When the machine goes to spin it stops?

I have a Arthur martin /Electrolux washer dryer AW21275 and it has always worked fine till today. I noticed that it wash not progressing. I can open the door and I can turn it off and re set to other programs but each time it starts to speed up to spin it stops and looks as if it is working but it and the timer does not progress. I have cleaned the filter, tried to run it without a load and the same happens as it starts to spin it stops. Any ideas as to what might be the problem or what I should do?
