My washing machine is not filling up with water or completing a full cycle?

Hi

Having worked fine in the morning my Zanussi Jetsystem 1400 washing machine starts a cycle as you would expect but doesn't fill up with water and counts down by a few minutes. At this point the counter all of a sudden reduces to 3 minutes and starts filling with a little bit of water and finishes the cycle like normal.

Any suggestions what is happening??? I have cleaned the filter and all the trays etc, but still the same?????
