DC25 floating head doesn't lock itself when vacuum is in upright position. It floats down when vacuum is tilted backwards.
What might be a problem?

No, machine stands up. Looks at this picture for details.

Looks like "Spring Mount Assy" (53) or "Moving Cover" (54) are dislocated/broken... Going to investigate it further.

Our DC25 is doing the same thing. Did you discover how to fix it so the brushbar head stays locked when you lift up the vacuum?

Typically this would be >>this part<< that is needed.

I have this exact same problem on a DC25. Right after it happened, I found one of the small black hex-head screws, plus a plastic washer, on the floor nearby. I inspected the vacuum in detail everywhere I could see, into all the nooks and crannies without disassembling anything, but could not see anywhere where this screw had come from.  :'( 

I'm wondering if it might just be that I need to disassemble a bit, and re-fasten that screw. Any thoughts on that? Or any further info from the original poster about what the solution was?

Silly old 25s and thier parts that fall off. I had a machine where the main pivot sheared, and a new spine was gonna be $150! Ended up being a breaker.

Could well be, there are a few strip down threads on the forum, you might spot where its from if you look at them.

This is a common problem with DC25's and is a very simple fix.

The issue is the small screw and washer would have removed itself from the black sprung cam on the upright lock assembly. If you remove the ball housing you can get in there to pop the cam back and replace the screw and washer.

When replacing these, I use a little loctite to stop it happening again.

The reply from mrdyson in this thread is correct, so thank you sir for your advice. I wish I had taken some pix when I repaired it. It was indeed a spring-loaded cam or lever that had popped loose when the screw and washer came loose and fell out. That spring-loaded lever is located to the right side of the ball if you're holding the vacuum just like you were vacuuming the floor. In order to get at the screw hole, I had to remover the ball/motor entirely a fairly difficult thing to do. I managed to get it out of the way and only had to disconnect 2 wires in the process. As suggested, I used some Loctite on the screw when I replaced it.

Also, on the posting by MV Claire with a link to a part, that doesn't look like the part that had come loose on my vacuum (bought in USA in 2009).

I have just done the exact same repair as above, using a replacement washer and torx screw to re-secure the cam and spring. I managed to do this without motor removal by removing the ball casing (both halves) and then undoing the right hand side of the yoke. It's a bit of a struggle, but this will give you just enough room to get a torx driver onto the screw that secures the cam.
So far, so good. However, on reassembly I tested it and found that, while the upright lock now works fine again, the brushbar did not spin when the machine is reclined (but it did spin when the brushbar reset button was held down). So the motor is OK. Next, I'd suspect the reset module, but the coincidence of it failing when I did the upright lock repair is just too great. So I'm assuming that whatever causes the brushbar to power up when the machine is reclined was damaged during reassembly. But what? My strip down method did not require any cable removal or electrical components to be disturbed, so I'm at a loss to see what I might have done wrong. Can anybody point me in the right direction please?
