Seems to have sorted the problem
Have drained machine twice now, it goes 3/4 way through cycle and then just pauses!
Asked to drain dishwasher. Did so, and it seemed to work.However, machine only goes 3/4 way through cycle and then "pauses" with a running noise. Have drained machine twice, but still get the same result.
Sorry have been away.
I have had the base off the machine - no leaks.
Also removed a number of pipes to check if any debris inside - none found.
Machine does work 3/4 way through cycle and seems to pumps out/fill.
