All fully automatic espresso machines have a brew unit (or brew group) and keeping it clean is essential for great-tasting coffee and a healthy machine.
Depending on your machine, the brew unit may be removable or built in. If it’s removable, we recommend taking it out about once a week and rinsing it thoroughly under the tap. For non-removable brew units, your machine may use a cleaning tablet or automatic deep-cleaning cycle instead. Manufacturers may also refer to this process as “coffee oil cleaning.”
Keep in mind: cleaning the brew unit is not the same as descaling. Each tackles a different type of buildup, so always follow your manufacturer’s recommended cleaning and maintenance instructions.
Skipping regular brew unit cleaning can lead to bad-tasting coffee, coffee or grinder blockages, mold buildup, and even machine failure.
It’s a simple maintenance step that can make a big difference, helping your espresso machine perform its best while keeping every cup tasting fresh.
