Re: Indesit WIDXL126 fault
The brushes are worn and the commutator does not look great which is probably why the new brushes have not lasted. Time for a new unit I think, it has been hammered for 6 + years.
Thanks for your comments.

“The leading edge brush” 😕 they are both leading, er, or both trailing, depending on which way it is rotating?

Thanks, strange that they trail when motor rotates one way and lead when it rotates the other way, perhaps it is the high speed mode that dictates though why should they lead when in high speed mode?

Your challenge now (should you wish to accept it though?) is, what direction does your CESET motor spin at full speed then? Clockwise? or Anti-clockwise?Does it spin OK?Challenge accepted 8)
It spins anticlockwise from the commutator end, i.e. with the brushes leading, which I would have thought would promote wear – hence my original question – spun full circle 😉 .

Yes….Your description was incorrect, take a close look next time at the brushes and you will see (and I refer you to my first post here) one leading one trailing whilst rotating clockwise, one leading and one trailing anti-clock.
You’re not convinced are you
Yes, I am not convinced because my description was correct. Your input is appreciated though 🙂
Look again at the top picture in my link, at the position of the two brushes, it is as I said – if the motor rotates one way both brushes lead and if it rotates the other way both trail.
One explanation that has been suggested to me that the motor will only run at high speed in one direction.
Many thanks.
Re: Electric motor design question?
Hi,
A CESET motor in an Ariston:
I have found this link:
http://www.emersonappliance.eu/washing_ … motors.htm
It is as per the top picture exactly, as you can see from the position of the two brushes, if the motor rotates one way both brushes will lead and if it rotates the other way both will trail.
Any thoughts?
Thanks.

It’s called ‘leading edge and trailing edge’. At any one time with a fully reversing motor it has to be like that to ensure sufficient drive torque.
Hi,
That is clear however both brushes are angled towards the rotation of the commutator (leading) so when the motor reverses both would be trailing, surely one angled towards the rotation and one against would be better so it is the same (one leading, one trailing) whichever way the motor rotates?
Many thanks.Re: Ariston Margherita 2000 AWD12 washer dryer
Hi,
Thanks both, point taken though I have only moved the brush housing about 1mm, just enough for the spring to exert some force on the brush. Aside from anything else it was useful in that the fact that all worked fine afterwards confirmed that the brushes were the cause of the problem.
I will take the motor out to look at the brush type shortly however.
Regards.
Re: Ariston Margherita 2000 AWD12 washer dryer
Hi Jim,
Many thanks for all of the info. Having modified the brush that was at its limit it is back together now (and currently running ok) so I will have to take it apart agin to look more closely. I might just wait until it packs up again which it surely will because I only achived about 1mm extention on the brush.
Thanks and regards.Re: Ariston Margherita 2000 AWD12 washer dryer

Hi, Thanks for your help, both 105214 and UN12101 look physically similar and the model number is not listed under either p/n. Also it is difficult to tell by the angle of the end of the carbon. In the two pics the carbon is retratced in one and extended in the other though the angle appears to go the same way on both.

Stopped working again!
Same symptoms, so I figured that the loose connector on the PCB was probably knocked by me when I took the motor out and that it was the cleaning of the commutator that solved the problem before.
So I took the motor out again and realised that one of the brushes was at its limit, I have managed to adjust the brush and it is working again thus proving that the brushes are the issue however I am not sure which are the correct ones, I think they are p/n 105214, the third ones down on this page:

Can anyone confirm?
Many thanks.
