Product review (1 stars): Simple fix before you order this part! Shop vac the drain hose...
I ran the diagnostics for the "suds" and "F35" error codes.  It indicated that I needed to replace this part.  I ordered the part and researched a bit more.  One lady suggested vacuuming the drain hose out with a shop vac.  It sounded too easy to work, but cheaper than a $100+ part.  I tried it.  We are on load 3 and no codes.  I'm not sure this is a long term fix, but it is worth a shot.
