Indesit WIL143S cycle problems?

I have an Indesit WIL 143 S. I turns on and I set a programme on the control board. It starts up and looks like its going through the cycle. Unfortunately all it is doing is filling, then rotating about 5 turns clockwise, then the same anti clockwise... thats all! It isn't going through the programme and it'll continue to do this until it's switched off. It'll drain or spin IF you select that on the control dial but it wont go into a cycle.
HELP!!!
