I have a DC14. It started making a noise when turned on and a smell. I removed the main body to get a better look, and it seems that the motor is sparking. Does this sound like something which can be fixed, or is it time for another machine?

If the air flow is blocked, then yes you will get overheating of the motor and a funny smell. One approach is to remove the part closest to the motor, and if the motor then runs okay, the blockage must be downstream. Perhaps there is an online manual that explains how it comes apart? Another thought is that the bearings might be going bad. Might be worth taking this vacuum to a repair man.

i am afraid that is ur motor that has blown this can be easily repaired by dyson ring the no. on the vac full service and repair only £60

You need to replace the belts. When they are worn they put off a smell. Here is the belt you need:

Dyson DC14 Belt

It sounds like the motor has overheated and has now been irrepairable damaged.
The motor has a built in over-current trip to protect itself (and you if it seriously overheated and caught fire). This normally automatically resets itself, however if the motor has just about had it, the moment it is switched on, it just trips again.

The primary cause of motors overheating is that the filters are not cleaned or replaced frequently enough. Dont be fooled by Dyson's "lifetime filters". They need to be regularly cleaned and replaced when necessary.

Replacement motors are avaible on eBay for about £25, however repalcing one requires good DIY skills and tools.

Have a look at www.dysonmedic.com and see if you feel you can tackle it yourself. If not, take it to a repair shop or call the Dyson helpline.

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.

Hi,

The sound you can hear is the clutch slipping the machine is designed to do this if the brush roller is jammed or foriegn object obstructing brush roller.

Remove the sole plate by turning the 3 plastic screws to unlock pull off sole plate now look for anything that is stopping brush from easily turning. If nothing obviouse but roller hard to turn by hand remove the brush roller & check the bearings at either end of the roller if they are siezed up A new roller will sort this out.

If brush roller is turning freely then your problem will be warn out clutch this will need replacing.

Its A lot to explain so try this site it has clutch removing manual for Dc14. http://dysonmanuals.llc.nu/

If you are getting a motor smell, then either something got into the fan and stalled it, or the motor went bad. Afraid it will have to be taken apart and checked. Can you turn the brush roll, if not there maybe a problem there.

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.

Hi. Dont fully understand what you mean by (It was plugged going into the empty cylinder) If it is dead check mains lead to switch for any internal break in the lead,This is very common it usually breaks where it enters the machine. If its not the mains lead Check switch unit. I doubt its the motor unless it was giving a burning smell with a popping noise,
