Problem with water into Dishlex DX302 & it won't start from wash setting?

Hi all, we have a Dishlex DX302 that doesn't seem to want to pump water into the top inlet pipe now? We have pulled it apart and can't find any blockages. When we got it, after a good clean up it worked great but now it just doesn't seem to want to work properly. We also have a problem with it not wanting to start from the actual 'wash' setting now but will only start from the 'rinse' setting? We can't use most of the other settings like before either and it will only show up on the 65* temp setting showing all the lights displayed but will still only start from the rinse setting? PLEASE HELP US, my ill health depends on this working.......
