Bosch WTE84105GB/35 Dryer

Hi
The drying, Iron dry and anti crease lights are coming up on this one
I replaced the belt as it was snapped but can’t seem to clear the fault code
I can’t find what this code means anywhere.
Does anyone know how to clear the code or what this code means please ?
Toni
PS this is how I am trying to clear the code
1. Set the dial turning clockwise to 6 o’clock
2. Hold (and keep down) the low heat button
3. Turn the dial to 7 o’clock clockwise
4. Release the low heat button
5. Turn the dial one click at a time clockwise to 11 o’clock position.
6. Turn the dial back to 6 o’clock position anti clockwise
7. Set the dial to Off (12 o’clock).
