Servis Washing machine Model no; M6725W?

My washing machine is filling with water and then doing nothing else, it will also drain for 5 seconds then stop, so I have had to manually drain it to get my clothes out.
I have checked the filter(clear), the ubend under the sink(clear) and had the pipe off both ends(clear) the propellor thing behind the filter is moving round as is the drum(by hand)
Can anyone help me as to what maybe the problem
Many thanks
