That's a really weird thing. In the EU, not only is Eco mode mandatory, and must be the default mode, and you can't label any other mode "default" or "normal" to sway the consumer to use that instead... but it's also how the appliance's energy rating is calculated, and it's displayed prominently on every device sold. It would be madness for a company not to put their most efficient settings on Eco mode. https://energy-efficient-products.ec.europa.eu/product-list/household-dishwashers_en https://energy-efficient-products.ec.europa.eu/product-list/... https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv:OJ.L_.2019.315.01.0267.01.ENG&toc=OJ:L:2019:315:TOC#d1e41-275-1 https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=uriserv:... You can also see there that they're tracking the effects of their regulations and measuring how much less electricity and water is used. The regulations also set minimum standards for cleaning, drying and energy usage so you can't sell products that look efficient but require everything washed twice, nor can you even include a resource hog mod. And it mandates the availability of spare parts for a certain number of years, and access to repair information, so you don't just junk the whole object. I can only imagine "Eco" mode being worse than other modes in some place where there's not good market regulation. I just checked my own dishwasher, and its Eco mode uses 9L of water and 0.83kWh per cycle. Other washing modes use 9-17L water and 0.9-1.5kWh per cycle... so it does conform to the regulations.
