I spoke to two rabbanim about it: R' Chaim Davis (founder of the Toronto<br>
Community Kollel, the Yeshiva Gedola of Passaic [where R' Meir Stern is<br>
now RY] and Passaic's Beis Medrash laTorah) and R' Jack Love (who<br>
teaches halakhah at YCT).<br>
<br>
My first conversation with RCD focused on the question of whether there<br>
is zei'ah (which I mis-called "hevel") without boiling. This was the key<br>
issue to RJL as well.<br>
<br>
My second conversation with RCD focused on whther the vapor would be<br>
yad soledes bo (simple experiment shows it wouldn't -- hold your hand<br>
a fraction of an inch above the cup) to treif-up the coffee maker anyway.<br>
<br>
RJL pointed me to sources.<br>
<br>
Rama 92:8 appears to limit the problem of zei'ah to a pot used as a lid,<br>
and there the zei'ah is yad soledes.<br>
<br>
The AhS (108) says the Rama is only writing about thick steam. (That being<br>
the point of a lid.) This might be an issue with a microwave, though,<br>
because the walls can get dripping wet. But I don't know of anyone who<br>
still (now that their workings are better known) says microwaves don't<br>
need kashering.<br>
<br>
The coffee machine is okay.<br>
