Installing carbon brushes on Bosch WFK 2401

Please can you describe exactly what the machine does?

Here are main possibilities
motor brushes need to be replaced -most likely

defective motor control board
loose connectors
also..
motor tach (determines if motor is moving) circuit failed (unlikely but still possible)

I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

It is likely that the Carbon Brushes of your Bosch washing machine need replacement. Get them from your nearest Bosch Spares stockist (P/N: 154740) Replace these on the motor armature, and it will be alright again. To be certain that it is indeed the Carbon brushes, open your washing machine and look on the motor (opposite side of the pulley) There has to be 2 grayish chalk type brushes running on a copper armature, these brushes have a lifetime of about 4 - 6 years before being diminished.

Hope this helps

Sound like a prob with the control board controlling the motor, could be expensive .

Check the carbon brushes on the motor.

it may be the belt is loose, can you hear the the drum trying to turn? if so its the motor, take the belt off the motor and see if you can spin the rotor it should spin easily

To change brushes in Bosch motor.
Remove rear panel of washer, undo 2 screws that secure motor at front end, remove motor plug, lever motor back with a screwdriver or similar, and remove motor retaining a hold on it,\ so as not to drop it .
Replace brushes fitted at rear end of notor.
Refit motor and belt.
Plz rate my solution.
Thanks.

If it runs o/k with the switch held in .\then all youneed is a new switch.
Plz rate my advice.
Thanks.

oooops - the motor was stuck under the carriage. Once
moved it came off easily.

this sounds like it is a relay on the module (main pcb) if the carbon brushes have been fitted correctly then there is a fault on the module, these items are replaced as a unit, i would also look to see if the machine has a capacitor fitted, this also could have the same effect and would be a much cheaper repair to start with, a capacitor is normally situated at the top where the mains wire enters the machine, its normally about 2 inches long and 1 inch round with 2 wires from it, work with safety unplug before doing anything
