DC11 no power. Worked fine last time I used (2 weeks ago. Now wont turn on

Your new filter should last more than a week but you may have to clean it thoroughly after each use. One problem with vacuums that do not have a bag is the surface area of the filter is usually not very big so it does not take much fine dust to clog the pores of the filter. If air can't pass through the filter the motor will get hot and shut off.

Hi Pat, it's Jack at Dyson.

Performance issues are usually simple to resolve. DC11 has two filters - the 2-part pre-filter (the yellow plastic outer casing the the blue foam inner section) should be washed at least once every three months. The post-filter is engineered to last the lifetime of the machine without maintenance or replacement. If you have washed the post-filter, unfortunately this may have caused damage and we would recommend replacing it.

It sounds as if your machine has a blockage somewhere in the floor tool, wand or hose.

power head bar turns and vacuums but the head screams! What is wrong?

yes there could be a fuse and it is most likely in the motor chamber behind the motor

Hi,

I've never worked on a DC11 but have worked on several types of Dyson uprights. The following may or may not be relevant to the DC11 but may give you a few clues.

On the uprights I've worked on, if you remove the dust canister, underneath it is a clip-on cover with what's known as a post motor filter under it. This varies between models from a simple fibre pad, to a plastic encased paper filter very similar to the one that goes in the top of the dust canister. Having removed the clip-on cover / pad / filter, there should be a few more screws that when released will allow the motor housing to be taken apart.

The site www.dysonmedic.com is excellent, but doesn't yet cover the DC11.

Incidentally, I've just repaired my fathers DC07 which appeared at first to be a brushes problem. When I got it apart, it became obvious that the motor armature had a worsening fault whereby it was overheating so badly the over-current trip on the motor kept cutting out. The overheating was so bad that the bottom of the post motor filter was actually burnt !
Searching on eBay, I found a complete replacement motor for £18 inc p&p, but no listing for brushes. You may therefore find a) it isnt the brushes and b) you cant buy the brushes separately anyway.

Good luck !

the motor probobly blew out.

The commontator is worn or the mika seperating the sections is too high.

It is more than likely that you've caused blockage in your turbines. Plaster dust is very very fine and will have passed through your filter quite easily. It's also more than likely that the plaster dust has affected your motor.

If you turn it on and you hear popping, then motor is more than likely deceased. If you hear something like a valve releasing when you turn the machine off then there may be a blockage.

Probably best to refer to your local Dyson via www.dyson.com

Hard to say without seeing it, is there a function type knob that you would switch from carpet to hose? Did the hose attachment lid close ok? Other then take, if this is new, it has a years warranty on it, just take it to a waranty shop for repair.
