Zanussi FJ1295 :Programme unit going too fast , missing steps?

We have a Zanussi System 1200/FJ1295. The program(timer) knob doesn't progress at the usual pace. If you set up a program the sequence is stepped through very fast and what should take 45 mins takes a couple of minutes and of course the programme hasn't been performed properly. Does this look like a timer problem or can something else cause the same symptoms. I should add that if you set the knob to say spin or drain then nothing is done.
Awaiting anxiously for an answer.
