# According to Ashkenazim, some say that it is forbidden to use a dishwasher for meat and milk even one after the other and even if one uses different racks. <Ref>Badei Hashulchan 95:81.

* Rav Moshe Feinstein (Igrot Moshe OC 1:104, OC 3:58, YD 1:28-29, and YD 3:10-11) is lenient to use a dishwasher for meat and milk dishes consecutively with different racks. His reasoning is that the only concern of taste from the dirty dishes is Nat Bar Nat and therefore doesn't render the dishwasher meat or milk. He explains that it is permitted even initially and isn't considered like creating Nat Bar Nat. Also, he says that there is probably sixty times the beeyn in the actual pieces of leftovers on the plate. Yet, he says that a person should use different racks for meat and milk out of a concern that a piece of meat or milk got stuck onto the rack and taste directly got absorbed into the racks.</ref> Sephardim only allow using one dishwasher for meat and milk if they are used in different shifts and the dishes are first rinsed to remove the large pieces.<ref>Yalkut Yosef (Otzar Dinim L'isha p. 618), Yalkut Yosef (Isur Vheter v. 3 p. 485), Yabia Omer YD 10:4</ref>

* Shaarei Shalom on Piskei Ben Ish Chai Basar Bchalav p. 143-5 is strict for all dishwashers even one after another. If the first cycle is with soap he is concerned for the fact that noten taam lifgam is only after the fact. He quotes Tzemech Tzedek 61, Minchat Yakov 57:26, and Shulchan Gavoha 95:7 who only allow the case of using ashes to clean dishes (S"A 95:4) after the fact. Also, if the first cycle is without soap there is an issue because if the dishes are dirty everything becomes forbidden and if they're clean we don't rely on S"A 95:3 initially as Shach points out.
* Horah Brurah 95:46 discusses whether the kula of 95:4 is permitted initially but concludes like Rav Ovadia that it is permitted even initially.
* Whether the beliyot can be koshered with ashes in the water is a major dispute: Kaf Hachaim 95:59 quotes the Bet Dovid YD 41 quoting Mahariku and Bet Yehuda 114c, 2:77 hold that it is effective, while the Dvar Moshe 10, Dvar Shmuel 88, Kol Eliyahu YD 1:11, and Erech Hashulchan 95:17 hold that it isn't effective.</ref>
