Hello . Last week i bought a delonghi evo magnifica coffee machine ( model number ECAM29X.5Y EX:1 ), used it every day , and now after one week because i saw that the coffee jet was very slow , it was basically dripping the coffee instead of pouring it continuously, i wanted to clean the coffee infuser behind the water tank. I saw on the internet you have to just rinse it in water ( not too hot ) , so i didnt use any detergent or stuff like this. After i rinsed it i could see on it something whitish and sticky , and i was wondering what is that , if its some kind of residue or its like a vaseline or something , i was wondering if i have to clean that one too. I will attach a photo below.
