Don't most washers and dryers have timed start like dishwashers do? I always remember mine having pictures like that but maybe that's just not a common thing

Delayed start is common for washers but not for clothes dryers (as you really don't want wet laundry just sitting there in the appliance for hours..)

Pretty common in dryers as well.

They turn over and blow cold air periodically to prevent them getting stinky.

but why???? If i have already gotten off my ass to go throw the clothes in it and so I'm literally standing right next to it, in what universe won't I just press "start" and instead press a bunch of buttons to set up a timer?

If you want to run it overnight, or while you're at work, so it finishes as you arrive and doesn't leave the clean clothes in a clump for hours (or so it runs during cheaper power hours)

>and doesn't leave the clean clothes in a clump for hours

As opposed to having your clothes be in a wet clump for hours? Between the two choices I'd prefer it being dry, because I know at least there will be less microbial activity.

Yep that.

30p/kWh in the day, 12p/kWh at night.

Dry an entire load for less than the cost of a Day Rate kWh, simply by pressing the "delay" button a few times.

In Japan, most regions have cheaper electricity at night, sometimes at up to 50-60% discounts. That might be a factor as well.

It’s not common to have separate units here though. Much easier to setup a wash/dry cycle timer.

They also sell combo units (mostly for small apartments), so you don't actually have to move the clothes to one from the other

Remote start, and finish notifications, are genuinely useful things.

At the same time, I don't know if they're actually worth the downsides of needing to create an account, having hackable IoT things, installing an app per appliance brand (at least), etc vs, say, a timer and/or delay.
