i have a Beko AA class WMA 520W washing machine and it won't wash, when i put it on a wash cycle it will fill up wash for about 7 mins then drain, neither will it spin unless i actually turn the

Had the same problem this week. i bought the machine of a mate and was ready for kicking his head in, but thankfully before then i found that this method resets the washer, hope it works for you also
Turn power button off (not at wall)
Select 90 degree wash
Press Start / Cancel button down for 3 seconds and turn power button on whilst still holding buttons down - Start light will flash.
Leave power on.
Select any Spin position.
Press Start and Cancel button at same time again for 3 seconds - other buttons may start to flash - if they do, press Start /Cancel button again for 3 seconds.
Machine should be re-set ready for use
