Indesit WIA101 Washing machine gone loopy?

A while ago, the door lock led was flashing all the time (unless it was doing a wash, when it remained lit). Now it appears to carry out a part wash, either a wash or rinse cycle, during which the door lock led is now not illuminated. It does not drain. The door interlock is working fine, as is the filter and pump. I have checked the water level sensor with a meter and that is switching over ok. Re-setting the machine by leaving it unplugged from the mains for 24 hours does not appear to have any affect, neither does following the instructions to interrupt a wash (although it will flash the current cylcle led (wash)).

It's looking like the main circuit board is shot unless anyone has any other ideas.
