Whirlpool W10121657 Washer Drain Hose Check Ball OEM Part

Prior to ordering parts I had pulled the pump strainer basket and cleaned it out. There was both soft and hard scale build up. The tub-to-pump hose was also pretty crusty/slimey. Still got warnings for SUDS and repeated F02 errors. Ordered parts and replaced the pump, tub-to-pump hose, interior drain hose and exterior drain hose (both hoses has some slime build up). The water standing in the tub when I emptied it the first time had very little suds but we kept getting the SUDS warning. It's not clear how this is determined, but it looks like the pressure switch is involved. Suspected the pressure switch and/or sense line hose may be fouled so I replaced those as well. Replacement was pretty easy - GM/Ford should take lessons from Whirlpool on building things so they're easy to maintain! Your video on the pump replacement was spot on - it really was as easy as you said it was. Parts were delivered on the original order promise date and they were in good shape. The washer is back up and running again.
