Then the dishwasher should be run, with its racks, at its hottest setting, so that any absorbed <strong>\u1e25ametz<\/strong> is released, <strong>ke-bole\u2019o kakh<\/strong> <strong>polto<\/strong>.<sup><a href='#_te01ftn11_5' id='_te01ftnref11_5' class='aup1'>[5]<\/a><\/sup><\/p>\n<div>\n<hr size=\"1\" \/>\n<div>\n<a href='#_te01ftnref11_4' id='_te01ftn11_4'>[4]<\/a>. The year-round status of a microwave is explained in <strong>Peninei Halakha: Kashrut <\/strong>25:11, n. 12. Regarding the plate, some say that according to Sephardic custom, the glass plate does not absorb, so cleaning it is sufficient (<strong>Yalkut Yosef<\/strong>), whereas according to Ashkenazic custom and <strong>Ben Ish \u1e24ai<\/strong>, the plate is considered meat, dairy, or <strong>\u1e25ametz<\/strong>, depending in which food touched it. Based on what we explain below (section 14) and in <strong>Peninei Halakha: Kashrut<\/strong> (32:5), one should be stringent, as stated above, since this level of intensity is similar to that of a <strong>kli rishon<\/strong>.<\/p>\n<p><a href='#_te01ftnref11_5' id='_te01ftn11_5'>[5]<\/a>. Some are stringent and consider dishwashers to have the status of a <strong>kli<\/strong> <strong>rishon<\/strong> on a flame. This means that to kasher a dishwasher one must put a white-hot piece of metal in it in order to bring the water to a boil. However, those who follow the lenient approach have authorities on whom to rely. Others are stringent about this because they have a custom, <strong>le-khat\u1e25ila<\/strong>, to kasher everything in a <strong>kli rishon<\/strong> on the fire. So state <strong>Igrot Moshe<\/strong>, O\u1e24 3:58, and <strong>Sidur Pesa\u1e25 Ke-hilkhato<\/strong> 8:32. However, in practice, a dishwasher should not be considered a <strong>kli rishon<\/strong>, because only where the water is heated up is considered a <strong>kli rishon<\/strong>. However, from there the water is injected into the hollow center of the dishwasher, and when the water arrives there it has the status of something poured from a <strong>kli rishon<\/strong> \u2013 and <strong>ke-bole\u2019o kakh<\/strong> <strong>polto<\/strong>. Regarding what Rema writes, that there is a custom to kasher everything in a <strong>kli rishon<\/strong>, this is only <strong>le-khat\u1e25ila<\/strong>, and even then, it is only due to the concern that the <strong>kli<\/strong> may have been used in a more intense fashion. In the case of a dishwasher, there is no such concern; this is the accepted ruling (<strong>Hagala<\/strong><strong>t Kelim<\/strong> 13:225-227; <strong>Or Le-Tziyon <\/strong>3:10:11 states that technically it is permissible to kasher just by cleaning).
