I bought an "analog" washing machine (I can't believe I just wrote that) because of simplicity. The more complicated something is, the more difficult it is to repair, and the more potential points of failure there are.
Buy a used older model if you need a machine. Because it's cheaper, because it is more basic in its components, because those parts are probably cheaper to buy and replace yourself if need be, and mainly because someone is selling it at its age because it STILL works. Anything tied to a circuit board with a processor is a time bomb.
You will not get a washing machine without processor, let alone PCB. Processors also hardly ever fail. It is stuff like the voltage conversion which powers the logic side, the actual power switches for the motor, capacitors or simply stuff that corrodes.
Does an old school washer dryer that runs off timer relays / knobs / push buttons really have a CPU? I ask because that's how mine is and I haven't had to look at the controls but they seem dead simple to me. I get there's different cycles but some simple ladder logic should be able to handle that, no? Half the world runs on simple machines like that.

Nope, it's just a timer-drive. cam triggering switches. The physical cam IS the CPU.
We have reached a point in time where there are adults who think everything that runs through multiple steps must have a microcontroller, because only really really old machines* do without.
*For the most part. I bought a brand new whirlpool dryer late last year, and it has a mechanical timer in it.
Thanks. I have an LG washer and dryer, electric. They seem to work great now but I can't see them working well for years. It's been about 3 years now. My oven is maytag and we love it. Def. Keeping this in mind.
My electric bill changed by less than $2 per month when I installed an "inefficient" washing machine. It was so little that I'm not sure the washer was the cause. That's $72 over a period of three years. The machine it replaced was just out of warranty and needed a $200 drain pump.
