Hi all
I have a Bosch Classix 1200 Express washing machine
E-Nr. WFO2466GB/05
FD 8407 609529
Anyhow I replaced them about 6 months ago but they've worn down again, I
think I paid about £16 for them.
The man in the shop assured me they were good ones although they never had
a number printed on the brushes as the originals did (can't remember now)
but I was expecting longer use.
The commutator! looks and feels smooth (spindle that contacts with the
brushes)
I've seen some advertised at around £38 but I don't honestly know if these
are any better than the last!
At a guess I'd think that the more expensive ones are denser/harder! is that
correct?
01...What is the key to good value for money replacements?
02...Should I be looking at carbon percentage or something like that?
03...What do the numbers printed on the carbon mean?
Example...The 2 sets of brushes below are suitable for this model
(WFO2466GB/05) £8 replacement and £38 original. If the original ones last 5
times longer then I have no problem getting these,
but in any ones experience does this equate? And what is your advice thank
you.

any of my washing machines and the motors haven't died on any of them.
They've all live to a ripe old age and only been replaced because of
incontinence or programmer problems. Is this unusual?

I did stop using one after 35 years that developed some sort
of gearbox problem that I didnt even bother to look at too
closely because I had another available to use instead.

Nope, but then I dont have a house full of little kids and need to wash every day either.

about every three years.
The Bosch Classixx is, I believe, one of the made-not-in-Germany range. I
think they are probably in the kind of Hotpoint range in terms of build
and cost.
Incidentally, the genuine brushes are available from Bosch online for
£33.84 plus £4.99 carriage. They are pretty quick getting them to you.

Is it clean? There shouldn't be anything other than minimal deposits

on it. Have you looked at it when running? Is there much arcing, that
will erode brushes PDQ.

I've not seen a gearbox in a washing machine in a very long time.

Sounds like you got a substandard part. I'd just get a replacement
from anywhere else.

It happens that p.mc formulated :
Brushes last for many years in an otherwise good motor. Since you say
the comutator looks and feels smooth, that leaves only three
possibilities: bad brushes, wrong model brushes or a bad motor wire
connection.
The defect in bad brushes would be soft material. I'm guessing this is
not the problem because it seems to me it would not be cheaper to make
brushes out of a softer aloy. I've never heard of such a thing, but I
suppose it is possible.
The likely culprit is arcing. That could be caused by brushes that are
not wide enough to span the gap between the comutator contact areas.
That would cause arcing. But that defect would be noticable. I don't
think you would fail to notice that the new brushes are half the width
of the old ones.
The more likely cause would be a disconnected motor winding. That
would cause one or more of the comutator contact areas to be dead.
That would cause arcing every time a brush leaves that comutator trace
and connects to a hot trace. I think you need a new motor.

Reinspection would show burning on the commutator metal surface.
