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 don't need to clean the capsule, the water will flow out of the drawer instantly, without a rotating rinsing effect, which may cause splashing. If nothing is placed in the machine during cleaning, some machines may leak when emptying, as the drawer and machine may not seal properly without the capsule cap thickness. Tip: If the coffee machine is used over a long period and daily maintenance is not performed properly, internal components such as the grinder, extractor, and powder channel may accumulate coffee residue, scale, and dust. This can affect the machine's lifespan and internal hygiene. Perform thorough maintenance by disassembling, cleaning, lubricating, and calibrating core components, and replace seals and other consumables to extend the machine's life and maintain cleanliness.
