Descaling a commercial coffee machine is important to remove mineral buildup, also known as limescale, which can affect the machine’s performance and flavor quality. Here is a basic process for descaling a commercial coffee machine:

  1. Preparation: First, turn off the machine and unplug it. Empty any water from the water reservoir and remove any removable parts, such as the portafilter and drip tray.

  2. Choose a descaler: You can purchase commercial descaler specifically designed for coffee machines, or use a solution of equal parts water and vinegar.

  3. Fill the water reservoir: Fill the water reservoir with the descaler solution and reattach it to the machine.

  4. Run the descaler: Turn on the machine and let it run for several minutes, allowing the descaler solution to circulate through the machine’s internal components.

  5. Rinse the machine: After running the descaler solution, turn off the machine and empty the water reservoir. Fill it with fresh water and run the machine several times to rinse out any remaining descaler.

  6. Reassemble the machine: Once the machine has been rinsed, reattach any removable parts and refill the water reservoir with fresh water.

Note: Always refer to the manufacturer’s instructions for specific descaling and maintenance guidelines for your commercial coffee machine, as the descaling process can vary depending on the model and manufacturer. Additionally, the frequency of descaling will depend on the mineral content of the water you use and how often the machine is used, so it’s a good idea to check for mineral buildup regularly and descale as needed.
