Why You Should Clean and Maintain Your Automatic Coffeemaker

はじめに

There is a common misconception that coffee machines don’t require maintenance. This isn't true. In many machines, the brewing unit is removable, making maintenance easier. Jura machines make excellent coffee, but the machines have to be opened to access the brewing unit. Mold develops where it is warm and humid - a coffee machine can provide very good conditions for this. This guide will show you how to prevent this. Regular maintenance - especially of Jura appliances - is essential.

This guide uses the Jura E8 as an example for a thorough cleaning process. While not all steps are strictly necessary, they help ensure the machine is thoroughly cleaned.

Over time, your coffee machine might start producing coffee that tastes off, possibly due to lack of maintenance. Regular cleaning and maintenance are crucial for ensuring your coffee tastes great and your machine operates smoothly. This guide will walk you through the steps to disassemble, clean, and replace necessary parts of a Jura E8 to address issues such as mold, water contamination, and general wear and tear that can affect the taste of your coffee.
