summary:

The creator argues that most dishwashers are designed to use a pre-wash dose and a main wash dose of detergent, a fundamental often ignored by single-dose pods, and presents independent ASTM testing confirming the new powder matches or exceeds the performance of a leading premium pod. The video also features a detailed demonstration using temperature logging and peanut butter to stress the importance of purging cold water from the hot water supply line before running a dishwasher, particularly in North America, to ensure the water reaches the optimal enzymatic temperature needed for effective cleaning. This is further reinforced by showing how adding pre-wash detergent dramatically improves the initial cleaning phase, especially with fats and oils.

Thanks for the summary.

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

They do, but they are generally confined to 10 amps, so they do not heat quickly.

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

They do. I didn't realize this until my natural gas supply company decided to replace my meter on a Friday. Without alerting me ahead of time so that I could, you know, plan to be gone while my house had no hot water.

Whenever natural gas supply is turned off in the US, for any reason, only the gas company can turn it back on. And they can't do so if there's a leak at all. You have to call a plumber to come out, detect the leaks, and fix them. After that, you can call the gas company to come back out (but not on a weekend) to turn it back on. And a same-day request for service requires someone to be home ALL DAY after it's called in.

And this is how I ended up showering at work for three days that week after not having had one over the weekend.

A dishwasher cycle is usually only going to run for a specific period of time. Its more effective it if starts that time closer to the proper temperature rather than relying on waiting for the heater to get the temperature up to that time. Especially on the pre-rinse cycle, where the heater may or (probably) many not engage.

I've found it harder and harder to find powder dishwasher detergent in my country. I think they intentionally pull them off the market, I used to buy a large Finish container and now I can barely find a place that sells _any_ sort of dishwashing powder.
