I just picked up a fairly clean DC25 All Floors for £20. It was advertised as all working OK except having a jammed wand, which it did-the usual issue with these. However on stripping it down to clean, I found the HEPA post motor filter to be absolutely black with carbon; impossible to wash all of it out, so have ordered a new filter.
The main motor appears to be working fine, along with the brushbar motor, so I can only assume that the motor was replaced, but the HEPA was not changed at the same time. Or is the motor about to expire on me?
Not sure which year the DC25 was released, but quite likely that it was a warranty repair, so how come the HEPA wasn't changed as well?
This is the first ball model I've had, so will reserve opinions on it for now.

If it was done under warranty it would have had a new filter.
Have you tested the motor to see if its sparking?
-
Not yet, because I haven't yet worked out the correct sequence for motor removal on the DC25. Clearly very much more complicated than the DC01/04/07...
What I was wondering was whether the motor could possible shed that much carbon without blowing? I've never seen a HEPA filter that clogged.
I've ordered a few other parts from you and will reassemble with those and see how it runs.
-
If you switch the machine on without the HEPA filter in place and you should be able to see how sparky the motor is through the gaps in the motor bucket.
Should help give an initial indication before you take the whole thing apart...
-
Thanks-now why didn't I think of that? Obvious really (with hindsight)!
I'll check that tomorrow.
-
Now tested and no visible sparking from the motor at all. Bit of a mystery, but I'll fit the new HEPA and monitor it.

All running fine still, but I have a further query on the DC25 please. How much do you have to strip down to fit a new Yoke Loom Assembly?

Obviously the left side cover comes off (3 screws) to disconnect the two wires, and then there are two screws on the top of the yoke just behind where the cleanerhead mounts on. Can you extract and refit the loom from that stage, or do you have to take the yoke off completely for access?
I've been studying beko's excellent stripdown guide, but that doesn't tell me which parts need to come off to do certain tasks (like the above, and also a motor change). And, just as importantly, which parts don't need to come off. This is the first ball model I've worked on, and the extra complexity (compared to the DC01/04/07/14) is such that I'm reluctant to dismantle more than I need to to do certain jobs (on the basis that putting it back together again will be challenging).
It would be great to see a step by step guide to changing the main motor on this model (so far all I've done is strip down and recondition the cleanerhead motor). There's a sticky for the DC15 motor change, but not for the DC25 as yet.

Iirc it was pretty damn buried. Could you take the brushroll assy off, and wire the new loom straight to it before stropping the old one out?
Other than that, never had just a loom out, sorry!

The yoke and ball will need to come off. Once this is off, the ball needs to come out of the yoke as there is a final screw that needs to be undone and it will make it a lot easier to remove the yoke loom.

Thanks, that's what I'd suspected. It's not needed at present, but looking at the way the yoke loom wiring is routed and has to flex, it's pretty obvious that it won't last too long before it fails.
So a step by step covering yoke and ball removal would be handy for both loom and main motor replacement, which I guess are the most common repairs done on the DC25 (after brushbar motor replacement of course)?
I can't believe how fragile this model is; I've changed both the brushroll and the end cap due to them being partially melted due to a build of long hair on the brushroll clogging it all up-I was surprised that the brushroll motor was still running. And the cyclone seems to clog with fluff very quickly around the shroud, even after cleaning it with hot water.
Having said that, the suction does seem very good now I've done a reconditioning and put clean filters in..
