“What has been accepted IS the Rema’s codification! “
LOL!!!
Rabbi Yaakov Emden didn’t accept it. And as I pointed out, many other codifications of the Rema have not been accepted. And the Rema never codified that massive expansion of the definition of kitniyot we’ve seen in the past generations.
“a dishwasher’s relative low cost compared to a house is reason to disregard Feif Un’s rov’s p’sak that he doesn’t need a new one”
As I said, I agree that he can follow is Rov and that anyone who doesn’t accept it isn’t Orthodox. But because there are so many people who claim to be Orthodox who won’t accept it, it may be worth an extra 1/10 of 1% of the cost of the house to get a new dishwasher. Sometimes you just have to cave in to the folks who won’t accept the halachic process in order to maintain shalom among Jews.
