Fixed it!!!
One of the motor brushes ( the one you cant get out with the motor in the machine ) was gone. It wasnt agitating properly during the fill cycle so wasnt filling properly and part way through the cycle the pressure switch would click out again.
That's three faults I had to fix - heater was blown ( open-circuit ), the door-interlock was intermittent and the brushes were worn. Still, a fairly cheap selection this time!
