It seems like it would be trivial for the machine to pump water in, turn on the heating element, and wait until it reaches optimum temperature before beginning the cycle.

This is what most (all?) of machines do. Heat water when they need hot water

Read the manual of your washer. I’m willing to bet it instructs you to run the tap until it’s hot before you start the dishwasher. This is common for American dishwashers, because they can’t get the water hot enough, fast enough, for the prewash cycle

Thanks for the summary. American dishwashers don't have their own heater? All dishwashers I've seen in Australia only have cold water supply.

This has always struck me as dumb, as until recently it was far cheaper to use your existing (gas-fired) hot water than to use a resistive element. However, with gas going out of fashion (and already hugely expensive in the Eastern states), and abundant solar PV, the calculus has changed.

The problem is that the first few litres of the water coming from the hot water pipe may be cold or warm. Therefore adding a resistive element is a better solution to guarantee a specific temperature.

I wouldn’t use rinse aid. It’s not good for you - damages your gut and may contain dioxane byproducts. I also would avoid detergents with ethoxylated alcohols (AEs). What to look for is any powder or powder-filled pod with a) no AEs and b) does contain amylase and protease , two food-eating enzymes that are often omitted for who knows why. 365 Whole Foods brand pods are my go-to

The guy in the video disagrees with you. From his other video, 23 mins in, > next, rinse aids. use them. this isn't a scam. I'll trust the dishwasher expert until there's some proper citations. You have to realize that every time you sip a glass or eat off a surface that's provided by a commercial entity, you're getting items that have come in contact with industrial appliances that dispense rinse aid. I have a diffi…

I went to my Costco right before they banned phosphates in the dishwashing detergent and got a pallet of Cascade with 5% phosphates. People looked at me like I was was crazy. I'm still going through my pallet 15 years later and my dishes are always clean :-) I just throw a bit of the detergent in the tub for prewash rather than put it in the cup, as it will leak out anyway. One thing you could probably do for the phosphate-free stuff is to add a "teaspoon of TSP" to the detergent and that would probably help - not sure if the formulation in today's detergent would agree with it though. I'll find out in another 5 years I guess....

His specific thesis is that pods fundamentally clean worse than powder because they're inherently single-stage releases of detergent in machines designed for two-stage releases. Despite this, he still explicitly says that pods have their uses. So I'm unclear on how his goal is "proving that everyone is wrong." Did we watch different videos?

Is there list of machines that designed for two stage releases?

Even if it doesn't have a specific prewash section you can literally just toss a bit of powder in to the machine, since the prewash happens first.

This has been his stance for a long time. He has a lot of dishwasher videos for some reason! One thing I can't get a good answer to is whether the "prewash" step is universally the case or not. I have a good Bosch dishwasher and there's no compartment for a bit of pre-wash detergent. I don't even know if my dishwasher cycle has a pre-wash step. I would assume the dishwasher manufacturer knows what's best. The owner's…

What your manual says is common to most dishwashers. You can tell if your dishwasher has a pre-wash cycle if it does a short run, then you hear it draining, and then it does a longer full run. I expect it probably does. Also, you can always add a bit of detergent to the main compartment of the dishwasher for prewash. The normal detergent compartment has a lid so the the detergent stays dry until the main wash cycle,…

> Come to think of it, if there is a latching door on the detergent tray, your dishwasher definitely has a prewash cycle, or else they’d skip the door entirely

Alec also mentions this briefly in the linked video; if manufacturers could avoid the cost of a latching mechanism, they absolutely would. Its presence means a pre-wash cycle exists.

Hah! I had watched this just last night. I have a Fisher & Paykel Dishdrawer so this prompted me to check the instruction manual and sure enough, I had been putting Rinse Aid in the pre-wash area. I don't even really know what Rinse Aid is honestly but it's fun having some things be a black box. Turns out the correct spot is turning a knob, pulling it out and pouring it down a hole containing a glowing red light. I h…

Do they make a powder?

Pods work great for me, and I love not having crumbs of powder under the sink, or a bottle of liquid detergent with encrusted drips down the side. It's just gross. They are more expensive, but I buy them on sale at Costco for about $16/100, so at $0.16 per load I really don't care if powdered detergent is only $0.03 per load or whatever. There is clearly a revealed preference for pods among consumers for these things…

With pods you can’t add some detergent to the prewash while adding the rest to the main wash cycle. That’s the thing that makes one of the biggest differences.

You can still add powder to the prewash dispenser.

American dishwashers are typically hooked up to hot water. Some will have heaters but they're not that powerful and they may only run for the main wash cycle

Not true. Dishwashers get cold very often.

American dishwashers are always hooked up to the hot water supply. It’s right in the installation manual, and I’ve never seen one that wasn’t.
