Bosch Exxcel Washer F21 error code

check pump

F21 refers to the carbon brushes in the motor so price new brushes - if you are handy they are easy to fit and not expensive - but if you can't do it yourself i personally wouldn't spend too much on repairing a 5 year old machine

F21 is a motor fault and in some cases can also involve a module fault. It could be as simple as the brushes need replacing or the drum has been severely out of balance.

I had F63 on Bosch washing machine (Maxx 7). I waited 5 days for a repairman and all he did was reset the washing machine processor, like this: 1. Turn the program knob to 6 o'clock 2. Hold the RPM button 3. While the RPM button is held, turn the program knob 1 click clockwise (to Rinse) 4. Release the RPM button.
This is similar to F21 which also happened to my machine. Apparently both errors are related to power surge/power cut.

i had this problem,no drain or spin,opened the flap at bottom right hand corner and pulled out small hose to drain machine opened circular filter cover (some water may come out) and found a 5p and 1p blocking filter after removing ,machine worked fine.
hope this helps

I would suggest that you remove the motor, and check the brushes for wear.
If they are less than 3 or 4mm long, then they need to be replaced.
Hope this helps.

I have a Bosch Classixx 6 1200 express washing machine showing error code F21 on the display, what is it?

I had the same problem- machiine not spinning and a few days later not turning at all. Display would go from 11min to 1min.
I did 2 things - 1) changed the brushes on the motor- cost £7.50 .
2) whilst working under the machine disconnected pipe from drum to pump and emptied it- found 2 coins in the bellows.

need more info what point in the wash does it start to display the code
