DC59 Brush not spinning
« on: September 12, 2021, 03:46:47 PM »
Hi,
   I have a cordless DC59 and the brush doesn't spin. I've connected the head directly to the handle and it still doesn't showing it's not a continuity problem in the stick.
I've stripped the head down, cleaned it, applied a 9 volt battery directly to the motor and it spins showing the motor works.
I've stripped the handle down enough to access the top contacts, pressed the button and I'm not getting any voltage here, so I presume the motor isn't getting power, and it's not even getting to the top contacts.
Could anyone please help with where I go from here?
Many thanks in advance, Simon

You've got no power coming off the bin or no power going from motor unit to the bin?

I get no voltage from the contacts on the motor unit which the bin presses against, well, 0.01v for a split second, then 0.
However, I've noticed if I put a 9 volt battery directly on the motor it spins, but if I put it on the brush head contacts it doesn't so perhaps this suggests a broken wire in the brush assembly, which would make sense if this is flexing all the time causing a wire to break.
But then I can't understand why I can't see voltage at the motor unit!

Bingo! Found the problem: this broken wire obviously due to flexing. Now, question is can I replace it? I can't repair it where it is as there's no room so I do need to replace it. Can anyone help please with this, taking the articulated joint apart to get the wire in, and putting back together. Many thanks, Simon

There's a Beko strip-down topic on those, you can see how it comes apart >here<

I worked out how to take the assembly apart, and repaired the wire with an inserted soldered piece and put tape round. However I then realised where that goes is supposed to be in two grooves and a plastic piece fits snuggly on top, and with my repair is too thick and so the plastic piece sticks up too much, so the plastic ball won't go over it.
Would some tape over my repair keep it in place instead of the plastic piece, or should I look for a replacement wire?
Many thanks,
Simon

I've repaired it as explained, but could not replace the plastic cap over the wires which doesn't effect its running, but not sure how long the repair will last.

Does any one know please whether it's possible to buy a replacement wire with connections and the 2 grommets attached? Dyson doesn't seem to sell them, just the whole head, and I can't see any on ebay.

Unfortunately this wiring loom is not available to buy. Mainly because it takes a considerable amount time and skill to do this repair, if you are doing it for yourself as you are then thatís great, good on you, however if you are a shop or business repairing a customerís machine, it simply isnít a cost effective repair when new heads are so readily available.
I can only suggest you look for a cheap good condition head thatís otherwise faulty (eg the wheels or main brush are at fault) and use it for spares
