AEG Oko Lavamat 72640 update - stops mid-programme?

Stopping mid-wash, and sometimes immediately after the initial usual start-up noises. Sometimes the start/pause button flashes but pressing it will not restart the machine. Having to drain and rinse and try other programmes. Now and again this works but I've spent a whole day trying to wash a load of nappies! (and now my tumbledryer's stopped working too - aagh!) What could be the problem with the washing machine?
