Thanks Dave, so I have thoroughly checked for blockages(pump, pipe from pump, labyrinth,drain hose and drain it drains into)
So a few things have progressed, I have been watching the side of the machine pulled whilst it is pulled out into the room and I can see it draining and filling fine but I have seen what it is doing when it stops.
So it has got worse, current symptoms are it stops randomly (before wash, after pre rinse, later before rinse?) And beeps with the tap light on. When it does finish it also has the tap light on.
So I am stumped.
