The lid switch affects agitation in commercial washers. The few
residential washers I've used only have only the spin disabled when the
lid is open.

Do you have a multimeter? If so, I would: 1) Unplug the washer from
the electrical outlet. 2) Pop the washer top, which usually just
requires prying with a screwdriver at the front. and 3) Test for
continuity of the lid switch when open/closed.
