I’m completely missing your point. Your original comment has been flagged so I don’t see it, so I’m missing context.
I, and I would guess most consumers, are perfectly fine with the trade off of taking longer at lower cost (energy and water). I run mine overnight so it doesn’t matter. This is what I want as the default.
On the few occasions I need it to run faster and am fine with the trade off of higher cost, I press a button and it’s there.
What’s the problem?
