I have replaced the brushes and the machine still will not start
SOURCE: f21 fault on Bosch Classixx
Hi.
Here the reset procedure:
If that does not work, then there is still a problem. F21 indicates that problem can be motor, wiring or electronic control module. Try the reset a couple of times if that does not work at first try.
Regards.
Ginko.
SOURCE: Motor brushes replaced but fault
F21 means motor or control board fault. Usually its the motor. If you have replaced the brushes and it doesn't work then its most likely the motor is faulty. Not a cheap fix.
F21 relates to a motor or control board fault.
However, it is also caused by spikes in the mains and can be spurious.
To reset it.
Turn the appliance knob to the off or reset position, 12 o'clock.
Turn the knob to the 6 o'clock position.
Press and hold the spin button.
While holding it, turn the knob to the 7 o'clock position.
Continue holding the spin button for about 5 seconds.
Release the button.
Turn the knob to off.
When your turn it back on it should have cleared the error code
