F01 is a motor triac fault.
What you need to do is remove the back panel and check the wiring to the motor and the control board on the side.
If this is fine then if you can remove the motor and check the carbon brushes at the back. If they have worn then they will need to be replaced.
But if they are fine then its possibley the control board as this is were the triacs are anyway. So if this is the case then the control board will need to be replaced.
But the F-01 error code is a motor related error code.
If you need anymore info just get back to me.
