Zanussi, TC481W condenser dryer.- Won't dry quickly enough?

Hi,
I've had this machine for about 8 years. Worked perfectly until now. Clothes are not drying or drying very, very slowly, even though they are hot to touch when I open the door. Usually dries a load in about 60 minutes but it does not make a lot of difference if I leave on for 90 mins now. Makes a noise as if it is spinning but not sure if it the reverse action is still working.
And the water receptacle is not full .

Any ideas?
Thanks
