washing machine?

zanussi aquacycle 1250 (approx 17 yrs old)! when washing - half of the washing is coming out dry and the other half is wringing when on the 50 & 40 degree cycles. But on the very hot (White 95 degree cycles) all working fine ?

no weird noises, fully completes all the cycles, spins as normal, take softner etc ???? any ideas??
