ent from leaking, once there is too much coffee powder left,
the seal ring will be blocked. If the seal ring is blocked, it will
lead to the espresso leakage or splash when brewing espresso.
For this reason and for healthier, we suggest you to clean it
immediately with hot water from the brewing function. If it is
not cleaned in time, it will produce a bad smell.
