I saw that I can use a SodaStream on Shabbos, but I have a specific question: Can I use a Sodastream on Shabbos if it has an LED indicator? If not, is there something I can do to it to make it usable on Shabbos? Would putting tape over the light perhaps help?

  • @IlanKatz Just because you can't see it, doesn't mean it doesn't exist Commented Feb 7, 2014 at 21:58
  • @ShmuelBrin, but you are allowed to open your refrigerator on shobbos. It has a light.

    @DoubleAA by covering the light it's lo ichpas lei, not lo neicha lei, and subject to a machlokes rishonim, unless having the light covered is somehow detrimental. Commented Feb 9, 2014 at 3:45

    @YEZ Fine, but it's not as nonsensical as Shmuel is making it sound. It's a psik reshei delo ichpat lei on a derabanan/minhag. (BTW having the light on draws current and presumably wastes a little money...)

You can remove the battery and than there is no issue. here is the way to do it. US wont tell you but i found this on a Australia website



I was asked this very question by my daughter who also has a Soda Stream model with LED indicator lights. But the model I saw does not run on electric power, but the lights automatically are powered by the action of the soda canister which is fed into the machine that carbonates the water. So I thought you could argue that since my ultimate desire is to carbonate the water (permitted by such authorities as Rabbi Auerbach and the author of Shmirat Shabbat K'Hilchoso) that the automatic LED display which lights up is a "Davar She'eino Tzrichah Legufah"...in other words, is a secondary act which happens not because I want it to happen but which is a result of my primary act which I do want to happen. Much like when you pass a house on Shabbat with security lights which will automatically go on once you go near and pass by the house, even though you do not wish them to go on, you could similarly argue here that the lights are not a necessary part of the desire for carbonated water, and therefore something which you cannot avoid,. and therefore could be permitted.

  • This case isn't an ein gufa case. This is a psik reisha case. An ein gufa case is a case where the entire action itself is a melacha. An example would be like digging a hole for the dirt. The digging itself is a melacha but it isn't biblically prohibited because it's an ein gufa.however in this case you are carbonating water which isn't a melacha and the secondary outcome is a melacha which makes it a psik reisha d'lo nicha le. Same with the case of the motion detector lights, you are walking which isn't a melacha and the outcome is the lights going on as a result of a permissible action. Commented Mar 18, 2014 at 21:03

If you don't need the light then it's permissible, because it's a psik reisha d'lo nicha le

    Who says a pesik reishah delo nichah lei is allowed? Virtually all poskim argue on the aruch! Mechaber, Rema, etc. Commented Mar 18, 2014 at 21:59
  • In this case it's definitely permissible, because this case is about an LED light which MOST poskim hold isn't אש. So it's a shvus dshvus. Commented Mar 18, 2014 at 22:28
  • Ramo only permits when there's a double derabonon, and sometimes not even then. See law about cutting cakes with letters. Siman 340 I think. Either way, poskim are afraid that electricity is midioraysa when there isn't a need. See reb Moshe about microphones. Commented Mar 19, 2014 at 1:03

    They only fear it's d'oraisa regarding a heated element like an incandescent light bulb, which according to the rambam even if it is considered אש, it would only be an issur derabonon because your your not heating the filament to mold it into a shape like a black smith. LED lights don't heat up, derabonon right there, it's a psik reisha d,lo nicha le, so we have a shvus d shvus Commented Mar 19, 2014 at 1:43

    @IshPloniViKohen Many Briskers actually rule like the Aruch because IIRC Rav Chaim Soloveitchik thought the Rambam ruled that way as well.
