There are a number of methods used to descale an espresso machine, depending on the make and model. Descaling regularly is key to maintaining a high level of quality within the flavour of the espresso you produce and extending the life of your machine. You should be descaling your machine at least three or four times a year to avoid the unwanted buildup of limescale, coffee residue, and other harmful bacteria.
There are many factors that can hinder the quality of your coffee, including not maintaining a regular cleaning routine. Here are some of the key reasons why descaling your espresso machine is so important.
One of the first signs that your espresso machine needs descaling is a noticeable change in taste. As scale builds up inside the machine, it affects the water temperature, which in turn impacts the coffee extraction process. Low brewing temperatures lead to low extraction yield, resulting in weak, under-extracted coffee. Conversely, high brewing temperatures cause over-extraction, making your coffee bitter and harsh.
Scale buildup reduces the water temperature over time, leading to an overly acidic and unpleasant brew. For anyone serious about their coffee, maintaining a consistent temperature is key, and regular descaling ensures your machine performs at its best. Using filtered water can also help, as it reduces the minerals that contribute to limescale buildup.
Limescale is not just a taste issue—it can lead to serious mechanical problems with your espresso machine. The scale can build up to the point where it obstructs the flow of water inside your machine. If the pipes become clogged, water flow to the brew head and steam wand is restricted, making it difficult to brew coffee or steam milk effectively.
In extreme cases, the scale can completely block the pipes, preventing the machine from producing steam or milk at all. The machine may also struggle to detect the correct water levels, leading to overfilling, overflowing, and potential damage to the boiler. Regular descaling helps prevent these costly issues, ensuring your machine runs smoothly and reliably.
If your office is based in a hard-water area and you use your espresso machine up to six times per day, we recommend descaling your espresso machine every three weeks to avoid scale buildup. However, if you’re in a soft-water area, descaling every three to four months should suffice.
Some espresso machines come with automatic descaling cycles, pulsing water through at regular intervals using a full reservoir of water and taking up to 20 minutes to complete. But if your machine doesn’t have an automatic descaling option, you’ll need to do it manually. Here’s a step-by-step guide to help you through the process:
By following these steps, you can ensure that your heat exchange espresso machine remains in peak condition, delivering great-tasting coffee every time.
If your machine has an automatic descaling cycle, refer to the manual for instructions on how to descale the machine. For those machines without an automatic cycle, here’s a step-by-step guide to help you through the process:
