I hate to break it to you, but even with the knobby versions, it’s still electronic under the hood. But I know what you mean about the annoying bleeps and bloops. Again, though, the Samsungs were always the worst offenders in that regard, omg…
GEs make little noise, and LGs are pretty low-key. Whirlpools and Maytags just beep a couple of times.
