Question:
Are you allowed to use a slushee machine on shabbos that was prefilled before shabbos and comes on, on shabbos day with a timer to have slushee's at the kiddush ?
Answer:
Hello,
Yes, you can use the slushee machine by filling it before Shabbos. If possible shlush should be taken out only while the compressor is running, to insure that it will not cause the compressor to turn on.
Best wishes
