For what this is worth, our machine was doing this too, and my husband took apart what he could and found a whole bunch of stuff just before the water pump. It was disgusting, toothpicks even a razor blade, screws, coins , you name it, if it is found in clothes pockets it was there, coated with a blue black slime. Also up where you put soap in take that apart and you might find some stuff cloogging things up. When we put everything together again the error messages stopped. Gone. Things may just need cleaning.
