Hi, Firstly, after researching the forum I found out that the fact that my washing machine has stopped spinning could well be down to the brushes. So I took the motor out and released one of the brushes from the white holder and out it came! Only about 1/2 cm long - so I reckon that's worn right down. Trouble is I forgot to notice which way it came out i.e. Which way round it should be replaced.

It has a slant which has to go one way up or the other. Anyone got any tips as to how to work it out? If I put the brush back in the wrong way up will it cause damage?javascript:emoticon(':(') Sad Secondly, I think the part I want is listed in your shop as: BS12103 - Bosch & Siemens Motor Carbon Brushes. Finally, do I really need the Flexible commutator cleaning stick? It seems a bit expensive. Can't I clean it with a cotton bud or something -or do I really need to bother cleaning it at all. One last question - the machine is around 7 years old?

What is the likely life span of the machine? Because I notice a lot of noise when the pump is working these days. Many thanks SM Appliance Forum User Posts: 17 Joined: Mon Oct 22, 2007 12:00 am. If the one your looking at is down to 1/2cm, it's finished, so don't bother putting it back. As for which way round, look at the motor end on, and you will see that the white brush holder is offset and does not point at the centreline of the motor. This is why the brush tip is angled.

The BS12103 brushes are correct for that motor. Com sticks - some people do, some people don't. I have one and only have cause to use it on the odd motor where the brushes are not bedding in properly. Pumps get noisey with age, as the cylindrical magnet wears the plastic housing.

It will eventually become unreliable due to the wear. A replacement can be found here: Power off at all times, please. Regards, Penguin45. I can answer the slanted edge question.

The longest edge should be on the same side as the connector that connects to the brush. I.e If the connector pushes on from the right, thats the longest side.

If it pushes on from the left, thats the longest side. You might also be able to notice that the brush housings are slightly angled onto the commutator, and its just a task of working out the right angles for the brush edges.

Hope this helps.oh, and once you've replaced the brushes, turn the motor slowly by hand. If it makes an awful 'clackety clack' sound, they're probably in the wrong way.

If the old carbon brush has worn down badly enough the copper tail will have undoubtedly scratched a groove on each of the commutator segments. It therefore is very important to clean away the groove using a 'commutator bedding stick'. The bedding stick acts as a mild abrasive to wear away the copper segments down to a perfectly smooth surface.

It can only be performed by rotating the armature and applying gentle but even pressure over the surface in a fixed position. In other words, the armature must rotate whilst holding the bedding stick in one postion. Much like a cutting tool on a lathe. The consequence of not cleaning away the damaged surface will mean that the new brushes will wear very rapidly indeed. Not only that but due to them not being in 100% full contact with the armature commutator, that will cause the armature to overheat very quickly and burn out before you've even put the second washload in!

We always use them in the trade as a matter of course. Appliance Master Posts: 26355 Joined: Thu Jun 19, 2003 12:00 am Location: Over the hill.

Bosch actually advise replacing the motor/armature if it's grooved by the brush tail but personally i think that's totally unnecessary.even on really badly scored comms i use some emery cloth first then polish with a comm stick. It's perhaps just as important though to brush out the comm with something like a toothbrush to get rid of the carbon between the segments.

Another tip is to file a small taper on the nose of the new brushes so they sit nicely in the channel worn by the old ones.
