AEG OKO-LAVAMAT 70530 washing machine stops?

When I push the start button, the machine goes through a few seconds of normal start-up (door lock, pump and water sounds) then pauses and will not proceed. Start/pause light flashes.

I've tried various cycles and settings with same result.

AEG OKO-LAVAMAT 70530 machine is around four years old. Bought in Belgium.

Also I do not have a manual and would like to know where to download an English language one. ServiceForce does not have it.
