@malwaretech The first cycle indeed just rinse, but that is not useless as there are lots of stuff which is removed that way. It also uses cold water, so that the powder will not be much effective.
Most dishwashers can operate this "rinse" cycle alone, you can see for yourself how effective it is. I normally operate it if I only have half a load so that the dishwasher will only be run the next day.

I would doubt advices from TikTok, in general.

@dl2jml @malwaretech it's your lucky day https://youtube.com/watch?v=jHP942Livy0 @TechConnectify did a comprehensive video on how to best run a dishwasher and why, if you're into that kind of kinky shit

Please do not ask me to watch youtube videos.

I don't like videos, they normally take 10 minutes to tell me stuff which can be written in 2 sentences.
I am not interested in "influencers", I don't believe someone's opinion is more valuable because of more followers.
I won't like or follow, because I don't have a google account.
I hate advertisement, either official or slightly disguised as a video.

Thank you.

@dl2jml @raven667 here's the tl;dr to the video. The first cycle is SUPPOSED to be hot, and it's supposed to use detergent.
This isn't a life hack, this is how dishwashers are designed to work.

@raven667 @kevingranade The first cycle in European dishwashers is cold and without detergent. Heating water uses a lot of energy.

European dishwashers use typically 0,6-0,8 kWh per wash and are only connected to a cold water inlet.

@dl2jml @raven667 @kevingranade For what it's worth my Canadian dishwasher is hooked to hot water and uses 400-600 wH for a 2h31m cycle. Add on whatever energy is used to heat 15 litres to the temperature that constitutes "hot, but safe" water here, which is done by a gigantic gas boiler in my apartment building's basement.
