Q. See prior question – (Can I take out on Shabbat from the dishwasher dishes that were already washed if no light goes on or off). What if the dishwasher was still working at candle lighting time can you take out the dishes on Shabbos?

A. 2) If the dishwasher was left on during the complete bein hashmoshos (from sunset’s beginning until the time stars came out), since at the time Shabbos entered it could not be opened and it was muktza then, it will remain prohibited for the rest of Shabbos. (See O.H. 308: 3 and 279: 2). However, Horav Shlomo Miller Shlit”a pointed out, that if by mistake someone opened the dishwasher, it would be permitted to use the dishes, since the rationale of “Miguy Deiskatzoy Leben Hashmoshos Yiskatzoei Lekulo Yomei” (If it became muktza at the beginning of Shabbos it remains muktza for the rest of the day) does not apply to the dishes, as they were not muktza on their own accord. This being similar to the case of a totally enclosed storage facility that collapsed on Yom Tov, where Shulchan Aruch (O.H. 518: 9) rules that the fruits are permitted. (See Mishna Berura ibid. 45)
Horav Shlomo Miller’s Shlit’a opinion is that in need, you may ask a Gentile to open the now muktza but inoperative (no lights go on) dishwasher in order to extract the dishes.
