I just cleaned out my Dyson animal, which had no suction. Now, all put back together, the suction is there but the machine makes a long lasting sound when I shut it off.

Hey, It's Jim with Crucial Vacuum,

If you're hearing an odd sound that is somewhat prolonged after you turn off your vacuum it be that your belt or brush roll needs replacing.

If you have suction and there aren't any clogs in your vacuum your belt might be worn and loose, which could give off an odd noise as it slows down along with the brush roll upon you turning off the vacuum.

Does your Dyson DC14's belt lack tension? It may be hitting the brush roll at the wrong angle. Same deal with the brush roll itself. Turn your vacuum over and take a look at the bristles. Are they loose or worn down? These are indications that its time to change these two parts of your Dyson DC14.

If these parts aren't in top shape or attached properly they're bound to make a number of odd noises.

We do offer low cost high quality replacement parts for Dyson DC14's. They can be found at the below link:

Hi. My dyson dc14 wand works great then all of a sudden if something too big or even just the carpet it makes a sucking noise & the purple round bit in the actual Hoover makes a funny noise & then...

Sounds like a blockage. I have a DC14 and I have never had this problem. You can easily remove the wand from the flexible hose and the flexible hose from the machine to check for a blockage. Don't allow paper or larger items to go into the machine, especially the wand, pick it up by hand first. Find the online manual here:

I have a DC14 upright. When the Dyson is upright and switched on it runs fine. Whrn I lower the handle to start hoovering, the Dyson makes a loud noise

Hi there,

Sorry to hear you're having difficulties with your DC14. The brush control of your cleaner includes a safety feature which makes a ratcheting sound to warn you when the brushbar is jammed. For a step-by-step illustrated guide demonstrating how to check for and remove obstructions from the cleaner head and brushbar, please see the link below:

By removing any threads, hair, or other obstructions which may be preventing the brushbar from spinning freely, you should be able to resolve your problem. However, if you've tried this and are still having difficulties, please get in touch with us directly so one of our experts can run through some troubleshooting over the phone with you. You can call us free on 08002980298 (UK), or 1866MYDYSON (US).

Kind regards,

Dc14 when turned on makes a different noise louder, and it smells like it burning and sparks at the bottom back just below the pipe

I guess you don't need me to tell you you've got a major electrical problem!  Question is, what do you need by way of help?  At the very least you will need new carbon brushes for the motor, and it's quite likely that you may need a complete new motor.  Trouble is that Dysons generally are not easy for the amateur to get in to and Dyson do not make technical manuals available.  It's a while since I had to work on a DC14 and I can't remember how to get at the motor.  The best I can do is spell out your options: 1. Try to do it yourself and risk breaking something, 2. wait for a reply on this site from someone else (although to judge from the number of unanswered Dyson problems here, you may wait for ever),  3. take it to a specialist repairer or call Dyson direct for advice (but they won't give you any guidance for doing the work yourself).  
Good luck.  If you need to ask specific questions, post again here and I'll help if I can.

Noise when turned on or off.

I don't think you need to worry about the noise. Dysons run hot, it's just one of those things...

Dyson DC14 all floors.

sept 30,08 bought dc14 all flloor. After 3 to 4 uses it started making lots of noise when on carpet setting. I examined the roller brush and it was cracked at one end. I returned it Oct 13 ,08 and got another dc 14 all floor. Now this one after 2 uses has the same problem only a larger crack in the brush and a small piece of the brush broke off. Very dissapointed.
