How Does a Coffee Maker Work?

A drip coffee maker starts working from the water reservoir. This method involves heating the water to the right temperature. It then pours the hot water over the coffee grounds.

The waterheats to almost boiling point at about 90.5°C – 96.0°C using a heating element. The hot water enters the pipe. It then eventually pours over to the coffee grounds.

The coffee maker doesn’t boil water. It can only bring water to almost boiling point. The temperature above is the best brewing temperature. It heats the water that brings the right aroma and flavor to the coffee grounds.

The coffee maker has a simple brewing process. It all starts with the water reaching the right temperature to go to the pipe.

Can you Really Put Hot Water in a Coffee Maker?

Never put hot water in the water reservoir because hot water may dissolve contaminants in the pipes. You should put cold or room-temperature water in a coffee maker.

Hot water will make your coffee grounds bitter. It’s because hot water dissolves coffee grounds faster. This is the main reason why coffeemakers are programmed to heat water only to a boiling point to produce a balanced and consistent taste of coffee.


Never put hot water in your coffeemaker. It only makes your cup of coffee bitter. It also keeps your filter basket from overflowing and damaging your coffeemaker.

So the next time you wake up, only use cold or room temperature water for your coffeemaker. This will make your precious coffee taste the best-brewed coffee, while extending the life of your coffeemaker.
