Imagine a dishwasher that cleans a single dish in a few seconds. You could wash and put away in similar time to loading a regular dishwasher, and capacity would no longer be an issue. Taking something from being a process to being a single step in a process can have huge impact to how we do things and what is possible.

Commercial kitchen ones, one single tray load, washed in 120s, comes out hot as fire so they air dry quick.

The good reliable ones cost about $10K USD though you can get less reliable ones for $4K. You can’t run more delicate common household tablewares in them because they run so hot, nor can you use common detergent from the supermarket, they use more energy though some of the newer ones can use very little water (about 3-4 liters per load), they’re loud for the couple minutes they run their cycle, and parts and repair services are available for longer than residential models. In a home, they’ll never cost justify themselves but I still want one despite the trade offs.

It also says a lot about how the author relates to restaurants, where a faster dishwasher is a selling point. Faster is separately important from throughput, because if it the takes 3 hours to run the dish washer, that’s a lot of plates that need to be washed and stacked all at once for a restaurant, and a lot of dishwas…

Tbf, commercial dishwashers are totally different type of device than home dishwashers.

Wow, that breaks back some sense memories (scalding hot water that actually felt kind of good) from a Hobart dishwasher of this type I used many years ago.

Hobart machines really test the limits of “dishwasher safe” - I’ve seen them crack large glass mugs just from how quickly they heat things up.

Of course, they’re mainly a sanitizer.

While I agree with the author that engineers tend not to solve customer problems, but technical ones, what I was hoping he would get to is how to actually go about finding problems to solve in the first place. In my personal journey, this has become the most difficult point in doing any sort of side project development. Sure, I can build prototypes, but for who? And why?

I think dogfooding (where applicable) and actually talking to other potential customers is most important. It helps in context of spending your resources to make more impactful improvements for your existing project (like building a cheaper dishwasher instead of a faster one).

With that in mind, it really helps to find your niche and converse with others in that niche. If you go to a niche forum like arcade museum or arcade projects, you might find people saying "I wish I had something to enable auto-fire on my arcade cab" and also people with the knowhow to build it and turns that into a product, or people having an interest check for a product they've developed for themselves to see if it has a wider audience.

Yeah, I often also do parties, where I cook for 20-ish people, and often have 3-4 dishwasher loads after a party. Speed does matter some. Where it matters a lot more is that I live in an condo where officially I'm not supposed to run my dishwasher after 10:00 p.m. The difference between 1 or 3 hours is significant there for running it after dinner. (I basically only run it after 10:00 p.m. after parties; got a very q…

Good lord. I don’t even know 20 people… at least not well enough to have them over for dinner.

I don't care about more private or decentralized? Better yet, my mom doesn't? I in fact do, and she in fact should!

It doesn't matter unless you can convince people to use it, )or legally force it on them, causing them to hate all technology because you didn't make it good enough people chose willingly).

Private and decentralized stuff needs to get feature parity, be free as in beer like Google is, and then get a killer app that makes people want it.

I've always thought p2p offline lan messaging would be it, but Blockchain trashed all research on that aside from new tokens for like 10 years. Maybe they'll figure it out, but I suspect AI filters and random games will be more important.

Unfortunately, people who like making private apps hate most features, and think privacy is enough of a killer app for people to switch, but it doesn't seem to be.

I have a small counter-top dishwasher. It gets water by hooking hoses to the sink's faucet. When it is in use, the faucet is unavailable for something like two hours. It is better than having to do all the dishes by hand. But we have to make sure we've done things like refil the water pitcher before running the dishwasher. And there's only so much hot water in the hot water heater before it runs out, so we need to ma…

Why is it using water the whole 2 hours? Doesn't it recirculating it for a while with a pump? Can you get one that does?

I dunno, man, I just plug it in and hit the button and it runs. I'm no plumber, I just got the one that got the best reviews on Wirecutter. I would describe it as a black box that I put dishes, detergent, and water into, and usually get clean dishes out of, except its housing is white.

It's probably not actually pulling in water for the entire two hours. But it wants to be able to pull in water at several points during its cycle, as well as squirt it back out into the sink, and I have absolutely no interest in trying to guess when it would be safe to disconnect the hose and risk having it piss a bunch of water all over the kitchen (because the hose got left somewhere) or having it error out because it can't get water when it needs it.

I haven't worked in a kitchen in thirty years, and I can still recall the feel of my skin after even a half shift of working next to one of those dish cleaners. As envious as I am of their speed, I'm absolutely sure I don't want to reproduce that sensation at home.

My dishwasher manual specifically tells me not to pre-rinse.

Commercial dishwashers sterilize dishes with high heat and steam. It's expected for dishes to be sprayed first by the person doing dishes with a high pressure hose to rid solid food before wash cycle. Consumer dishwashers instead let enzymes do the work. So, different applications.

Sure, but I was responding to the commenter saying you really should pre-wash at home too.

My dishwasher (LG) plays a cheerful tune to let you know when it has finished its cycle (60 mins) At least its not too obtrusive, and it only does it once. But.... then it has a cooldown timer, and if you open the door within the next 30 mins it LOSES ITS SHIT at you, beeping and carrying on because the dishes haven't finished drying. I mean... Why play the happy tune to announce to the world that you've finished...…

Our LG oven plays all sorts of fucking tunes for preheat, timer done, etc. The only tones you can disable are button presses and microwave done. Also, it is a dual oven, and the top half is also a microwave. The problem is that the top half oven functions insist on being given cooking times after baking modes preheat. (99h99m is my usual go to, which causes it to round down and demand a second “start” keypress). The…

Yeah for an oven I want on/off and temperature setting. I can time what I’m cooking separately. For a dishwasher I want one button: start. So many things are overengineered with useless or even annoying features.
