* However, Ritva Avoda Zara 76a s.v. vyesh and Ohel Moed Pesach 3:3 argue with the Rashba. The Ritva has another reading of Rava and the Ohel Moed is bothered how cooking can serve as koshering if it didn’t kosher the rim of the pot. (The Gra 94:11 also argues that it could be that we reject the opinion of Rava altogether. See however many rishonim who quote Rava as being accepted: Rashba Torat Habayit 38a, Ritva Avoda Zara 76a s.v. vyesh citing Raah, Maharam Chalavah Pesachim 30b s.v. vhilchata, Mordechai Pesachim n. 563, Rosh Chullin 7:31, Or Zaruah Basar Bchalav 1:467, and Bartenura Vayikra 6:21.)

* Bet Yosef 93 argues that we don’t follow the Rashba and demonstrates it from several places where we don’t assume that cooking is considered a mini-koshering. The Shach in Nekudat Hakesef 93:1 argues that the Rashba was talking about a complete koshering, that is, with cooking food up to the top of the pot and at a complete boil. He also thinks that this is completely accepted by the poskim to allow this as hagalah and hagalah is effective for a permitted absorption for everything. Either way, the idea of a mini-koshering because of cooking food isn’t accepted. This is also the conclusion of the Hagahot Shaarei Dura 85:10.</ref>

===Pot Covers===
# If one uses a meat pot cover to cover a milk pot while it is on the fire or the opposite, the food, pot, and the cover are non-kosher. If the pot is cooked parve and the pot or the cover weren't used within 24 hours the food would be kosher and the utensil which was used within 24 hours remains kosher but the one which wasn't used within 24 hours is non-kosher. If both weren't used within 24 hours the food, the pot and the cover are kosher. If the food in the pot is meat then that makes the pot and the cover absorb taste of meat immediately even if it wasn't used within 24 hours for other meat. The same is true of milk.<ref>Shulchan Aruch 93:1</ref>
# The same is true whether or not the cover was hot as long as the pot was hot.<ref>Rama 93:1</ref>
# If one accidentally placed a hot cover on a cold pot, some say that the food, the pot and the cover are all still kosher.<ref>Rama 93:1</ref> Other poskim hold that the pot needs to be koshered.<ref>Shach 93:6, Pri Chadash 93:9</ref>

Badei Hashulchan 95:33 and Chachmat Adam 48:2 clarify that this means after the fact that the parve food was cooked in a meat pot it is considered parve and can be eaten with cheese even initially.

The same is true of the opposite case.<ref>Rama 95:2. Badei Hashulchan 95:27 explains that the reason that we're lenient about using utensils of the other type for nat bar nat is because the entire concern of meat and milk here is rabbinic since there's no combination of actual meat or milk but only its tastes.</ref>

* Pri Megadim M”Z 94:14 distinguishes between when the milk taste is absorbed completely by the rice and when regular milk is mixed together with the rice and partially sticks on the outside of the kernels or there is liquid between them. If it is just a taste that is absorbed then the milk doesn’t spread. However, if the milk is stuck to the outside of the kernels it would become absorbed into the spoon. Bet Shlomo Freedman v. 2 p. 102, Chachmat Adam 57:6, and Bet Meir on taz 94:14 agree.

# If hot or even cold meat fell into hot milk or vice versa everything is forbidden. <ref>Shmuel in the Gemara Pesachim 76a says that the temperature of the bottom item overcomes the top item and if the bottom one is hot it'll heat up the top one. The Ran (Chullin 41b s.v. garsinan) quotes the Raah who says that the cold meat which fell into milk is only forbidden up to a fingersbreath but the Ran argues that it is completely forbidden. The Rashba (Torat HaBayit HaKatzar 5b) and Rambam (Machalot Asurot 9:17, as cited by the Bet Yosef 91:4) agree with the Ran. Tur and Shulchan Aruch YD 91:4 codify the opinion of Shmuel that if a cold item falls into a hot one the top one becomes hot and everything is completely forbidden. </ref>

# If hot milk falls onto cold meat the meat is only forbidden up to the depth of a peel. Sephardim hold that the milk is permitted, while Ashkenazim hold that the milk is forbidden unless there is sixty times the area of contact to the depth of a peel.<ref>The gemara Pesachim 76a says that if hot milk falls onto cold meat the meat is forbidden up to a peel. Tosfot s.v. tanya quotes Rabbenu Tam who says that the milk isn't forbidden at all since it is impossible to remove a peel of a liquid. However, the Riva is quoted by Tosfot as disagreeing and stating that the milk is forbidden unless there is sixty times the depth of a peel where the contact was made. The Tur 91:4 infers from the Rambam that he sides with the Rabbenu Tam. Shulchan Aruch YD 91:4 holds like Rabbenu Tam, however, the Taz 91:7 and Badei Hashulchan 91:34 are strict for the Riva. </ref>

This concept can be found in the Maharsham 3:208 though that isn’t his conclusion and advises being strict. Yavetz (1:93) is lenient and is adamant about this issue.

* 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) only allows consecutive cycles. Yabia Omer YD 10:4 allows meat and milk dishes together. Rav Ovadia himself in the new edition of Yabia Omer 10:4 fnt. 6 added that it is better not to follow his teshuva to do it at the same time. Rabbi Assayag and Rabbi Wiesenfeld in Kashrut in the Kitchen Q&A p. 91 rule like Yalkut Yosef.
* 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.
Magen Ba’adi 1:19 of Rabbi Matloud Abadie writes the exact same argument as Rav Ovadia. Or Letzion 3:10:11 in footnote implies the same position.
* 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>
