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 action, which may cause splashing. When no capsule is present during cleaning, some machines may experience leakage due to improper sealing between the drawer and machine, as the absence of a capsule reduces thickness needed for a tight fit. Tip: If the coffee machine is used over an extended period without proper daily maintenance, buildup from coffee grounds, scale, and dust may accumulate in internal components such as the grinder, extractor, and powder channel. This can affect machine hygiene and reduce its lifespan. Performing thorough 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.
