My Beko WMA665W hangs after a few seconds at the start of a program!?

Our Beko WMA665W has began to have a mind of its own. Firstly the program selector switch doesn't match up with the digital read out and yesterday I switched it on and it was stuck in some random state showing 1 min on clock. I reset it by power cycling the on/off button and then pressing the start/pause button for a few seconds.
Now it starts a program and then hangs.... it will fill with water but the drum will not turn, I have cleaned the filter but still doesn't play ball.
It will drain if you set it to drain and press the start button about 7 times as it starts, resets and hangs in sucession and then works ( but doesn't release the door).
I have tried another reset:-
Power off
select 90 degrees
Power on holding the Start button in
Display shows "----"
Then power cycled the on off button again it looks like it has reset but at the start of a program hangs again!

Repeated the above but instead of Power Cycling for a second time, pressed the Start button again and all of the "display and button" lights begin flashing.
Power cycled on/off button and appears to be in the same position as I started with the program hanging!!

I know I've tried lots of combinations, any ideas out there?
thanks Paul
