poor, remove the wand from the hose and test the suction from the top of the hose. If its strong from the hose itself, the wand is blocked and you will need to clear this.
If there is poor suction from the hose, you can remove this by unclipping it from the base of the machine and can then remove any blockages. It is also worth checking the hose for any splits or holes.

Check the sole plate where the beater bar is. You may have to remove the roller brush flap to get into the roller brush and then check the main dust channel beside it. Usually if there's no suction on the hose it means that:
1) The hose is blocked
2) The filters are needing cleaned / washed and dried for 24 hours or see my tips!
3) There is dust clogging after the beater bar/roller brush.
If the Dyson is throwing out dirt at the back, it could be three possibilities:
1) The main floor head suction channel is blocked. Check the sole plate where the beater bar is, or if you have a cylinder/pull along model check the floor heads and main extension pipes.
2) Check all the inspection tubes especially the bottom part where the main handle hose is. Also check the filters are clean as well as the Cyclone shroud honeycombs are completely unclogged. Use of the upholstery brush is ideal for dust removal on the cyclones.
3) Check the main inspection areas on the Dyson as sometimes a back log of clogged dirt can get stuck. Also check the dust channel points when then bin is taken out.
Hope all this helps!
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.
Make sure you have a good bag installed in the vacuum and the door is properly in place. Remove the attachment hose from the bag chamber and turn the machine on. You should have good suction coming from the hose inlet. If you don't you have a problem in the bag chamber. Bad bag, door is not on correct, door is defective, dirty secondary filter.
Connect the hose back to the machine and pull the other end out from the bottom, and turn the machine on. You should have good suction there. If you don't you have a clog or hole in the attachment hose and it needs to be unclogged or relplaced.
Reconnect the to the bottom. Flip the mahine upside down. Take the screws out of the bottom plate and remove. Remove the brushroller and belt. Turn the machine on and you should have suction at the inlet coming off the brushhousing. It you don't, then you have a clog in the nozzle hose and it needs to be removed. It will probably be more accessable from the bottom side since that is the way that it entered.
Sometimes a suction problem can be confused with an brush problem. The belts on that machine should be replaced every 6 to 8 months because they will strentch and wear. This is an inexpensive maitainance that will dramatically improve its function. Part Numbers are 38528-035 and 38528-034
Generic problem for all Vacuums No suction no suction I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
I’m not sure if you have a canister or an upright but there are thing you can check on both machines, canisters – you can check the suction from the end of the hose and work your way back to the canister, start with the end of the hose, then remove the hose and check the suction on the vacuum – most clogs are in the hose – if you have a hose clog run a steel ball thru the hose to see if goes thru all the way if itdoes than check the bad and the filter, if those are ok you may have a bad motor. If it is an upright, make sure the height adjustment is correct and is adjusted correctly, then use the steel ball and run it thru the attachment hose to see if that is blocked or clogged. Then check the belt and the extension wands to see if there is a blockage there as well, if you have good brushes and the tone changes from high to low and the brushes are actually hitting the floor, then you may have a motor problem and then you might have to replace the motor or fan assm. I hope this was helpful.
