Ordered the parts kit (switch plus hose). Watched video. Followed the steps, running back & forth between machine and the video, pausing vid after each step. It worked out fine.
I took extra time (80 min) because space in laundry room was very cramped. An issue when taking the outer white housing off the machine and getting it out of the way.
Minor issue: My washer previously had 5 water levels (X-small, small, medium, large, super) -- not that they were working. After install, new switch only has 4 levels. Knob positions do not align with the tic marks on the dashboard. It is a small variance in the new part vs. the original. I don't really mind: the machine is back in business.
