Nespresso capsule coffee machine Descaling

Professional barista communication, please pay attention to coffee workshop (Weixin Official Accounts cafe_style) One day when brewing capsule coffee, I found that the machine flow rate and Crema were not up to 40ml, because the standard amount of normal standard Espresso (small cup button) was 40ml Lungo (large cup button) standard amount was 110ml, so when I went to Xinguang Mitsukoshi to buy capsules that day, I followed suit.
