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 actually flow out of the drawer instantly, with no rotating rinsing effect, and will splash and run. And if you don't put anything in the machine while cleaning it, many machines will leak when emptied because the drawer and machine won't clamp tightly with one less capsule cap thickness. Tip: If the coffee machine is used for a long time, the daily maintenance is not serious, the internal parts of the machine, such as the grinder, extractor, powder column, etc. can not be seen, the used coffee grounds, scale, dust, etc. will remain, affecting the service life of the machine and the internal hygiene. Carry out in-depth maintenance on the coffee machine, fully disassemble, clean, lubricate and calibrate the core components, and replace seals and other consumables. Extend the life of the machine and keep it clean and hygienic.
