Hotpoint CTD80 Tumble dryer - Fault F 09

[catsomany]

I have a condenser tumble dryer which has come up with the fault F09
What is it?
I am unable to clear the fault
I have cleaned the filter, condenser and emptied the water box
Is it a fault that can easily be repaired or does it need an engineer
The tumble dryer is about four years old
Thanks
