My wma 520 w Beko Washing machine keeps cutting out?

Within less than a minute of trying to work my washing machine keeps cutting out. I've tried a couple of different cycles, but it cuts out on all of them. This first occured half way through a wash and the whole of the washing machine moved and jumped about so thought it was the drum / bearings / support springs etc. Everytime we tried it, the same thing would happen and the whole machine would move However we have had the top off and "jiggled" the drum about and this now no longer happens, yet the machine will still not go through a cycle. Any ideas?
