If the original reporter could grab a packet capture this would be solvable instead of a bunch of speculation.
Although in the typical home setup with a combo modem/router and a WiFi washing machine that isn't easy to setup a packet capture.
I have a second wifi AP and a semi smart switch that i think can run a span port which i could rig to do the job, but most people don't.
There is no logical need for a network connection to wash clothes or keep your food cold. Excuses to the contrary are thinly veiled BS to justify spying.
