So there are a lot of issues that are unique to coffee machines, you know, shehiya and achzara and bishel and whatever.

But part of it is just setting up a machine before Shabbos that's going to be doing malacha on Shabbos, so on the surface.

And the background is that there is a concept in Hilchah Shabbos called Shvisas Kelim, to have your utensils rest from milacha on Shabbos.

Generally, though, the halacha is that we're not concerned with Shvitsas Kehlim.

The Mishnah, in the end of the first parakh of Masech Shabbos, has a makhlokas between the Beishama and Beis Hillel, whether you're allowed to set up Kehlim before Shabbos to continue performing malacha into Shabbos.

And the Shulchan Aruch, the Simen Ration and Beis, Paschans like the Beis Hillel, obviously, who say that there is no...

that the Kli can continue to do your work into Shabbos.

And the Mishnahis give examples of setting up an irrigation system, setting up a trap for an animal.

However, the B'reis and Shabbos Tafir Chas says that yes, you're allowed to set up an irrigation system.

However, what you may not do is you may not put wheat in a water mill going into Shabbos with the intention that the mill continues to grind the wheat into Shabbos itself.

And the Gemara says, well, wait a second, isn't that just Shavissa's Kelim?

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...
