Thank you so much for this posting about the black hose line. We had done everything that had been posted about the drain basket in the front, the drain pump, all the other gizmos and such but this posting about the black line and it’s attachment that could possibly still be causing the F02. Sure enough this was a culprit along with the drain lines that had a significant amount of gunk caked inside each line. Once the lines were cleaned the washing machine finally did a spin cycle and finished the cycle without a single code. Thanks for posting this, we were minutes from throwing in the towel and calling a service tech.
