The coffee maker’s switch turns power to the heating element on and off. To keep the heating element from overheating, there are also components such as sensors and fuses. In coffee makers, sensors detect if the coil is getting too hot and cut off the current. Then, when it cools down, they turn the current back on.
They all work by heating water and running it through pressed coffee grounds at high pressure. Manual machines require you to control all the variables, including tamping, creating pressure, and water flow.
How does a coffee machine work step by step?
Water is pushed by the pump through pressurized tubes through the heating element so that by the time it reaches the coffee it is at the perfect temperature. The hot water is pushed through the coffee grounds in the K-cup and out the bottom so that it goes through the spout and into your cup.
Inside a drip coffee maker, a very thin stream of water is pumped past this heating element. The water is heated to the right temperature super-quickly because it’s such a small amount of water, and as the newly-scalding water flows past the heating element, the water following right behind it is heating up.
