Bosch WFF 1201 takes too long !!

hi helpers my bosch WFF 1201 seems to take too long on its cycle, i put it on no 3 today at 1pm and it just finished the wash cycle at 2 20pm and usually finishes in 2 hours. sometimes it finishes without a final spin and generaly doesnt seem to wash properly ( never seems to be any foam stirred up in tub )

ive checked the filter at the front and cleaned inside the plastic container at the back, machine is about 6 years old thanks P M

Does it seem to be getting hot enough? Is it hot or cold fill?

yeh, water seems to be getting hot enough
