I am having the exact same problem.
This is not a soap draw blockage as I have removed the draw and as the machine goes into spin cycle you can actually see water rising back up the inlet tube for the soap drawer.
So there is a blockage somewhere but it is on the drainage part.
I am taking mine apart later to day to see if I can figure it out.
If I do I will let you know how to fix it.
If you here any advice can you let me know?
