Hotpoint CTD80 - F15 error?

I've had this drier about 2 years now and it seems like it's continually developing one fault or another.

The latest is this little gem - F15. The drier started to slow a little and become a little eratic and about 40 minutes later it stopped altogether and came up with this error.

It's already recently had a new heater element and it's 2nd new fan - the plastic impeller or whatever at the back of the machine.

It's always been noisy and I'm totally fed up with it.
