Hi have bosch wft2806gb/13 washer drier.Replaced motor brushes now problem with final spin it appears to build up speed then drops does this several times but does not stay on high speed for very long.The motor had to be dissasembled to replace brushes.Is the stator directional?Would this effect the final 1400 spin speed?

Motor brushes: The motor brushes may be worn out and need to be replaced. This is a common issue with the Bosch WFK2401UC washer motor

. You can check the brushes by removing the back panel of the washer and looking at the motor. If the brushes are less than 1/4 inch long, they need to be replaced

.
Imbalance: If the load is unbalanced, the washer may not spin at full speed to protect itself. This can cause the cycle time to be cut short
6
. Try rearranging the load and see if that helps.
Sensor issue: If the washer is not detecting an imbalance but still not spinning at full speed, there may be an issue with the sensor. This could be causing the washer to cut the cycle short

. You may need to call a professional to diagnose and fix the issue.

Sometimes the brushes on the motor get worn and they cause motor to act intermittently. I changed my brushes and this corrected the problem of not washing or spinning.

Had several Bosch machines do thus because they have very high speed on spins the motor brushes can become chipped and worn down especially if someone replaced them using non Bosch brushes.
they cost about £30 a pair whereas the more common ones are about £7. Now they may not look worn down but if there is a lot a black dust in and around the motor it's a sure sign something is wrong.best bet really is to go to eBay and buy a new motor as the reconditioned ones cost the same as the genuine brushes £30.but if you think you can get by with the £7 version you may another 18 months out of the machine before you have to replace.hope that is helpful.

brushes are spring loaded you take your motor out of the machine and replace them your machine will work

F21 normally indicates a fault with the motor or the main control board. It could be the motor brushes need changing.
If you've changed the brushes you now need to erase the stored errors and try the machine again.
.
Turn the knob to off.
Close the door.
Turn the knob to 6 o'clock position.
Wait 2 seconds.
The start/pause should begin flashing.
Press and hold the spin button. (the spin button is the one that changes the spin speed, it may be marked "RPM")
Turn the knob to 7 o'clock position.
Wait 2 seconds.
Release the button.
Turn the knob to off.
.
This should erase the error code and get you running again.
.
If the error code returns, you have a problem with the motor, wiring or main control.
If the machine won't go into diagnostics to erase the error code, it would suggest a faulty control board.
.
Try it several times to see if you get it reset.
.
Note, If the start button doesn't flash, just carry on trying to erase the codes.

Hi from retired Englishman in SW France,

'won't spin up to speed'- does that mean that it stays running at the normal slow speed? If so it could be motor OR control board.
If it is just struggling then it does sound as if the motor requires replacement, particularly noticeable when called upon to run the spin cycle. It is not uncommon to find that the brushes are worn sufficiently for them to not make perfect contact with the commutator at the higher speeds- bouncing and sparking. Now, a word or two of advice from this retired Englishman in SW France. It might be suggested that just the brushes on the motor want changing; experience (of others) suggests that they may only last months rather than many years UNLESS the motor itself is refurbished. Refurbishment includes skimming the commutator on which the brushes run. Without skimming the brushes do not sit cleanly on the commutator (like the worn ones!), often causing excessive sparking and excessive wear on BOTH. Alternately a new motor! I changed the motor on our 19+ year-old Bosch at a cost of GBP250 ;-0(
The choice of course is entirely up to you- but do not forget that it is not an uncommon fault, especially if the washer is not exactly new. Others I have given this advice to have chosen new brushes and I don't blame them!
If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!

Possibly the filter needs cleaning, this is located at the bottom front right of washer behind drop down flap or cover.
Unscrew anti-clockwise to remove and clean
.
If it still will not spin, then the brushes in the motor probably need to be replaced.

possibly the motor brushes.
take back panel off and motor is held in by bolts which undo - also disconnect electrical plug and socket.
check condition of brushes
