Once you've taken the coffee maker apart, you can get a very good sense of how it operates. Here are the basics of how it works:

Once plugged in, the control board takes inputs from the 5 buttons at the top of the machine.

Once the mode has been selected, the control board sends electricity through the heating element (17.3 Ω). The heating element is metal and sits right underneath the metal heating plate which keeps your already dispensed coffee warm from the bottom of the kettle.

The very same heating element has a channel through the middle and is connected to two rubber tubes. These tubes guide the water from the reciprocal into the heating element, which boils the water.

The tubes then carry the boiling water up to the top of the machine, into the coffee filter where the water mixes with coffee grounds and is dispensed into the cup.

It is interesting to note that many of the elements that interact with the heating system and boiling water are plastic, making plastic leaching a potential concern.
