This is my first post ... I imagine the answer is already on the forum but I haven't yet found it.
The brush bar starts spinning as it should, and stops as the handle is tilted back to about the 2 o'clock position. It remains stood for the rest of its travel.
It restarts as the handle is lifted back to that precise point ... it will do this as regular as clockwork, it never varies.
Any help would be much appreciated. You won't be able to over explain it as I'm not familiar with the names of the individual components.
Thank you very much

I could be yolk loom break, or brush switch.
Micro switch could have a blind spot on its internal contact, the cam could have a problem re it's spring but i would say yolk loom even though you say it's always in a certain position.
I personally never had a switch fail on this model, in fact i never had a switch fail on the 24,25,40 or 41
Have a good read of Beko's post.

Thank you, if being in the same position when it stops is significant when it comes to it being a broken wire in the loom ... it stops and starts in the same position even when the machine is on it's side ... either side.

It's the yoke loom - a common design fault. There is a topic in the stickies here: Dyson DC40 Brushbar Not Turning (https://manchestervacs.co.uk/DysonForum/index.php/topic,1190.0.html).

Yes i would say the cable has snapped but part of the insulation is still joined, and acting as a hinge for the break in the cable.

Aye, they do that. :icon_nod:

Thank you very much, I shall have a read and no doubt be back with a question or two

Thank you for your help so far ... I still haven't explored where the suspected broken wire might be, the close up pictures in the other threads don't give any indication to someone who has never seen the inside of one. To all you experts I can understand how it might all sound straightforward.
What I could do with is someone explaining where the wire is located ... what needs removing before you can see it ... and what needs removing to change or repair the wire.

Thank you for that ... I have read the topic you suggest but would still benefit from knowing where on the machine the broken wire is.
Thank you

Look at the black and white wire in the third picture down >>here<< (https://manchestervacs.co.uk/DysonForum/index.php/topic,3166.msg26649.html#msg26649).
That's it.

Ryevac and MVacs ... you were exactly right ... we continued using the vacuum cleaner in the until the brush stopped and wouldn't start ... the white wire was broke in two.
During the repair I inadvertently removed the screw from the clear cog and have lost the position.
Could you explain how to re-position it. The fact it moves with the tilt of the machine I need two reference points to position it properly.
Thank you

I can't remember off top of my head, however i have a dc41 to go out to tomorrow with same suspect fault so will refresh then.

Thank you

I think the dc40 is a little different to the 41 but will photograph it before and after
I didn't do mine on site as i had another job to go to and didnt want to put myself under pressure, will be doing it tomorrow am i think.
Should really photograph them beforehand if in doubt, i do as my memory is fading with age....

bugger, been a while since i did a 40 / 41 ray.
My 41 today revealed head motor fault so didnt strip main ball assembly apart from sides removal, and its different anyway.
Not able to help in this case, if you have a look on previous posts i think beko covered it on a strip / rebuild ?
-
Thank you for keeping me in mind Trev,
I found the solution a few minutes ago and will post the detail later.

ok Ray, Had a right mare with the first one i did a couple of years ago

I had inadvertently removed the screw from the clear cog while repairing a broken wire to the brush roller.
In fact it didn't matter that the screw had been removed ... you can get the cog out of position with the screw in place.
The key to the position lies with the cog having six teeth which mesh with the six teeth on the machine.
It is just a matter of having the left hand tooth on the cog in the left hand slot on the machine ... in this position the lug on the cog lands against the stop at the end of its travel.
I'm sure you will have all been doing this without thinking ... I probably made it sound more worse by pointing out I had removed the screw.

Now Solved ... Just to finish this off ... I only stripped it down far enough to find the broken wire which was repaired by inserting a 2" length of similar wire.

The Machine has worked perfectly well since
Thanks again for your help

We tend to find repairing them doesn't last that long, Ray. But you may have more luck.
Great follow up and pics. :thumbsup:
-
I fully understand ... as we speak the other wire may be ready to break :( ... at least now I know what to expect.

The new wiring looms are more flexible compared to the older stiffer wires, they should last longer :thumbsup:

fixed quite a few cables in the earlier models, most failed.
It really isn't cost effective labour vs part cost, i always liberally spay silicone into the channel the cable sits in to reduce resistance.
