Hotpoint WD62 washer dryer not drying?

Hi,

I have seen a simalar question on here, but it didnt really have an answer! My WD62 has stopped drying. The fan motor still works as i can here it kick in. I presume that the element has just gone, or something simalar.

DOes anyone have any idea how big a job this is? i am pretty technically adept, so hopefully it wont be a problem.

WHat are the common causes of this?
Thanks for any response.
