Is that a thing in the US? My current dishwasher is from 2015, stock standard Ikea.
I never had to rinse anything for it to come out sparkling clean. Even in the fast program that only runs 64mins.
The other day I had an Airbnb guest from NYC and I saw him rinsing. And when asked why he told me that was necessary because the dishwasher couldn't cope with it otherwise and stuff would come out dirty.
He looked perplexed when I told him no dishwasher I used for over twenty years required rinsing beforehand.
Is this 'rinsing requirement' an urban myth sticking around in some areas of the world?
Edit: I live in Berlin but have been living in Australia, the UK, Japan and Italy over the last two decades. No dishwashers in the apartments I lived in in those countries required rinsing either.
