The cleaning chamber is specially designed to allow water to circulate through the capsule drawer and disperse through multiple small holes in the side wall of the cleaning capsule, creating a rinsing effect. When no capsule is present, water flows out of the drawer quickly without the rotating rinse action, which may cause splashing. If no capsule is inserted during cleaning, some machines may leak when emptying, as the drawer and machine may not seal properly without the capsule cap's thickness. Note: With prolonged use and inadequate daily maintenance, internal components such as the grinder, extractor, and powder chamber may accumulate coffee residue, scale, and dust, which are not easily visible. This buildup can affect machine hygiene and reduce its lifespan. Performing thorough maintenance, including full disassembly, cleaning, lubrication, calibration of key parts, and replacement of seals and other wear items, helps extend the machine's life and maintain cleanliness.
