Bosch WFO2464GB – Will not spin

[Moggs206]

We have a Bosch WFO2464GB

Not sure how old. User Reviews on the web suggest this model was about 2003 but my wife does not think it is that old. It must be at least 5 years.
It is a well used machine and has been trouble free.
I am reasonably good at cleaning or replacing replacing parts but dont think I have had to tinker much, if at all ,with this machine.

Now, suddenly machine will go through a full and satisfactory wash cycle but will not spin or attempt to spin. This is not intermittant and I have tried on spin only with light items and on empty. So does not appear to be a load distribution issue.
When I trying spin only, time remaining is 11 mins ( which I suppose is whay you expect) machine churns gently as the apparent preamble to spin. But the time then jumps to 1 minute remaining before operating door release in the normal way.
There are no unusual noises or other signs of the machine attempting to spin.

I would appreciate any guidance on what to investigate.

Thanks
Richard

Sounds like you need new motor brushes-use the search facility and look at the forum FAQs.
There is also a nice video which takes you through the procedure.

Re age of machine the FD number will tell you the manufacturing date(rear label or inside door rim) 8410 decodes to Oct 2004 for example 8803 would be March 2008 etc

Thanks for that.

Actually as I was already into trying to replace bushes when I saw your reply.

I got stuck taking out the Motor. The top two securing points (screw bolts) came out ok . However the bottom two securing points are different I am not clear whether they are unidentified heads ( I have a good range but none are effective) or are bushes that will tap out. One head is plastic or plastic covered they other is metal.

So I have attempted the brush change with the motor in situ.

Of course the visable brush was fairly easy. So I know how it goes.
However the other side is hidden and I have to do it blind.

I have looked at the “Penguin 45” video where he is doing this with motor removed. Even he has to fiddle about a bit so its not suprising I am having a problem try to do it blind.

Now with the fiddleing the clip has brken frm the connecting wire. I will have to try to solder this ( presumably that should be ok ? ) before returning to the puzzle tomorrow.
By the way, the old brushes were well word so fairly sure that this was the problem (before I drained the alligator swamp).

Nay comments / suggestions gratefully received.
Thanks again

The motor is only secured to the drum with 2 x 10mm headed bolts so i don’t know what other screws/bolts you’re talking about ?

Once the two bolts are removed , its a case of easing the motor off ( with maybe a little leverage )backwards towards the rear plate .

POWER OFF IF INVESTIGATING

Re: Bosch WFO2464GB – Will not spin

Thanks , that is helpful, if puzzleing as i have definitly been looking at another 2 securing ( or supporting) points. But they are different to those headed bolts I have removed so they are probably different in nature.

I will continue tomorrow.

Thanks

Re: Bosch WFO2464GB – Will not spin

I think you are having problems with the two rear supporting posts
which are sleeved with a black rubber bush(ie both sides)
You need to take a suitable flat blade screwdriver and gently prize between
the drum and the metal and you will find the motor drops away.

Be careful as you can easily drop the motor as it can come away suddenly
and trap a finger etc.

Check a few of the other Bosch posts -buy some reasonable quality laminated brushes and a bit or wet and dry
and you should be up and running again soon!

Let us know how you get on…………

you can see the bushes in the image at 303 below

Re: Bosch WFO2464GB – Will not spin

Thanks for all the help last night.
Following the guidance I was this morning easily able to remove the motor and fit the second brush. & reassemble.

Everything seemed to have gone very smoothly

except , to my horror it has made no difference to fact that machine still refuses to spin. I have tested on a full cycle and spin only. It seems exactly the same as when I set out in that it works perfectly in all other respects but will not spin. No noise as if it were trying to spin.
Time remaining indicator usually skips straight from say 11mins to 1 min before shutting down normally.

Could I have replaced brushes wrong edge way around. Is this critical ?
Would m/c still work to the extent that it does if I had got this wrong?

If this is likely issue I am not confident enough about motor removal ect to try again.

I have read something about brushes “needing to bed down”. Is it worth be being patient.

Thanks
Richard

Re: Bosch WFO2464GB – Will not spin

Just reread my last post. I meant to say that ” I AM confident enough to try again “.
My typo would have completly changed the sense and tone of my post.

Sorry , and thanks for bearing with me.

Re: Bosch WFO2464GB – Will not spin

From what you say the brushes are not making good contact.

In my experience

1.Use wet and dry on each brush so that they slide in the holder very easily

2.Try and match the angle of the replacement with the old-I find pairing them together and then using wet n dry works for me

3.Make sure the longest edge of the brush is on the connector side.

Finally check resistance through the pair of brushes with a meter-anything above 2ohms for solid carbons and about 4ohms for laminates tells me there is good contact.

You can also check the variation across the brushes by watching the readout when turning the motor by hand
Probably more than 0.5ohm variation and the brushes arent making good contact and need re working on the contact angle.

Hope this helps!

Yes and probably.

If you look at your new brushes you will see the end is angled, not straight. If you look on the motor you will see the two brush holders are set slightly at an angle to the commutator, also not quite straight. You need to put the brushes in so they will be “flat” against the commuator, e.g. if your brush holders are angled \ then brush must also be angled _

While you’re there also check the commutator isn’t damaged by spinning the motor by hand and running a clean finger along the copper commutator contacts – if any are raised or damaged then it’s new motor time.

Re: Bosch WFO2464GB – Will not spin

I have spent the morning taking out the motor again , using wet & dry to aid the slide in holders , & match the bevel to the old brushes.

I reseated the brushes using the advice re “longest edge on the connector side”.

After reassembly I tested spin only on all 4 spins , worked perfectly.

The machine is now back in situ with wife doing a full wash cycle. ( it has built up) seems to be working fine although I will still be a bit nervous as it approaches spin.

But I think we are sorted. Many thanks for all the advice and patience.
I am proud of us all.

Thanks again, without you it would be new machine time.
