The chamber for cleaning the capsules has been specially designed to allow water to circulate through the capsule drawer and then be dispersed through several small holes in the side wall of the cleaning capsule for a rinsing effect. If you do not use a cleaning capsule, the water will flow out of the drawer quickly without a rotating rinsing effect, which may cause splashing. When no capsule is present during cleaning, some machines may experience leakage due to the drawer not sealing properly without the capsule's thickness. Over time, if the coffee machine is not maintained properly, residue such as coffee grounds, scale, and dust can accumulate in internal components like the grinder, extractor, and powder chamber. This buildup may affect machine performance, hygiene, and longevity. Regular deep maintenance, including disassembly, cleaning, lubrication, calibration of core parts, and replacement of seals and other wear items, helps extend the machine's life and maintain cleanliness.
