Resource saver, spin rinsing
There is a deep rinse cycle that could be manually selected after the regular cycle if you feel like you need an additional rinse, I guess if you had a load that was really full of grit and lint, it might be helpful. I’ve never used it.
That looks like the inlet valve I’m talking about I think the part number was 358277 I don’t think the one in the link you posted is a genuine, whirlpool valve, and I’ve seen a lot of problems with imitation valves. I try to steer clear of them.
