To clear an F21 error , you will need to enter the test programme.
Set selector switch to off
Turn selector switch to 6 o’clock position
Hold spin speed button then turn selector switch one position clockwise ( 7 o’clock )
The machine should now be in test programme
Turn selector switch back to off then on again and it should be back to normal
