The dishwasher wasn’t draining.
I methodically (read: in a random, chaotic, increasingly raging fashion) tracked the clog to a tiny piece of plastic that had found its way into the drain near the sink.
I did not, I’m happy to report, break the dishwasher.
Indeed, I learned a lot about how the dishwasher works, and how it’s installed, something that had previously been locked in the “black box that makes dishes clean” realm.
This is good, as a broken dishwasher can plunge our household into despair.
Also good for my psyche, which has been sending me dreams about intractable infrastructure issues for the last week.
