Can a dishwasher be used for both meat and dairy provided that you use soap? Can it have both meat and dairy dishes in it at the same time?
is there a problem since dishwasher uses very hot water ?
Not a problem in the scenario described above.
Can you explain why? (Thank you)
There are many reasons why its not a problem, all delineated precisely in Rav Abadi’s sefer Ohr Yitzchak.
To list just a few…
The mixture of dirty foods, is by itself a totally unappetising combination and can not be considered that the plate “swallowed” a non kosher combination of milk and meat.
Additionally the milk and meat mix together with soap which renders it inedible and so what the plate “swallowed” is technically not even a food mixture.
And there is plenty more to allow it as a first choice.
Thank you for explaining.
The same with even non-kosher?
Does a kitchen sink rule the same?
And lastly, will a translated/wiki version of Ohr Yitzchak ever be a thing one day?
Not necessarily. There are some differences between mixing milk and meat (both kosher), and mixing kosher and non-kosher.
You can have one sink with meat and dairy dirty dishes in it.
That would definitely be a great thing.
