Cannot open bosch Avantixx 6 door flashing f 21
Original advice in 2014 from Kenjo, on another website:
f21 is worn brushes in the motor replace them and to reset the f21 code.... close the door, turn timer dial to position 8 going clockwise, hold in the spin speed button whilst turning dial to position 9 let go of spin speed button and return dial to off position.
