Aqua stop or similar device for washing machines and dishwashers

[InFrance]

The site is obviously more focused on electrical issues and fires than overflowing and flooding, but I was hoping for some help. I'm replacing a 20-year-old Miele dishwasher with an aqua stop mechanism by a Whirlpool WFC 3C26 P (virtually new, a gift) that has no aqua stop device. Should I simply replace the intake hose by one with an aqua stop or similar device? (There's no feedback; it operates by closing when water flows in without meeting any resistance.)  I contacted Whirlpool customer service in France and asked for suggestions; they sent me the commercial spec sheet but didn't answer the question.

This is more of an issue in France, where incoming water pressure is 6 bar; I've installed a reducer to bring it down to 3 bar; but it's much higher than with a cistern.

Thanks for any suggestions.
