Rabbi Aryeh Lebowitz

What's the problem?

You did everything before Shabbos, it's happening on its own on Shabbos.

And the Gemara gives two answers.

Answer number one is, yeah, but a mill makes a lot of noise.

And Avshamilsa and Sabig B'Zayon, to have such a noisy machine running on Shabbos, that's where some of the posts came before the dishwashers got so quiet to run the dishwasher.

It used to be very loud.

So some of the posts can talk about dishwashers being a problem of just excessive noise.

The other answer, the Gemara says, is that price of hal shito b'shamay.

So the Rishonim...

Havimah Chokas, are we concerned with noisy machinery on Shabbos?

And Rav Moshe has a famous, I don't know, famous, but he has a comment in Rav Moshe, that if you could hear it in the next room, then it's too noisy.

Okay, but these, so based on that Gemara, your Kelim Dumalacha for you on Shabbos, that is fine, unless it's very noisy, and obviously these photo frames are not noisy at all.

So what would be the problem?

So Rav Shechter Shelita, Morenu Rav Shechter Shelita, assumes that if a Malacha didn't start before Shabbos, if the entire Malacha is happening on Shabbos, meaning you may have set up the system by which this Malacha will happen on Shabbos, you may have set up the system on Erev Shabbos, but the Malacha didn't start on Erev Shabbos, that's where it's a problem.

And he bases it on a passage of the Rambam, which later discovered a passage of the Rambam that Rav Zevin wrote,

I actually wrote about it in Isham Vashitos, where the Rambam was me-yashav this stira by saying there's a difference between a mill and an irrigation system.

The irrigation system was already working on Erev Shabbos.

It was already doing the malach on Erev Shabbos, and it's just continuing.

The mill is grinding new wheat already.

on Shabbos.
