I have just replaced the carbon brushes on my Bosch classic 6 washing machine and wasn't convinced that I put one of them the right way round. The motor is now working ok but it is making a highish pitched noise when the motor is turning. Could this happen if one of the carbon brushes is the wrong way round?

F21 is motor fault - check the carbon brushes in the motor and replace if needed.

But first please try to reset the machine, turn the program knob from the off position (12 o'clock) to the 6 o'clock position and immediately press and hold the spin button. Then while holding the spin button turn the knob to 7 o'clock position and continue holding spin button for 15 seconds.

Hope this helps and good luck.

Then REPLACE CARBON BRUSHES (something happend with the commutator on the motor, in most case the brushes
But reset it to release the code BEWARE !! after change the brushes ..
1 close the door
2 program knob to zero
3 program knop to down (like on a watch as a hand pointing to the 6 )wait 2 seconds
4 Now press the speed button and keep it pressed meanwhile pressed the button turn the program knob to like its axis the hands 1one little step to the 7 like the number seven on a watch in comparison
5 after 2 seconds release the speedbutton

If all is right than there must 888 be displayed ..

Finally turn the program knob to 0

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

It sounds like a snapped belt or a broken motor. Can you here the motor run? You can access the motor and the belt from the back of the machine. If it is the belt snapped, this is easy to replace yourself. If it is the motor, you will need a repair man.

Remove rear panel of washer.
Remove drive belt.
Unscrew the 2 bolts that hold motor to tub back.
Remove motor plug
Lever notor back with a screwdriver or similar, keeping a firm hold on motor.and remove motor
At the rear end of motor away from pulley you will see the brushes and the armature.
Remove brushes, and if there is less than 4 or 5mm of carbon left, then replace them.
Lightly clean the armature with emery cloth.
Refit in reverse order. Test.
Plz rate my solution.
